This study's objective is to determine if the combined use of bone substitutes and collagen membranes is related to worse postoperative outcomes after intra-osseous oral cystectomies. Additional risk factors mentioned in the existing literature were retrospectively analysed by reviewing the medical records and imaging tests of adult patients. Age, gender, smoking habit, cyst location, size, shape, histopathology, perilesional osteosclerosis and associated intracystic third molars were registered. The type of biomaterials applied and the number of bony walls remaining after surgery were also identified. All factors were analysed in relation to wound dehiscence and postoperative infection. Simple and multiple logistic regression analyses were performed to exclude possible confounding effects between the risk factors identified. In a sample of 211 cystectomies, guided bone regeneration was not significantly associated with infection, only the presence of impacted third molars was (p = 0.0219). This finding remained true, even in cysts larger than 25 mm. However, the risk of wound dehiscence was 4.9 times higher when biomaterials were applied (CI 95%, 1.6818-12.8274, p = 0.0014). In accordance with recent studies, these findings suggest that whenever guided bone regeneration might prove useful after cyst enucleation, avoiding chemically cross-linked membranes should be considered.

The method of skin closure and post-operative wound management has always been important in orthopedic surgery and plays an even larger role now that surgical site infection (SSI) is a national healthcare metric for both surgeons and hospitals. Wound related issues remain some of the most feared complications following orthopedic trauma procedures and are associated with significant morbidity. In order to minimize the risk of surgical site complications, surgeons must be familiar with the physiology of wound healing as well as the patient and surgical factors affecting healing potential. The goal of all skin closure techniques is to promote rapid healing with acceptable cosmesis, all while minimizing risk of infection and dehiscence. Knowledge of the types of closure material, techniques of wound closure, surgical dressings, negative pressure wound therapy, and other local modalities is important to optimize wound healing. There is no consensus in the literature as to which closure method is superior but the available data can be used to make informed choices. Although often left to less experienced members of the surgical team, the process of wound closure and dressing the wound should not be an afterthought, and instead must be part of the surgical plan. Wounds that are in direct communication with bony fractures are particularly at risk due to local tissue trauma, resultant swelling, hematoma formation, and injured vasculature.

The second article in this continuing medical education series reviews the evidence regarding the intraoperative and postoperative risks for patients and health care workers. We share the most up-to-date recommendations for risk management and postoperative complication management to ensure optimal surgical efficacy and patient safety.

The purpose of this study was to evaluate the clinical outcomes of patients with intractable lateral malleolar bursitis who were treated using the intraoperative saline load test to find communication between the bursal sac and the ankle joint and the quilting sutures after bursectomy to reduce the dead space. We reviewed a total of 28 patients who had been treated with quilting sutures after bursectomy between April 2014 and June 2017. When there was capsular opening detected with the saline load test, it was closed with sutures or augmented with periosteum. On the final follow-up office visit, the lateral malleolus was examined for the recurrence of bursitis. Patient medical records were reviewed for postoperative wound dehiscence, skin necrosis, infections, and nerve symptoms. The saline load test was positive in 11 (42%) cases. The mean foot function index improved from 25.94 ± 20.46 to 11.73 ± 5.27 (p = .003). Fourteen (54%) patients were very satisfied with the results, 9 (35%) were satisfied, 2 (8%) rated their satisfaction as fair, and 1 (4%) was dissatisfied. No cases required skin graft or flap surgery. Intractable lateral malleolar bursitis was successfully treated using the saline load test and quilting sutures after bursectomy. Closure of the capsular opening prevented fluid drainage around the wound. Quilting sutures after bursectomy reduced dead space underneath the wound to prevent fluid accumulation and promoted healing of the skin on the underlying soft tissue.

Summary Background Although acellular dermal matrix (ADM) is widely used in expander-implant-based breast reconstructions, previous analyses have been unable to demonstrate improvements in patient-reported outcomes (PROs) with this approach over non-ADM procedures. This study aims to develop a more selective, evidence-based approach to the use of ADM in expander-implant-based breast reconstruction by identifying patient subgroups in which ADM improved clinical outcomes and PROs. Study design The Mastectomy Reconstruction Outcomes Consortium Study prospectively evaluated immediate expander-implant reconstructions at 11 centers from 2012 to 2015. Complications (any/overall and major), and PROs (satisfaction, physical, psychosocial, and sexual well-being) were assessed two years postoperatively using medical records and the BREAST-Q, respectively. Using mixed-models accounting for centers and with interaction terms, we analyzed for differential ADM effects across various clinical subgroups, including age, body mass index, radiation timing, and chemotherapy. Results Expander-implant-based breast reconstruction was performed in 1451 patients, 738 with and 713 without ADM. Major complication risk was higher in ADM users vs. nonusers (22.9% vs. 16.4% and p = 0.04). Major complication risk with ADM increased with higher BMI (BMI=30, OR=1.70; BMI=35, OR=2.29, interaction p = 0.02). No significant ADM effects were observed for breast satisfaction, psychosocial, sexual, and physical well-being within any subgroups. Conclusion In immediate expander-implant-based breast reconstruction, ADM was associated with a greater risk of major complications, particularly in high-BMI patients. We were unable to identify patient subgroups where ADM was associated with significant improvements in PROs. Given these findings and the financial costs of ADM, a more critical approach to the use of ADM in expander-implant reconstruction may be warranted.

Introduction Nasogastric decompressive tube utilization has been accepted as one of the basic perioperative care measures after esophageal resection surgery. However, with the development of multimodal rehabilitation programs and without clear evidence to support their use, the systematic indication of this measure may be controversial. Material and methods Retrospective, descriptive and comparative study of patients who had undergone Ivor-Lewis esophagectomy in our center – from January 2015 to December 2018 – with placement (Group S), or without placement (Group N) of a decompressive tube in gastroplasty during postoperative period. Epidemiological variables and differences between groups in post-surgical morbidity and mortality, hospital stay, onset of oral tolerance and the need for nasogastric tube placement were evaluated. Results A total of 43 patients were included in this study, with a median age of 61 years, being 86% male. 46.5% were hypertensive, 25.5% had lung disease and 16.3% had diabetes mellitus. The median length of hospital stay was 9 days in group S versus 11.5 days in group N, with no differences in the onset of oral tolerance. Anastomotic dehiscence rate was 5% and 0% respectively. The overall mortality was 2.3% in the first 90 days, without differences between the groups. Placement of nasogastric tube during postoperative period was required only in 1 patient (4.3%) of the group N. Conclusions Non-use of nasogastric tube during postoperative period of an Ivor-Lewis esophagectomy is a safe measure, as it is not associated with a higher rate of complications or hospital stay. This fact may be able to improve patients’ comfort and postoperative recovery.

Background Although controversial, the use of acellular dermal matrices (ADMs) for abdominal wall reconstruction (AWR) is increasing. There are now many different ADMs available, but there is a lack of studies directly comparing ADMs in terms of outcomes. Materials and methods A retrospective chart review was performed to compare perioperative wound complications (up to 120 d postoperatively) between patients who underwent AWR with the human noncrosslinked ADMs Alloderm or Cortiva from January 2012 to March 2020. Surgical technique uniformly consisted of open component separation, onlay implantation of ADM, and progressive tension suture fixation of ADM. Results After exclusions, 53 patients were in the Alloderm group, and 29 patients were in the Cortiva group. The overall perioperative wound complication rate between Alloderm (51.92%) and Cortiva (72.41%) was not significantly different (P = 0.09921). The average follow-up for Alloderm was 76.69 ± 29.52 d and for Cortiva was 66.93 ± 35.16 d (P = 0.2088). There were no cases that required explantation of ADM. Conclusions Given the similar perioperative wound complication profiles, the more cost-effective ADM may be a consideration for use in AWR. The fact that there were zero instances of ADM explantation also supports the use of ADM in these high-risk cases.

Cervical anastomotic leakages may manifest either cervically or intrathoracically. We retrospectively investigated the management strategies and clinical outcomes of patients who developed anastomotic leakages after McKeown esophagectomy and the spectrum of its clinical manifestations.Patients with esophageal cancer who underwent McKeown esophagectomy with cervical anastomosis (n = 749) between January 2015 and December 2018 were included.Cervical anastomosis leakage was diagnosed in 53/749 (7.3%) patients. The leakage was primarily limited to cervical region in 16 (30.2%) patients, whereas intrathoracic spread was present in 37 (69.8%) patients. Intrathoracic manifestations were more commonly accompanied by fever (75.7% vs. 18.8%, P 0.001) and leukocytosis than cervical manifestations (81.1% vs. 25.0%, P 0.001). Compared to patients with cervical manifestations, those with intrathoracic manifestations had a longer duration of hospital stay (median; 58 vs. 40 days, P = 0.006) and higher incidence of tracheal fistula (21.6% vs. 0%, P = 0.045). Drainage through the neck wound was effective in all patients with cervical manifestations. Patients with intrathoracic manifestations who had transnasal inner drain or mediastinal drain placed intraoperatively achieved satisfactory drainage (27/37, 73.0%). Subsequent healing of anastomotic leaks was observed in 50 (94.3%) patients. There was no mortality associated with complications related to anastomotic leakage.Intrathoracic manifestations of cervical anastomotic leakage are common in patients after McKeown esophagectomy. However, they are diagnosed later and are associated with more severe clinical consequences than cervical manifestations. Thus, a high index of suspicion and an early intervention policy for such anastomotic leaks should be adopted and strengthened to decrease the incidence of adverse clinical outcomes.

To investigate why security of identical knot sequences is variable and how to avoid occasionally insecure knots.A factorial design was used to assess factors affecting the security of half knot (H) and half-hitch (S) knot combinations. The effect of tying forces and the risk factors to transform H knots into S knots were investigated. The risk factors evaluated were as follows: starting with an H1 or H2 instead of an H3 knot, inexperience, short sutures, and monomanual knot tying. Security of transformed knots, S2S1 and S2S2 knots, and their recuperation with 2 additional half hitches, SSb or SbSb, were evaluated.Training center for laparoscopic suturing.Not applicable.Security of knots was evaluated in vitro.The forces that caused knot combinations to open before breaking of the suture were used to calculate the risk of opening with low forces. Tying more strongly increased the security of half knots (H2H1sH1s) (p.02) and half hitches (p.001). The forces needed to transform an H3 into an S3 are higher than those for an H2 (p.001), and the risk increases when the surgeon is inexperienced (p.001), when sutures are short (p.001), and when monomanual knot tying (p.001) is used. Inadvertently made S2S1 and S2S2 knots are dangerous, with the exception of the symmetric S2S2, which is stable. Unstable knots such as S2S1a and S2S2a knot combinations improve with 2 additional blocking half hitches (SbSb), but S2S2aSbSb remains occasionally insecure.To reduce the risk of accidentally transforming a first H into an S knot, it is recommended to start with an H3, tie with force, avoid short sutures, and use bimanual suturing. This permits the recommendation to use preferentially H3H2 knots or 5 half hitches (SSSbSbSb). When in doubt, half knot combinations should be secured with at least 2 blocking half hitches.

To evaluate and compare the surgical outcomes and complications of the modified circumcision using disposable circumcision suture device (device group) and the conventional dorsal slit circumcision (conventional group) in children.A total of 284 patients were randomized to either device group or conventional group. All patients were preoperatively assessed and evaluated at 4 weeks after surgery. The perioperative data and postoperative outcomes were compared between the 2 groups.No statistical differences were observed in the average age and indications between the 2 groups preoperatively (P.05). Compared with the conventional group, patients in the device group were shorter mean operative time, less blood loss, lower intraoperative and postoperative pain score, faster incision healing time and a higher satisfaction rate of penile cosmetic appearance (P.01). Similarly, the incidences of complication were significantly lower in the device group than in the conventional group (4.3% vs 12.3%, P.05).The modified circumcision using disposable circumcision suture device is a simple, safe, faster, and effective procedure and may become the attractive alternative to the conventional technique for the children, with a relatively lower complication rate and better cosmetic results. With the improvement of disposable circumcision suture device, the modified circumcision using disposable circumcision suture device has the potential to be widely used in the world.

Background Anastomotic leak (AL) after ileocolic anastomosis influences morbidity, mortality, length of hospitalization and costs. This study analyzes risk and protective factors for AL on ileocolic anastomoses. Methods We retrospectively analyzed our single institution patients' series undergoing elective ileocolic anastomosis for AL between 1/2008-12/2017. AL grade A/B (antibiotic treatment and/or radiological drainage) were summarized as mild, grade C (surgical re-intervention) corresponds to severe AL. Results We included 470 patients (mean age 70.8 years, 43.2% females). Overall AL rate was 9.4% (44 patients) with 6.0% severe and 3.4% mild AL. There was no difference in AL between hand sewn and stapled anastomoses. Multivariate analysis revealed preoperative serum albumin (p = 0.004), smoking habits (p = 0.005) and perioperative blood transfusion (p = 0.038) as risk factors for AL. Suture oversewing as anastomotic reinforcement resulted as independent protective factor (p Conclusion Poor nutritional status, smoking habits and perioperative blood transfusion are negative factors influencing on AL. Suture oversewing as anastomotic reinforcement associates with significantly less AL.

INTRODUCTION Laparoscopic side-to-side intestinal anastomosis is a common in clinic practice and training simulation. The aim of this study is to design and validate a reliable and reproducible tool for its evaluation. METHODS A modified Delphi method was used to design a tool with elements that determine quality, including 5 items: separation between stiches, eversion, tension, leak and iatrogenesis. The study included 21 participants (10 first-year residents and 11 experts) who performed a 5cm laparoscopic intestinal side-to-side anastomosis with porcine viscera. The evaluations were blinded and done independently by 2 evaluators. RESULTS The means obtained by novice and expert participants were, respectively: separation between stiches 3.2 vs. 5.7 (P < .001), eversion 3.3 vs. 5.9 (P = .004), tension 2.9 vs. 5.9 (P = .001), leak tightness 3.2 vs. 5.7 (P = .005), iatrogenesis 6.9 vs. 7 (P = .47). The iatrogenesis parameter was not discriminatory, so it was removed from the tool. The total results were 12.5 for novices and 23.2 for experts (P = .001). The correlation between observers presented an intraclass correlation coefficient of 0.99 for the separation between stiches, 0.94 for eversion, 0.98 for tension and 0.99 for leak. The correlation between the score and the leak without pressure presented a Rosenthal's R of -0.71 (P < .001); with pressure R = -0.55 (P = .01). CONCLUSIONS The designed tool is valid to discriminate between novice and expert participants, presents very high concordance between observers and correlates with the risk of leak.

Purpose Acellular dermal matrices (ADM) are increasingly used in implant-based breast reconstruction (IBR). Uncertainty remains with regard to their efficacy and complications. The aim of this study was to evaluate the outcomes and complication rates associated with the use of ADMs in IBR. Methods Retrospective cohort study of patients undergoing ADM-assisted IBR between 2008 and 2013. Cases were identified from a prospectively collected database. Simple descriptive statistics and logistic regression analysis were performed. Results A total of 110 patients (175 mastectomies) were included in the analysis. The median age was 46 (19–75) years and the median BMI was 22.2 (16.2–41.5). Seventy nine mastectomies were performed for therapeutic purposes. The median mastectomy weight was 244 (185–335) gr. The majority of reconstructions were performed with fixed volume (n = 115, 66%) or permanent expandable implants (n = 53, 30%) as one-stage procedures. Forty mastectomies were associated with at least one complication. The infection rate was 2.3% (n = 4). Post-operative haematoma developed in 5 cases (2.9%), but only 2 required surgical interventions. Three mastectomies were complicated by nipple necrosis (3.6%), 3 with skin necrosis (1.7%) and 9 with wound dehiscence (5.1%). The capsule formation rate was 2.3% (n = 4). Reconstruction failure with implant loss occurred in 3 cases (1.7%). Conclusions The complication rates following ADM-assisted IBR can be very low with appropriate patient selection and meticulous surgical technique. This supports the safety of using ADM in carefully selected patients. Further research is warranted to assess the health economics of ADM use in IBR.

Objectives There are limited methods to identify which obese patients will experience wound complications after undergoing gynecologic surgery. We sought to determine the association between frailty and postoperative wound complications and to develop a prediction model for wound complications in this patient population. Methods We reviewed prospectively collected data of obese patients undergoing laparotomy though midline vertical incisions from 7/2013-3/2016. Modified frailty index (mFI) was calculated using 11 comorbidities previously validated. The primary outcome was the composite rate of postoperative wound complication. Data was analyzed using Fisher exact test or Chi-square and t-tests or Kruskal-Wallis tests. Poisson regression models were used to generate relative risks. Prediction models were created with receiver-operator characteristic curve analysis. Results Of 163 patients included, 56 (34%) were considered frail. Wound complications occurred in 52 patients (31.9%): 28 (50%) frail and 24 (22.4%) non-frail patients (RR 2.23, 95%CI 1.29-3.85). Frail patients had significantly greater frequencies of wound breakdown (37.5% vs 15%, RR 2.51, 95%CI 1.31-4.81). After controlling for BMI, tobacco use, and maximum postoperative glucose, frailty remained an independent predictor of wound complication (aRR 1.88, 95%CI 1.04-3.40). The area under the curve for the predictive model incorporating frailty was 0.73 for wound complications. Conclusion Frailty is associated with wound complications in obese patients undergoing gynecologic surgery via a midline vertical incision and is a useful tool in identifying the most high risk patients. Further prospective research is necessary to incorporate mFI into preoperative planning and counseling.

Background Microsurgical free tissue transfer is an important treatment option for nonhealing lower extremity diabetic wounds. The purpose of this study was to identify factors that affect flap survival and wound complications. Methods A retrospective review was conducted of 806 lower extremity free-flap reconstructions performed from 1979 to 2016. A total of 33 free flaps were used for coverage of nonhealing lower-extremity diabetic ulcers. Primary outcome measures were perioperative complications and long-term wound breakdown. Results The average age was 54 ± 12.3 y. 15.2% of patients were smokers, 12.1% had coronary artery disease and 12.1% had end-stage renal disease. Muscle flaps predominated (75.8%) compared to fasciocutaneous flaps (24.2%). There were 7 patients (21.2%) that underwent a revascularization procedure before (71.4%) or at the same time (28.6%) as the free flap. Immediate complications occurred in 7 flaps (21.2%) with 4 partial losses (12.1%) and 3 total flap failures (9.1%). Major wound complications occurred in 18.2% of patients. An end-to-side (E-S) anastomosis for the artery was used in 63.6% (n = 22) of flaps compared with an end-to-end (E-E) anastomosis. E-S anastomosis was associated with a significantly lower risk of wound complications compared with an arterial E-E anastomosis (0% versus 45.5%, P = 0.001). Conclusions The use of microvascular free flaps can be used successfully to cover lower-extremity diabetic wounds. E-E arterial anastomosis should be avoided if possible as it is associated with higher rates of wound breakdown, likely by impairing perfusion to a distal limb with an already compromised vasculature. Level of evidence Level III.

Background While the proportion of colon cancer occurring in older patients is expected to increase, these patients may have more complications that may lead to serious consequences. The aim of this study was assess postoperative complications and their short-term consequences in colon cancer surgery according to age. Patients and Methods Patients undergoing surgery for primary invasive colon cancer in 22 centers between June 2010 and December 2012 were included. Presurgical and surgical variables were analyzed, and in-hospital major postoperative complications and its most serious consequence (no relevant, transfusion, reintervention, admission to the intensive care unit, or death) were estimated according to age group. Chi-square tests were used to analyze the possible associations between variables and age groups. Results Data from 1976 patients, mean (range) age 68 (24-97) years, 62% men, were analyzed; 52.2% were aged > 69 years and 17.7% were aged > 79 years. The complication rate was 25.3%, reaching 30.9% in those aged ≥ 80 years. Older age was associated with a higher rate of postoperative infections during the hospital stay. The most common surgical complication in patients aged > 85 years was dehiscence of the anastomosis (11.5%). About 5% of patients with major complications died in the hospital (11.1% of those aged 80-84 years and 14.3% aged > 85 years). Among patients aged > 85 years, 38.1% required transfusions. Conclusion Older patients should receive appropriate functional preparation before the intervention, and when the risks of the intervention outweigh the potential benefits, a nonsurgical approach may be preferable.

The purpose of this study was to evaluate the association between smoking and postoperative complications following total shoulder arthroplasty. We hypothesized that active smokers would have significantly greater postoperative medical and surgical complications.The American College of Surgeons National Surgical Quality Improvement Program database was queried for patients who underwent total shoulder arthroplasties from 2005 through 2016. Patients were stratified based on tobacco use within the past year. Logistic regression was used to assess the relationship between smoking status and postoperative medical and surgical complications. Multivariate logistic regression was used to adjust for demographic and comorbid factors.We identified 14,465 patients, of whom 10.5% were active smokers. Smokers were more likely to be younger, to be female patients, and to have a lower body mass index compared with nonsmokers (P.001). Univariate analysis demonstrated that smoking was not associated with postoperative medical complications (P.05) but was associated with an increased risk of overall surgical complications (odds ratio [OR], 3.259; 95% confidence interval [CI], 1.861-5.709; P.001). Multivariate modeling showed that smoking increased the risk of wound complications (adjusted OR, 7.564; 95% CI, 2.128-26.889; P = .002) and surgical-site infections (adjusted OR, 1.927; 95% CI, 1.023-3.630; P = .042).This study demonstrates that smoking is associated with an increased risk of surgical complications following total shoulder arthroplasty. On the basis of our available data, medical complications are not significantly increased. This information can help risk stratify patients prior to their procedures.

Study Objective MONOFIX, a new absorbable barbed suture device, has a triangular stopper at the end to hold the suture to the tissue without hooking the looped end or knotting. The aim of this study was to compare the biomechanical strength and histologic features of MONOFIX with other barbed suture devices using a porcine model. Design Well-designed, controlled trial without randomization. Setting Animal laboratory in university hospital. Subjects Sixteen, 60-kg, mature female domestic pigs (skin closure group) and 5, 60-kg, mature female domestic pigs (fascial closure group). Interventions In the skin closure group, 3-0 MONOFIX versus 2 widely used 3-0 absorbable barbed sutures (3-0 V-Loc 180 or Stratafix). In the fascial closure group, 2-0 MONOFIX versus 1 widely used 2-0 absorbable barbed sutures (2-0 Stratafix). Measurements and Main Results In the skin closure group, the biomechanical wound strength of skin sutured with size 3-0 MONOFIX, V-Loc 180, or Stratafix was evaluated by postoperative day assessment (days 0, 3, 7, 14, and 28). In the fascial closure group, pigs underwent 2 paramedian incisions and were sutured with 2-0 MONOFIX or with 2-0 Stratafix to evaluate histologic reaction. At 6 weeks the tissues around the suture line were excised and microscopically evaluated. The biomechanical strength of the MONOFIX had similar tissue tensile strength compared with the control, regardless of postoperative day. In the fascial closure model, there was no significant difference in the average tissue reaction score between MONOFIX and Stratafix (1.2 ± .3 vs 1.3 ± .3, p = .478). Conclusion This study demonstrated that MONOFIX has equivalent tensile strength and histologic reaction when compared with commonly used barbed suture devices. Accordingly, this preclinical study suggests that the use of MONOFIX is a safe alternative to other barbed suture devices.

Study Objective To compare the rate of spontaneous and complete vaginal cuff dehiscence (VCD) using absorbable versus nonabsorbable sutures for vaginal cuff closure. Design Retrospective comparative cohort design. Setting Freestanding ambulatory surgery center in suburban Maryland. Patients Women age >18 years old who underwent hysterectomy for benign conditions between October 2013 and April 2018. Intervention Laparoscopic retroperitoneal hysterectomy was performed by 2 gynecologic surgical specialists. Transvaginal cuff closure was performed using either absorbable Vicryl (polyglactin 910) sutures (n = 881) or nonabsorbable Ethibond (polyester) sutures (n = 574). The nonabsorbable sutures were surgically removed after 90 days. Measurements and Main Results No statistically significant differences in age, race, weight, body mass index, parity, uterine weight, or number of comorbidities were noted between the nonabsorbable and absorbable suture groups. Spontaneous vaginal cuff dehiscence (VCD) occurred in 3 patients (0.52%) in the nonabsorbable group and in 12 patients (1.4%) in the absorbable group (p = .183). Eleven of the 12 cases of VCD in the absorbable group were precipitated by intercourse and occurred within 90 days of surgery. Conclusion Our data suggest that use of a nonabsorbable suture may be an effective approach to prevent spontaneous VCD, but the benefits should be weighed against the inherent risk associated with a second procedure to remove sutures.

Highlights • Vacuum-assisted closure is a well-established technical resource for treating complicated wounds. • In cases of suspicion of bone infection, VAC therapy is not enough to prevent bar removal. • Multiple surgical debridement sessions are mandatory before wound closure in cases of infection. • We present a case of surgical wound dehiscence with hardware exposure. • After VAC therapy and surgical debridement, the bilateral pectoralis muscle flap mobilization has been used., Introduction Multiple surgical debridement sessions are mandatory before wound closure in cases of infection after a modified Ravitch procedure for pectus excavatum. Vacuum-assisted closure (VAC) is a well-established technical resource for treating complicated wounds; however, in cases of suspicion of bone infection, this approach is not enough to prevent bar removal. Presentation of the case We present a case of surgical wound dehiscence with hardware exposure in a patient who had undergone chondrosternoplasty for pectus excavatum. Several sessions of debridement (three) and VAC were applied every time. The final result was achieved without the necessity to remove the hardware; however, to avoid the risk of infection, a bilateral pectoralis muscle flap mobilization was performed as the final step after the surgical wound revisions, although this approach is suggested to be used during the modified Ravitch procedure. This approach allows for a significant reduction in late complications and improves morphological outcomes. Discussion In summary, the pectoralis muscle flap transposition is very useful not only for aesthetical results but also in combination with multiple surgical revisions for conservative management in case of wound infection during a modified Ravitch procedure. In our case, this technique was adopted after accurate care of the wound and before the final closure, which helps to maintain good vascularization and a very satisfying result. Conclusion It is important to consider this approach during the modified Ravitch procedure, not only for better aesthetical results but also to prevent infections or wound dehiscence at the level of the bar.

Post-thoracotomy wound dehiscence after a lung transplant carries with it morbidity in the postoperative period. While this complication has been widely reported in the literature after a clamshell incision, the thoracotomy dehiscence's surgical solution has not received much emphasis. We present an original technical solution to deal with this complication, performed successfully in a 62-year-old woman diagnosed as having idiopathic pulmonary hemosiderosis after a single lung transplant. This surgical treatment consists of necrotic rib tissue removal, pleural effusion drainage, pulmonary adhesion removal, and chest wall defect reparation with bioabsorbable mesh. This operative technique results safe and effective for thoracotomy dehiscence reparation.

Purpose This study describes an incision-free minimally invasive conjunctival surgical (MICS) technique to repair late-onset leaking blebs after trabeculectomy. Methods A surgical technique to repair leaking blebs without incision or excision of conjunctiva is described. This is followed by retrospective review of all patients treated at the Glaucoma Unit at St. Michael's Hospital for bleb leaks repaired with MICS from 2012 to 2017. With Research Ethics Board approval, clinical data obtained from the charts included demographic information, vision, intraocular pressure (IOP) data before and after surgery, need for additional medication, and complications. Resolution of the bleb leak without the need for additional therapy or intervention for glaucoma control was considered a success. Results The MICS approach was applied to 14 eyes of 13 consecutive patients with a leaking bleb. Mean age of presentation was 70.2 ± 14.8 years, and all patients had a history of mitomycin use at the time of glaucoma surgery. The onset of bleb leak following trabeculectomy ranged from 7 months to 16.3 years. Mean pre-operative IOP was 4.5 ± 2.8 mm Hg; IOP measured 12.3 ± 3.0 mm Hg immediately after the procedure. Complete resolution of the bleb leak was observed following surgery in all cases. The follow-up period ranged from 2 weeks to 61 months (10.2 ± 18.1). Recurrent bleb leak was reported in 1 patient 2 years following initial surgery. In all cases, the initially repaired filtering blebs remained functional at last follow-up, and no additional medications were required. Conclusions The MICS procedure is an effective option for treating late-onset leaking blebs without cutting or excising conjunctival tissue. The minimal requirements of this method make it additionally accessible to low-resource settings. NOTE: Publication of this article is sponsored by the American Ophthalmological Society.

Purpose With the wide application of immunologic reconstitution treatment, such as hematopoietic stem-cell transplantation (HSCT), most patients of inflammatory bowel disease (IBD) with immunodeficiency owing to monogenic abnormalities need surgical intervention during the course of treatment, which is quite different from traditional IBD surgery. The aim of this study was to generalize the surgical strategies as a part of comprehensive therapy for these rare diseases. Methods A retrospective study was conducted based on the clinical data of children with immunodeficiency-derived IBD who underwent surgical treatment in Children's Hospital of Fudan University between January 2015 and December 2017. Results A total of 18 patients with monogenic abnormalities were enrolled. The major surgical indications included 11 cases of acute or chronic intestinal obstructions, 4 refractory intestinal infections, and 3 pneumoperitoneum, while 12 cases had perforations noted during intraoperative exploration. All of the patients underwent varieties of enterostomies to divert the affected or obstructed intestine during the primary surgery. Wound infections or dehiscence occurred in 7 patients, and 2 patients underwent reoperations for adhesive intestinal obstruction and prolapse. Postoperatively, 15 patients survived, 13 of which achieved immune reconstitution through subsequent HSCT or immunoglobulin supplementation. In the second-stage surgery, a posterior sagittal approach rectal resection was performed in 5 patients with complex anorectal complications. Twelve patients had undergone stoma closure procedures. Conclusion Surgical intervention should be performed earlier because the perforations are usually insidious in monogenic IBD. Preventative enterostomies are suggested in preparation for HSCT among patients with severe anorectal complications. Wound infections are the most common complication after the primary operation. Posterior sagittal rectal resection is a good option for patients with complex anorectal complications. Type of study Clinical research paper. Level of evidence Level IV.

Background Superficial wound dehiscence after total hip arthroplasty (THA) performed through the direct anterior approach (DAA) can be treated with superficial irrigation and debridement (I&D). The incidence and treatment of this complication has been described, but there are little data on the outcomes after a superficial I&D have not been described. The purpose of this paper was to examine the clinical outcomes of DAA THAs requiring postoperative superficial I&D. Methods A retrospective review of 1573 THAs performed using the DAA were identified utilizing a prospectively collected, single-institution joint registry. Of these 1573 cases, 18 THAs in 18 patients (1.1%) underwent a superficial I&D for superficial wound dehiscence. Outcomes studied included prosthetic joint infection (PJI) after superficial I&D, revisions, re-reoperations, complications, and clinical outcome scores. Results Survivorship from superficial I&D at 1, 2, and 5 years postoperatively was 98.6% at all time points. In the 18 patients who underwent superficial I&D, this was performed an average of 37 (range 12-83) days after their THA. Female gender (hazard ratio 5.5, 95% confidence interval 1.20-32.34, P = .0271) was associated with a higher risk of undergoing superficial I&D as was body mass index >30 kg/m2 (P = .0028), >35 kg/m2 (P 40 kg/m2 (P = .0037). At average follow-up of 2.2 (range 0.2-5.5) years, 0 patients developed PJI. Complications included femoral revision for a painful fibrously ingrown femoral component (1), pulmonary embolus (1), and death from respiratory failure (1). Postoperative Harris Hip Scores averaged score was 86.8 (range 57-99). Conclusions Superficial wound dehiscence requiring superficial I&D after DAA THA occurs in about 1%-2% of patients with low risk of subsequent PJI.

Background This study sought to identify risk factors associated with wound disruption following Caesarean section (CS) in women with class III obesity and to determine the value of individualized perioperative care plans in reducing its incidence. Methods The study included women with class III obesity who underwent CS after 24 weeks of gestation at Mount Sinai Hospital, Toronto, Ontario between 2011 and 2015 and collected data on demographics, clinical history, and perioperative details. Multivariable logistic regression analysis was performed to identify factors likely to contribute to a higher incidence of wound disruption (level of evidence II-3B). Results Of the 334 identified cases, in women with a mean BMI of 48.20 ± 7.52 kg/m2, there were 60 cases of wound disruption (18%). The most common perioperative interventions involved Pfannenstiel skin incisions (75.6%), subcutaneous tissue closure (65.4%), use of pressure dressings (65%), and thromboprophylaxis (71.8%). On bivariable analysis, surgical time >1 hour (24.2% vs. 13.5%; OR 2.03; P = 0.017) and the use of thromboprophylaxis (20.1% vs. 10.6%; OR 2.22, P = 0.031) were associated with increased wound disruption, but these associations were attenuated on multivariable regression analysis. Conclusions No single risk factor or perioperative intervention was independently associated with wound disruption. However, the use of individualized perioperative care plans resulted in fewer wound disruptions in our cohort when compared with published literature.

Objectives To assess the effect of monopolar coagulation vs cut mode during colpotomy at total laparoscopic hysterectomy on vaginal cuff dehiscence. Study design We conducted this randomized controlled trial at a university hospital’s department of obstetrics and gynecology from September 2016 through January 2018. Enrolled women were randomized 1:1 to monopolar coagulation or cut modes during colpotomy. We followed up 100 participants in the coagulation arm and 99 in the cut arm for ongoing data collection for 12 weeks after surgery. Exclusion criteria were suspicion of pregnancy, previous radiation therapy, uterine size exceeding 20 weeks’ gestation, contraindication for high intraabdominal pressure, clinical advanced stage malignant disease, and conversion to laparotomy before completion of colpotomy. Differences between groups for categorical variables were analyzed by chi-square test and the comparisons of continuous variables between groups were analyzed by Student’s t-test Results The study groups were comparable regarding demographics and perioperative parameters. The rate of vaginal cuff dehiscence in coagulation group (1%) was similar to that of cut group (0%) (p = 0.995). The other vaginal cuff related complication rates were also similar. Conclusion Monopolar coagulation and cut modes during colpotomy at total laparoscopic hysterectomy have similar vaginal cuff dehiscence rates and both energy modes seem acceptable for colpotomy.

Background Deep sternal wound infection remains a serious complication after cardiac surgery, leading to increased morbidity, mortality, and cost. The goal of our study was to develop a standardized, reproducible method to safely cover deep sternal wounds and ensure improved healing rates. Methods The study was developed as a retrospective cohort study. We included 58 patients who received standardized latissimus dorsi flap coverage of a sternum defect wound after poststernotomy mediastinitis at our institution between September 2015 and June 2017. Results The average age of the cohort was 66.75 years, and 51.72% of patients were men. The mean hospital stay was 26.83 days. Eight patients (14.75%) died during the hospital stay due to sepsis or heart failure. The average flap size was 137.13 cm2. The mean operative time was 155 minutes. Seventy-four percent of patients developed a seroma at the donor site, which was treated conservatively with compression garments and taps, and 7% of patients developed a wound dehiscence of the donor site, which was treated conservatively with dressings. The mean follow-up time was 15 weeks. All 50 surviving patients showed complete wound healing on follow-up. Conclusions The latissimus dorsi pedicled flap is a safe, reproducible technique for coverage of deep sternal wounds, with few relevant perioperative complications. By setting definite parameters for the flap dissection and by ensuring a reliable blood supply, our method enables the coverage of these complex wounds by an interdisciplinary team in any cardiovascular surgical setting.

The present study aimed to compare postoperative complications commonly revealed after sternotomy closure by new sternal ZipFix™ (Synthes GmbH, Oberdorf, Switzerland) implant and conventional steel wire.Among the initial 360 subjects, 326 patients enrolled in this randomised control trial who were candidates for cardiac surgery from April 2014 to March 2015. After the surgery, the sternal closure was randomly done with poly-ether-ether-ketone (PEEK) based sternal ZipFix (ZF) on the sternal body (n=168) or with conventional wires (CWs) (n=158). Patients were followed postoperatively as well as 1, 3, 6, and 12 months after discharge regarding postoperative complications such as pain severity, dehiscence, and infection including incisional infections (superficial or deep), and organ/space infection (mediastinitis or osteomyelitis).The mean age of the ZF and CW groups were 63.58±10.9 and 62.42±7.1years, respectively (p=0.262). In addition, there was no significant difference between the two groups' baseline characteristics (p0.05). Our study showed higher mean pain severity score in the conventional closure group compared with ZipFix closure group at all study time points (p0.001). Infection was seen in 2.76% of the overall participants with no significant difference of incisional and organ infection between the two groups throughout the study. After 1-month follow-up, five patients in the CW group had sternal dehiscence whereas no patients in ZF had dehiscence (p0.001).Our trial demonstrates greater clinical advantages in terms of pain and sternal dehiscence post surgery by using sternal ZipFix compared to conventional steel wire.

Sex has been known to significantly affect postoperative complications and length of stay after elective anterior cervical fusions. Current evidence on lumbar spine surgery is limited.The 2012-2016 American College of Surgeons National Surgical Quality Improvement Program database was queried using Current Procedural Terminology codes 22612, 22630, and 22633 to identify patients undergoing posterior lumbar fusions. A total of 23,615 patients were included in the final cohort.Out of 23,615 patients, 10,810 (45.8%) were men and 12,805 (54.2%) were women. After controlling for demographic, comorbidities-specific, preoperative, and operative differences between the 2 groups, female sex was found to be an independent risk factor significantly associated with a length of stay longer than 3 days (odds ratio [OR], 1.43; 95% confidence interval [CI], 1.35-1.51; P0.001), occurrence of any complication within 30 days (OR, 1.31; 95% CI, 1.16-1.47; P0.001), wound complications (OR, 1.43; 95% CI, 1.18-1.74; P0.001), urinary tract infections (OR, 2.25; 95% CI, 1.79-2.83; P0.001), 30-day reoperations (OR, 1.19; 95% CI, 1.02-1.39; P = 0.025), 30-day readmissions (OR, 1.16; 95% CI, 1.03-1.31; P = 0.015), and nonhome discharge (OR, 1.83; 95% CI, 1.69-1.98; P0.001). Interestingly, the only adverse outcome associated with male sex was renal complication (OR, 2.28; 95% CI, 1.43-3.65; P = 0.001).Contrary to literature on cervical fusions, we found that female sex was independently tied to an increased risk of adverse outcomes after elective posterior lumbar fusion. The results from the study suggest that women may benefit from close surveillance during the postoperative period to minimize risk of complications and subsequent resource utilization in this group.

Introduction The free anterolateral thigh (ALT) flap is a versatile reconstructive option for head and neck defects. Donor site complications are rare but severe; with wound dehiscence, need for secondary closure, and compartment syndrome reported. Objectives We propose prophylactic thigh fasciotomy as a surgical technique to facilitate primary closure while preventing donor site complications during ALT flap harvest. Methods We examined donor site wound characteristics, recipient site wound characteristics, and clinical outcomes for 24 consecutive ALT flaps performed for head and neck reconstruction from 2016 to 2018. All ALT donor sites underwent prophylactic fasciotomy. Results There were no incidents of thigh compartment syndrome or wound dehiscence of donor site; one patient underwent primary donor site skin grafting. Conclusion Prophylactic thigh fasciotomy allows mobilization of soft tissue to facilitate primary tension-free closure of the ALT donor site even for free flaps with a large skin component, while reducing the possibility of compartment syndrome.

Introduction The role that self-expanding stents play in the treatment of dehiscence after transthoracic esophagectomy is not well defined and controversial. Our aim is to describe the experience in a tertiary care hospital using these devices for treating dehiscence after Ivor Lewis esophagectomy. Methods Descriptive observational study of patients who suffered anastomotic dehiscence after a transthoracic esophagectomy, and especially those treated with stents, in the period between 2011 and 2016 at our hospital. Results Ten patients (11.8%) presented anastomotic dehiscence. Eight patients received stents, one of them died due to causes unrelated to the device. Stent migration was observed in one case, and the devices were maintained an average of 47.3 days. The stent was not effective only in one patient who suffered early dehiscence due to acute ischemia of the stomach. The two patients who did not receive stents died after reoperation. Conclusions Stents are safe and effective devices that did not associate mortality in our series. They are especially indicated in intermediate or late-onset dehiscence and in fragile patients. The use of stents, together with mediastinal and pleural drainage, avoid reoperations with morbidity and mortality. Therefore, stents should be part of the usual therapeutic arsenal for the resolution of most suture dehiscences after Ivor Lewis esophagectomy. Randomized prospective studies would help to more precisely determine the role played by these devices in the treatment of dehiscence after transthoracic esophagectomy.

Contains fulltext : 200454.pdf (Publisher’s version ) (Open Access) AIM: Wound dehiscence is a serious postoperative complication associated both with high morbidity and mortality. It has a significant rate of occurrence in breast reconstruction surgeries with a deep internal epigastric perforator (DIEP) and with a profunda artery perforator (PAP) flap. Risk factors for wound dehiscence include smoking, diabetes mellitus, chronic obstructive pulmonary disease, and obesity. The aim of this pilot study was to assess whether postoperative treatment with closed incision negative pressure therapy (ciNPT) decreases the incidence of donor site wound dehiscence in breast reconstruction patients. METHOD: Women undergoing a breast reconstruction with a DIEP or PAP flap were enrolled in a pilot randomized controlled trial and assigned treatment with either ciNPT or adhesive strips. The primary outcome was wound dehiscence upon follow-up after four weeks. Secondary outcomes that were evaluated included wound infection, pain, and allergy. There was no loss to follow-up. RESULTS: This pilot study included 51 women (n=25 ciNPT, n=26 adhesive strips). The two groups did not differ significantly in patients demographics or comorbidities. Wound dehiscence occurred in 11 patients (n=2 ciNPT, n=9 adhesive strips). This difference was statistically significant: p=0.038. There were no statistically significant differences in secondary outcomes between the two groups. CONCLUSION: In this pilot study, postoperative treatment with ciNPT decreased the incidence of donor site wound dehiscence in breast reconstruction patients. Further research is ongoing by the same hospital. This trial was registered in the Netherlands Trial Register (NTR) under ID no. NTR5808.

Objective To assess the effectiveness of subcutaneous saline irrigation in preventing wound complications after cesarean sections. Study design Patients undergoing primary cesarean sections were randomly assigned to either the subcutaneous saline irrigation group or the control group. The participants were asked to come to the hospital for routine inspection of the skin incision on day 7 and day 30 postoperatively. The wounds were inspected for hematoma, seroma, separation and signs of superficial infection. The prime outcome was the comparison of the superficial surgical site infection (SSI) rates among the groups. Additionally, factors associated with wound complications were also analyzed using logistic regression. Results A total of 204 women undergoing primary cesarean sections were randomized, and 185 were included in the final analysis. There was no significant difference in terms of SSI rates among the groups (14.3% in the saline group vs 12.8% in the control group, p = 0.76). However, the existences of hematoma and seroma were significantly lower in the saline irrigation group compared to the control group. Conclusion Irrigation of subcutaneous tissue decreases the occurrences of both postoperative hematoma and seroma in women undergoing primary cesarean sections.

Background Traditionally, wire cerclage has been used to reapproximate the sternum after sternotomy. Recent evidence suggests that rigid plate fixation for sternal closure may reduce the risk of sternal complications. Methods The Medline and Embase databases were searched from inception to February 2017 for studies that compared rigid plate fixation with wire cerclage for cardiac surgery patients undergoing sternotomy. Random effects meta-analysis compared rates of sternal complications (primary outcome, defined as deep or superficial sternal wound infection, or sternal instability), early mortality, and length of stay (secondary outcomes). Results Three randomized controlled trials (n = 427) and five unadjusted observational studies (n = 1,025) met inclusion criteria. There was no significant difference in sternal complications with rigid plate fixation at a median of 6 months' follow-up (incidence rate ratio 0.51, 95% confidence interval [CI]: 0.20 to 1.29, p = 0.15) overall, but a decrease when including only patients at high risk for sternal complications (incidence rate ratio 0.23, 95% CI: 0.06 to 0.89, p = 0.03; two observational studies). Perioperative mortality was reduced favoring rigid plate fixation (relative risk 0.40, 95% CI: 0.28 to 0.97, p = 0.04; four observational studies and one randomized controlled trial). Length of stay was similar overall (mean difference −0.77 days, 95% CI: −1.65 to +0.12, p = 0.09), but significantly reduced with rigid plate fixation in the observational studies (mean difference −1.34 days, 95% CI: −2.05 to −0.63, p = 0.0002). Conclusions This meta-analysis, driven by the results of unmatched observational studies, suggests that rigid plate fixation may lead to reduced sternal complications in patients at high risk for such events, improved perioperative survival, and decreased hospital length of stay. More randomized controlled trials are required to confirm the potential benefits of rigid plate fixation for primary sternotomy closure.

Summary Background The incidence of vulvar cancer is increasing, but surgical treatment—the current standard of care—often leads to unsatisfactory outcomes, especially in patients with node-positive disease. Preliminary results at our centre showed that locoregional spread of vulvar carcinoma occurs within tissue domains defined by stepwise embryonic and fetal development (ontogenetic cancer fields and associated lymph node regions). We propose that clinical translation of these insights into practice could improve outcomes of surgical treatment of vulvar cancer. Methods We did a single-centre prospective trial at the University of Leipzig's Cancer Center. Eligible patients were aged 18 years or older, had ontogenetic stage 1–3b histologically proven primary carcinoma of the vulva, and had not undergone previous surgical or radiotherapy treatment for vulvar cancer or any other major perineal or pelvic disease. In view of staged morphogenesis of the vulva from the cloacal membrane endoderm at Carnegie stage 11 to adulthood, we defined the tissue domains of tumour spread according to the theory of ontogenetic cancer fields. On the basis of ontogenetic staging, patients were treated locally with partial, total, or extended vulvar field resection; regionally with therapeutic inguinopelvic lymph node dissection; and anatomical reconstruction without adjuvant radiotherapy. The primary endpoints were recurrence-free survival, disease-specific survival, and early postoperative complications. Analysis of tumour spread and early postoperative surgical complications was done by intention to treat (ie, all patients were included), whereas outcome analyses were done per protocol. This ongoing trial is registered with the German Clinical Trials Register, number DRKS00013358. Findings Between March 1, 2009, and June 8, 2017, 97 consecutive patients were included in the study, of whom 94 were treated per protocol with vulvar field resection, therapeutic inguinopelvic lymph node dissection, and anatomical reconstruction without adjuvant radiotherapy. 46 patients had moderate or severe postoperative complications, especially infectious perineal and inguinal wound dehiscence. 3-year recurrence-free survival in all patients was 85·1% (95% CI 76·9–93·3), and 3-year disease-specific survival was 86·0% (78·2–93·8). Interpretation Our results support the theory of ontogenetic cancer fields for vulvar carcinoma, accord with our previous findings in cervical cancer, and suggest the general applicability of the theory. Application of the concept of cancer field resection could improve outcomes in patients with vulvar carcinoma, but needs to be investigated further in multicentre randomised controlled trials.

The objective of our study was to compare length of stay and wound complications after hybrid robotic transversus abdominis release (hrTAR) vs. robotic transversus abdominis release (rTAR) Two cohorts of patients undergoing robotic (rTAR) and hybrid robotic (hrTAR) performed by two surgeons at a single institution were analyzed. Mean length of stay (LOS) and incidence of surgical site occurrences (SSO) were compared. 57 patients undergoing rTAR and 25 patients undergoing hrTAR were analyzed. The hrTAR group had larger mean hernia dimensions and a larger proportion of men but otherwise the patient cohorts were similar. LOS was not statistically different between rTAR and hrTAR (2.8 vs 3.7 days p = 0.06). We found no difference in incidence of surgical site occurrences between the two groups (7.0% vs 4.0% p = 0.52). Hybrid robotic assisted TAR allows for repair of complex ventral hernias with similar lengths of stay and wound morbidity to pure robotic repairs.

Purpose: To evaluate the effect of retention sutures on abdominal pressure and postoperative prognosis in abdominal surgery patients. Methods: This prospective cohort study included patients who were admitted to Daping Hospital from May 15, 2014 to October 11, 2014. A total of 57 patients were enrolled, including 18 patients in the "U" type retention suture group, 17 patients in the intermittent retention suture group, and 22 patients in non-retention suture group. The demographic data, clinical data and risk factors for abdominal wound dehiscence were recorded. The bladder pressure (IVP) was monitored preoperatively, intraoperatively, and four days postoperatively. Additionally, the incidence of abdominal wound dehiscence and infection 14 days after the operation was recorded. Results: During the operation, the IVP decreased and then increased; it was at its lowest 1 h after the start of the operation (5.3 mmHg ± 3.2 mmHg) and peaked after tension-reducing (8.8 mmHg ± 4.0 mmHg). The IVP values in the "U" type retention suture group and intermittent retention suture group were higher than in the non-retention suture group 4 days after operation (p < 0.005). The Visual Analogue Scale (VAS) pain scores were 3.9 ± 2.2, 3.8 ± 2.0, and 3.0 ± 1.0 in the retention suture group, intermittent retention suture group and non-retention suture group, respectively. The VAS pain scores in the "U" type tension-reducing group and intermittent tension-reducing group were higher than in the non-tension-reducing group (p < 0.005). Conclusion: Although retention sutures may reduce the incidence of postoperative wound dehiscence in abdominal surgery patients, they can increase the IVP and postoperative pain.

Background The purpose of this study was to compare the posterior approach (PA) with the direct anterior approach (DAA) among obese and nonobese total hip arthroplasty patients to determine if obese DAA patients have a higher risk of infection or wound complications compared with obese PA patients. Methods We retrospectively evaluated 4651 primary total hip cases performed via anterior approach or PA between 2009 and 2015. Patients were divided into 4 study groups based on approach and body mass index (BMI): (1) DAA Results The rate of deep infection in groups 1 and 3 (nonobese anterior vs posterior) was 0.28% and 0.36%, respectively (P = .783); and in groups 2 and 4 (obese anterior vs posterior) was 2.35% and 2.7%, respectively (P = .80). The rate of wound complications between groups 1 and 3 (nonobese) was 1.0% and 0.3%, respectively (P = .005). Between groups 2 and 4 (obese), the rates of complications were 1.7% and 1.4%, respectively (P = 1.0). There was no difference in reoperation rates for wounds between groups 1 and 3 or between groups 2 and 4 (P = .217, P = .449). Conclusion In the largest available series, there was no difference in deep infection rates between the 2 approaches. In the subset of obese patients with BMI ≥35 kg/m2, there was no increased risk of deep infection or wound complications in DAA patients compared with PA patients. However, anterior hip cases experienced higher rates of superficial wound complications compared with posterior cases across all BMIs.

An isthmocele appears as a fluid pouchlike defect in the anterior uterine wall at the site of a prior cesarean section and ranges in prevalence from 19% to 84%, a direct relation to the increase in cesarean sections performed worldwide. Many definitions have been suggested for the dehiscence resulting from cesarean sections, and we propose standardization with a single term for all cases-isthmocele. Patients are not always symptomatic, but symptoms typically include intermittent abnormal bleeding, pain, and infertility. Pregnancy complications that result from an isthmocele include ectopic pregnancy, low implantation, and uterine rupture. Magnetic resonance imaging and transvaginal ultrasound are the gold standard imaging techniques for diagnosis. Surgical treatment of an isthmocele is still a controversial issue but should be offered to symptomatic women or the asymptomatic patient who desires future pregnancy. When surgery is the treatment choice, laparoscopy guided by hysteroscopy, hysteroscopy alone, or vaginal repair are the best options depending on the isthmocele's characteristics and surgeon expertise.

Aqueous drainage devices play an important role in the treatment of refractory glaucomas; however, they can be associated with early and late postoperative complications, including conjunctival dehiscence, which must be repaired surgically. Recurrent dehiscence despite surgical repair is uncommon and can be sight threatening. We discuss possible causes and management options of recurrent conjunctival dehiscence in a 2-year-old and the role of oral doxycycline and azithromycin in its management.

Objective The aim is to present a case series that illustrates possible benefits from combining minimally invasive plate osteosynthesis (MIPO), plastic surgery and antibiotic therapy, in order to treat and eradicate infection in patients with tibial pilon or calcaneal fractures. Methods Eleven consecutive patients with dehiscence of the surgical wound in outcomes MIPO using a Locking Compression Plate (LCP) for tibial pilon, or calcaneus fractures. The patients had developed a documented infection of the surgical wound. All patients were treated and followed-up by the multidisciplinary team with the orthopedic surgeon, the plastic surgeon and the infectious disease physician. All patients were followed by the plastic surgeon to treat the wound dehiscence, as well as by the orthopedic surgeon until fracture consolidation. The duration of the antibiotic therapy was from 4 to 6 months. After 6 weeks, the intravenous treatment was replaced by oral administration. The follow-up intervals were 15 days, 40 days, and 3 months. Results The average time of wound closure was 109 ± 60 days. The antibiotics used were chosen according to the antibiogram. The antibiotic therapy had a duration of 4–6 months, and after 6 weeks, the therapy switched to oral administration. At the 3-month follow-up, all patients had excellent outcomes and had returned to their normal activity of daily living. Conclusion The patients in this study responded positively to a combination of MIPO, plastic surgery and antibiotic therapy, confirming that multidisplinary treatment in association with titanium devices are able to eradicate infection in short time.

The objective of this study was to characterize post-operative outcomes of chemical castration as compared to surgical castration performed by existing municipal field clinics. Fifty-four healthy adult male dogs underwent chemical castration with zinc gluconate solution and 55 healthy adult male dogs underwent surgical castration in veterinary field clinics. Dogs in each group were evaluated for swelling, inflammation, and ulceration (chemical castration) or dehiscence (surgical castration) at Days 3, 7, and 14 following castration. More surgically castrated dogs required medical intervention than chemically castrated dogs (P=0.0328); the number of dogs requiring surgical repair within each group did not differ (P=0.3421). Seven chemically castrated dogs and 22 surgically castrated dogs experienced swelling, inflammation, and/or ulceration; all were managed medically. Two chemically castrated dogs experienced scrotal ulceration requiring surgical castration at Days 3 and 7. One surgically castrated dog experienced partial incisional dehiscence requiring surgical repair at Day 3. Our results suggest that chemical castration of dogs in field clinics is a feasible alternative to surgical castration, but proper follow-up care should be ensured for at least 7days post-procedurally.

Background Compromised wound healing in cranio-maxillo-facial surgery is a threat to the patient's rehabilitation. Therapy of chronic and/or infected wounds is time- and cost-consuming, burdensome and occasionally futile. Cold atmospheric plasma is a new approach that promises to overcome these limitations. The aim of this proof-of-concept study was to evaluate the clinical outcome of cold plasma irradiation in patients with impaired wound healing who are refractory to conservative wound therapy and/or revision surgery. Materials and methods We enrolled six patients (mean age: 63.5 years; SD 8.8 years; 1 female and 5 males) who experienced various cranio-maxillo-facial surgical procedures and suffered from wound healing disturbances. In addition to established wound care, all wounds were irradiated with cold atmospheric plasma. The primary outcome variable was the attainment of complete wound closure. Results In all patients, complete remission in terms of wound closure was observed within a mean time of 15.5 weeks (range: 4–38 weeks). No undesirable side effects were observed, and no inflammation or infection occurred after cold plasma initiation. Conclusion The use of cold atmospheric plasma might offer a reliable, conservative treatment option in complicated wound healing disturbances in cranio-maxillo-facial surgery.

Background Superficial wound complications occur in up to 10% of total knee arthroplasty (TKA) procedures and have been associated with periprosthetic joint infection. The ideal material for TKA closure should offer: 1) fast intraoperative application, 2) minimal wound complications and 3) removable by patients without assistance. We evaluated a novel, non-invasive, removable skin closure system for TKA to determine its effect on wound complications. Methods We prospectively evaluated 221 consecutive TKA patients who received skin closure using a non-invasive zipper-like system (‘Zip’; Zip 16 Surgical Skin Closure System; Zipline Medical). All procedures were performed by a single surgeon using the mini-midvastus approach. Patients received two weeks of rivaroxaban postoperatively. Demographics, comorbidities, in-hospital complications and six-week wound evaluation were recorded. Data was compared to a cohort of 1001 patients from the same surgeon who received staples for closure and coumadin for thromboprophylaxis. Results Zip patients had a significantly higher BMI (p = 0.001), incidence of diabetes (p = 0.035) and smoking (p = 0.005). Zip patients removed dressings themselves and did not report problems with dressing care. Rate of readmission for wound-related complications was significantly lower in the Zip closure group (p = 0.045). Overall readmission rates were similar between groups. Conclusions In our experience, the Zip 16 Surgical Skin Closure System is easy to apply, avoids home care and has produced fewer wound complications compared to staples. Results have been positive despite the study cohort having a higher number of diabetic patients and using an anticoagulant associated with a higher risk of wound complications.
