The clinical applications of D-type parastomal hernia repair surgery.

OBJECTIVE: This study investigated the use of a modified laparoscopic repair of paraostomy hernia technique, called "D-Type parastomal hernia repair surgery" which combines abdominal wall and extraperitoneal stoma reconstruction, in patients with parastomal hernia (PSH) following colorectal stoma surgery. The aim was to determine whether D-type parastomal hernia repair surgery is a promising surgical approach compared to the traditional laparoscopic repair technique (Sugarbaker method) for patients with PSH. METHODS: PSH patients were selected and retrospectively divided into two groups: the study group underwent D-type parastomal hernia repair, while the control group underwent laparoscopic Sugarbaker repair. Clinical data from both groups were analyzed. RESULT: Compared to control group (n = 68), the study group undergoing D-type stoma lateral hernia repair had significant increase in total operative time (98.82 ± 12.37 min vs 124.61 ± 34.99 min, p < 0.001). The study group also showed better postoperative stoma bowel function scores in sensory ability, frequency of bowel movements, and clothing cleanliness without a stoma bag (p = 0.037, 0.001, 0.002). The treatment cost was significantly higher in the control group (3899.97 ± 260.00$ vs 3215.91 ± 230.03$, p < 0.001). The postoperative recurrence rate in the control group was 26.4%, while in the study group, it was 4.3%, with a significant statistical difference (p = 0.024). In terms of long-term postoperative complications, the study group had an overall lower incidence compared to the control group (p = 0.035). Other parameters showed no significant differences between the two groups. CONCLUSION: The study suggests that D-type parastomal hernia repair surgery is a safe and feasible procedure. Compared to traditional surgery, it can reduce the recurrence of lateral hernia, improve postoperative stoma bowel function, and save medical resources.

Open retromuscular keyhole compared with Sugarbaker mesh for parastomal hernia repair: Early results of a randomized clinical trial.

BACKGROUND: Open parastomal hernia repair can be performed using retromuscular synthetic mesh in a keyhole or Sugarbaker configuration. Relative morbidity and durability are unknown. Here, we present perioperative outcomes of a randomized controlled trial comparing these techniques, including 30-day patient-reported outcomes, reoperations, and wound complications in ≤90 days. METHODS: This single-center randomized clinical trial compared open parastomal hernia repair with retromuscular medium-weight polypropylene mesh in the keyhole and Sugarbaker configuration for permanent stomas between April 2019 and April 2022. Adult patients with parastomal hernias requiring open repair with sufficient bowel length for either technique were included. Patient-reported outcomes were collected at 30 days; 90-day outcomes included initial hospital length of stay, readmission, wound morbidity, reoperation, and mesh- or stoma-related complications. RESULTS: A total of 150 patients were randomized (75 keyhole and 75 Sugarbaker). There were no differences in length of stay, readmission, reoperation, recurrence, or wound complications. Twenty-four patients (16%) required procedural intervention for wound morbidity. Ten patients (6.7%) required abdominal reoperation in ≤90 days, 7 (4.7%) for wound morbidity, including 3 partial mesh excisions (1 keyhole compared with 2 Sugarbaker; P = 1). Four mesh-related stoma complications requiring reoperations occurred, including stoma necrosis (n = 1), bowel obstruction (n = 1), parastomal recurrence (n = 1), and mucocutaneous separation (n = 1), all in the Sugarbaker arm (P = .12). Patient-reported outcomes were similar between groups at 30 days. CONCLUSION: Open parastomal hernia repair with retromuscular mesh in the keyhole and Sugarbaker configurations had similar perioperative outcomes. Patients will be followed to determine long-term relative durability, which is critical to understanding each approach's risk-benefit ratio.

Mesh versus suture repair of incisional hernias 2 cm or less: Is mesh necessary? A propensity score-matched analysis of the abdominal core health quality collaborative.

BACKGROUND: Mesh has been the acceptable standard for incisional hernia repair regardless of hernia size. It is not clear whether there is a size of incisional hernias in whom repair would be best performed without mesh. This study aims to compare outcomes of mesh versus suture repairs for incisional hernias <2 cm in size. METHODS: Incisional hernia repairs from 2012 to 2021 for hernias ≤2 cm in width were queried from the Abdominal Core Health Quality Collaborative. Those with 1-year follow up were considered. Hernia recurrence was defined using composite hernia recurrence, which combines both clinical and patient reported outcomes. Propensity score matching was performed between mesh and non-mesh using body mass index, smoking, diabetes, and drains as covariates. RESULTS: A total of 352 patients met inclusion criteria. After propensity score matching, there were 132 repairs with mesh and 71 without. There was no difference in recurrence rates at 1 year between mesh and non-mesh repairs (15% vs 24%, P = .12). Mesh was associated with a higher rate of 30-day postoperative complications (11% vs 1%, P = .017). There were no differences in 1-year quality of life scores. CONCLUSION: The repair of incisional hernias ≤2 cm without mesh results in similar recurrence rates, similar quality of life scores, and lower postoperative early complications compared with repairs with mesh. Our findings suggest that there may be select patients with small incisional hernias that could reasonably undergo incisional hernia repair without mesh. Longer-term follow-up is needed to confirm ideal candidates and durability of these repairs.

[Incisional hernia: open abdominal wall reconstruction. Current state of the technique and results]. / Narbenhernien: offene Operationsverfahren und Ergebnisse einer Kohortenstudie mit 343 Patienten.

The treatment of complex midline hernias remains a particular challenge. The currently refined knowledge of the anatomy in the cadaver laboratory and advancing clinical experience have changed our present approach. The aim of this review is to present a description of the updated surgical procedures and outcomes. We favor the retromuscular or preperitoneal layer for mesh implantation, including the Rives-Stoppa procedure (sublay mesh) and posterior component separation with the Madrid modification. We operated on 334 complex midline incisional hernias: 6.3% retromuscular preperitoneal, 15% after Rives-Stoppa, 2.4% anterior component separation and 76% posterior component separation. A bridging procedure was used in 31%. A complication occurred in 35.3%, most of which were wound healing disorders (SSO). The average length of hospital stay was 7.2 days. We recorded a very low incidence of long-term complications: 3.3% recurrence, 0.9% chronic pain (daily use of pain medication), 6% bulging, 1.8% chronic seroma and 2.6% chronic mesh infection. Despite the associated morbidity, retromuscular/preperitoneal treatment offers excellent long-term results.

Pregnancy complicated by massive incisional hernia: challenges in management and review of literature.

Pregnancy complicated by incisional hernia is rare but can become an obstetric challenge if the gravid uterus becomes displaced or incarcerated into the hernial sac or if there is ulceration of the overlying dermis as a result of increased intra-abdominal pressure being transmitted to the skin. We report a case of a pregnant woman presenting with a large incisional hernia at 19 weeks of gestation and discuss how problems encountered with progressing pregnancy were managed conservatively by adopting a multidisciplinary team approach (which included surgeons and radiologists). She underwent a caesarean section at 35 weeks of gestation due to active bleeding from the ulcerated skin and foetal growth restriction with subsequent staged secondary hernia repair at a tertiary centre. Close surveillance is mandatory, and a decision on the mode and timing of delivery as well as when to perform the surgical repair of the fascial defect should be team based.

Acute appendicitis within an incisional hernia: a type of Amyand's hernia.

A man in his 60s presented to the emergency department with generalised abdominal pain and distention associated with the inability to pass stool or gas. The patient had undergone a laparoscopic partial right nephrectomy due to renal cell carcinoma a year ago. The workup diagnosis suggested an incarcerated incisional hernia. Surgical treatment was proposed. Intraoperatively, we found an ileocecal appendix with a macroscopically gangrenous appearance inside the hernia sac. An appendectomy was performed, and the hernia defect was closed using a tension repair. Amyand's hernia, a rare condition, is classically described as an inguinal hernia containing the appendix, but it can also refer to an incisional hernia containing the appendix. Amyand's hernia classification depends on the localisation of the hernia sac and its contents, including the presence or absence of appendix inflammation.This case report described a patient with Amyand's hernia, which was diagnosed intraoperatively. The treatment was also discussed including open appendectomy and primary repair of the defect using a tension repair approach.

Analysis of recurrence and risk factors in laparoscopic sandwich technique for parastomal hernia repair.

INTRODUCTION: Parastomal hernias are frequent and highly recurrent. The sandwich technique is a combination of the keyhole and Sugarbaker techniques, using a double intraperitoneal mesh. The objective of this study was to assess the outcomes of the sandwich technique, specifically focusing on recurrence rates. MATERIALS AND METHODS: Observational retrospective study conducted in two tertiary referral centers in Catalonia, Spain. All consecutive patients who underwent parastomal hernia repair using the sandwich technique between 1st January 2016 and 31st December 2021 were included. RESULTS: A total of 38 patients underwent the laparoscopic sandwich technique for parastomal hernia repair. The overall recurrence rate was 7.9% (3/38), with a median follow-up of 39 months (IQR: 12.3-56.5). According to the EHS classification for parastomal hernia, there were 47.4% (18/38) type I defects, 10.5% (4/38) type II defects, 28.9% (11/38) type III defects, and 13.2% (5/38) type IV defects. The used mesh was predominantly TiMesh® (76.3%; 29/38), followed by DynaMesh® IPOM (23.7%; 9/38). Patients with recurrence exhibited higher rates of seroma, hematoma, surgical site infection, and one case of early recurrence attributed to mesh retraction. Consequently, postoperative complications emerged as the primary risk factor for hernia recurrence. CONCLUSION: The sandwich technique demonstrated recurrence rates consistent with those reported in the existing literature.

Single-staged retromuscular abdominal wall reconstruction with mesh at the time of ostomy reversal: are we crossing the line? An ACHQC Analysis.

INTRODUCTION: The most appropriate method of reconstructing the abdominal wall at the site of a simultaneous stoma takedown is controversial. The contaminated field, concomitant GI procedure being performed and presence of a hernia all complicate decision-making. We sought to describe the surgical approaches, mesh type and outcomes of concomitant abdominal wall reconstruction during stoma takedown in a large hernia registry. METHODS AND PROCEDURES: All patients who underwent stoma takedown with simultaneous hernia repair with retromuscular mesh placement from January 2014 to May 2022 were identified within the Abdominal Core Health Quality Collaborative (ACHQC). Patients were stratified by mesh type including permanent synthetic (PS), resorbable synthetic (RS) and biologic mesh. Association of mesh type with 30-day wound events and other complications and 1-year outcomes were evaluated. RESULTS: There were 368 patients who met inclusion criteria. Eighty-nine patients had ileostomies, 276 colostomies and 3 had both. Two hundred and seventy-nine (75.8%) patients received PS mesh, 46 (12.5%) biologic, and 43 (11.7%) RS. Seventy percent (259/368) had a parastomal hernia, 75% (285/368) had a midline incisional hernia, and 48% (178/368) had both. All groups had similar preoperative comorbidities and the majority had a transversus abdominus release. All mesh groups had similar thirty-day SSI (13.2-14.3%), SSO (10.5-17.8%) and SSOPI (7.9-14.1%), p = 0.6. Three patients with PS mesh developed infected synthetic mesh and one PS mesh required excision. Four patients with PS developed an enterocutaneous fistula. Of these, only one patient was recorded as having both an enterocutaneous fistula and mesh infection. Thirty-day reoperation and readmission were similar across all mesh groups. Recurrence at 1-year was similar between mesh groups. Quality of life measured using HerQLes scores were higher at one year compared to baseline in all groups indicating improvement in hernia-specific quality of life. CONCLUSION: Early complication rates associated with simultaneous stoma takedown and abdominal wall reconstruction are significant, regardless of mesh type utilized. Concomitant surgery should be weighed heavily and tailored to individual patients.

The same parastomal hernia repairs rate in the different approaches to colostomy.

PURPOSE: This study aimed to compare the parastomal hernia repairs rate in the different approaches to colostomy and investigate the risk factors for parastomal hernia formation in patients with permanent colostomies. METHODS: Consecutive rectal cancer patients who underwent abdominoperineal resection from June 2014 to July 2020 in West China Hospital were divided into two groups according to their surgical approach for permanent colostomies. The impact of different approaches to colostomy on parastomal hernia repairs was determined by comparing a group of patients receiving an extraperitoneal route to colostomy with a group receiving transperitoneal. Potential variables were evaluated first with univariate and then multivariate analyses to identify the risk factors for the formation of parastomal hernia. RESULTS: Two hundred two subjects in the transperitoneal group and 103 in the extraperitoneal group attended the follow-up visit with a median follow-up period of 33 (25th-75th percentiles, 17-46) months. Clinically and radiologically detectable parastomal hernias were present in 76 of 202 (37.6%) and 14 of 103 (13.6%) subjects in the transperitoneal and extraperitoneal groups during the follow-up period (p＜0.01). Besides, 10 of 76 (13.1%) subjects in the transperitoneal group and 2 of 14 (14.3%) subjects in the extraperitoneal group underwent a parastomal hernia operation during the follow-up (p = 0.82). In addition, the transperitoneal approach of colostomy (p = 0.002), older age (p＜0.001), and higher body mass index (p = 0.013) were identified as independent risk factors for the occurrence of parastomal hernia. CONCLUSIONS: Extraperitoneal colostomy decreased the detectable parastomal hernias but did not reduce the surgical repair rate of parastomal hernias.

Sarcopenia and body fat change as risk factors for radiologic incisional hernia following robotic nephrectomy.

OBJECTIVE: To assess the effect of body muscle and fat metrics on the development of radiologic incisional hernia (IH) following robotic nephrectomy. MATERIALS AND METHODS: We retrospectively reviewed the records of patients who underwent robotic nephrectomy for kidney tumors between 2011 and 2017. All pre- and postoperative CTs were re-reviewed by experienced radiologists for detection of radiologic IH and calculation of the following metrics using Synapse 3D software: cross-sectional psoas muscle mass at the level of L3 and L4 as well as subcutaneous and visceral fat areas. Sarcopenia was defined as psoas muscle index below the lowest quartile. Cox proportional hazard model was constructed to examine the association between muscle and fat metrics and the risk of developing radiologic IH. RESULTS: A total of 236 patients with a median (IQR) age of 64 (54-70) years were included in this study. In a median (IQR) follow-up of 23 (14-38) months, 62 (26%) patients developed radiologic IH. On Cox proportional hazard model, we were unable to detect an association between sarcopenia and risk of IH development. In terms of subcutaneous fat change from pre-op, both lower and higher values were associated with IH development (HR (95% CI) 2.1 (1.2-3.4), p = 0.01 and 2.4 (1.4-4.1), p < 0.01 for < Q1 and ≥ Q3, respectively). Similar trend was found for visceral fat area changes from pre-op with a HR of 2.8 for < Q1 and 1.8 for ≥ Q3. CONCLUSION: Both excessive body fat gain and loss are associated with development of radiologic IH in patients undergoing robotic nephrectomy.

Early experience with robotic central pancreatectomy with patient-reported outcomes and comparison with open central pancreatectomy.

BACKGROUND: Robotic central pancreatectomy (CP) has emerged in recent years as a noninferior approach to open CP and may offer improved patient-reported outcomes and reduction in incisional hernias. METHODS: All patients who underwent open and robotic CP between (2013 and 2022) were selected, and perioperative outcomes were analyzed. Patients who underwent robotic CP were interviewed over the phone to assess patient-reported postoperative outcomes. RESULTS: A total of 18 CP operations (56%-open vs. 44%-robotic) were identified. The overall median age was 67 years (interquartile range: 60-72), and 50% (n = 9) of patients were female. Median length of surgery was statistically longer for robotic CP (411 vs. 138 min, p = 0.002); all other intraoperative variables were similar. Postoperatively, a similar number of patients in the open and robotic cohorts developed clinically significant postoperative pancreatic fistulas (37.5% vs. 30%, p = 1) and major complications (37.5% vs. 20%, p = 0.60), respectively. No patients in the robotic cohort developed an incisional hernia, compared to 40% (n = 4) in open (p = 0.08). All patients returned to a baseline level of activity and reported a high quality of life. CONCLUSION: With the exception of longer operative times, robotic CP is a noninferior, definitive resection technique for select lesions of the middle pancreas. Additionally, the robotic approach may result in a reduction in incisional hernia development.

'Flip-flap' hernia sac sandwich mesh hernioplasty for giant incisional hernia.

Purpose: The treatment of giant ventral hernia (GVH) with domain loss is a challenge for surgeons. This modified and simplified form of sandwich technique in a form of flip-flap repair was done to assess the outcomes of GVH repair by using the hernia sac taking into account the late complications in terms of recurrence, mesh explantation and early: SSO (surgical site occurrence). Material and method: A total of 21 patients of GVH were treated with flip-flap repair technique in the department of surgery in a teaching hospital in the central India between December 16 to June 21. In flip-flap technique the hernia sac is tailored in the best possible way, by making multiple layered flaps encasing the Polypropylene mesh in between, separating it from intraperitoneal contents and subcutaneous tissue. Results: In this prospective and interventional study, the collected data revealed the mean follow up period of 22.3 months (7months to 48months). Mean age was 44.2years (27-65 years). SSO was seen in 38% of cases mainly in the form of SSI. No explantation of mesh and recurrence was seen in any patient. Conclusion: The flip-flap repair technique is safe and effective surgical technique that can be used for the treatment of GVH regardless of the size, BMI or position of hernia.

A Novel Robotic Approach for the Repair of Abdominal Wall Hernias With Concomitant Diastasis Recti: Outcomes and Long-term Follow-up.

BACKGROUND: Diastasis recti (DR) is defined as the separation of the rectus muscles as a result of the linea alba thinning and stretching. The purpose of this study was to evaluate the long-term outcomes of a new technique, robotic rectus abdominis medialization (rRAM), for DR repair with a concomitant ventral hernia. METHODS: Patients who underwent rRAM for repair of DR and a concomitant ventral hernia were identified between January 2015 and December 2020. The results are from a single surgeon at a single institution. RESULTS: A total of 40 patients were identified, 29 of which were female. The mean age was 43 years, the mean body mass index was 27 kg/m 2 , and the mean inter-rectus distance was 6 cm based on available preoperative imaging. The median postoperative length of stay was 1 day, and the median follow-up time was 1 month. Within 30 postoperative days, 3 patients were re-admitted and 5 developed complications, of which 1 required operative re-intervention for seroma. Beyond 30 days, 3 patients required operative re-intervention most commonly for persistent pain from suture material. On the basis of computed tomography scans performed at a mean of 30 months after the date of service, the mean postoperative inter-rectus distance was 1 cm; 1 patient had DR recurrence, and 1 patient developed a new incisional hernia without DR recurrence. There was no hernia recurrence. CONCLUSIONS: rRAM is a safe and effective technique for DR repair with a concomitant ventral hernia. Further studies are needed to determine how outcomes from this robotic approach compare with those from different robotic, laparoscopic, and open techniques.

Comparison of outcomes of the extended-view totally extraperitoneal rives-stoppa (eTEP-RS) and the intraperitoneal onlay mesh with defect closure (IPOM-plus) for W1-W2 midline incisional hernia repair-a single-center experience.

BACKGROUND: The eTEP technique is a new approach that has recently gained popularity in abdominal wall hernia surgery. This study aimed to compare the outcomes of the eTEP-RS and IPOM-plus procedures in W1 and W2 midline incisional abdominal wall hernia (IAWH) repairs performed by the same surgeon. METHODS: Prospectively collected data of laparoscopic abdominal wall repairs performed on 61 patients with eTEP between November 2018 and April 2022 and on 67 patients with IPOM-plus between January 2016 and April 2022 were retrospectively analyzed. A total of 74 out of 128 patients, 30 in the eTEP-RS group and 44 in the IPOM-plus group, who underwent W1-W2 midline incisional hernia repair were included in the study. The mean follow-up was 24 months in the eTEP-RS group and 45 months in the IPOM-plus group. RESULTS: There was no statistically significant difference between the groups regarding age, sex, BMI, ASA score, or active smoking. No difference was seen between the two groups in terms of the mean defect area (MDA, 28.17 cm2 vs. 27.41 cm2, p = 0.84), but the mean mesh area (MMA) and mesh/defect (M/D) ratio were higher in the eTEP-RS group (404.11 cm2 vs. 267.85 cm2, p < 0.001 and 20.96 vs. 12.36, p = 0.004). In the eTEP-RS group, the hospital length of stay (LOS) (1.48 days vs. 2.58 days, p < 0.001) and pain on the first and 10th postoperative days were significantly lower (p < 0.001), while the operative time was significantly longer (204.07 min vs. 88.33 min, p < 0.001). There was no significant difference in terms of intraoperative complications (p = 0.56), seroma formation (p = 0.83), or recurrence (p = 0.83). CONCLUSION: The eTEP-RS technique has advantages over the IPOM-plus approach, such as a shorter LOS and less early postoperative pain with W1-W2 midline IAWH repair. However, the eTEP technique has a longer operative time.

Prophylactic Mesh Placement During Formation of an End-colostomy: Long-term Randomized Controlled Trial on Effectiveness and Safety.

OBJECTIVE: The aim of this study was to determine if prophylactic mesh placement is an effective, safe, and cost-effective procedure to prevent parastomal hernia (PSH) formation in the long term. BACKGROUND: A PSH is the most frequent complication after stoma formation. Prophylactic placement of a mesh has been suggested to prevent PSH, but long-term evidence to support this approach is scarce. METHODS: In this multicentre superiority trial patients undergoing the formation of a permanent colostomy were randomly assigned to either retromuscular polypropylene mesh reinforcement or conventional colostomy formation. Primary endpoint was the incidence of a PSH after 5 years. Secondary endpoints were morbidity, mortality, quality of life, and cost-effectiveness. RESULTS: A total of 150 patients were randomly assigned to the mesh group (n = 72) or nonmesh group (n = 78). For the long-term follow-up, 113 patients were analyzed, and 37 patients were lost to follow-up. After a median follow-up of 60 months (interquartile range: 48.6-64.4), 49 patients developed a PSH, 20 (27.8%) in the mesh group and 29 (37.2%) in the nonmesh group ( P = 0.22; RD: -9.4%; 95% CI: -24, 5.5). The cost related to the meshing strategy was € 2.239 lower than the nonmesh strategy (95% CI: 491.18, 3985.49), and quality-adjusted life years did not differ significantly between groups ( P = 0.959; 95% CI: -0.066, 0.070). CONCLUSIONS: Prophylactic mesh placement during the formation of an end-colostomy is a safe procedure but does not reduce the incidence of PSH after 5 years of follow-up. It does, however, delay the onset of PSH without a significant difference in morbidity, mortality, or quality of life, and seems to be cost-effective.

Risk factors of venous thromboembolism after incisional ventral hernia repair.

BACKGROUND: The problem of venous thromboembolic events (VTE) after incisional hernia repair remains relevant. According to the literature the frequency of VTE ranges from 0.2 to 4.2%. The data on risk factors of VTE in this cohort of patients are scarce. Aim of our study is to find frequency and risk factors for VTE development in patients who underwent surgery for incisional ventral hernia. MATERIALS AND METHODS: There were 240 patients enrolled in our retrospective study. We included patients, who were operated for incisional hernia in Saveljev University Surgery Clinic from January 2018 to December 2019. Compression duplex ultrasound of lower extremity veins was performed within median 3 days (min 1 day, max 7 days) after surgery for all participants. The primary endpoint was the occurrence of the VTE event, including deep venous thrombosis (DVT) and pulmonary embolism (PE). RESULTS: VTE was detected in 19 patients, which accounted for 7.9% in analyzed cohort. All patients received standard pharmacological prophylaxis. There were 3 (1.3%) proximal, 16 (6.7%) distal DVT, in one patient (0.4%) distal thrombosis was complicated by symptomatic pulmonary embolism. In multivariate Cox proportional hazard model was found that component separation (HR 3.99, 95% CI 1.14-14.0, p = 0.03), duration of operation in hours (HR 1.67. 95% CI 1.13-2.5, p = 0.011) and body mass index (HR 1.13, 95% CI 1.02-1.2, p = 0.02) were statistically significant risk factors. CONCLUSION: The incidence of postoperative VTE in patients after incisional hernia repair is high with a predominant distal DVT as a thrombotic event. Component separation, duration of operation and body mass index are statistically significant factors of VTE in patients undergoing surgery for incisional hernia.

No Reduction in Parastomal Hernia Rate 3 Years After Stoma Construction With Prophylactic Mesh: Three-year Follow-up Results From STOMAMESH-A Multicenter Double-blind Randomized Controlled Trial.

OBJECTIVE: The primary objective was to compare rates of parastomal hernia (PSH) 3 years after stoma construction with prophylactic mesh or no mesh. A secondary objective was to compare complications requiring reintervention within 3 years. BACKGROUND: Recent studies have shown that a prophylactic mesh does not reduce the rate of PSH contrary to older studies. Long-term data on efficacy and safety is however scarce. METHODS: A randomized controlled double-blind multicenter trial. Patients planned for permanent end colostomy were randomized to either prophylactic mesh in the retromuscular position around the stoma site or no mesh. They were evaluated for PSH clinically and with computed tomography (CT) 3 years after stoma construction. Medical records of all patients included were also reviewed at 3 years to detect any abdominal or abdominal wall surgery during that period. RESULTS: A total of 232 patients were randomized. At 3 years, 154 patients were available for clinical evaluation and 137 underwent a CT scan. No significant difference in PSH rates was seen between the treatment allocation arms (clinical: P =0.829 and CT: P =0.761, respectively), nor was there a significant difference in the number of reinterventions, but 2 patients had their mesh removed at emergency surgery. CONCLUSIONS: Prophylactic mesh does not reduce the rate of PSH and cannot be recommended for routine use.

[Surgical treatment of enterocutaneous fistulas in patients with ventral incisional hernia]. / Khirurgicheskoe lechenie naruzhnykh kishechnykh svishchei v posleoperatsionnykh gryzhakh.

OBJECTIVE: To determine the optimal surgical treatment in patients with enterocutaneous fistulas combined with ventral incisional hernia. MATERIAL AND METHODS: There were 24 patients with enterocutaneous fistulas combined with ventral incisional hernia. Enterocutaneous fistula was noted in 19 cases, enteroatmospheric fistula - in 5 patients. RESULTS: Simultaneous fistula closure and abdominal wall repair were performed in 14 patients (mesh repair in 5 cases and local approximation of tissues in 9 cases). Postoperative complications occurred in 8 patients, hernia recurrence in long-term period developed in 7 people. Two-stage closure of abdominal wall defect was carried out in 10 patients. Fistula closure was followed by edge-to-edge anterior abdominal wall repair in 5 cases, skin edges were approximated by interrupted sutures or open wound management was performed. There were no postoperative complications and hernia recurrence in this group. CONCLUSION: Surgical treatment of patients with enterocutaneous fistulas combined with hernia should be performed in two stages, i.e. enterocutaneous fistula closure with subsequent hernia repair.

Cost of postoperative complications after general surgery at a major Canadian academic centre.

BACKGROUND: In a fiscally constrained health care environment, the need to reduce unnecessary spending is paramount. Postoperative complications contribute to hospital costs and utilization of health care resources. OBJECTIVE: The purpose of this observational study was to identify the cost associated with complications of common general surgery procedures performed at a major academic hospital in Toronto, Ontario. METHODS: The institutional National Surgical Quality Improvement Program database was used to identify complications in patients who underwent general surgical procedures at our institution from April 2015 to February 2018. A mix of elective and emergent cases was included: bariatric surgery, laparoscopic appendectomy, laparoscopic cholecystectomy, thyroidectomy, right hemicolectomy and ventral incisional hernia repair. The total cost for each visit was calculated by adding all the aggregate costs of inpatient care. Median total costs and the breakdown of cost components were compared in cases with and without complications. RESULTS: A total of 2713 patients were included. Nearly 6% of patients experienced at least one complication, with an incidence ranging from 1.1% after bariatric surgery to 23.8% after right hemicolectomy. The most common type of complication varied by procedure. Median total costs were significantly higher in cases with complications, with a net increase ranging from $2989 CAD (35% increase) after bariatric surgery to $10 459 CAD (161% increase) after ventral incisional hernia repair. CONCLUSION: Postoperative complications after both elective and emergent general surgery procedures add substantially to hospital costs. Quality improvement initiatives targeted at decreasing postoperative complications could significantly reduce costs in addition to improving patient outcomes.
