Parastomal hernia repair

Modified Frailty Index Predicts Postoperative Complications Following Parastomal Hernia Repair

BACKGROUND

The 5-factor frailty index (5-mFI), validated frailty index with Spearmen rho correlation of .95 and C statistic >.7 for predicting postoperative complications, can be preoperatively used to stratify patients prior to parastomal hernia repairs.

METHODS

Retrospective review of the American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) database identified patients from 2015 to 2020. 5-mFI scores were calculated by adding one point for each comorbidity present: diabetes mellitus, congestive heart failure (CHF), hypertension requiring medication, severe chronic obstructive pulmonary disease (COPD), non-independent functional status. Primary endpoint was 30-day overall complications; secondary endpoints were 30-day readmission, reoperation, and discharge to care facility.

RESULTS

2924 (52.2% female) patients underwent elective parastomal hernia repair. Univariate analysis showed 5-mFI > 2 had higher rates of overall (P = .008), pulmonary (P = .002), cardiovascular (P = .003)), hematologic (P = .003), and renal (P = .002) complications and higher rates of readmission (P = .009), reoperation (P = .001), discharge to care facility (P < .001), and death (P < .001). Multivariate analysis identified a 5-mFI of 2 or more as an independent risk factor for overall complications [OR: 1.40, 1.03-1.78; P = .032], pulmonary complications [2.97, 1.63-5.39; P < .001], hematological complications [1.60, 1.03-2.47; P = .035], renal complications [2.04, 1.19-3.46; P = .009], readmission [1.54, 1.19-1.99; P < .001], and discharge to facility [2.50, 1.66-3.77; P < .001]. Reoperation was not signification on multivariate analysis.

CONCLUSIONS

Parastomal hernia repair patients with 5-mFI score of >2 had higher risk of renal, cardiovascular, pulmonary, and hematologic complications, readmissions, longer hospitalization, discharge to care facility, and mortality, and can be useful during preoperative risk stratification.

Surgical management of parastomal hernia following radical cystectomy and ileal conduit: A french multi-institutional experience

BACKGROUND

Parastomal incisional hernia (PH) is a frequent complication following the creation of an ileal conduit (IC), and it can be a significant detriment to quality of life. The aim of this study was to evaluate outcomes of PH repair following IC for urinary diversion.

METHOD

A multicenter retrospective study was conducted of 6 academic hospitals in France. The study's population included patients who underwent surgical treatment for parastomal hernia following IC creation from 2013 to 2021.

RESULTS

Fifty-one patients were included in the study. Median follow up was 15.3 months. Eighteen patients presented with a recurrence (35%), with a median time to recurrence of 11.1 months. The vast majority of PH repair was performed through an open approach (88%). With regard to technique, Keyhole was the most reported technique (46%) followed by Sugarbaker (22%) and suture only (20%). The Keyhole technique was associated with a higher risk of recurrence compared to the Sugarbaker technique (52% vs 10%, p = 0.046). Overall, there was a 7.8% rate of major complications without a statistical difference between PH repair techniques for major complications.

CONCLUSION

Surgical treatment of parastomal hernia following IC was associated with a high risk of recurrence. Novel surgical approaches to PH repair should be considered.

Spontaneous Resolution of Parastomal Gallbladder Herniation After Attempted Surgical Intervention: A Case Report and Review of the Literature

Cholecystic parastomal herniation is a rare condition that has only been documented 16 times in the literature. We present a case report and literature review of cholecystic parastomal herniation managed with diagnostic laparoscopy without cholecystectomy or hernia repair. Furthermore, we assess the demographics, presentation, stoma types, and management of cholecystic parastomal hernias across all documented cases.

Surgical strategies for recurrent parastomal hernia after a primary repair with a Dynamesh® IPST mesh

PURPOSE

To introduce our surgical strategies for recurrent parastomal hernia after a primary repair with a Dynamesh^® IPST mesh.

METHODS

Ten patients who underwent recurrent parastomal hernia repair with previous Dynamesh^® IPST mesh use were analyzed retrospectively. Distinct surgery strategies were applied. Accordingly, we investigated the recurrence rate and postoperative complications in these patients, who were followed for an average of 35.9 months after surgery.

RESULTS

There was no recorded death and no readmission during the 30-day postoperative period. And the lap-re-do Sugarbaker group had no recurrence, whereas the open suture group had one recurrence (16.7%). One patient in the Sugarbaker group developed ileus and recovered conservatively during the follow-up period. There were no other complications, including seroma, mesh infection and bulging, or prolonged postoperative pain.

CONCLUSIONS

We offer two predominant surgery strategies for recurrent parastomal hernia with a previous Dynamesh^® IPST mesh usage, the open suture repair, and the Lap-re-do Sugarbaker repair. Even though the results of the Lap-re-do Sugarbaker repair are satisfactory, we recommend the open suture technique as it is safer in a setting of dense adhesions in recurrent parastomal hernias.

Surgical treatment strategy for recurrent parastomal hernia: Experiences from 17 cases

Purpose

This study aimed to investigate the surgical treatment strategy of recurrent parastomal hernia (PH) and show its safety, feasibility, and outcomes at a mid-term follow-up.

Methods

A total of 17 cases of recurrent PH treated at our hospital between January 2016 and October 2021 were included in this retrospective analysis. Patient characteristics were recorded, and the classification of PH, operative time, intraoperative blood loss, hernia repair techniques, follow-up times, complications, as well as recurrence were compared and analyzed.

Results

Altogether, 17 patients with recurrent PH underwent successful hernia repair via surgical treatment at The First Affiliated Hospital of Shandong First Medical University and Shandong University Qilu Hospital. No recurrence or severe complications were noted during follow-ups (mean 32.8 ± 3.77 [range 3–68] months).

Conclusions

For recurrent PH, selecting a suitable repair approach based on intraperitoneal conditions such as infection, abdominal adhesions, or the length of the bowel loop, can help in achieving better therapeutic results. The lap-redo + Sugarbaker technique is worth recommending when the appropriate conditions are met.

Biologic vs Synthetic Mesh for Parastomal Hernia Repair: Post Hoc Analysis of a Multicenter Randomized Controlled Trial

BACKGROUND

Parastomal hernias are often repaired with mesh to reduce recurrences, but the presence of an ostomy increases the wound class from clean to clean-contaminated/contaminated and makes the choice of mesh more controversial than in a strictly clean case. We aimed to compare the outcomes of biologic and synthetic mesh for parastomal hernia repair.

STUDY DESIGN

This is a post hoc analysis of parastomal hernia repairs in a randomized trial comparing biologic and synthetic mesh in contaminated ventral hernia repairs. Outcomes included rates of surgical site occurrences requiring procedural intervention (SSOPI), reoperations, stoma/mesh-related adverse events, parastomal hernia recurrence rates (clinical, patient-reported, and radiographic) at 2 years, quality of life (EQ-5D, EQ-5D Visual Analog Scale, and Hernia-Related Quality of Life Survey), and hospital costs up to 30 days.

RESULTS

A total of 108 patients underwent parastomal hernia repair (57 biologic (53%) and 51 synthetic (47%)). Demographic and hernia characteristics were similar between the two groups. No significant differences in SSOPI rates or reoperations were observed between mesh types. Four mesh erosions into an ostomy requiring reoperations (2 biologic vs 2 synthetic) occurred. At 2 years, parastomal hernia recurrence rates were similar for biologic and synthetic mesh (17 (29.8%) vs 13 (25.5%), respectively; P=.77). Overall and hernia-related quality of life improved from baseline and were similar between the two groups at 2 years. Median total hospital cost and median mesh cost were higher for biologic compared to synthetic mesh.

CONCLUSION

Biologic and synthetic mesh have similar wound morbidity, reoperations, 2-year hernia recurrence rates, and quality of life in parastomal hernia repairs. Cost should be considered in mesh choice for parastomal hernia repairs.

Comparing Sugarbaker versus keyhole mesh technique for open retromuscular parastomal hernia repair: study protocol for a registry-based randomized controlled trial

Background

Parastomal hernia, common after stoma creation, negatively impacts patient quality of life. For patients with a permanent stoma, durable parastomal hernia repair remains a challenge, with few high-quality studies for guidance. An alternative to open retromuscular parastomal hernia repair with retromuscular “keyhole” mesh is the recent Sugarbaker modification. We aim to compare these two techniques in a head-to-head prospective study.

Methods

This is a registry-based randomized controlled trial designed to investigate whether the retromuscular Sugarbaker technique is superior to the retromuscular keyhole technique for parastomal hernia repair. The primary study endpoint is parastomal hernia recurrence at 2 years. Secondary endpoints include hospital length-of-stay, readmission, wound morbidity, mesh-related complications, re-operation, all 30-day morbidity, and patient-reported outcomes, including hernia-related quality of life, stoma-specific quality of life, pain, and decision regret.

Discussion

Based on the post hoc analysis of a recent randomized controlled trial, we hypothesize that the retromuscular Sugarbaker technique will reduce parastomal hernia recurrence by 20% at 2 years compared to the retromuscular keyhole mesh technique. The results of this study may provide evidence-based guidance for surgeons repairing parastomal hernias.

Parastomal gallbladder herniation: A case report and review of the literature

•

Gallbladder herniation is a rare complication of a parastomal hernia, affecting primarily elderly females.

•

For patients with parastomal swelling and pain gallbladder herniation should be included in the differential diagnosis.

•

Elderly patients with multiple comorbidities may benefit from a conservative approach instead of surgery.

•

The use of prophylactic mesh when creating a permanent end colostomy reduces the rate of parastomal hernias.

Introduction

Parastomal hernia is a common complication of patients living with an enterostomy. However, a parastomal hernia involving the gallbladder is a rare condition with only eight cases documented in the literature.

Presentation of case

We report the case of a 69-year old female who underwent an open right hemicolectomy with creation of a colostomy and terminal ileostomy. She presented with parastomal swelling and pain 16 months later. A computed tomography scan revealed a parastomal herniation of the gallbladder. We elected to proceed with a cholecystectomy and hernia repair, the patient was asymptomatic at her last follow-up.

Discussion

A systematic search of the literature found eight previously published cases. This condition primarily affects elderly females. Five patients were treated surgically and three conservatively, all with a favorable outcome. In frail patients without complicating factors, a conservative treatment approach with surveillance may be safe. We chose a surgical approach due to the symptomatic nature of the presentation and the gallstone containing hernia. This is the first case of a parastomal gallbladder herniation containing a large gallstone.

Conclusion

This report should help broadening the physician’s differential diagnosis in dealing with patients with symptomatic parastomal hernias and provide an example for diagnosis and management of this complication.

From keyhole to sandwich: change in laparoscopic repair of parastomal hernias at a single centre

BACKGROUND

Nearly 50% of patients with an ostomy will develop a parastomal hernia (PSH). Its repair remains a surgical challenge. Both laparoscopic "modified Sugarbaker" (SB) and Keyhole (KH) repair are currently in use, frequently with unsatisfactory results.''Sandwich Repair'' (SR) may be an alternative to reduce recurrence rates. We present the change of our technique from KH to SR.

METHODS

We collected data from all consecutive laparoscopic PSH repairs at our institution from 2004 until now (from 2004 to 2013 treated with KH, from 2014 with SR) and compared the results of the two groups. Primary endpoint was recurrence rate at 1 year. Secondary outcomes were operative time, PO length of hospital stay (LOS), and short and long-term complications.

RESULTS

13 patients underwent SR. Main changes in surgical technique concerned primary defect closure, no stay sutures, use of glue for first mesh fixation, and partial lateral covering of the underlying mesh with a peritoneal flap. Early postoperative course after SR was uneventful and no recurrence at 1 year was recorded. In the KH group (19 patients), short-term complications occurred in two cases (10%), with one parietal hematoma and one case of intensive pain; we had four recurrences at 1 year (21%). LOS was shorter in the SR group (mean 4 days vs 6, p = 0.004). The KH group had 2 (10%) occurrences of chronic seroma and one bowel perforation (5%), while the SR group had one (8%) occurrence of chronic pain. Median follow-up was 26 months (range 13-78) for the SR group and 47 months (12-105) for the KH group.

CONCLUSION

SR is safe and effective in expert hands and provides promising preliminary results.

What's New in the Management of Incarcerated Hernia

Management of incarcerated hernias is a common issue facing general surgeons across the USA. When hernias are not able to be reduced, surgeons must make decisions in a short time frame with limited options for patient optimization. In this article, we review assessment and management options for incarcerated ventral and inguinal hernias.

Decreased collagen type III synthesis in skin fibroblasts is associated with parastomal hernia following colostomy

Parastomal hernia (PH) is a common complication following stoma formation. Abnormal collagen synthesis has been suggested to be involved in PH. The aim of the present study is to explore the effect and mechanism of the collagen synthesis on PH. Data from 157 patients with rectal cancer who received permanent colostomy were retrospectively collected and analyzed to identify the risk factors for PH. Primary culture of skin fibroblasts from patients with or without PH were performed. Cell viability, migration and invasion levels were detected by Cell Counting Kit‑8, and wound healing and Transwell assays, respectively. Reverse transcription quantitative polymerase chain reaction and western blot analysis assays were performed to measure the gene and protein expression levels, respectively. The risk factors of sex, body mass index, aperture size and collagen expression were closely associated with the occurrence of PH. α1 (III) procollagen expression levels were significantly increased in patients with PH, while no marked difference in α1 (I) procollagen mRNA expression levels were observed in patients with or without PH. The viability and motility of fibroblasts from the patients with hernia were suppressed. The expression levels of matrix metalloproteinase (MMP)‑2 and MMP‑9 were decreased while the levels of collagen III and metalloproteinase inhibitor 1 (TIMP‑1) were increased in the fibroblasts from the patients with PH. Silencing TIMP‑1 expression promoted fibroblast migration and invasion and reversed the patterns of MMP‑2, MMP‑9 and collagen III expression in fibroblasts from the patients with PH. Decreased collagen III may inhibit the development of PH, potentially through decreases in TIMP‑1 expression. Therefore, the results from the present study may provide a novel target for PH therapy.

Negative Pressure Wound Therapy with Instillation as Conservative Management for a Large Abdominal Wound Following Incarcerated Parastomal Hernia Repair

Parastomal herniation is a common complication following stoma creation, necessitating surgical repair in up to one-quarter of cases, including emergency cases of incarceration or strangulation. Following hernia repair with or without mesh placement, surgical sites are at risk of infection post-operatively and this is typically resolved by removing the mesh, which can be technically challenging. Few studies have assessed conservative management options for these types of cases. Here, we present a case where negative pressure wound therapy (NPWT) with instillation was utilized for secondary intention healing of a large abdominal wound (20 cm x 23 cm x 5 cm) following mesh infection post-parastomal hernia repair. The patient’s wound was completely healed after eight weeks and she had no long-term complications at the one-year follow-up. NPWT with instillation is an option for the conservative management of large abdominal wounds, which can be considered on a case-by-case basis.

Patients Undergoing Parastomal Hernia Repair Using the Americas Hernia Society Quality Collaborative: A Prospective Cohort Study

BACKGROUND

Parastomal hernia is the most common complication after stoma creation. It can create significant morbidity and is associated with a lower quality of life. Current parastomal hernia repair techniques and outcomes are not well characterized. We aimed to describe patient characteristics, operative techniques, and outcomes of patients undergoing parastomal hernia repair.

STUDY DESIGN

Patients in the Americas Hernia Society Quality Collaborative (AHSQC) ≥18 years old, who underwent parastomal hernia repair were identified. Descriptive statistics were performed for patient demographics, preoperative characteristics, operative details, 30-day follow-up, and patient-reported outcomes. The surgical techniques used in parastomal hernia repair and postoperative outcomes were described, and predictors of open vs minimally invasive surgery (MIS) and type of mesh used were analyzed.

RESULTS

We identified 672 patients in the AHSQC who underwent parastomal hernia repair between 2013 and Nov 2017. Almost all operations were elective, 22% of patents had their stoma reversed, and 94% of repairs used mesh. Elective status and surgeon practice type were associated with use of synthetic mesh. A surgeon's preference for MIS, defect size, and age were associated with use of an MIS approach. Quality of life scores improved for patients who completed a postoperative questionnaire.

CONCLUSIONS

This is the first multi-institutional report of parastomal hernia repair using prospective data complete with operative details. Parastomal hernia repair remains a difficult operation without a clear best practice. Multiple factors appear to influence operative approach. Surgical treatment may improve quality of life at 6 to 12 months postoperatively.

Prosthetic mesh placement for the prevention of parastomal herniation

BACKGROUND

Parastomal herniation is a common problem following formation of a stoma after both elective and emergency abdominal surgery. Symptomatic hernias give rise to a significant amount of patient morbidity, and in some cases mortality, and therefore may necessitate surgical treatment to repair the hernial defect and/or re-site the stoma. In an effort to reduce this complication, recent research has focused on the application of a synthetic or biological mesh, inserted during stoma formation to help strengthen the abdominal wall.

OBJECTIVES

The primary objective was to evaluate whether mesh reinforcement during stoma formation reduces the incidence of parastomal herniation. Secondary objectives included the safety or potential harms or both of mesh placement in terms of stoma-related infections, mesh-related infections, patient-reported symptoms/postoperative quality of life, and re-hospitalisation/ambulatory visits.

SEARCH METHODS

We searched the Cochrane Central Register of Controlled Trials (CENTRAL; the Cochrane Library 2018, Issue 1), Ovid MEDLINE (1970 to 11 January 2018), Ovid Embase (1974 to 11 January 2018), and Science Citation Index Expanded (1970 to 11 January 2018). To identify ongoing studies, we also searched the metaRegister of Controlled Trials (mRCT) on 11 January 2018.

SELECTION CRITERIA

We considered for inclusion all randomised controlled trials (RCTs) of prosthetic mesh (including biological/composite mesh) placement versus a control group (no mesh) for the prevention of parastomal hernia.

DATA COLLECTION AND ANALYSIS

Two review authors independently assessed the studies identified by the literature search for potential eligibility. We obtained the full articles for all studies that potentially met the inclusion criteria and included all those that met the criteria. Any differences in opinion between review authors were resolved by consensus. We pooled study data into a meta-analysis. We assessed heterogeneity by calculation of I² and expressed results for each variable as a risk ratio (RR) with corresponding 95% confidence intervals (CI). We expressed continous outcomes as mean difference (MD) with corresponding 95% CIs.

MAIN RESULTS

We included 10 RCTs involving a total of 844 participants. The primary outcome was overall incidence of parastomal herniation. Secondary outcomes were rate of reoperation at 12 months, operative time, postoperative length of hospital stay, stoma-related infections, mesh-related infections, quality of life, and rehospitalisation rate. We judged the risk of bias across all domains to be low in six trials. We judged four trials to have an overall high risk of bias.The overall incidence of parastomal hernia was less in participants receiving a prophylactic mesh compared to those who had a standard ostomy formation (RR 0.53, 95% CI 0.43 to 0.66; 10 studies, 771 participants; I² = 69%; low-quality evidence). In absolute numbers, the incidence of parastomal hernia was 22 per 100 participants (18 to 27) receiving prophylactic mesh compared to 41 per 100 participants having a standard ostomy formation.There were no differences in the need for reoperation (RR 0.90, 95% CI 0.50 to 1.64; 9 studies, 757 participants; I² = 0%; low-quality evidence); operative time (MD -6.50 (min), 95% CI -18.24 to 5.24; 6 studies, 671 participants; low-quality evidence); postoperative length of hospital stay (MD -0.95 (days), 95% CI -2.03 to 0.70; 4 studies, 500 participants; moderate-quality evidence); or stoma-related infections (RR 0.89, 95% CI 0.32 to 2.50; 6 studies, 472 participants; I² = 0%; low-quality evidence) between the two groups.We were unable to analyse mesh-related infections, quality of life, and rehospitalisation rate due to sparse data or because the outcome was not reported in the included studies.

AUTHORS' CONCLUSIONS

This Cochrane Review included 10 RCTs with a total of 844 participants. The review demonstrated a reduction in the incidence of parastomal hernia in people who had a prophylactic synthetic mesh placed at the time of the index operation compared to a standard ostomy formation. However, our confidence in this estimate is low due to the presence of a large degree of clinical heterogeneity, as well as high variability in follow-up duration and technique of parastomal herniation detection. We found the rate of stoma-related infection to be similar in both the intervention and control groups.

Incisional hernia prevention and use of mesh. A narrative review

Incisional hernias are a very common problem, with an estimated incidence around 15-20% of all laparotomies. Evisceration is another important problem, with a lower rate (2.5-3%) but severe consequences for patients. Prevention of both complications is an essential objective of correct patient treatment due to the improved quality of life and cost savings. This narrative review intends to provide an update on incisional hernia and evisceration prevention. We analyze the current criteria for proper abdominal wall closure and the possibility to add prosthetic reinforcement in certain cases requiring it. Parastomal, trocar-site hernias and hernias developed after stoma closure are included in this review.

Stoma Complications

When created properly, an ileostomy or colostomy can dramatically improve a patient's quality of life. Conversely, when a patient develops complications related to their stoma, the impact on physical and mental health can be profound. Unfortunately, significant morbidity is associated with stoma creation conveying high rates of both early and late-term complications. Early complications include stomal ischemia/necrosis, retraction, mucocutaneous separation, and parastomal abscess. Late complications include parastomal hernia, prolapse, retraction, and varices. This review will discuss commonly occurring nondermatological stoma complications and detail management strategies for the ostomate and the surgeon.

Intestinal Perforation Following Ileoscopy Through a Prolapsed Stoma in an Pediatric Intestinal Transplant Recipient With an Unrecognized Parastomal Hernia

Ileoscopy with mucosal biopsy is fundamental in the management and surveillance of inflammatory bowel disease patients and intestinal transplant recipients. There is a paucity of data describing the risks of ileoscopy in the presence of a prolapsed stoma. Parastomal hernias are frequently associated with prolapsed stomas. We report the first case of perforation during ileoscopy in the setting of a prolapsed stoma and unrecognized parastomal hernia. Recognition of parastomal hernia associated with stoma prolapse is of paramount importance in patients undergoing ileoscopy as it may increase the risk of perforation.

Prophylactic mesh at end-colostomy construction reduces parastomal hernia rate: a randomized trial

AIM

Parastomal hernia (PSH) is the most common complication of an end-colostomy and about one-quarter of patients need operative repair, which is often unsuccessful. A randomized trial was carried out to compare the results of using mesh or no mesh at the time of formation of a colostomy with the clinical identification of PSH as the primary outcome.

METHOD

In this two-centre randomized trial (Oslo University Hospital and Sykehuset Innlandet Hospital Trust, Norway), patients with rectal cancer undergoing open pelvic surgery were randomized to receive a retromuscular synthetic mesh (study group, n = 32) or no mesh (control group, n = 26) at the time of end-colostomy formation. Postoperative follow up was not blinded and included clinical examination and routine CT.

RESULTS

The median period of follow up was 40 (range: 84) months. There were no differences in demographic variables or complications between the study and control groups. PSH developed in two patients of the study group and in 12 of the control group [OR = 0.04 (95% CI: 0.01-0.30) and hazard ratio 0.134 (95% CI: 0.030-0.603); P < 0.001]. The number needed to treat to avoid one PSH was 2.5 patients. CT demonstrated an increase over time in the size of the fascial orifice in patients with PSH without mesh prophylaxis, in contrast to a stable size in patients with mesh and in the control patients who did not develop PSH.

CONCLUSION

The retromuscular insertion of synthetic mesh at the time of formation of an end-colostomy reduced the risk of PSH.

Current state of laparoscopic parastomal hernia repair: A meta-analysis

AIM: To evaluate the efficacy and safety of the laparoscopic approaches for parastomal hernia repair reported in the literature.

METHODS: A systematic review of PubMed and MEDLINE databases was conducted using various combination of the following keywords: stoma repair, laparoscopic, parastomal, and hernia. Case reports, studies with less than 5 patients, and articles not written in English were excluded. Eligible studies were further scrutinized with the 2011 levels of evidence from the Oxford Centre for Evidence-Based Medicine. Two authors reviewed and analyzed each study. If there was any discrepancy between scores, the study in question was referred to another author. A meta -analysis was performed using both random and fixed-effect models. Publication bias was evaluated using Begg’s funnel plot and Egger’s regression test. The primary outcome analyzed was recurrence of parastomal hernia. Secondary outcomes were mesh infection, surgical site infection, obstruction requiring reoperation, death, and other complications. Studies were grouped by operative technique where indicated. Except for recurrence, most postoperative morbidities were reported for the overall cohort and not by approach so they were analyzed across approach.

RESULTS: Fifteen articles with a total of 469 patients were deemed eligible for review. Most postoperative morbidities were reported for the overall cohort, and not by approach. The overall postoperative morbidity rate was 1.8% (95%CI: 0.8-3.2), and there was no difference between techniques. The most common postoperative complication was surgical site infection, which was seen in 3.8% (95%CI: 2.3-5.7). Infected mesh was observed in 1.7% (95%CI: 0.7-3.1), and obstruction requiring reoperation also occurred in 1.7% (95%CI: 0.7-3.0). Other complications such as ileus, pneumonia, or urinary tract infection were noted in 16.6% (95%CI: 11.9-22.1). Eighty-one recurrences were reported overall for a recurrence rate of 17.4% (95%CI: 9.5-26.9). The recurrence rate was 10.2% (95%CI: 3.9-19.0) for the modified laparoscopic Sugarbaker approach, whereas the recurrence rate was 27.9% (95%CI: 12.3-46.9) for the keyhole approach. There were no intraoperative mortalities reported and six mortalities during the postoperative course.

CONCLUSION: Laparoscopic intraperitoneal mesh repair is safe and effective for treating parastomal hernia. A modified Sugarbaker approach appears to provide the best outcomes.

Parastomal hernia repair

Parastomal herniation is a common clinical occurrence. Historically, there has been a high recurrence rate after repair, and conservative management is usually recommended for patients with mild symptoms. When operative intervention is warranted, we opt for a laparoscopic mesh sublay over the fascial defect and lateralization of the stoma limb, or the Sugarbaker technique. In patients who are considered poor risk for laparoscopy/laparotomy requiring repair, we perform a fascial onlay with mesh utilizing an anterior circumstomal approach.
