Background: Any protrusion through the anterior abdominal wall with the exception of hernia through the inguino-femoral region is defined as ventral hernia. Incisional hernia and primary defects in the abdominal fascia, which can cause umbilical hernia, epigastric hernia, para-umbilical hernia and spigelian hernia are grouped under the definition of ventral hernia. Objective: To evaluate the recurrence rate of laparoscopic ventral hernia repair with closure and non-closure of the hernia defect in non-complicated ventral hernia cases. Patients and Methods: This prospective randomized study was conducted from March, 2015 till December, 2019 in General Surgery Department, Mansoura University Hospital. It involved 50 patients with ventral hernia, who were classified randomly into 2 groups by computer generated sampling technique after retrieval of the calculated sample size according to inclusion and exclusion criteria. Results: The mean age of the non-closure group and of the closure group was 39.96 ± 6.52 and 39.84 ± 7.48 years respectively. The males were 36.0% and females were 64.0% in non-closure group, while in the closure group males were 24.0%, and the females were 76.0%. The mean BMI in the non-closure group was 31.44 ± 3.76 kg/m2, while in the closure group was 30.88 ± 3.70 kg/m2. In the non-closure group, the most common hernia sites were epigastric (60.0%), followed by umbilical (40.0%) while in the closure group, the most common hernia sites were umbilical (96.0%). Conclusion: Laparoscopic ventral hernia repair is a safe and feasible technique. The great advance in abdominal laparoscopic surgery and advance in the equipments and instruments as well as individual skills make closure of the hernia defect represents a good alternative to conventional laparoscopic ventral hernia repair (LVHR) with mesh only.

Objective: To evaluate the efficacy of intra-operative wound irrigation with normal saline in reducing surgical site infections in gynaecological surgeries. Methods: It is a prospective cohort study carried out at Obstetrics and Gynaecology Department, Pak-Emirates Military Hospital, Rawalpindi from 1st November 2019 to 30th April 2020. A total of 400 patients undergoing abdominal surgery for gynecological reasons were recruited by consecutive non-probability technique. Patients with known comorbidities were excluded. Participants of study were allocated cohort and control groups at the end of the surgery after closing the abdominal fascia. In cohort group, the subcutaneous soft tissue was irrigated with 1000 ml of Normal saline solution before skin closure and sterile dressing. No intra-operative wound irrigation was performed in the control group. The primary and secondary endpoint measures (SSI up to 10th Post-Operative day) and (SSI up to 30th Post-Operative day) respectively, were assessed clinically. Results: The study included 400 patients, with 200 in the cohort group and 200 in the control group with Mean Age of (Mean ± SD) 33.6±8.1 years. Majority of the patients had Pre-Op Hemoglobin of >11 g/dl (216)54%. Most common surgeries were Caesarean section (324)81% and Hysterectomy (40)10%. Maximum surgeries were performed between 30-30 min (312)78% with mean hospital stay of (Mean ± SD) 2.9±0.5 days. Analysis of the results showed that Intra-operative wound irrigation with normal saline significantly lesser rate of postoperative SSIs in comparison to no irrigation at both primary outcome measure that was SSI at 10th Post-operative day (POD)(RR=0.417, 95 % CI [0.15;1.161]) and secondary outcome measure that was SSI at 30th POD(RR=0.286, 95 % CI [0.060;1.359]). Conclusion: Intra-operative wound irrigation with Normal Saline decreases the risk of SSI by 58.3% (AR) at 10thPOD and by 71.4% (AR) at 30th POD in otherwise healthy women with no comorbidities.

Highlights • Lipids change overtime in normal fascial healing in the early post-surgery period. • Specific lipid species are correlated with the changes of inflammation cells and fibroblasts. • Lipid species in the present study are considered as predictive markers for the formation of incisional hernia., Background Failure of fascial healing in the abdominal wall can result in incisional hernia, which is one of the most common complications after laparotomy. Understanding the molecular healing process of abdominal fascia may provide lipid markers of incisional hernia or therapeutic targets that allow prevention or treatment of incisional hernias. Purpose This study aims to investigate temporal and in situ changes of lipids during the normal healing process of abdominal fascia in the first postoperative week. Methods Open hemicolectomy was performed in a total of 35 Wistar rats. The midline fascia was closed identically for all rats using a single continuous suturing technique. These animals were sacrificed with equal numbers (n = 5) at each of 7-time points (6, 12, 24, 48, 72, 120, and 168 h. The local and temporal changes of lipids were examined with mass spectrometry imaging and correlated to histologically scored changes during healing using hematoxylin and eosin staining. Results Two phosphatidylcholine lipid species (PC O-38:5 and PC 38:4) and one phosphatidylethanolamine lipid (PE O-16:1_20:4) were found to significantly correlate with temporal changes of inflammation. A phosphatidylcholine (PC 32:0) and a monosialodihexosylganglioside (GM3 34:1;2) were found to correlate with fibroblast cell growth. Conclusion Glycerophospholipids and gangliosides are strongly involved in the normal healing process of abdominal fascia and their locally fluctuating concentrations are considered as potential lipid markers and therapeutic targets of fascial healing.

Background Retzius-sparing robotic-assisted radical prostatectomy (RS-RARP) has improved urinary function compared with standard robotic-assisted radical prostatectomy (S-RARP). As RS-RARP spares the dorsal vascular complex, pelvic fascia, and anterior abdominal fascia, it may also lower the incidence of “neglected” postprostatectomy sequelae such as penile shortening, Peyronie’s disease, and inguinal hernias. Objective To determine whether there are patient-perceived differences in penile shortening, Peyronie’s disease, and inguinal hernia rates among men undergoing RS-RARP versus S-RARP. Design, setting, and participants Researchers uninvolved in clinical care and blinded to surgical approach surveyed 60 RS-RARP versus 57 S-RARP men with validated patient-reported items to assess penile shortening, Peyronie’s disease, and inguinal hernia sequelae following surgery. Intervention RS-RARP versus S-RARP. Outcome measurements and statistical analysis Univariate differences between the two cohorts were analyzed using Student t test. Logistic regression was used to analyze variables associated with postoperative penile shortening. Cox proportional hazards models were used to assess the risk of developing Peyronie’s disease and inguinal hernia postoperatively. Results and limitations RS-RARP was associated with less patient-reported penile shortening (41.7% vs 64.9%, p = 0.012), Peyronie’s disease (0% vs 8.7%, p = 0.020), and inguinal hernia (0.0% vs 13.0%, p = 0.004). In adjusted analyses, RS-RARP (odds ratio [OR] 0.24, 95% confidence interval [CI] 0.09–0.63, p = 0.004) was associated with lower odds of penile shortening, while a higher body mass index was associated with increased odds of penile shortening (OR 1.13, 95% CI 1.01–1.26, p = 0.037). RS-RARP was not associated with a decreased risk of Peyronie’s disease on Cox proportion hazard model; however, these models are limited due to a limited number of events in our cohort. Limitations include retrospective design, patient-reported outcomes, and small cohorts. Conclusions RS-RARP is associated with less patient-reported penile shortening and may decrease the risk of Peyronie’s disease and postoperative inguinal hernia development. These new findings add to research, showing improved urinary continence and quality of life following RS-RARP; however, a prospective study is needed to validate these findings. Patient summary Retzius-sparing robotic-assisted radical prostatectomy (RS-RARP) is an evolving surgical technique for prostate cancer treatment, which has shown improved postoperative urinary control compared with the standard technique, likely due to preservation of natural pelvic anatomy. Our findings suggest that the preservation of normal pelvic anatomy during RS-RARP may also reduce the risk of postprostatectomy penile shortening, Peyronie’s disease, and inguinal hernia., Take Home Message Retzius-sparing robotic-assisted radical prostatectomy (RS-RARP) is an evolving surgical technique for prostate cancer treatment that has shown improved postoperative urinary control compared with the standard technique, likely due to the preservation of natural pelvic anatomy. Our findings suggest that the preservation of normal pelvic anatomy during RS-RARP may also reduce the risk of postprostatectomy penile shortening, Peyronie’s disease, and inguinal hernia.

Altered composition of collagen and elastin in abdominal fascia has been linked with the pathogenesis of hernias. This has not been studied amongst Africans who have hernia presentations which vary significantly from Caucasian cohorts. The aim of this study was to determine, and compare, the collagen and elastin contents of the transversalis fascia and rectus sheath of inguinal hernia patients with non-hernia controls. Twenty-five patients with solitary, primary, uncomplicated inguinal hernia and twenty-five non-hernia controls were evaluated. Biopsies of the transversalis fascia and anterior rectus sheath were stained with Masson Trichrome and Verhoeff van-Gieson to isolate collagen and elastin respectively, which were quantified using the ImageJ/Fiji® image analysis software. Inguinal hernia patients were aged 19–85 years with a mean age of 45.2 years, mean body mass index (BMI) of 23.3 kg/m2 and mean duration of hernia of 42.5 months. Lateral hernias with no hernia defect or posterior wall defect [PL0] were the predominant clinical type. There were significantly lower collagen and higher elastin content in the transversalis fascia and rectus sheath of inguinal hernia patients [P

Introduction Chronic, large, and old incisional hernias often lead to surgical complications and major hindrances during emergent laparotomies. The most challenging stages of the laparotomy in such cases occur during opening and fascial closure. Case presentation This article explains the novel surgical technique employed for the complex abdominal closure upon concluding an emergent laparotomy on a 68-year-old female patient. This innovative technique is appropriate for patients with contaminated abdominal cavities and scant fascia who require abdominal operations in cases where biological mesh is not available or is not a viable option. Conclusion This surgical technique can help surgeons restrict abdominal contents and organs (particularly the bowel loops) and prevent migration out of the abdominal cavity during the early post-operative stages, hence, reducing post-surgical complications. The discussed surgical technique ensures that the abdominal fascia defect is limited using skin flaps. This defect later develops into a small hernia sac within a few weeks. Patients then need to have a secondary delayed elective operation on this significantly smaller sized hernia for repair using synthetic mesh., Highlights • In repairing large hernias, if there is no contamination, the best method is to repair with mesh. • In the presence of contamination and small hernia, initial repair seems reasonable. • If there is a large hernia, the use of biological mesh is a good option if possible. • In our country, due to the existence of sanctions in such circumstances, using the proposed method can be a good alternative.

BackgroundParastomal hernia (PH) is a common long-term complication in persons with an ostomy. Although the cause of PH may be multifactorial, the surgical technique employed for the creation of a stoma may be a risk factor for the development of PH. The traditional technique of cruciate fascia incision may predispose to increased pressure zones at the ostomy exit site, thereby increasing the risk of PH. A circular excision of the abdominal fascia at the ostomy exit site enables a uniform pressure distribution, thereby reducing the risk of PH. This hypothesis was tested in this in vitro experimental simulation study.MethodsThe effect of the surgical technique for ostomy creation on the risk of PH development was investigated in this in vitro experimental simulation study. The pressure development at the stoma site was compared for the traditional cruciate incision vs. circular fascia excision.ResultsThe pressure at the ostomy site was about four-times higher in the tradition cruciate incision technique compared to the circular excision technique. This finding was independent of unilateral (e.g. peritoneal) pressure application.ConclusionThe main finding from this study suggests that the traditional cruciate incision of the abdominal fascia for the creation of an intestinal ostomy predisposes to increased pressures at the ostomy site, thus increasing the risk of PH. This effect is not seen in the experimental setting following a circular excision of the fascia. Thus, this surgical aspect may be adopted as a possible means of reducing the risk of parastomal hernia in patients undergoing ostomy surgery.

Background An open abdomen is often necessary for survival of patients after peritonitis, compartment syndrome, or in damage control surgery. However, abdominal wall retraction relieves delays and complicates abdominal wall closure. The principle of the newly fascia preserving device (FPD) is the application of anteriorly directed traction on both fascial edges over an external support through a longitudinal beam to relieve increased abdominal pressure and prevent fascial retraction. Methods Twelve pigs were randomly divided into two groups. Both groups underwent midline laparotomy under general anesthesia. Group one was treated with the new device, group two served as controls. The tension for closing the abdominal fascia was measured immediately after laparotomy as well as at 24 and 48 h. Vital parameters and ventilation pressure were recorded. Post mortem, all fascial tissues were histologically examined. Results All pigs demonstrated increases in abdominal circumference. In both groups, forces for closing the abdomen increased over the observation period. Concerning the central closing force after 24 h we saw a significant lower force in the FPD group (14.4 ± 3 N) vs. control group (21.6 ± 5.7 N, p

BackgroundPrimary closure of the fascia at the conclusion of a stage laparotomy can be a challenging task. Current techniques to medialize the fascial edges in open abdomens entail several trips to the operating room and could result in fascial damage. We conducted a pilot study to investigate a novel non-invasive device for gradual reapproximation of the abdominal wall fascia in the open abdomen.MethodsMechanically ventilated patients ≥16 years of age with the abdominal fascia deliberately left open after a midline laparotomy for trauma and acute care surgery were randomized into two groups. Control group patients underwent standard care with negative pressure therapy only. Device group patients were treated with negative pressure therapy in conjunction with the new device for fascial reapproximation. Exclusion criteria: pregnancy, traumatic hernias, pre-existing ventral hernias, burns, and body mass index ≥40 kg/m2. The primary outcome was successful fascial closure by direct suture of the fascia without mesh or component separation. Secondary outcomes were abdominal wall complications.ResultsThirty-eight patients were investigated, 20 in the device group and 18 in the control group. Primary closure of the fascia by direct suture without mesh or component separation was achieved in 17 patients (85%) in the device group and only 10 patients (55.6%) in the control group (p=0.0457). Device group patients were 53% more likely to experience primary fascial closure by direct suture than control group patients. Device group showed gradual reduction (pConclusionsThe new device applied externally on the abdominal wall promoted reapproximation of the fascia in the midline, preserved the integrity of the fascia, and improved primary fascial closure rate compared with negative pressure therapy system only.Level of evidenceI, randomized controlled trial.

Purpose Alteration in fascial tissue collagen composition represents a key factor in hernia etiology and recurrence. Both resorbable and non-resorbable meshes for hernia repair are currently used in the surgical setting. However, no study has investigated so far the role of different implant materials on collagen deposition and tissue remodeling in human fascia. The aim of the present study was to develop a novel ex vivo model of human soft tissue repair mesh implant, and to test its suitability to investigate the effects of different materials on tissue remodeling and collagen composition. Methods Resorbable poly-4-hydroxybutyrate and non-resorbable polypropylene mesh implants were embedded in human abdominal fascia samples, mimicking common surgical procedures. Calcein-AM/Propidium Iodide vital staining was used to assess tissue vitality. Tissue morphology was evaluated using Mallory trichrome and hematoxylin and eosin staining. Collagen type I and III expression was determined through immunostaining semi-quantification by color deconvolution. All analyses were performed after 54 days of culture. Results The established ex vivo model showed good viability at 54 days of culture, confirming both culture method feasibility and implants biocompatibility. Both mesh implants induced a disorganization of collagen fibers pattern. A statistically significantly higher collagen I/III ratio was detected in fascial tissue samples cultured with resorbable implants compared to either non-resorbable implants or meshes-free controls. Conclusion We developed a novel ex vivo model and provided evidence that resorbable polyhydroxybutyrate meshes display better biomechanical properties suitable for proper restoration in surgical hernia repair.

BACKGROUND Negative pressure wound therapy (NPWT) has been described for closure of complex neonatal abdominal wounds, but advanced techniques for stoma or fistula control, skin protection, and the use of high pressure therapy not as well established. CASES We identified neonatal patients at our institution who received NPWT for a complex abdominal wound, defined as a wound associated with a stoma or fistula with partial or complete dehiscence of the abdominal fascia or skin. We then reviewed techniques for decreasing wound contamination and protecting the newborn's skin. One patient had an especially complex wound; she was born at ∼23 weeks' gestational age (birth weight 580 g). She developed necrotizing enterocolitis and strictures, requiring multiple surgeries to relieve obstruction, ultimately resulting in an end ileostomy with mucous fistula. She suffered from wound dehiscence and retraction of her surgically created stoma, resulting in a complex abdominal wound with significant damage to the surrounding skin. We used advanced NPWT techniques to heal her wound, including topical skin protectants, placement of an adhesive dressing over the skin prior to placement of negative pressure dressing, placement of a negative pressure sponge directly on the wound bed and stoma, diversion of enteric contents away from the wound using a Malecot catheter, and an increase in the negative pressure applied. CONCLUSION Complex neonatal abdominal wounds can be treated effectively using NPWT. The techniques we describe divert enteric contents away from the wound bed while maintaining negative pressure and protecting the surrounding skin. In addition, we used negative pressure up to -125 mm Hg and found it was well tolerated by our patients.

Objective Understanding the biomechanical properties of hernia meshes is essential in facilitating their selection. The aim of this study was to evaluate the mechanical compatibility of hernia meshes and human abdominal fascia and assess their applicability in hernia repair. Methods Uniaxial tensile tests were performed. A total of eight hernia meshes were tested - three standard meshes (Surgimesh®, Surgipro™, TecnoMesh®) and five light-weight meshes (Optilene®, TiO2Mesh™, Parietex™, Vypro™ II, Ultrapro™). Results The secant modulus at 5% strain and the level of orthotropy (the ratio between tensile stress in the longitudinal and the transversal direction) at 5% strain were calculated from the stress-stretch ratio curves. The impact of pore size and thickness on the elastic properties of these meshes was determined. The relationships between density and elasticity as well as between elasticity and the strain developed at 16 N/cm load were presented. The resulting mechanical properties of meshes were compared to the elasticity, orthotropy and deformability of human abdominal fascia. Conclusions Vypro™ II and Parietex™ brands display properties similar to those of fascia in both directions. The TiO2Mesh™ and Ultrapro™ display deformability close to the deformability at 16 N/cm of the fascia transversalis. Only the Vypro™ II brand's orthotropy is similar to that of fascia.

Introduction Loss of abdominal domain is an unsolved problem in many complex abdominal procedures. We report three patients who underwent weighted traction and use of retention sutures to prevent fascial retraction. Cases Our first patient had esophageal metaplasia and a recalcitrant esophageal stricture after having esophageal atresia repair as an infant. Due to vascular congestion of his new conduit, his abdomen was left open. Respiratory compromise was noted on attempted closure, so the patient's abdominal fascia was placed on 20 pounds of traction to prevent fascial retraction. His abdomen was able to be closed after 7 days. Our second patient had a caustic ingestion and underwent a jejunal interposition. Due to the length of the procedure, the abdomen was left open. The fascia was sutured to a silastic silo and placed on 30 pounds of traction. After 8 days, the patient's abdomen was able to be closed primarily. Our third patient presented with persistent aspiration after esophageal atresia repair. Due to concern for her jejunal conduit, her abdomen was left open and placed on weighted traction. Once the abdomen was suitable for closure, an abdominal vac was placed, and continuous fascial tension was applied using #5 Ethibond sutures. Her abdomen was fully closed 10 days later. Discussion One of the concerns with temporary abdominal closure is retraction of the fascia. We report three cases where the fascia and abdominal wall were placed on weighted traction, which allowed for retention of abdominal domain and delayed primary closure without grafts or mesh. This approach adds to the options available to aid in closure of the complex abdomen.

Abdominal injuries are potentially life-threatening and occur in 20-25% of all polytraumatized patients. Blunt trauma is the main mechanism. The liver and spleen are most commonly injured and much less often the intestines. The clinical evaluation proves equivocal in many cases; therefore, the gold standard is computed tomography (CT), which has been increasingly used even in hemodynamically weakly stable or sometimes even unstable patients because it promptly provides precise diagnostic findings, which present the basis for successful therapy. Hemodynamically unstable patients always need an exploratory laparotomy (EL). An EL should also be carried out with a positive focused assessment with sonography for trauma (FAST) or CT for severe parenchymal lesions, hollow organ lesions, intraperitoneal bladder lesions, peritonitis and organ evisceration, impalement injuries and lesions of the abdominal fascia. Hemodynamically stable patients without signs of peritonitis and a lack of such findings can often be treated conservatively irrespective of the extent of an injury. Angiography (and if needed embolization) can additionally be diagnostically and therapeutically utilized.

Resumen La ascitis es la complicación más común en los pacientes con cirrosis hepática. Las hernias umbilicales (HU) ocurren en 20% de estos pacientes y 40% en aquellos con ascitis severa. La HU ocurre debido al aumento de presión intraabdominal, al debilitamiento de la fascia abdominal y la pérdida de masa muscular. Además, tienen tendencia a aumentar rápidamente y presentar alto riesgo de complicaciones que amenazan la vida del paciente. El tratamiento de la HU no complicada es controversial, tanto el manejo quirúrgico (herniorrafia) como el manejo conservador (control de ascitis) presentan alta tasa de complicaciones, en consecuencia incrementa la morbimortalidad. Actualmente, se recomienda herniorrafia umbilical con previo control de la ascitis en el manejo de HU no complicada, reduce el riesgo de infección de herida operatoria, evisceración, drenaje de ascitis, peritonitis y reduce hasta 41% la recidiva de HU. El éxito de este enfoque también depende del grado de disfunción hepática. El tratamiento de la HU complicada es quirúrgico (herniorrafia sin malla), con menor tasa de mortalidad respecto al manejo conservador. Estudios revelan ventajas de la herniorrafia umbilical laparoscópica (mínimamente invasiva y sin tensión) en comparación a la cirugía abierta, sin embargo, aún no hay evidencia al respecto.

Surgical site infection (SSI) is a frequent complication in dirty surgery, reaching rates of up to 40%. The incidence of SSI might be influenced by the suture used for closure of the abdominal fascia. Sutures coated with antibacterial substances may reduce the bacterial load in the incision.A retrospective study of patients with intra-operative diagnosis of fecal peritonitis undergoing a laparotomy in three Spanish hospitals was performed. Fascial closure consisted in running loop suture of Polyglactin (Vicryl loopOne hundred four patients were included. There were no differences in age, gender, comorbidities, etiology of peritonitis, and mortality among groups. Surgical site infection rate was 34.6% in group 1; 8% in group 2; 33% in group 3; and 10% in group 4 (p = 0.029). The use of triclosan-coated sutures is associated with lower risk of SSI (risk ratio [RR]: 9; p = 0.003). Evisceration rate was 0% in groups 1 and 2; 15.2% in group 3; and 10% in group 4 (p = 0.05). All patients suffering from evisceration presented previous SSI. The use of monofilament sutures is associated with higher risk of evisceration (RR: 6.35; p = 0.033).Triclosan-coated sutures reduce SSI rate in fecal peritonitis, without differences between braided and monofilament type. The use of monofilament sutures is related to higher risk of evisceration, independent of a triclosan coating.

Tension-free repair (TFR) is hernioplasty using prosthetic mesh or device to replace or reinforce abdominal wall defect, without forceful pull between tissues or tissue-prosthesis junction with sutures. Open tension-free repair (TFR) is the most common groin hernia repair, representing 70% of all hernia repairs performed in the developed countries (Lomanto et al., Asian J Endosc Surg 8:16–23, 2015), the procedure is easy to learn, quick to perform, safe and cost-effective, and can be done without general anesthesia (Awad and Fagan, Am J Surg 188:9S–16S, 2004). With triple-triangles of the myopectineal orifice treated as a whole, the prosthetic mesh material could replace or reinforce the attenuated abdominal fascia and muscles without tension, resulting in minimized postoperative pain and recurrences (Jacobs, N Engl J Med 350:1895–7, 2004). The 2009 and 2014 European Hernia Society guidelines also recommend open TFR (Lichtenstein, Plug and Patch, Prolene Hernia System) and endoscopic repair as the choices for unilateral primary groin hernia for adult patients (Simons et al., Hernia 13:343–403, 2009; Miserez et al., Hernia 18:151–63, 2014).

Critically-ill patients may have their abdomens opened as a result of primary pathology (damage-control laparotomy in trauma, soiled peritoneum from perforated hollow viscus, necrotizing pancreatitis), or as treatment for abdominal compartment syndrome (defined as new organ dysfunction associated with intra-abdominal hypertension). The incidence and implications of intra-abdominal hypertension and abdominal compartment syndrome (ACS) in particular, are currently debated. Intra-abdominal hypertension (IAH) is defined as a sustained intra-abdominal pressure ≥ 12 mmHg. Grading is possible; Grade I = IAP 12 to 15 mmHg, Grade II = IAP 16 to 20 mmHg, Grade III = IAP 21 to 25 mmHg, Grade IV = IAP >25 mmHg. Management principles include reduction of intra-abdominal gas (NGT and flatus) and intra-abdominal fluid (the latter may be interstitial or intra-peritoneal), and ensuring the abdominal wall is as compliant as possible. Definitive management is to open the abdomen however, the benefits and use of the open abdomen (OA) approach are unclear. The rates of OA appear to be reducing worldwide. The reduction in the incidence of ACS requiring laparostomy may be related to global changes in resuscitation targets1, rather than changes in surgical techniques. In particular, the notion of ‘fluid de-resuscitation’ may be implicated in improved outcomes. The decision to leave the abdomen open after emergent laparotomy seems to be dependent on the surgical specialty of the operating surgeon, and is a common approach applied in victims of blunt abdominal trauma2. Complications of the open abdomen relate mainly to nutritional status and long-term abdominal complications. The most feared abdominal complication relates to the inability to close the abdominal fascia, with associated increases in mortality, fistula formation, and ventral hernias. Current critical care focus is on the prevention of the open abdomen. For intra-abdominal hypertension and acute compartment syndrome, medical management aimed at reduction of abdominal wall pressure and evacuation of intra-abdominal contents (including fluid) are cornerstone strategies. The use of neuromuscular blocking agents is controversial; short-term benefit may be outweighed by long-term complications. For the de novo open abdomen, current research suggests a possible role for more aggressive early closure (primary or before day 5, latest day 8). Further research is required to confirm whether primary closure is safe. Temporary closure techniques using a combination of negative abdominal wall pressure in combination with partial mesh reduction seems to be helpful in increasing successful abdominal closure rates3. Aggressive infection control and nutritional support after 72 hours is key. Common to both scenarios is the need for careful, judicious fluid management; organ perfusion must be optimized, but not at the expense of massive bowel and abdominal wall edema. The latter complicates healing and closure4. A final question is whether extubating patients with an open abdomen is safe and feasible. The literature provides a resounding yes to this issue5.

Purpose: Incisional hernias after laparotomy are associated with significant morbidity and increased costs. Recent research on prevention of incisional hernia formation suggests that a laparotomy closure technique using a slowly absorbable monofilament suture with small fascial steps and bites in a continuous, single layer with a suture length to wound length (SL/WL) ratio of at least 4:1 is effective in lowering morbidity. Little is known about application of this evidence in daily practice. Therefore, a survey was performed among Dutch surgeons.Methods: All members of the Dutch Surgical Society were invited to participate in a 24-question online survey on techniques and materials used for abdominal wall closure after midline laparotomy. Subgroup analysis was performed based on surgical subspecialty, type of hospital and experience.Results: Response rate was 26% (402 respondents), representing 97% of all Dutch surgical departments. More than 90% of participants closed the abdominal wall in a single mass layer, using a slowly absorbable monofilament running suture The SL/WL ratio of > 4:1 is practiced by only 35% of participants and preferred suture size was variable among participants. Risk factors for incisional hernia development were generally identified correctly but more than half of the participants were unaware of the incidence and time of occurrence of incisional hernia. Subgroup analysis found that gastrointestinal and oncologic surgeons preferred smaller diameter sutures and higher suture-length to wound-length ratios. Trauma, vascular and pediatric surgeons had lower estimates of incidence of incisional hernia than other subspecialties. Surgeons employed in academic hospitals were more likely to use small fascial steps and smaller suture sizes than their colleagues in non-academic hospitals. Correct estimates of incisional hernia incidence decreased when surgeons perform less than 10 laparotomies annually.Conclusion: Implementation of the latest evidence regarding closure techniques of the abdominal wall is not widespread. Only 35% of surgeons close the abdominal fascia using a suture length to wound length ratio of 4:1, which is recommended based on the latest evidence. Surgical trainees, gastrointestinal and oncological surgeons are most familiar with the recommended technique and use it in their daily practice. Efforts should be directed at improving spreading of this technique.

PurposeInguinodynia or chronic post-herniorrhaphy pain, defined as pain lasting longer than 3 months after open inguinal hernia repair, has become the most important complication after inguinal surgery and therefore compromises the patient´s quality of life. A major reason for inguinodynia might be the lack of neuroanatomical knowledge and suboptimal “management” of the nerves during surgery.MethodsWe present a detailed neuroanatomic mapping of the inguinal region by dissection including the most important surgical landmarks with all nerves confirmed by immunohistochemistry, ultrasound guided visualization of the iliohypogastric, ilio-inguinal, and genital branch of the genitofemoral nerve, and a practical (preoperative) algorithm for clinical management.ResultsSurgically and ultrasonographically relevant structures (“landmarks”) in open hernia repair are the anterior–superior iliac spine, pubic tubercle, Camper´s fascia (superficial layer of the superficial abdominal fascia), External oblique aponeurosis, Internal oblique muscle, Transversus abdominis muscle, superficial inguinal ring, external spermatic fascia, cremasteric fascia with cremaster muscle fibers, internal spermatic fascia, cremasteric vein (=external spermatic vein = “blue line”), ductus deferens, pampiniform plexus, inguinal ligament and the inferior epigastric vessels.ConclusionA detailed understanding of inguinal anatomy is an indispensable basic requirement for all surgeons to perform inguinal ultrasonography as well as open inguinal hernia repair, avoiding complications, especially postoperative inguinodynia.

Open abdomen indicates the abdominal fascia is unclosed to abbreviate surgery and to reduce physiological stress. However, complications and difficulties in patient care are often encountered after operation. During May 2008 to March 2013, we performed a prospective protocol-directed observation study regarding open abdomen use in trauma patients. Bogota bag is the temporary abdomen closure initially but negative pressure dressing is used later. A goal-directed ICU care is applied and primary fascial closure is the primary endpoint. There were 242 patients received laparotomy after torso trauma and 84 (34.7%) had open abdomen. Twenty patients soon died within one day and were excluded. Among the included 64 patients, there were 49 (76.6%) males and the mean Injury Severity Score was 31.7. Uncontrolled bleeding was the major indication for open abdomen (64.1%) and the average duration of open abdomen was about 4.2 ± 2.2 days. After treatment, 53(82.8%) had primary fascia closure, which is significant for patient survival (odds ratio 21.6; 95% confidence interval: 3.27–142, p = 0.0014). Factors related to failed primary fascia closure are profound shock during operation, high Sequential Organ Failure Assessment Score in ICU and inadequate urine amount at first 48 hours admission.

Incisional hernias to the subxiphoid region are rare and anatomically challenging, with bony and cartilaginous structures attaching, as well as conflating abdominal fascia. The repair of hernias in this region is, therefore, difficult and prone to recurrence. The surgical treatment can be done by open or laparoscopic repair but very little is known about which method is superior. We, therefore, reviewed our data of patients undergoing repair of subxiphoid hernias. Between January 2010 and June 2015 twenty-eight patients were treated by laparoscopic (n = 8) or open (n = 20) hernia repair due to an incisional hernia in the subxiphoid region. Patients with ventral hernias with an origin more distal than the M1-area only extending into the subxiphoid region and those undergoing suture hernia repair were excluded. The hernia sizes, in terms of length, width and EHS classification, did not vary between open and laparoscopic repair. The duration of laparoscopic surgery was significantly shorter than the mean operative time for an open subxiphoid hernia repair (168.1 min vs. 96.1 min, respectively; p = 0.012). The groups did not differ significantly in terms of overall postoperative complications (p = 0.568) but the grade (Clavien–Dindo) of complications was higher following open repair leading to three reoperations. Within the follow-up time, we diagnosed significantly (p = 0.031) more subxiphoid hernia recurrences after laparoscopic repair (37.5%, n = 3) than after open repair (0%). Laparoscopic and open repair of subxiphoid incisional hernias are both technically challenging compared to other midline hernias. Referring to our results laparoscopic repair has shorter operative times, lower postoperative morbidity with a higher recurrence rate compared to open repair but the sample size is too small for an overall conclusion.

Purpose: The objective of this study was to demonstrate a new suturing technique in reference to fascia closure after laparotomy in an experimental setup to increase the tearing force of the fascia. Methods: Two ordinary DIN A4 papers, which represents the fascia were sutured at the edges in a length of approx. 5 cm with the known continuous technique in the abdominal surgery and with the new technique, we called it: Spider suture. A bucket arranged on the interconnection was filled with sand until the sutures teared. Measuring the final weight of the bucket allowed comparing the carrying capacities of the paper of the two techniques. Results: A significant (Fisher’s test, p=0.017) increase of mean carrying capacity from 1776.5g (classic continuous suture) to 5101.75g (basic Spider suture) was found. The carrying capacity of the paper was increased to 287% compared to the classic continuous suture. Conclusion: Spider suture could be an effective improvement in closure of the abdominal wall in abdominal surgery to minimize the risk of developing of incisional hernia. This method allows the surgeon to perform an abdominal closure adapted to the quality of patient’s fascia. Further clinical studies will show the effectiveness of this method.&nbsp

BackgroundTemporary abdominal closure (TAC) is increasingly common after military and civilian major trauma. Primary fascial closure cannot be achieved after TAC in 30 per cent of civilian patients; subsequent abdominal wall reconstruction carries significant morbidity. This retrospective review aimed to determine this morbidity in a UK military cohort.MethodsA prospectively maintained database of all injured personnel from the Iraq and Afghanistan conflicts was searched from 1 January 2003 to 31 December 2014 for all patients who had undergone laparotomy in a deployed military medical treatment facility. This database, the patients' hospital notes and their primary care records were searched.ResultsLaparotomy was performed in a total of 155 patients who survived to be repatriated to the UK; records were available for 150 of these patients. Seventy-seven patients (51·3 per cent) had fascial closure at first laparotomy, and 73 (48·7 per cent) had a period of TAC. Of the 73 who had TAC, two died before closure and two had significant abdominal wall loss from blast injury and were excluded from analysis. Of the 69 remaining patients, 65 (94 per cent) were able to undergo delayed primary fascial closure. The median duration of follow-up from injury was 1257 (range 1–4677) days for the whole cohort. Nine (12 per cent) of the 73 patients who underwent TAC subsequently developed an incisional hernia, compared with ten (13 per cent) of the 77 patients whose abdomen was closed at the primary laparotomy (P = 1·000).ConclusionRates of delayed primary closure of abdominal fascia after temporary abdominal closure appear high. Subsequent rates of incisional hernia formation were similar in patients undergoing delayed primary closure and those who had closure at the primary laparotomy.

Any deformities or absence of the umbilicus is immediately recognizable. Many techniques have been described for achieving aesthetic repositioning. The authors describe the inverted-V chevron umbilicoplasty procedure and its outcome. The discontinuous incision design prevents circumferential scar contraction. The inverted-V chevron inset achieves an arrowhead-shaped design of the original umbilicus that encourages natural retrusion, inferior slope, and a cranial fold. It creates the appearance of a small umbilicus with an appropriate opening that other incisions fail to recreate. To avoid tethering sensation seen when the umbilicus is sutured to the abdominal fascia, we suture to Scarpa’s fascia to allow mobility of the umbilical stalk while still achieving a natural contour. Removal of fat from the surrounding abdominal area creates depth by accommodating the horizontal dimension of the umbilicus, hiding the scar toward the base.

The open abdomen is an increasingly used technique that is applied in a wide variety of clinical situations. The ABThera Open Abdomen Negative Pressure Therapy System is one of the most common and successful temporary closure systems, but it has limited ability to close the fascia in approximately 30% of patients. The abdominal reapproximation anchor system (ABRA) is a dynamic closure system that seems ideal to manage patients who may not achieve primary fascial closure with ABThera alone. We report on the use of the ABRA in conjunction with the ABThera in patients with an open abdomen.We retrospectively analyzed patients with an open abdomen managed with the ABThera and ABRA between January 2007 and December 2012 at the Halifax Infirmary, QEII Health Science Centre, Halifax, Nova Scotia.Sixteen patients had combination therapy using the ABRA and ABThera systems for treatment of the open abdomen. After removing patients who died prior to closure, primary fascial closure was achieved in 12 of 13 patients (92%).We observed a high rate of primary fascial closure in patients with an open abdomen managed with the ABThera system in conjuction with the ABRA. Applying mechanical traction in addition to the ABThera should be considered in patients predicted to be at high risk for failure to achieve primary fascial closure.La laparotomie, ou « abdomen ouvert », est une technique de plus en plus employée dans une grande diversité de contextes cliniques. Le système ABThera (thérapie par pression négative pour abdomen ouvert) est l’un des systèmes de fermeture temporaire de l’abdomen les plus fréquemment utilisés et efficaces, mais sa capacité de refermer le fascia apparaît limitée chez environ 30 % des patients. Le système ABRA est un système de fermeture dynamique qui semble idéal pour la prise en charge des patients qui pourraient ne pas obtenir une fermeture primaire du fascia avec le système ABThera seul. Nous faisons rapport de l’utilisation du système ABRA en conjonction avec le système ABThera chez des patients soumis à une laparotomie.Nous avons analysé rétrospectivement des patients soumis à une laparotomie et pris en charge au moyen des systèmes ABThera et ABRA entre janvier 2007 et décembre 2012 au Halifax Infirmary du Centre des sciences de la santé QEII d’Halifax, en Nouvelle-Écosse.Seize patients ont subi un traitement concomitant par les systèmes ABRA et ABThera pour leur laparotomie. Après exclusion des patients décédés avant l’obtention de la fermeture primaire du fascia, cette dernière a été réussie chez 12 patients sur 13 (92 %).Nous avons observé un taux élevé de fermeture primaire du fascia chez les patients soumis à une laparotomie et traités au moyen du système ABThera en conjonction avec le système ABRA. L’application d’une traction mécanique en plus du système ABThera est à envisager chez les patients présumés à risque élevé d’échec de la fermeture primaire du fascia.

Pedicled transverse rectus abdominis myocutaneous (TRAM) breast reconstruction is associated with increased abdominal wall morbidity. We present a method of abdominal wall reconstruction using an adjunct technique to validated procedures of hernia repair. This study is a retrospective, single-surgeon analysis of 21 patients between 2005 and 2012. Patients had bony suture anchoring of synthetic polypropylene mesh to the anterior superior iliac spine bilaterally and the pubic symphysis after the abdominal fascia was reconstructed. Patient mean follow-up was 62 months. Of the series, five patients underwent bilateral pedicled TRAM breast reconstruction. None of the 21 patients developed abdominal wall hernias. One patient developed postoperative bulging, which was retreated successfully. Two patients developed mesh infections; none required radical removal of mesh. There were no flap failures or loss in the series. The BARS technique for abdominal wall reconstruction provides excellent reinforcement of abdominal reconstruction in conjunction with pedicled TRAM breast reconstruction. Level of Evidence: Level IV, therapeutic study.

Up to the present, the optimal time to close an open abdomen remains controversial. This study was designed to evaluate whether early fascial abdominal closure had advantages over delayed approach for open abdomen populations. Medline, Embase, and Cochrane Library were searched until April 2013. Search terms included “open abdomen,” “abdominal compartment syndrome,” “laparostomy,” “celiotomy,” “abdominal closure,” “primary,” “delayed,” “permanent,” “fascial closure,” and “definitive closure.” Open abdomen was defined as “fail to close abdominal fascia after a laparotomy.” Mortality, complications, and length of stay were compared between early and delayed fascial closure. In total, 3125 patients were included for final analysis, and 1942 (62%) patients successfully achieved early fascial closure. Vacuum assisted fascial closure had no impact on pooled fascial closure rate. Compared with delayed abdominal closure, early fascial closure significantly reduced mortality (12.3% versus 24.8%, RR, 0.53,P<0.0001) and complication incidence (RR, 0.68,P<0.0001). The mean interval from open abdomen to definitive closure ranged from 2.2 to 14.6 days in early fascial closure groups, but from 32.5 to 300 days in delayed closure groups. This study confirmed clinical advantages of early fascial closure over delayed approach in treatment of patients with open abdomen.

BACKGROUND: Wounds and their management are fundamental to the practice of surgery.Surgical wound dehiscence after laparotomy remains a serious complication.To evaluate the effect of prophylactic retention sutures in patients with a high risk for wound dehiscence who underwent midline laparotomy. Patients and methods:One hundred fifty(150) cases were randomized to form two groups with 75 patients each: a prophylactic group by using retention sutures and an non prophylactic group. A central randomization for both hospitals was performed. Two patients in the non prophylactic group and three patients in the prophylactic group In the non prophylactic(control) groupStandard midline incision and continuous mass closure technique was used in each case using a running looped 1/0 nylon string located 1 cm from the edge of the lineaalba.In the prophylactic group, the fascia was sutured using the same technique as the non prophylactic group; however, retention sutures were added using a 1/0 nylon string every 10 cm and contained 5 cm of the skin, subcutaneous tissue, rectus muscle, and abdominal fascia (except peritoneum) on each side. All fascia closures were performed by tow attending surgeons who adhered strictly to the protocol.Occurrence of abdominal dehiscence was assesseddaily by precise examination of the wound. Results:The incidence of abdominal wound dehiscence was 3 patients (4%) in the prophylactic group and 10 patients (13.3%) in the control (nonprophylactic )group (P = 0.007 ) therefore it is significantConclusion:Ourconclsion that prophylactic retention sutures can decrease the incidence of abdominal wound dehiscence but although there is decrease incidence of post operative evisceration ,wound infection and post operative pain , there was no significant difference.

Background: Laparotomy is a major surgical procedure in emergency settings. There is paucity of data regarding abdominal fascia closure in emergency laparotomies in Indian population. This study was planned to compare two techniques of fascial closure namely continuous and interrupted using polydioxanone in patients undergoing midline emergency laparotomies in our institute.Methods: This prospective study was conducted in Surgery Department, MMC&H, Muzaffarnagar, from January 2017 to June 2018. 60 patients undergoing emergency laparotomies were divided into two groups of 30 each. Group I (study group) patients underwent interrupted suture abdominal closure; Group II (control group) patients underwent continuous suture closure.Results: Commonest diagnoses were duodenal and enteric perforations. Mean closure time in Group 1 was 31.6 minutes and in Group 2 -17.3 minutes. Mean hospital stay in Group I and II were 12.88 and13.76 days respectively. 4 Group I patients developed wound discharge versus 6 patients in Group II. Burst abdomen occurred in 3 out of 60 patients. One Group I patient had localised fascial burst. One Group II patient had localized while one had complete fascial burst. One incisional hernia was observed in each group at 3rd month of follow up. Three patients in Group 1 and one in Group 2 developed suture sinus.Conclusions: Major complication is wound dehiscence leading to increased morbidity, hospital stay and cost. In our study, we used continuous and interrupted PDS sutures and found that interrupted suturing method of abdominal wall closure is better, though it takes more time.

Purpose Combined heart and liver transplantation is a live saving procedure for patients with advanced dual organ failure. Although described 35 years ago, less than 20 cases are performed every year, reflecting the complexity of the procedure. We present the first case series of adult patients receiving En-Bloc Heart-Liver Transplant (En-Bloc HLTx). Methods A present a retrospective analysis of our experience with En-Bloc HLTx in five adult patients, including demographic characteristics, indications, surgical course with operative data, surgica outcomes, and long term follow up with evaluation of rejection by myocardial biopsy results. Results Five patients received En-Block HLTx between June 2016 and December 2017. Mean recipient age was 43 years (26-63), and 3 (60%)patients were male.Indication for dual organ transplantation included hereditary ATTR amyloidosis (n=1), gestations cardiomyopathy with cardiac cirrhosis (n=2), and idiomatic dilated cardiomyopathy with cryptogenic cirrhosis (n=1) or coexistent NASH (n=1).All patients presented NYHA FC IV symptoms, and 4 were admitted to the hospital awaiting transplantation for 63 days (51-89) as status 1A, while 1 patient was on home inotropic support. Sodium MELD score ranged from 8 to 28 (mean = 17.6). Total operative time was 430 min (393-480), and ischemic times (IT) were equal for both organs, with cold IT of 85 min (32-136), and warm IT of 37.5 min (31-47). Patients required CPB support for 107 min (80-138), and aortic cross-clamp of 58 min (52-72). Abdominal fascia remained open in 4 patients, and sternum in 3 patients, with planned definitive wound closure within 48 hours in all patients. Thirty day operative survival was 100%, and 4 (80%) patients were discharged alive from the hospital on POD 36 (17-67). One patient expired on POD 55, due to fungemia and multi system organ failure. Mayor postoperative complications included prolonged ventilation requiring tracheostomy on 3 patients, and renal insufficiency requiring dialysis in 2 patients. Follow up was complete all 4 patients for up to 18 months, All patients remained on low immunosuppression regimen, and there was no evidence of grade 2 or higher rejection on anyone. Conclusion En-Bloc HL Tx is a safe procedure for patients requiring dual organ transplantation. Operative times are significantly decreased, and mid-term outcomes are comparable to single organ transplantation.

Background The optimal management of hemodynamically stable asymptomatic patients with anterior abdominal stab wounds (AASWs) remains controversial. The goal is to identify and treat injuries in a safe cost-effective manner. Common evaluation strategies are local wound exploration (LWE), diagnostic peritoneal lavage (DPL), serial clinical assessment (SCAs) and computed tomography (CT) imaging. Making a decision about the right time to operate on a patient with a penetrating abdominal stab wound, especially those who have visceral evisceration, is a continuing challenge. Objectives Until the year 2010, our strategy was emergency laparotomy in patients with penetrating anterior fascia and those with visceral evisceration. This survey was conducted towards evaluating the results of emergency laparotomy. So, better management can be done in patients with penetrating abdominal stab wounds. Patients and Methods This retrospective cross-sectional study was performed on patients with abdominal penetrating trauma who referred to Al- Zahra hospital in Isfahan, Iran from October 2000 to October 2010. It should be noted that patients with abdominal blunt trauma, patients under 14 years old, those with lateral abdomen penetrating trauma and patients who had unstable hemodynamic status were excluded from the study. Medical records of patients were reviewed and demographic and clinical data were collected for all patients including: age, sex, mechanism of trauma and the results of LWE and laparotomy. Data were analyzed with PASW v.20 software. All data were expressed as mean ± SD. The distribution of nominal variables was compared using the Chi-squared test. Also diagnostic index for LWE were calculated. A two-sided P value less than 0.05 was considered to be statistically significant. Results During the 10 year period of the study, 1100 consecutive patients with stab wounds were admitted to Al-Zahra hospital Isfahan, Iran. In total, about 150 cases had penetrating traumas in the anterior abdomen area. Sixty-three (42%) patients were operated immediately due to shock, visceral evisceration or aspiration of blood via a nasogastric tube on admission. Organ injury was seen in 78% of patients with visceral evisceration. Among these 87 cases, 29 patients’ (33.3%) anterior fascia was not penetrated in LWE. So, they were observed for several hours and discharged from the hospital without surgery. While for the remaining 58 patients (66.6%), whose LWE detected penetration of anterior abdominal fascia, laparotomy was performed which showed visceral injuries in 11 (18%) cases. Conclusions All in all, 82 percent of laparotomies in patients with penetrated anterior abdominal fascia without visceral evisceration, who had no signs of peritoneal irritation, were negative. So, we recommended further evaluation in these patients. However, visceral evisceration is an indication for exploratory laparotomy, since in our study; the majority of patients had organ damages.

Background: Abdominal wound dehiscence (WD) is a postoperative complication with high mortality and morbidity rates. Retention sutures are often used in surgical take-back for dehiscence. The aim of this study was to assess the reduced rate of dehiscence in midline laparotomy using prophylactic retention sutures in high-risk patients. Materials and methods: Three hundred high-risk patients with at least two risk factors for dehiscence who underwent midline laparotomy between 2008 and 2010 were randomly divided into two groups. In the control group, the fascia was continuously repaired using a running looped #1 nylon suture. For the intervention group, we added retention sutures that included the skin, subcutaneous tissue, rectus muscle, and abdominal fascia. We compared the rates of WD, evisceration, wound infection, postoperative pain, postdehiscence mortality, and late incisional hernia for these two groups. Results: After accounting for early mortalities, 147 patients were followed in the intervention group and 148 patients in the control group. WD occurred in 6 patients (4%) in the intervention group and 20 control patients (13.3%) (P ¼ 0.007). Abdominal evisceration after surgery occurred in 1 patient (0.7%) with retention sutures and 4 control patients (2.7%) (P ¼ 0.371). There was no significant difference in wound infection and incisional hernia between the two groups. Postoperative pain scores between the two groups did not differ significantly during the first 3 d, but did differ on the fourth day. Conclusion: Prophylactic retention sutures reduce the occurrence of WD following midline laparotomy in high-risk patients with multiple risk factors for impaired wound healing without imposing remarkable postoperative complications.

With the progressive use of new diagnostic techniques, the management of penetrating abdominal stab wounds is changing. Most studies have been conducted in well-equipped trauma centers in developed countries, and there is a paucity of reports from general teaching hospitals with limited resources. We reviewed the assessment of anterior abdominal stab wounds in patients presenting to our hospital hoping to establish an evidence-based algorithm for managing such patients in busy general hospitals. The medical records of all 393 patients treated at our hospital for anterior abdominal stab wounds over a 7-year period were reviewed. Information regarding age, gender, site of the stab wound, management, and complications were analyzed. Twenty-six patients with hemodynamic instability at presentation underwent urgent laparotomy (LAP); 24 (92.3 %) of those procedures were therapeutic. Local wound exploration (LWE) proved that 114 (31 %) of all hemodynamically stable patients had no abdominal fascia penetration and consequently could be discharged home from the emergency department (ED). A total of 253 patients were found to have fascial penetration, and all were admitted for repeat clinical assessments (RCA) and imaging studies. A total of 121 (48 %) of the patients underwent abdominal exploration with 102 (84 %) therapeutic LAP procedures. Hemodynamic instability and evisceration should continue to prompt urgent LAP. For stable patients, a sequence of LWE followed by focused abdominal sonography for trauma and computed tomography scanning for unclear cases primed by RCA was found to be efficient in limiting hospital admissions and reducing the rate of non-therapeutic LAP.

Background: Incisional hernia (IH) is a well-known complication after abdominal surgical procedures. The exact etiology of IH is still unknown even though many risk factors have been suggested. The aim of this study was to create an animal model of a weakly healed abdominal fascia that could be used to evaluate the actively healing fascia. Such an animal model may promote future research in the prevention of IH. Methods: 86 male Sprague-Dawley rats were used to establish a model involving six experiments (experiments A-F). Mechanical testing of the breaking strength of the healed fascia was performed by testing tissue strips from the healed fascia versus the unincised control fascia 7 and 28 days postoperatively. Results: During the six experiments a healing model was created that produced significantly weaker coherent fascia when compared with the control tissue measured in terms of mechanical breaking strength. This new animal model employed myofascial closing after a full thickness abdominal incision using a running suture with fast-absorbable suture material. This technique produced a weak myofascial layer compared with the control tissue measured in terms of breaking strength after both 7 and 28 days. Conclusion: It was possible to create a healed but weak abdominal fascia in rats with a minimum of defects after incision using a running suture technique in the fascia. In contrast to other models, regular tissue defects were absent, and the model can therefore be used to evaluate the changes, both histological and mechanical, in the actively healing fascia, which may lead to incisional herniation. Furthermore, the model may also be used to study interventions performed to promote healing. This contrasts with existing models with regular fascia defects, which are not well suited for this purpose.

Surgical mesh is being used for healing hernia, pelvic organ prolapse, skull injuries and urinary incontinence. In this research the effect of fabric structure on the mechanical properties of warp knitted surgical meshes in comparison to abdominal fascia has been investigated. For this purpose, warp knitted surgical mesh with five different structures (Tricot, Pin-hole-net, quasi-Sandfly, Sandfly and quasi-Marquissite) were produced using polypropylene monofilament. Thereafter, their mechanical properties such as uniaxial tensile behavior in various directions (wale-wise (90°), course-wise (0°) and diagonal (45°)), bending resistance and crease recovery were analyzed. The meshes demonstrated different elastic modulus in various directions, which can be attributed to the pore shape (pore angle) and underlap angle in the structure of mesh. Except Pin-hole-net mesh, other produced meshes exhibited better level of orthotropy in comparison to abdominal fascia. The most flexible mesh in both wale-wise and course-wise directions was quasi-Sandfly and thereafter quasi-Marquissite. Tricot and Pin-hole-net manifested the highest crease recovery in wale-wise and coursewise directions respectively. The most desirable mesh in terms of porosity was quasi-Marquissite mesh. Overall, the quasi-Marquissite mesh was selected as the most suitable surgical mesh considering all advantages and disadvantages of each produced mesh in this study.

Background Reconstruction of complex pharyngoesophageal defects presents a major challenge, particularly in soft tissue deficient and previously scarred surgical sites. In recent years, the free jejunum flap method has emerged as a reliable means of esophageal reconstruction. However, it may require cutaneous coverage with an additional flap in extensively scarred, secondary reconstructions. Prefabrication of an intestinal/cutaneous composite flap can potentially solve this problem. Materials and Methods Total 28 Sprague Dawley rats were used in the study protocol. A vascularized jejunal segment was transposed beneath the deep inferior epigastric perforator (DIEP) flap. Contact with underlying abdominal fascia was prevented using a silicone sheet. Animals were distributed into five groups based on the timing of deep inferior epigastric vessel ligation to determine the time required for successful revascularization. The viability and the vascular anatomy of the prefabricated structures were analyzed using histology and microangiography. Results A jejunum/DIEP composite flap was successfully prefabricated based on mesenteric vessels. The skin component survived intact after 5 days of contact with serosal surface of the jejunal segment. Conclusion The clinical application of this technique can provide an alternative means of single-stage esophageal reconstruction, especially in patients with soft tissue deficiency and donor vessel unavailability.

Nipro-Toyobo-paracorporeal pulsatile flow VAD (Nipro VAD; Nipro, Osaka, Japan) has been used most commonly as a paracorporeal VAD (p-VAD) in Japan. There are few reports describing clinical course of post LVAD explantation and its complication. We herein present two cases of apical abscess after the explantation of the device. SSI is a main risk factor of formation of the apical abscess at the time of LVAD explantation. It is mandatory to perform sufficient debridement and closure of the layers including abdominal muscle and anterior abdominal fascia at exit sites in the explantation surgery. Omentopexy is also helpful for prevention from infection. Routine removal of apical cuff and outflow graft could be considered as one of the options when LVAD is explanted as bridge to recovery.

Abdominal wall defects are some of the most commonly encountered reconstructive challenges. Goals of abdominal wall reconstruction include providing stable soft-tissue coverage, restoring fascial integrity, preventing hernia, protecting abdominal viscera, and restoring function. Deficiency in the skin/subcutaneous tissue can be repaired by a variety of methods: (1) primary closure if there is minimal tension between the wound edges, (2) rearrangement of existing tissue such as skin grafts, local flaps, regional flaps, and free flaps and (3) expanding the existing tissue with tissue expansion. First described in 1989 for congenital defects of the lower abdominal wall, tissue expansion remains a powerful tool to increase the amount of abdominal skin and subcutaneous tissue with subsequent skin flaps closure without tension. It involves insertion of a silicone balloon under the skin and subcutaneous tissue. The balloon is serially inflated by gradual injection of sterile saline via a remote or integrated port to inflate the skin and subcutaneous tissues over the expander. This can provide well-vascularized, autologous skin, subcutaneous tissue, and abdominal fascia for the repair of large defects. Tissue expansion can be a valuable tool in the spectrum of abdominal wall reconstruction.

The inability to close the abdominal fascia after a complex procedure or the treatment of abdominal compartment syndrome results in open abdomen. If, after surgical intervention, the abdomen cannot be closed primarily, it is imperative to perform a temporary abdominal closure (TAC) to protect the intestines, prevent fluid losses, and prevent other complications. The TAC can be either an improvised or commercial device that serves to protect the bowel and collect effluent from the abdomen. The ICU provider must have knowledge of the TAC device and be able to evaluate and respond to issues in the ICU surrounding the device including placement or changing one in the intensive care unit. This article describes the TAC and the steps involved in the initial placement, removal, and replacement of the device in the ICU setting as well as troubleshooting the device.

The use of the "open abdomen" as a technique in the management of the complex surgical patient stems from the concept of damage control. Damage control principles underscore the importance of an abbreviated laparotomy focused on control of hemorrhage and gastrointestinal contamination in patients presenting with significant physiologic compromise. Definitive repair of injuries is postponed and the abdomen is temporarily "closed" using one of a number of different techniques. The ultimate goal is formal abdominal fascial closure within 48-72 hours of the initial laparotomy. Frequently, daily trips to the operating room are required for incremental closure of the abdominal fascia. However, in some cases, fascial closure is not possible secondary to ongoing visceral edema and loss of the peritoneal domain. In these cases, the patient is left with an "open abdomen" until skin grafting over the exposed peritoneal organs can be performed. Patients with an open abdomen have peritoneal contents exposed to the atmosphere and require a complex dressing to maintain fascial domain and provide protection to exposed organs. These patients are typically critically ill and managed in the intensive care unit early in the disease process. The open abdomen has become an important tool for the management of physiologically unstable patients requiring emergent abdominal surgical procedures. These patients present unique challenges to the critical care and nutrition support teams. Careful attention to fluid and electrolyte management, meticulous wound care, prevention of enteroatmospheric fistula, and individualized nutrition support therapy are essential to successful recovery in this patient population.

This report emphasizes the importance of performing meticulous closure on all trocar sites 10-mm and greater., Background: Nonbladed trocars are considered less traumatic to the abdominal wall due to the lack of fascial incision. It has been suggested that closure of the abdominal fascia may be unnecessary when such nonbladed trocars are used. Case Report: We report on 2 patients who were diagnosed with trocar-site hernias 2 days after laparoscopic appendectomy performed using 11-mm nonbladed trocars. Conclusion: Although rare, trocar-site hernias after laparoscopic surgery with nonbladed trocars remain a cause of postoperative morbidity and require prompt intervention. Therefore, this report underscores the significance of performing meticulous closure of all trocar sites that are ≥10mm.

The use of mammalian target of rapamycin inhibitors coincides with an increased incidence of surgical complications. In previous experiments, serious negative effects of postoperative everolimus on anastomotic strength were found. This study aims to investigate if delayed drug administration can prevent loss of wound strength. Ten groups of Wistar rats each received daily oral doses of 1.0 or 2.0 mg/kg everolimus, starting the day of anastomotic construction in both ileum and colon, or 1, 2, 3, or 4 days later. The 11th group received saline. Seven days later, wound strength in anastomoses and in the abdominal wall and wound hydroxyproline levels were measured. Mean wound strength was significantly and dose-dependently reduced if everolimus was started on the day of operation. In ileum and colon, strength was not affected if drug administration was delayed until the third or second day, respectively. In abdominal fascia, this was the case only if everolimus was withheld until day 4. In general, changes in wound hydroxyproline content showed similarities to changes in wound strength. Thus, delaying administration of everolimus for 2-4 days after operation can prevent a serious loss of wound strength, both in the intestine and in the abdominal fascia.

Incisional hernia is a frequent complication of abdominal surgery (incidence 2–20%). Diagnosis by physical examination is sometimes difficult, especially in small incisional hernias or in obese patients. The additional diagnostic value of standardized ultrasonography was evaluated in this prospective study. A total of 456 patients participating in a randomized trial comparing two suture materials for closure of the abdominal fascia underwent physical examination and ultrasonography at 6-month intervals. Wound complaints and treatment of incisional hernia were also noted. Statistical analysis was performed using the Chi-squared and Fisher’s exact tests (SPSS). Interest variability analysis was performed. During a median follow-up of 31 months, 103 incisional hernias were found. A total of 82 incisional hernias were found by physical examination and an additional 21 with ultrasonography. Six of these additional hernias were symptomatic and only one of the additional hernias received operative treatment. The false-negative rates for physical examination and ultrasonography were 25.3 and 24.4%, respectively. Interest variability was low, with a Kappa of 0.697 (P

The authors describe a technique that allows suture of the abdominal fascia at sites using a transcurtaneous approach and standard surgical instruments., Background and Objectives: Fascial closure of port sites represents a challenging issue in laparoscopic surgery. The aim of this article is to introduce a procedure that allows the safe suturing of the abdominal fascia in these wounds. Methods: We herein describe a simple technique for fascial closure after laparoscopy using a transcutaneous approach and standard surgical instruments for suture. Results: The method was used in 34 patients with no intraoperative incidents and no port-site hernias during a mean follow-up of 23.9 months (median 20.5, range 5 to 47). Conclusion: The procedure is easy to perform, safe, fast, and inexpensive.

A common problem in patients with chronic liver diseases and liver cirrhosis is the development of ascites. First line therapy for ascites is the restriction of sodium intake and a diuretic treatment. Paracentesis is indicated in patients with large compromising volumes of ascites. In selected cases, permanent drainage of ascites over prolonged periods of time may be indicated. In the case presented here, a 66-year-old male patient, who was hospitalized with liver cirrhosis caused by alcoholic abuse, required permanent drainage of ascites. After three weeks of continuous ascites drainage, he developed bacterial peritonitis. Conventional attempts to remove the catheter by transcutaneous pulling failed and we thus decided to perform a median laparotomy to remove the catheter surgically. Intraoperatively an adhesion of the ascites drain (a so called ‘basket catheter’) to the mesentery very close to the small intestine was found, approximately 50 mm distal of the ligament suspensorium duodeni (ligament of Treitz). The basket catheter used for this patient was especially designed to drain infections, not fluids. We solved the adhesion, removed the basket catheter, placed a new surgical drain and finished the operation. The patient developed a rupture of his abdominal fascia suture 12 days later, which was caused by massive ascites and complicated by hepatorenal syndrome type I. The patient was taken to the operating theater again. After the second operation, the chronic liver failure decompensated and the patient died. Ascites caused by liver cirrhosis is still a medical challenge. The indication for the use of the correct percutaneous catheter for permanent paracentesis should be carefully considered. Some catheters are obviously not suited to drain ascites and may lead to fatal outcomes.

A 37-year-old man involved in a motor vehicle accident was admitted to our hospital with disturbed consciousness. Computed tomography (CT) showed an acute, right-sided epidural hematoma and pneumocephalus. Emergency evacuation of the acute epidural hematoma was carried out, and his condition gradually recovered. However, cerebrospinal fluid (CSF) rhinorrhea continued despite conservative treatment. Three-dimensional reconstructed CT revealed a bone defect, which was approximately 20 mm in size, in the planum sphenoidale and tuberculum sellae, and magnetic resonance imaging demonstrated a traumatic meningo-encephalocele through the defect, with CSF collection in the sphenoid sinus. Endoscopic endonasal transsphenoidal surgery was performed. The 9-mm diameter dural defect was clearly visualized in the sphenoid sinus and was reconstructed with a combination of suturing and overlay with abdominal fascia, and absorbable polyglycolic acid felt. The CSF leakage from a traumatic meningo-encephalocele through the planum sphenoidale was successfully repaired by endoscopic endonasal surgery. Thorough preoperative evaluation of the feasibilities of the endoscopic and transcranial approaches should be based on the preoperative identification of the fistula, the bone defect, and vital structures.

Before using rtPA clinically, its effects on healing of bowel anastomoses and laparotomy wounds should be investigated. METHODS: Peritonitis was induced in 148 male Wistar rats via intra-abdominal injection of a feces/bacteria mixture. Laparotomy, operative debridement and construction of a colo-colostomy after a limited colectomy or ileo-ileostomy after a limited ileal resection were performed after 1 hour. All animals received antibiotics (ceftriaxone plus metronidazole). In addition to untreated controls, other animals received rtPA in 1 of 3 dosing schemes, starting immediately after operation or 24 hour afterwards. Wound strength and hydroxyproline content of the wound were analyzed after 3 or 7 days. RESULTS: Mortality was 2% and manifestations of excessive bleeding were virtually absent. RtPA significantly decreased the rate of abscess formation. Neither bursting pressure nor breaking strength of the anastomoses was affected by any of the rtPA protocols. The same was true for wound strength in the abdominal fascia. Additionally, wound hydroxyproline content and architecture remained unchanged after rtPA administration. CONCLUSION: Intraperitoneal rtPA administration consistently and significantly decreased the rate of abscess formation, but did not affect wound healing. Clinical studies investigating its potential as an adjunct in the treatment of secondary peritonitis may be warranted.

Objective: In patients undergoing midline incisions, the abdominal fascia can be closed with a continuous or interrupted suture using various materials. The aim of this study is to compare: (1) interrupted technique with rapidly absorbable sutures and (2) continuous techniques with different slowly absorbable sutures, focusing on the incidence of incisional hernias within 1 year. of Background Data: A meta-analysis suggested that the incidence of incisional hernias can be more effectively reduced with slowly absorbable continuous sutures. Methods: Multicenter randomized surgical trial with 3 parallel groups. Patients were scheduled for primary elective midline incisions. All surgeons were trained (4:1 suture wound length in continuous groups) and monitored. Primary end point, measured within 1 year after surgery, was the frequency of incisional hernias diagnosed by clinical examination and confirmed by ultrasound. Complications and safety were used as secondary end points. This study has been registered with the ISRCTN Register (INSECT: ISRCTN24023541). Results: Conducted on 625 randomized patients (210 interrupted Vicryl, 205 continuous polydioxanone suture (PDS), 210 continuous Monoplus), the primary analysis showed an incidence of 28 incisional hernias (15.9%) versus 15 (8.4%) versus 22 (12.5%) for the 3 closure techniques, respectively (P = 0.09). No significant difference was observed between the 3 groups with regard to burst abdomen (4 [2.0%] vs. 6 [3.0%] vs. 8 [4.0%], P = 0.46), wound infection (26 [12.7%] vs. 39 [19.4%] vs. 33 [16.3%], P = 0.19), pulmonary infections (9 [4.4%] vs. 5 [2.5%] vs. 5 [2.5%], P = 0.46), serious adverse events (63 [30.0%] vs. 57 [27.8%] vs. 61 [29.1%], P = 0.89), and 1-year mortality (16 [7.9%] vs. 11 [5.5%] vs. 16 [7.9%], P = 0.54). Conclusions: The incidence of incisional hernias and the frequency of wound infection was higher than expected in all groups. New concepts need to be developed and studied to substantially reduce the frequency of incisional hernias.

Objective The surgical treatment of recurrent coarctation in adults supposes a redo left thoracotomy with adhesions and high risk of bleeding and injury of adjacent nerves. The rate of paraplegia in these cases may reach 2.6%. Extra-anatomic aortic bypass avoids these complications. We present our results with ascending-to-abdominal aorta extra-anatomic bypass for recurrent aortic coarctation in adults. Methods Between September 1979 and November 2006 12 patients underwent ascending-to-abdominal aorta bypass. There were 10 males and 2 females. Mean age was 36.2+/-11.3 (range 21-57) years old. Mean age at primary repair was 14.3+/-4.2 years old (range 8-21). Operative technique consisted of performing an ascending-to-abdominal aorta bypass via median sternotomy extended into the epigastrium with a supra-umbilical laparotomy through the mid-line abdominal fascia. Concomitant procedures were performed in six patients: three isolated aortic valve replacements (AVR), two ascending aorta graft replacements and one AVR associated with coronary artery bypass graft (CABG). Results No postoperative mortality was observed. Mean follow-up time was 10.4+/-9.3 years (range 0.3-27.8). No patients had any graft-related complication or death and all grafts were patent at the end of the follow-up. One patient developed a dilated myocardiopathy, dying at 14 years of follow-up. Four patients had persistence of arterial hypertension controlled with one drug therapy and five patients were asymptomatic. Conclusions Ascending-to-abdominal aorta extra-anatomic bypass is a safe, effective and less invasive technique for aortic recoarctation in adults with good results at long-term.
