Background: The current literature supports the closure of trocar sites ≥10‐mm for the risk of developing incisional hernias, while there is no need to suture the abdominal fascia when using 5‐mm trocars. To date, evidence regarding the closure of 8‐mm trocars that are use by new robotic systems is weak. The aim of our study was to investigate the incidence of incisional hernia for 8‐mm trocars. Methods: We prospectively collected data on all patients undergoing robotic‐assisted abdominal wall surgery from 2020 to 2023, in whom the abdominal fascia of all 8‐mm trocars was not closed. The enrolled patients underwent a follow‐up visit during which we conducted clinical and sonographic evaluations of all 8‐mm trocars, in addition to assessing the satisfaction levels of the patients. The primary outcome was the incidence of port‐site hernia. Results: We enrolled 166 patients, 155 men and 11 women, for a total of 513 trocars accessed. Mean age was 61.1 ± 14.0 years, and mean BMI was 27.0 ± 3.9 kg/m2. The follow‐up visits were carried out after a median follow‐up of 14.5 (9.0–23.2) months. Only one case developed an asymptomatic 1 × 1 cm supra‐umbilical hernia that was not treated. Patient reported a satisfaction regarding the 8‐mm trocars and skin sutures of 9.8 ± 0.5 out of 10 points. Conclusions: The occurrence of a trocar‐site hernia after 8‐mm robotic access is extremely low. Hence, the fascia closure may not be necessary. [ABSTRACT FROM AUTHOR]

Background Abdominal wall morbidity occurs with increased frequency following flap harvest in the obese abdomen. Its impact on patient-reported outcomes (PROs) in breast reconstruction has been poorly characterized. Methods A retrospective review of obese patients undergoing abdominal-based free autologous breast reconstruction was conducted over 15 years. Patient operative characteristics were recorded and outcomes were analyzed. PROs were assessed using the BREAST-Q abdominal survey. Results In total, 75 women (108 flaps) with the mean body mass index (BMI) of 33.2 were included. Flaps included deep inferior epigastric artery perforator (24%), muscle-sparing (43%), and free transverse rectus abdominis myocutaneous flaps (f-TRAM; 33%). World Health Organization (WHO) obesity class, BMI, and flap type did not affect flap failure (1%) or complication rates. Hernia developed in 7%; all necessitated repair. Eight percent developed abdominal bulge; one was repaired. Hernia formation was associated with increased patient age (p < 0.05). Bulge formation occurred more often in f-TRAM donor sites (p = 0.005). BMI, WHO class, flap type, and mesh use were not related to hernia or bulge occurrence in either univariate or multivariate analysis. The survey response rate was 63%. Abdominal Physical Well-Being (proxy for abdominal wall function) and Satisfaction with Abdomen (patient-perceived cosmesis) were similar across flap types, age, and WHO classification groups. Patients with postoperative bulge reported higher abdominal physical well-being scores, regardless of flap type (p < 0.01). Bulge was correlated with lower satisfaction (p < 0.05). Conclusion The incidence of abdominal wall morbidity following abdominal free-tissue transfer for breast reconstruction was acceptably low in our population of obese patients. Hernia was a clinically significant complication, warranting surgical repair. Bulge was primarily a cosmetic concern and did not detract from patient-reported abdominal wall function. Age may represent an independent risk factor for hernia formation in this population. [ABSTRACT FROM AUTHOR]

Background: Because of a weakening in the muscular structure of the wall of the abdomen, an abdominal wall hernia is a protrusion of the abdominal tissues or organs that occurs in the abdominal cavity. Aim: To report our current practice in Mansoura for strangulated inguinal hernia to identify incidence, types, methods of repair and risk factors related to postoperative complications. Patients and methods: This prospective observational research was conducted on 183 patients of irreducible inguinal hernia who presented with irreducible inguinal hernia and they were admitted to Mansoura University Emergency Hospital and Mansoura International Hospital. Results: The mean duration of the surgical procedure was 84.07 minutes. ICU admission was required in only two patients (2.8%), the duration of hospitalization ranged between 3 and 7 days. Regarding postoperative complications, scrotal edema was the most common complication (29.2%). Other early complications included seroma formation (8.3%), paralytic ileus (6.9%), superficial wound infection (5.6%), hematoma (1.4%), and leakage (1.4%). Only one patient had postoperative mortality (1.4%), one patient required hospital readmission (1.4%), and one patient required surgical intervention for peritonitis secondary to leakage from the anastomotic site (1.4%). Recurrence in 6 months postoperative was encountered in eight patients (11.1%) Conclusion: The incidence of strangulation is 39.3% among patients presented with irreducible inguinal hernia. The prevalence of heavy manual work, diabetes mellitus was statistically significantly higher in the irreducible strangulated cases. No significant differences were detected between the mesh and anatomical repairs groups regarding postoperative complications. [ABSTRACT FROM AUTHOR]

Surgeons use several quality-of-life instruments to track outcomes following abdominal wall reconstruction (AWR); however, there is no universally agreed upon instrument. We review the instruments used in AWR and report their utilization trends within the literature. This scoping review was reported according to the Preferred Reporting Items for Systematic Reviews and Meta-analysis extension for Scoping Reviews guidelines using the PubMed, Embase, Web of Science, ClinicalTrials.gov, and Cochrane databases. All published articles in the English language that employed a quality-of-life assessment for abdominal wall hernia repair were included. Studies which focused solely on aesthetic abdominoplasty, autologous breast reconstruction, rectus diastasis, pediatric patients, inguinal hernia, or femoral hernias were excluded. Six hernia-specific tools and six generic health tools were identified. The Hernia-Related Quality-of-Life Survey and Carolinas Comfort Scale are the most common hernia-specific tools, while the Short-Form 36 (SF-36) is the most common generic health tool. Notably, the SF-36 is also the most widely used tool for AWR outcomes overall. Each tool captures a unique set of patient outcomes which ranges from abdominal wall functionality to mental health. The outcomes of AWR have been widely studied with several different assessments proposed and used over the past few decades. These instruments allow for patient assessment of pain, quality of life, functional status, and mental health. Commonly used tools include the Hernia-Related Quality-of-Life Survey, Carolinas Comfort Scale, and SF-36. Due to the large heterogeneity of available instruments, future work may seek to determine or develop a standardized instrument for characterizing AWR outcomes. [ABSTRACT FROM AUTHOR]

This article explores the impact of incisional hernias on abdominal wall strength. It highlights that incisional hernias, which commonly occur after abdominal surgeries, can lead to complications and a decrease in quality of life for patients. The study focuses on analyzing abdominal muscle strength in patients with incisional hernias compared to healthy individuals. The results indicate significant differences in abdominal muscle strength between the two groups, suggesting that incisional hernias can have a negative effect on abdominal wall strength. The study also identifies factors such as sex, hernia size, and BMI as influential factors in abdominal strength. It suggests that identifying reduced abdominal strength in individuals with hernias could improve their overall quality of life and inform perioperative management. The study proposes the use of a strain gauge as a cost-effective alternative for assessing abdominal muscle strength. However, it is important to note that the study has limitations, such as not considering baseline physical activity levels and back pain. This information can be valuable for individuals researching the effects of incisional hernias on overall health and quality of life. [Extracted from the article]

Abdominal wall hernia repair, a common surgical procedure, includes various techniques to minimize postoperative complications and enhance outcomes. This review focuses on the comparison between laparoscopic and robotic approaches in treating inguinal and ventral hernias, presenting the ongoing situation of this topic. A systematic search identified relevant studies comparing laparoscopic and robotic approaches for inguinal and ventral hernias. Randomized control trials, retrospective, and prospective studies published after 1 January 2000, were included. Search terms such as hernia, inguinal, ventral, laparoscopy, robotic, and surgery were used. A total of 23 articles were included for analysis. Results indicated similar short-term outcomes for robotic and laparoscopic techniques in inguinal hernia repair, with robotic groups experiencing less postoperative pain. However, longer operative times and higher costs were associated with robotic repair. Robotic ventral hernia repair demonstrated potential benefits, including shorter hospital stay, lower recurrence and lower reoperation rates. While robotic surgery offers advantages such as shorter hospital stays, faster recovery, and less postoperative pain, challenges including costs and training requirements need consideration. The choice between laparoscopic and robotic approaches for abdominal wall hernias should be tailored based on individual surgeon expertise and resource availability, emphasizing a balanced evaluation of benefits and challenges.

Summary: This report outlines the diagnosis, surgical treatment and successful outcome following the treatment of a foal presented with a congenital abdominal hernia. A focal ventral abdominal swelling, enlarging since birth, starting just caudal to the intact umbilicus and extending caudally over the prepuce was observed. Once in dorsal recumbency, the hernia was found to originate from a defect of the abdominal wall in the linea alba region. A simple closed herniorrhaphy with inversion of the large peritoneal sac into the abdomen was performed. Post‐operative complications included fever with the development of an abscess at the surgical site. This was diagnosed and drained with ultrasound guidance. Based on culture and sensitivity testing of the abscess exudate, antibiotic therapy was adapted and the foal made a full recovery. A clinical examination undertaken 1 year later revealed complete healing of the linea alba. Herniation due to a muscle wall default has not been previously reported in foals. This article reviews the commonly observed causes of herniation (umbilical and inguinal hernias). However, a third type of congenital ventral body wall hernia should be considered for the differential diagnosis of swelling of the preputial area in foals. [ABSTRACT FROM AUTHOR]

Lumbar incisional hernia is an uncommon complication that affects the abdominal wall integrity, accounting for approximately 3.5% of all cases. It typically occurs following open nephrectomy or aortic aneurysm repair surgeries. Although rare, lumbar hernias can lead to discomfort, aesthetic issues, or even intestinal obstruction. In extremely rare cases, lumbar herniation of the liver can occur. Here, the authors present a case of a 60-year-old female patient with liver herniation through a lumbar incisional hernia and a history of pyelolithotomy for renal calculi. The authors performed an open hernia repair with meshplasty. Lumbar incisional hernias are rare and still difficult to manage. Computed tomography is the diagnostic method of choice in the evaluation of the parietal wall defect to choose the appropriate therapeutic management. Surgical management modalities are still poorly codified, with no precise recommendations, and this is probably due to the relative rarity of the cases. [ABSTRACT FROM AUTHOR]

Introduction: Spiegel-Casseri’s hernia (HSC) is an infrequent entity that represents about 2 % of abdominal wall herniary defects, but frequency could be increased due to its subdiagnosis. The diagnosis of HSC is usually diffi cult and unsuspected and it presents high risk of jamming and strangulation so its surgical management is imperative. A TC is essential for diagnosis. Case report: Male, with pathological antecedents of myasthenia gravis, who consults about bilateral inguinal hernia and left Spiegel-Casseri’s hernia. Due to his clinical history, an open preperitoneal surgical approach with Lichtenstein plastic to repair all the three defects is done. During the postoperative, he had a bruise on the dropped hernial sac, treated with conservative measures and control and didn’t require drainage. Discussion: Most series of notifi ed cases of HSC in the literature show variable incidence of attendant abdominal wall’s defects. In this case, myasthenia gravis, a chronic and weakening disease, prompted three associated parietal defects and limited anesthesiologist options and surgical approaches. HSC is an unusual entity and its association with others hernias even more, but it exists and must be taken into account to achieve an optimal treatment for the patient. [ABSTRACT FROM AUTHOR]

Background: Groin hernia repair is one of the most common operations performed globally, with more than 20 million procedures per year. The last guidelines on groin hernia management were published in 2018 by the HerniaSurge Group. The aim of this project was to assess new evidence and update the guidelines. The guideline is intended for general and abdominal wall surgeons treating adult patients with groin hernias. Method: A working group of 30 international groin hernia experts and all involved stakeholders was formed and examined all new literature on groin hernia management, available until April 2022. Articles were screened for eligibility and assessed according to GRADE methodologies. New evidence was included, and chapters were rewritten. Statements and recommendations were updated or newly formulated as necessary. Results: Ten chapters of the original HerniaSurge inguinal hernia guidelines were updated. In total, 39 new statements and 32 recommendations were formulated (16 strong recommendations). A modified Delphi method was used to reach consensus on all statements and recommendations among the groin hernia experts and at the European Hernia Society meeting in Manchester on October 21, 2022. Conclusion: The HerniaSurge Collaboration has updated the international guidelines for groin hernia management. The updated guidelines provide an overview of the best available evidence on groin hernia management and include evidence-based statements and recommendations for daily practice. Future guideline development will change according to emerging guideline methodology. [ABSTRACT FROM AUTHOR]

The most prevalent type of abdominal wall hernias are inguinal. Although the prevalence of inguinal hernias is unknown, roughly 500,000 cases are treated in hospitals annually. There is a dearth of information on inguinal hernia primary and recurrence rates in our nation. to compare the age- and gender-specific prevalence rates of inguinal hernia. to estimate the prevalence of inguinal hernia among various age groups. According to the study, those between the ages of 41 and 50 (29.29%) are the most susceptible to developing an inguinal hernia. Eighty eight percent of the patients were men. The most frequent hernia among patients was on the right side. In the study population, heavy object lifting and chronic coughing were frequently identified as risk factors. Our findings may serve as a useful guide for future research on the frequency of inguinal hernias in general populations. [ABSTRACT FROM AUTHOR]

Interparietal inguinal hernia, an exceedingly rare type of inguinal hernia in which the hernia sac anatomically lies between the tissue layers of the abdominal wall, is difficult to diagnose from physical findings. Given the few reports on interparietal inguinal hernias, this condition has remained fairly unrecognized. Herein, we report the successful imaging and laparoscopic diagnoses as well as repair of an interparietal inguinal hernia. Atypical physical findings and computed tomography data help in the diagnosis of an interparietal inguinal hernia. The laparoscopic approach is useful and feasible for both the diagnosis and treatment of interparietal inguinal hernia. [ABSTRACT FROM AUTHOR]

Introduction: In the last decade, groin pain has become the main complication of hernioplasty and a major public health problem. This problem can only be controlled by ensuring adequate knowledge of lumbar neuroanatomy. The objective of this work is to review the history of inguinal neuroanatomy in relation to hernia pathology and the specialty of the abdominal wall. Method: Literature review of PubMed, LILACS, Cochrane Library databases; supplementary search using Google (Google Play), of university libraries. As keywords have been used: “lumbar plexus”, “inguinal nerves”, “ilioinguinal nerve”, “iliohipogastric nerve”, “genitocrural nerve”, “hernia”, “anatomy” and “surgery”. A critical analysis of published articles, theses, books and monographs is carried out. Manuscripts obtained from any country, by any institution or researcher and in any language, without time limit, are stored in pdf format. Results: The study of the history of the inguinal nerves with current methodology shows the succession of knowledge until reaching the current anatomical terminology and in parallel, the development of surgical techniques until neural pathology is considered of interest. Conclusions: Schmidt’s study offers us the most recognized descriptive topography with the first advice on clinical problems associated with neural injury during a hernia operation. His classification is the one adopted as official anatomical terminology. The concepts of the intramuscular plexus of the psoas and the iliac fossa anastomotic system were introduced by the Spaniard Gómez Durán (1923). A clear disconnection between the advances in hernia and neural anatomical-surgical knowledge is demonstrated, with a delay of two centuries in its topographical application to the abdominal wall specialty.

Lumbar hernias are congenital or acquired posterolateral abdominal wall hernias and are located in the superior or inferior lumbar triangle. Traumatic lumbar hernias are rare, and the optimal method to repair these is not well-defined. We present the case of a 59-year-old obese female who presented after a motor vehicle collision with an 8.8 cm traumatic right-sided inferior lumbar hernia and overlying complex abdominal wall laceration. The patient underwent an open repair with retro rectus polypropylene mesh and biologic mesh underlay several months after the abdominal wall wound healed, and the patient lost 60 pounds. The patient recovered well without complications or recurrence at the one-year follow-up. This case demonstrates a complex, open surgical approach to repair a large traumatic lumbar hernia not amenable to laparoscopic repair. [ABSTRACT FROM AUTHOR]

Background: Inguinal hernia repair is a commonly performed general surgery procedure in both adults and children with inguinal hernias constituting more than 95% of all groin hernia repairs. The present study was conducted to assess risk factors of inguinal hernia. Materials & Methods: 94 cases of inguinal hernia of both genders were enrolled. Parameters such as the type of hernia, primary or recurrent was noted. Period of swelling, side and risk factors were recorded. Results: Out of 94 patients, males were 60 and females were 34. Side was right in 28, left in 30 and bilateral in 36. Type of hernia was primary in 54 and recurrent in 40. Period of swelling was <1 year in 32, 1-2 years in 40 and >2 years in 22. The difference was significant (P< 0.05). Common risk factors for inguinal hernia were COPD in 24, lifting heavy objectsin 88, alcoholism in 26, smoking in 34, diabetes in 30, family history in 11, bowel disturbances in 72 and age >60 yearsin 26. The difference was significant (P< 0.05). Conclusion: Common risk factors for inguinal hernia were COPD, lifting heavy objects, age >60 years, alcoholism, smoking, diabetes, family history and bowel disturbances. [ABSTRACT FROM AUTHOR]

Introduction: The aim of this study was to investigate the safety and efficacy of performing minilaparoscopy compared with standard laparoscopy in the treatment of cryptorchidism with an ipsilateral inguinal hernia. Materials and Methods: In total, 46 patients with cryptorchidism and an ipsilateral inguinal hernia were admitted to the Urology and Hernia and Abdominal Wall Surgery Departments of Beijing Chaoyang Hospital between October 2009 and July 2019. They were assigned to two groups: Group M and Group S. In Group M, 24 patients underwent herniorrhaphy and orchiopexy using minilaparoscopy, and in Group S, 22 patients underwent herniorrhaphy and orchiopexy using standard laparoscopy. Surgeons chose the procedure at random, and the patients were blinded to the selected procedure. Results: Postoperative painkiller demand (P = .043) and first postoperative day Numerical Rating Scale scores (P = .032) were lower in Group M than Group S, and the average hospital stay was shorter (P = .041) in Group M. Furthermore, 21 of the 24 procedures in Group M were successful, 3 procedures of Group M were converted from mini- to standard laparoscopy, and all 22 procedures in Group S were successful. The Observer Scar Assessment Scale questionnaire results of Group M were significantly higher than for patients in Group S (P = .038). Conclusion: Our findings suggest that treatment of cryptorchidism with ipsilateral inguinal hernia using minilaparoscopy is as safe and effective as standard laparoscopy. [ABSTRACT FROM AUTHOR]

Purpose: To reveal the clinical significance of preoperative haematological inflammatory markers in the diagnosis of abdominal wall hernias with strangulation. Methods: The data of 200 patients who underwent surgery for incarcerated hernia were retrospectively analysed. The patients were grouped into three groups; Group 1; only surgical reduction and hernia repair, Group 2; small bowel resection and Group 3; omentum resection. Age, gender, hernia type, the presence of radiological bowel obstruction and preoperative complete blood count data were obtained. Neutrophil-leukocyte ratio (NLR), lymphocyte-monocyte ratio (LMR), platelet-lymphocyte ratio (PLR), haematological inflammatory index (HII) and systemic immune-inflammation index (SII) values were calculated. Results: The study was consisted of; Group 1: 119 patients (59.5%), Group 2: 46 patients (23%) and Group 3: 35 patients (17.5%). Advanced age (p = 0.001), female gender (p = 0.036), incisional hernias (p = < 0.001) and the presence of bowel obstruction (p = < 0.001) were found to be statistically significant in terms of strangulation. NLR, PLR and SII values were significantly higher in Group 2 compared to Group 1, and PLR values were significantly higher in Group 2 compared with Group 3 (p < 0.05). Conclusion: The preoperative elevated NLR, PLR and SII values may indicate strangulation and possible intestinal resection, in incarcerated abdominal wall hernias. [ABSTRACT FROM AUTHOR]

Purpose: We introduce a novel approach to the surgical repair of Morgagni hernias (MHs) utilizing the robotic transabdominal preperitoneal repair (rTAPP) approach. Borrowed from our previous and robust experience with rTAPP repairs for hernias of the anterior abdominal wall, this technique boasts the benefits of hernia sac reduction, the use of an uncoated mesh in an extraperitoneal plane, and minimal fixation leading to lower postoperative pain relative to other approaches. Methods: To evaluate the effectiveness of this novel approach, five consecutive symptomatic Morgagni hernias (MHs) were repaired with the rTAPP approach. The size of the defect, mesh size, length of stay, follow-up imaging, and follow-up complications were documented for comparison. Results: The size of the MH defects ranged from 4 × 6 cm to 5 × 10 cm. LOS was an average of 1.2 days. Two out of the five patients underwent concomitant repair of a lower abdominal hernias (one Spigelian hernia, and one indirect inguinal hernia). Outpatient follow-up from surgery ranged anywhere from 6 months to 4 years, with most patients receiving follow-up after 1 year. Four out of the five patients received follow-up CT scans to confirm the absence of hernia recurrence. One patient experienced an incisional hernia from the midline 12-mm port site which was repaired 1 year after. Conclusion: We propose a new technique for a minimally invasive strategy to treat these complex hernias utilizing an rTAPP technique resulting in minimal length of stay and a durable result in long-term follow-up. The benefits of repair, which include minimal postoperative pain, minimal length of stay, and cost-effective prosthetic mesh hidden from the visceral contents, are consistent with the author's experience for rTAPP repairs for hernias of the anterior abdominal wall.

Herniation of a gravid uterus through an abdominal wall incisional hernia with overlying skin necrosis is exceptionally rare. A 29-year-old multiparous K30 + 4/40 pregnant female presented with a 1-month history of worsening abdominal wall skin changes. Magnetic resonance imaging of the abdomen and pelvis confirmed herniation of the gravid uterus into the hernia sac. A lower uterine segment caesarean section and hernia repair were performed by the general surgical and obstetrics team in view of the potential maternofoetal complications. This case highlights the importance of early recognition and the difficulties in managing gravid uterus herniation. [ABSTRACT FROM AUTHOR]

A 73‐year‐old woman presented to our hospital because of painful bulging in the right lower abdomen, and developed a 17 × 12 cm incisional hernia after kidney transplantation using right oblique incision. Laparoscopic intraperitoneal onlay mesh (IPOM) repair was performed. Since a transplanted kidney is close to the abdominal wall defect, the space between the transplanted kidney and the abdominal wall was peeled off to secure enough space for the mesh to be place. After that the fascial defect was detected precisely, and the polypropylene‐polyglycolic acid composite mesh was fixed with 3 cm overlapping of the hernia ring by non‐absorbable tacks. The patient was discharged 9 days after surgery. In general, abdominal incisional hernias after kidney transplantation are relatively large with boundary defect of abdominal wall ensuing between the abdominal and allograft. However, laparoscopic IPOM repair of incisional hernia after kidney transplantation can be performed safely and effectively. [ABSTRACT FROM AUTHOR]

Introduction: Multiple minimally invasive techniques have been described for ventral hernia repair. The recently described enhanced view totally extraperitoneal (eTEP) ventral hernia repair seems an appealing option since it allows to address midline and lateral hernias, placing the mesh in the retromuscular position without the use of traumatic fixation. Aim: To report on the mid-term result of a series of patients with ventral hernias repaired by the eTEP approach. Methods: A retrospective analysis of our case series between June 2017 and December 2019. Demographic and clinical data were gathered. Hernia characteristics, surgical details, hernia recurrences, and complications are reported. Results: 66 patients were included in the study. Median follow-up was 22 months (interquartile range 12–26). 60% of patients were male. Mean age, BMI, % of Type-2 diabetes and % of smoking were 59 ± 12 years, 30 kg/m2, 24% and 23%, respectively. Mean hernia defect size was 5.5 ± 2.9 cm. Forty-three eTEP Rives-stoppa and 23 eTEP-Transversus abdominis release (14 unilateral, 9 bilateral) were performed. 22 inguinal hernias and 15 lateral defects were simultaneously repaired. We report 1 recurrence (1.5%) and 10 surgical site occurrences (15%; 6 seromas, 2 hematomas and 2 surgical site infections). Four patients required reinterventions (6%). Conclusion: eTEP is a promising approach to treat midline hernias and allows the simultaneous treatment of lateral and inguinal defects, keeping the mesh in the retromuscular position. However, comparative studies must be performed to know its real benefit in laparoscopic ventral hernia repair. [ABSTRACT FROM AUTHOR]

Purpose: Long delays in waiting lists have a negative impact on the principles of equity and providing timely access to care. This study aimed to assess waiting lists for abdominal wall hernia repair (incisional ventral vs. inguinal hernia) to define explicit prioritization criteria. Methods: A cross-sectional single-center study was designed. Patients in the waiting list for incisional/ventral hernia (n = 42) and inguinal hernia (n = 50) repair were interviewed by phone and completed health-related quality of life (HRQoL) questionnaires (EQ-5D, COMI-hernia, HerQLes) as a measure of severity. Priority was measured as hernia complexity, patient frailty using the modified frailty index (mFI-11), and the consumption of analgesics for hernia. Results: The mean (SD) time on the waiting list was 5.5 (3.2) months (range 1–14). Complex hernia was present in 34.8% of the patients. HRQoL was moderately poor in patients with incisional/ventral hernia (mean HerQL score 66.1), whereas it was moderately good in patients with inguinal hernia (mean COMI-hernia score 3.40). The use of analgesics was higher in patients with incisional/ventral hernia as compared with those with inguinal hernia (1.48 [0.54] vs. 1.31 [0.51], P = 0.021). Worst values of mFI were associated with inguinal hernia as compared with incisional/ventral hernia (0.21 [0.14] vs. 0.12 [0.11]; P = 0.010). Conclusion: Explicit criteria for prioritization in the waiting lists may be the consumption of analgesics for patients with incisional/ventral hernia and frailty for patients with inguinal hernia. A reasonable approach seems to establish separate waiting lists for incisional/ventral hernia and inguinal hernia repair. [ABSTRACT FROM AUTHOR]

Objective: Rare disease Background: The term "sclerosing mesenteritis" includes a spectrum of rare idiopathic diseases involving the small and/or large bowel. It appears as a diffuse, localized, or multinodular thickening of the mesentery, with a variable degree of chronic non-specific inflammation, fat necrosis, and fibrosis. Case Report: Here, we report a case of 83-year-old woman with symptoms of intestinal occlusion, vomiting, and abdominal pain. Radiographic examinations showed air fluid levels in right and left quadrants and in the mesogastric site, while computed tomography (CT) documented a strangulated inguinal hernia with ileal obstruction. Based on clinical examination and radiologic findings, the patient underwent surgery for inguinal hernia reduction. The examination of viscera revealed 2 tracts of ileum with ischemic signs and covered by fibrin; thus, the 2 intestinal loops were resected. Histological examination revealed chronic non-specific inflammation of the whole intestinal wall, including the subserosa in the resected tract of proximal ileum, while the distal ileal loop (not herniated tract) showed a subserosal fibrous nodule of 2 cm in greatest diameter, composed of a proliferation of spindle cells haphazardly arranged in a collagenized stroma. The diagnosis of sclerosing mesenteritis was rendered. Conclusions: The present case shows the possibility of an incidental diagnosis during another intervention such as hernia surgery. Pathologists should be aware of this disease to avoid confusion with aggressive tumors such as intraabdominal desmoid-type fibromatosis and gastrointestinal stromal tumor. [ABSTRACT FROM AUTHOR]

Laparoscopic ventral hernia repair with intraperitoneal onlay mesh reinforcement is often performed in clinical practice. We herein describe a patient who developed a Spigelian hernia at the edge of the mesh due to rupture of the muscular layer in the abdominal wall. A 69‐year‐old woman developed a left‐sided abdominal bulge 15 months after laparoscopic ventral hernia repair. CT showed a 33‐mm defect in the abdominal wall at the lateral edge of the left abdominal rectus muscle with an intestinal prolapse through the defect. She was diagnosed with a Spigelian hernia and underwent operation. The hernia orifice was located at the aponeurosis of the transverse abdominal muscle where the thread had been used to fix the mesh through all layers of the abdominal wall. This report details a case of a Spigelian hernia after laparoscopic ventral hernia repair. [ABSTRACT FROM AUTHOR]

Background: A hernia is defined as a protrusion from a structure through the normally tissues containing it, either a focal or diffuse defects in the tissues with many types including: inguinal, femoral, umbilical and paraumbilical, epigastric and incisional hernias. Objective: This study aimed to evaluate anterior abdominal wall hernia using ultrasound and color Doppler. Patients and methods: An interventions study included (48) patients who were referred from the Surgery Department, Zagazig University Hospitals for sonographic evaluation of the abdominal wall and the abdomen when their clinical presentations were suggestive of abdominal wall hernia obstruction, either progressed or not progressed to bowl obstruction, when their physical examinations were inconclusive or when surgeons believed it was important to determine the contents of a suspected hernia preoperatively. Results: The mean age of the studied patients was 47.5 ± 21.88 years old, with a range from 3 months to 66 years old, less than ½ of the studied patients were males (41.7%) and 58.3 % were females. About 100% of the studied hernias were irreducible containing omentum, while hernias were containing bowel in 95.8% of cases, 41.7 % of cases contained free fluid in hernia sac, 47.8% of the studied patients had absent bowel peristalsis. Comparing the ultrasound finding with the operative data revealed that ultrasound had 100% sensitivity, while accuracy in diagnosis of peristalsis, bowel irreducibility, bowel thickness ranged from 93.4% to 98.8%. Conclusion: High-resolution ultrasonography (US) is an efficient tool for detecting the presence of abdominal wall hernias and accurately detecting the content, and the possible associated complications.

Background/aim: Lumbar hernia is caused by a defect in the abdominal wall. Due to its rarity, there is no established consensus on optimal treatment for lumbar hernia yet. Thus, we here investigated the clinical, surgical characteristics and outcomes of lumbar hernia by collecting 28 such patients from our hospital.Methods: Patients diagnosed with lumbar hernia from our institution between April 2011 and August 2020 were retrospectively collected in this study. Demographics, clinical characteristics and surgical information were recorded.Results: A consecutive series of 28 patients with lumbar hernia were retrospectively collected, including 13 males (46%) and 15 females (54%). The ages of the patients ranged from 5 to 79 years (median: 55 years), with a mean age of 55.6 ± 14.9 years. A total of 7 cases had a history of previous lumbar trauma or surgery. There were 11 (39%), 15 (54%) and 2 (7.1%) cases had right, left and bilateral lumbar hernia, respectively. Superior and inferior lumbar hernia were found in 25 (89%) and 3 (11%) patients. General anesthesia was adopted in 16 cases (group A), whereas 12 patients received local anesthesia (group B). Patients in the group B had a shorter hospital stay than that of the group A (3.5 ± 1.3 days vs. 7.1 ± 3.2 days, p = 0.001), as well as total hospitalization expenses between the two groups (2989 ± 1269 dollars vs. 1299 ± 229 dollars, p < 0.001). With a median follow-up duration of 45.9 months (range: 1-113 months), only 1 (3%) lumbar hernias recurred for the entire cohort.Conclusions: Lumbar hernia is a relatively rare entity, and inferior lumbar hernia is rarer. It is feasible to repair lumbar hernia under local anesthesia. [ABSTRACT FROM AUTHOR]

Biologic response to hernia prostheses represents a continuous source of debate. Conventional hernia meshes, in their typical static, passive configuration have been used for decades to reinforce the herniated abdominal wall. These flat implants, mainly fixated with sutures or tacks, induce poor quality fibrotic ingrowth that shrinks the mesh. In groin hernia repair, flat meshes are applied in the delicate inguinal surrounding where uncontrolled development of a scar plate can impair movement and may incorporate the sensitive nerves crossing this area. Complications deriving from mesh fixation and nerve entrapment are frequent and unpleasant for patients. To remedy these problems, a multilamellar shaped 3D device with a dynamic responsive behavior has recently been developed to repair inguinal hernia. Its inherent dynamic compliance during inguinal movements has shown to induce enhanced biological response with ingrowth of newly formed connective tissue, muscle fibers, and nerves. The function of these highly specialized tissue structures is supported by the contextual development of newly formed arteries and veins. The scope of the study was to assess quantity and quality of vessels, which had ingrown in the 3D hernia device in the short‐term, medium‐term, and long‐term post‐implantation, in biopsy specimens gathered from inguinal hernia patients operated with the 3D device. Starting from an early stage, widespread angiogenesis was evident within the 3D structure. Arteries and veins increased in quantity showing progressive development until full maturation of all specific vascular components throughout the mid‐term, to long‐term, post‐implantation. High quality biologic ingrowth in hernia prosthetics needs an adequate vascular support. The broad network of mature arteries and veins evidenced herewith seems to confirm the enhanced biological features of the dynamic responsive 3D device whose features resemble a regenerative scaffold, an ideal feature for the treatment of the degenerative source of inguinal hernia disease.

Introduction: The proportion of epigastric hernias in the total collective of all operated abdominal wall hernias is 3.6–6.9%. The recently published guidelines for treatment of epigastric hernias of the European Hernia Society and the Americas Hernia Society recommend the use of a mesh for defect size of ≥ 1 cm, i.e., a preperitoneal flat mesh technique for sizes 1–4 cm, and laparoscopic IPOM technique for defects > 4 cm and/or obesity. Against that background, this analysis of data from the Herniamed Registry now aims to explore trends in epigastric hernia repair. Methods: To detect trends, the perioperative outcome was calculated separately for the years 2010 to 2019 and the 1-year follow-up for the years 2010 to 2018 and significant differences were identified. Analysis was based on 25,518 primary elective epigastric hernia repairs. The rates of postoperative surgical complications, pain at rest, pain on exertion, chronic pain requiring treatment and recurrence associated with the various surgical techniques were calculated separately for each year. Fisher's exact test for unadjusted analysis between years was applied with Bonferroni adjustment for multiple testing. Results: The proportion of laparoscopic IPOM repairs declined from 26.0% in 2013 to 18.2% in 2019 (p < 0.001). Instead, the proportion of open sublay repairs rose from 16.5% to 21.8% (p < 0.001). That was also true for innovative techniques such as the EMILOS, MILOS, eTEP and preperitoneal flat mesh technique (8.3% vs 15.3%; p < 0.001). This change in indication for the various surgical techniques led to a significant improvement in the postoperative surgical complication rate (3.8% vs 1.9%; p < 0.001). Conclusion: The trend is for epigastric hernia repair to be performed less often in laparoscopic IPOM technique and instead more often in open sublay technique or the new innovative techniques.

The association between Morgagni hernia and Menkes disease has not yet been described. Here, we report such a rare association in an 8‐year‐old boy who presented with subocclusive symptoms. He successfully underwent laparoscopic repair with a patch. The patch was fixed to the anterior abdominal wall by using transfascial sutures with extracorporeal knot tying and to the remaining edges of the diaphragmatic defect by using intracorporeal suturing and spiral tacks. At the 2‐year follow‐up, the child remained recurrence‐free and without gastrointestinal symptoms. The potential relationship between the two conditions and the controversial use of spiral tacks to affix the mesh to the diaphragm are also discussed. [ABSTRACT FROM AUTHOR]

Single‐incision laparoscopic repair of a congenital Morgagni diaphragmatic hernia using a suture‐assisting needle was performed in a 1‐year‐old boy. Three ports were inserted through a single umbilical incision to repair the 2.5 × 2.3‐cm defect. The full‐thickness muscle layer of the anterior abdominal wall and the posterior rim of the defect were penetrated with the suture‐assisting needle holding a thread, which was then released. The needle tip was pulled back over the muscle layer, shifted laterally, and again passed through the muscle layer and the posterior rim. The thread was then captured by the needle and pulled out through the anterior abdominal wall. Five mattress sutures were placed in this way and tied subcutaneously. The postoperative course was uneventful, and the cosmetic outcome was favorable. A suture‐assisting needle is useful for completing full‐thickness anterior abdominal wall repair, which is important for preventing the recurrence of a congenital Morgagni diaphragmatic hernia.

Background: This study systematically reviewed the literature regarding perioperative mortality in human adults undergoing elective surgical abdominal wall hernia repair, including an audit of the Royal Australasian College of Surgeons (RACS) Australian and New Zealand Audit of Surgical Mortality (ANZASM) database. Methods: A systematic review was conducted in accordance with PRISMA guidelines for the reporting of systematic reviews and meta‐analysis of observational studies. Cochrane Library, PubMed, MEDLINE and Embase database searches and data extraction were conducted from June 1979 to October 2019. Statistical analysis was undertaken utilising denominator values for elective hernia procedures derived from the Australian Institute of Health and Welfare (AIHW) data. Risk‐adjusted perioperative mortality rates for the relevant procedures were also produced, using a binary logistic regression for the risk adjustment. Results: Through systematic review of the literature, it was established that the overall reported perioperative mortality in human adults undergoing elective surgical abdominal wall hernia repair was low (0.1%–0.5%). Using ANZASM and AIHW data, the calculated risk‐adjusted mortality rate for Australian patients was found to be significantly lower (0.04%–0.06%, p < 0.001). Conclusion: The risk‐adjusted mortality rate for elective abdominal wall hernia surgery in Australia is very low and compares favourably to international cohorts. Despite low absolute numbers, the factors which were most significantly associated with increased perioperative mortality in patients undergoing elective surgical abdominal wall hernia repair were increased age, cardiorespiratory co‐morbidity and incisional hernia repair.

Background: The use of mesh in hernia repair has faced intense scrutiny, leading patients to become fearful of its use, despite its benefits in reducing hernia recurrence. We report a single institutional experience in performing hernia repair with mesh in terms of hernia-specific outcomes, mesh-related complications, and patient-reported quality of life.Study Design: Patients who underwent abdominal wall hernia repair with mesh at a single institution were identified from a prospectively maintained quality database. Demographic, perioperative, and postoperative outcomes data were analyzed. Surgical Outcomes Measurements System (SOMS) and Carolinas Comfort Scale (CCS) surveys were administered pre- and postoperatively at 3 weeks, 6 months, 1, 2, and 5 years.Results: Between 2010 and 2020, a total of 6,387 patients underwent abdominal hernia repair with mesh. Inguinal hernia repairs made up the majority (65%) of the operations. Rates of mesh infection varied by hernia type, with lower rates after umbilical (0.0%) and inguinal (0.4%) repair, and highest after incisional repair (1.3%). Similarly, mesh explantation rates were low after umbilical and inguinal repair (0.0% and 0.4%, respectively) and highest after incisional repair (3.0%). Scores on all SOMS domains were significantly improved from baseline (all p < 0.05). On CCS, 2.9%, 3.3%, and 4.4% of patients reported severe or disabling symptoms postoperatively at 1, 2, and 5 years, respectively.Conclusions: Rates of mesh-related complications vary by hernia type. A majority of patients report excellent long-term quality of life, although a relatively large percentage of patients experience severe or disabling symptoms at long-term follow-up.

Background: Morgagni hernias (MHs) are rare anteromedial congenital diaphragmatic hernias. This study describes the effectiveness of a laparoscopic approach for these defects. Methods: A prospectively collected institutional database at a tertiary referral center was queried for patients (≥18 years) with MHs. Results: Fifteen adults underwent laparoscopic MH repair. Abdominal pain was the most common presentation (71.5%), and 2 patients (13.3%) presented with acute obstruction. Laparoscopic bridged mesh repair was the most common approach (66.7%) and was achieved by suturing a bridged synthetic mesh to the diaphragmatic portion of the defect and fixing it with transfascial sutures and/or tacks to the anterior abdominal wall. Primary suture repair was utilized for smaller defects. No mortalities or recurrences occurred after 20.2 months median follow-up. Conclusions: Laparoscopic synthetic mesh repair of adult MHs offers an effective hernia repair with minimal complications and no detected recurrences in long-term follow-up of this patient sample.

Background: Obturator hernia is rare and accounts for less than 1% of all abdominal wall hernias. It represents a diagnostic challenge due to its nonspecific signs and symptoms.Case Presentation: We present a case of an 89-year-old caucasian female with a 12-hour history of right medial thigh pain. Computed tomography scan revealed a right obturator hernia with small bowel obstruction. The hernia was successfully repaired laparoscopically without any need for small bowel resection. She was discharged on postoperative day 2 with an uneventful recovery and zero complications.Conclusion: This case report highlights the importance of rapid diagnosis and repair of obturator hernia even in the setting of an improving clinical picture. It also demonstrates the safety of laparoscopic repair in this setting. [ABSTRACT FROM AUTHOR]

Introduction: Hernias are a common surgical condition. Most guidelines recommend repair in almost all cases. NHS Devon clinical commissioning group (CCG) guidelines restrict the commissioning of hernia repair. The aim of this study was to follow up a cohort of patients referred for hernia repair to assess the impact of commissioning guidelines on clinical outcomes. Methods: All patients referred to a single UK surgeon with an abdominal wall hernia over a 12-month period were followed up to determine whether CCG criteria were initially met. If they were not, time to any subsequent surgical intervention was recorded. Results: After exclusions, 106 patients referred for abdominal wall hernia repair were followed up. Of these, 53 (49%) fulfilled commissioning guidelines for surgical repair. Thirty-one patients (23%) who had an indication for surgical repair did not fulfil commissioning criteria. This group was followed up for a median of 1,112 days (range: 962–1,287 days). Twelve patients (39%) required an operation within 900 days with one of these (3%) requiring emergency repair. These 12 patients waited a mean of 232 days before being accepted for surgery. Conclusions: A large number of patients who did not initially meet NHS Devon CCG's criteria ultimately required surgery. Three per cent of this 'watch and wait' group required emergency repair. NHS Devon CCG guidelines do not effectively identify patients who can be managed safely without surgical hernia repair. The incidence of emergency repair in this group should inform the prioritisation of hernia repairs when restarting elective services that have been halted because of the COVID-19 pandemic.

Traumatic abdominal wall hernia (TAWH) in children is an uncommon injury and most commonly occurs after blunt abdominal trauma. There is no consensus on the management of these rare cases. We performed a systematic review of the literature to describe injuries, management, and outcomes. Following Preferred Reporting Items for Systematic Reviews and Meta Analyses (PRISMA) guidelines, a systematic literature search of PubMed, Web of Science, Embase, and Google Scholar was performed to identify English-language publications of blunt TAWH in patients <18 y old. Conflicts were resolved by consensus. Data were collected on demographics, associated injuries, management, and outcomes. A total of 71 articles were reviewed with 100 cases of TAWH. A total of 82.5% of patients were male, and the median age was 9 y old (range 2-15). Injury by bicycle handlebars was most common (72%) followed by motor vehicle collision (14%). Forty patients had intraabdominal injuries, most commonly bowel (70%) or mesentery (37.5%). Rate of intraabdominal injury was significantly higher in patients with injuries due to nonbicycle handlebar injuries when compared with bicycle handlebar injuries (60.7% versus 33.3%, P = 0.02). Most patients were managed operatively (85%), most commonly via laparotomy (68/85, 80%), with six laparoscopic repairs and five laparoscopic converted to open repairs. There were three reported complications and no recurrences over a median of follow-up of 5 mo in patients who underwent repair. Pediatric TAWH is a rare injury with a high rate of intraabdominal injuries, particularly when due to high-impact mechanisms such as motor vehicle collision. Although open repair is more commonly performed, laparoscopic repair has been described with success. Recurrence rates appear low, but follow-up has been short term. [ABSTRACT FROM AUTHOR]

Purpose: Primary midline hernias arising in the linea alba are common. While mesh repair has been shown to reduce recurrence rates even in small hernias, many surgeons still use a suture repair for defects of less than 2 cm. The recent European and Americas Hernia Societies Guidelines recommended suture repair only for hernias smaller than 1 cm. A suture repair implies edge-to-edge or overlapping fascial margins, which necessarily involves tension on the repair. A darn is a tension-free repair where, in effect, a "mesh" is hand-woven across the defect in situ. Methods: The darn repair is a modification of the darn techniques for inguinal hernia repair. Eligible patients undergoing this repair at the Royal Infirmary of Edinburgh between 1 January 2008 and 31 December 2017 were identified from a prospective computer-based medical record system and their case notes reviewed. Inclusion criteria were adult patients with a primary midline abdominal wall defect smaller than 2 cm in the widest diameter of the hernia defect measured intra-operatively. Patients were followed up by telephone in 2019. Those who reported possible recurrence or other symptoms in the region of their hernia repair were reviewed in the outpatient clinic. Results: 47 suture-darn repairs were undertaken over the 10-year period. Fifteen of the darn repair operations (32%) were performed under local anaesthesia. Forty-one patients were followed up with a mean of 80 ± 35 and median of 87 months after surgery. Six patients (13%) were lost to follow-up. Recurrence was found in two cases (5%) and one patient has since been diagnosed with a new epigastric hernia some 5 cm cranial to the previous repair. Conclusions: The darn repair for small primary midline hernias is quick and inexpensive with promising long-term results. It can be performed under local anaesthesia. It can serve as an alternative to mesh repair for defects less than 2 cm in maximum dimension. [ABSTRACT FROM AUTHOR]

Purpose: To explore the value of medical three-dimensional visualization technology in precise preoperative assessment of complex abdominal wall defects. Methods: The clinical data of 30 patients were analyzed retrospectively from November 2017 to December 2020 in our department. Ten patients had abdominal wall hernias and 20 patients suffered from abdominal wall tumors. CT examination was performed, and data were stored in the form of DICOM. Three-dimensional reconstruction and related data analysis were performed by Medraw software, which can accurately show the calculation of the abdominal wall defect area, abdominal wall defect classification and zoning. Results: The ratio of the volume of the hernia sac to the whole abdominal volume in 10 patients with abdominal wall hernia was 4.75%. The average ratio of defect area to the whole abdominal wall in 16 patients suffered from abdominal wall tumors was 17.68%. Preoperative three-dimensional reconstruction can accurately obtain an average abdominal wall defect area of 227.83 ± 157.33 cm2 and accurate abdominal wall classification and zoning. Combined with clinical information, we can develop personalized surgical plans for patients. The average operating time was 5.39 ± 2.71 h, respectively, and the average hospital stay was 22.77 ± 11.59 days. The mean follow-up time was 21.09 ± 9.72 months. The incidence of postoperative complications was 23.33% (7/30). The recurrence rates of incisional hernias and abdominal wall tumors were 20.00% (2/10) and 15.00% (3/20), respectively. The patient survival rate was 86.67% (26/30). Conclusion: Three-dimensional visualization technology can be used for the accurate evaluation of patients with complex abdominal defects before surgery and can help surgeons design personalized surgical plans for patients.

Background: Surgical site infection (SSI) is a well-recognized and potentially catastrophic complication of abdominal wall reconstruction (AWR). The authors present a review of the literature surrounding SSI in AWR, exploring prevention and treatment strategies as well as risk factors. Methods: A comprehensive review of the current literature was undertaken. Evidence was reviewed and summarized with particular focus on prevention and treatment strategies available to hernia surgeons. Results: Patient risk factors for SSI are well described in the literature and include obesity, smoking, and other comorbidities. Contaminated hernias and cases involving enterocutaneous fistulae are also at higher risk of SSI. Surgical decisions such as type of mesh, plane of mesh placement, and fascial release may all contribute to SSI risk. To treat established mesh infection, conservative management with antibiotic agents and negative pressure therapy is a reasonable option in some cases. Removal of prosthesis appears to provide favorable results, however, repeat surgery can be problematic Conclusions: Surgical site infection remains an important pathology in the world of AWR. Surgeons have a wealth of tools in their arsenal to prevent and treat SSI and should be aware of the emerging evidence in the fast-moving specialty of hernia surgery. Complex cases should be handled by surgeons and centers with expertise in treating such patients. [ABSTRACT FROM AUTHOR]

Background: Insufficient coverage of the area of a possible groin hernia is an important risk factor in hernia recurrence. To prevent recurrence, it is important to use the appropriate mesh size based on the size of the myopectineal orifice (MPO), which is the weak area of the abdominal wall where inguinal hernias occur. We aimed to estimate the appropriate mesh size for groin hernias by investigating MPO size.Methods: Four hundred and six patients underwent groin hernia repair using a totally extraperitoneal (TEP) approach at the Zeze Hospital between July 2009 and December 2017. We investigated patients' backgrounds, MPO components dimensions, and hernia recurrence, and evaluated the appropriate mesh size.Results: The 359 male and 47 female patients had an average age of 63 ± 15 years. In 171, 147, and 88 cases, hernias were localized to the right, left, and bilaterally, respectively. The number of lateral, medial, femoral, and combined hernias was 317, 124, 11, and 42, respectively. The 95th percentile for the horizontal and vertical lengths in cases of hernia orifice ≥ 3 cm were 9.6 cm and 7.0 cm, respectively, while it was 9.2 cm and 6.4 cm in cases of hernia orifice < 3 cm. We added 2 cm and 3 cm to the 95th percentile for the length and width of the MPO, resulting in 13.2 × 10.4 cm and 15.6 × 13.0 cm in cases with hernia orifice < 3 cm and ≥ 3 cm, respectively. Relapse after TEP occurred in 1 patient (0.2%).Conclusion: The appropriate mesh size for TEP repair, derived from intraoperative MPO measurements, was estimated as 13.2 × 10.4 cm and 15.6 × 13.0 cm when the hernia orifice was < 3 cm and ≥ 3 cm, respectively. Using appropriate mesh sizes based on MPO measurement may reduce groin hernia recurrence after TEP. [ABSTRACT FROM AUTHOR]
