Parastomal Hernia: direct repair versus relocation: is stoma relocation worth the risk? A comparative meta-analysis and systematic review

Parastomal hernia is a prevalent and challenging complication in patients with stomas, frequently necessitating surgical intervention. The two primary approaches to parastomal hernia repair- direct repair without relocation and stoma relocation- offer distinct benefits and drawbacks. This systematic review and meta-analysis aimed to compare the efficacy and safety of stoma relocation versus direct repair in managing parastomal hernia. Following PRISMA guidelines, we conducted a systematic review and meta-analysis of studies involving adult patients (≥ 18 years) with parastomal hernia who underwent either stoma relocation or direct repair, with a focus on clinically relevant outcomes. A comprehensive search of Web of Science, PubMed, Scopus, and Cochrane Library databases was conducted up to September 2024. Key short-term outcomes (operative time, surgical site infection, urinary tract infection, bowel obstruction, length of hospital stay, and overall complications) and long-term outcomes (re-admission, recurrence, re-operation, and mortality) were extracted. Statistical analysis included risk ratios (RR) for dichotomous outcomes and mean differences (MD) for continuous outcomes. Six studies were included, encompassing both laparoscopic and open-surgical techniques. Direct repair was associated with a significantly shorter operative time (MD: 115 min, 95% CI: 95.71 to 134, P < 0.00001) and a reduced length of hospital stay (MD: 2 days, 95% CI: 0.40 to 3.9, P = 0.02). While reoperation rates were significantly lower in the relocation group (RR: 0.15, 95% CI: 0.03 to 0.62, P = 0.009), other outcomes-including recurrence, re-admission, and overall complication rates-showed comparable results between the two approaches. Notably, there were no significant differences in surgical site infection, urinary tract infection, bowel obstruction, or mortality rates. Direct repair may be advantageous for reducing operative time and hospital stay, whereas stoma relocation appears beneficial in reducing reoperation rates. Future research should focus on developing standardized techniques and incorporating patient-specific factors to inform optimal surgical decision-making in parastomal hernia repair.

Short-term outcomes of mesh-suture repair in the treatment of ventral hernias: a single-center study

BACKGROUND

Defect closure with mesh suture is a novel technique for hernia repair. Originally described as the construction of lightweight macroporous polypropylene mesh strips as a suture material, it is now available as an FDA-approved product. Mesh suture better distributes tensile forces and reduces fascial tearing compared to traditional suture but requires less implanted material and tissue dissection compared to planar mesh. Limited studies have demonstrated mesh suture's effectiveness in short-term recurrence rates. This study describes the short-term outcomes of our initial experience with mesh-suture-based herniorrhaphy.

METHODS

This study is an IRB-approved, single-center, retrospective review of surgeon case logs from May 2023 to February 2024. All patients who had undergone hernia repair utilizing mesh suture (Duramesh, Mesh Suture Inc, Chicago, IL) as the method of repair at our medical center were enrolled. A descriptive analysis regarding patient and hernia characteristics was performed and short-term outcomes were analyzed.

RESULTS

We identified 63 patients (Mean age 61, Mean BMI 31.0 kg/m2, 60% female) who had undergone mesh-suture repair since its availability at our institution. Hernias included 31.7% primary, 27.0% incisional, 34.9% parastomal, and 6.4% other. Of these, 8 (12.7%) were recurrent hernia repairs. The average defect size was 41.0 cm2, with a range from 0.25 to 459 cm2. Average length of stay was 3.2 days, with a range of 0 to 20. Eleven patients (17.5%) were readmitted in the 90-day postoperative period. With an average follow-up of 45 days, there were ten surgical site occurrences (including four surgical site infections) and three recurrences (4.8%).

CONCLUSIONS

Our initial experience with mesh-suture herniorrhaphy has demonstrated acceptable short-term rates of surgical site occurrences and recurrences. This provides additional support for its use, particularly in patients where a planar mesh-based repair might traditionally be avoided. Further studies of mesh-suture herniorrhaphy long-term recurrence rates and cost-effectiveness are needed.

Outcomes after surgical repair of primary parastomal hernia

PURPOSE

Parastomal hernia is a frequent complication after stoma construction, with increasing incidence over time. Surgical repair is reported with a high recurrence rate and the evidence on the topic is limited. We conducted a retrospective study to evaluate the incidence of recurrence after parastomal hernia repair and assessed the risk factors and predictors for recurrence at the Regional Hernia Center at Horsens Regional Hospital, Denmark.

METHODS

119 patients underwent primary parastomal hernia repair from January 2017 until April 2021. Mean follow-up period was 72 months. Information including demographic data, non-modifiable risk factors and modifiable risk factors were assessed and analyzed using LASSO to select relevant predictors and GLM was employed hereafter.

RESULTS

Multivariate analysis showed that age, diabetes, IBD, constipation, and fecal incontinence were strong pre-operative predictors, with age, IBD, ileostomy, and colorectal cancer also reaching significance in univariate analyses. Post-operatively, EHS classification 1, and Clavien Dindo Grade 3b were identified as strong predictors in univariate analyses.

CONCLUSION

Recurrence after parastomal hernia repair was 17.64% during a follow-up period of minimum 3.5 years.

Robotic sugarbaker parastomal hernia repair: updated series and outcomes

PURPOSE

To present updated outcomes after previously describing a novel technique for the robotic repair of parastomal hernias.

METHODS

Patients who underwent parastomal hernia repair with a robotic Sugarbaker technique at a tertiary hernia center were identified from an institutional database. The approach involves mesh placement in the intraperitoneal or preperitoneal position after closure of the fascial defect. Baseline demographics, intra-operative variables, and post-operative outcomes were evaluated.

RESULTS

Twenty-six patients were identified who underwent robotic Sugarbaker parastomal hernia repair with mesh. Median age was 61.5 (IQR 58.0-67.0) years, 17 (65%) were male, and median BMI was 29.5 (IQR 25.7-32.6) kg/m2. Stoma types included 11 (42%) colostomies, 8 (31%) ileostomies, and 7 (27%) urostomies. All but one case was elective (96%) and 2 (8%) were recurrent. Median operative time was 182.5 (IQR 149-209) min. Biologic mesh was used in 5 (19%) and synthetic mesh in 21 (81%) cases. Concurrent hernia repair was performed in 11 (42%) cases. Two (8%) patients were converted from a robotic to open procedure. Median length of stay was 4 (IQR 3-6) days. A total of 3 (11.5%) patients underwent reoperation related to obstruction at the stoma site. There were no additional 30-day readmissions, seromas requiring intervention, or wound complications. There were 4 (15%) total recurrences during a median follow up of 29.1 (IQR 10.0-55.8) months.

CONCLUSIONS

Robotic Sugarbaker parastomal hernia repair is an effective technique for minimally invasive repair of parastomal hernias. Care should be taken to prevent obstruction of the stoma related to fascial and peritoneal flap reconstruction or mesh placement, which is a significant risk of this technique.

Long-term outcomes after open parastomal hernia repair at a high-volume center

BACKGROUND

Open parastomal hernia repairs (OPHR) are complex with high recurrence rates and no clear optimal technique. This report summarizes long-term OPHR outcomes at a high-volume hernia center.

METHODS

OPHRs were identified from a prospectively maintained institutional database. Recurrence and wound complication rates were compared across operative techniques using standard statistical analysis.

RESULTS

Of 97 OPHR patients, mean age was 61.9 ± 12.6 years, 56.7% were female, 24.7% were diabetic, and average BMI was 31.3 ± 6.5 kg/m2. Mean defect size was 125.3 ± 130.0cm2 and 41.2% were recurrent. Stomas included colostomies (56.7%), ileostomies (30.9%), and urostomies (12.4%). Patients underwent concurrent ventral hernia repair (56.7%), panniculectomy (22.7%), and component separation (30.9%). Patients either had their stoma reversed (13.4%), resited (25.8%), or repaired in situ (60.8%) with suture (11.9%) or mesh (88.1%) in a Sugarbaker (65.4%), keyhole (19.2%), or onlay (15.4%) configuration. Over a mean follow-up of 31.6 ± 35.9 months, wound complications occurred in 18.6% and recurrences in 20.6%. There were no significant differences in recurrence by ostomy type. Recurrence rates were highest after in situ suture repair (42.9%), followed by resiting with mesh (34.8%), in situ with mesh (17.3%), and reversal (0.0%)(p = 0.042). When stomas were resited, prophylactic mesh compared to no mesh did not significantly impact recurrence (28.6%vs.50.0%;p = 0.570). Recurrence rates for in situ repairs were not statistically different by mesh technique (onlay 25.0%, Sugarbaker 17.7%, keyhole 10.0%;p = 0.751), but differed by location(retrorectus 50.0%, intraperitoneal 36.4%, onlay 25.0%, preperitoneal 6.5%;p = 0.035). Multivariable analysis did not demonstrate any independent predictors of recurrence or wound complications.

CONCLUSION

This study represents the largest series to date describing long-term OPHR outcomes with a variety of techniques. Recurrence was greatest after in situ primary repair. There were no recurrences after stoma reversal. After ostomy resiting, all recurrences occurred at the new stoma site, independent of prophylactic mesh use. When the stoma was repaired in situ, preperitoneal mesh placement had the lowest recurrence. Optimal technique for OPHR remains unclear, but these results may inform preoperative discussions and surgical planning.

Robotic parastomal hernia repair in Ileal-conduit patients: short-term results in a single-center cohort study

PURPOSE

To describe and evaluate safety and feasibility of the robotic modified Sugarbaker technique with intraperitoneal underlay mesh (IPUM) for repairing parastomal hernias associated with ileal conduits (ICPSH).

METHODS

This retrospective, single-center cohort study analyzed data from 15 adult patients who underwent robotic ICPSH repair using the modified Sugarbaker IPUM technique between July 2021 and July 2023. The primary endpoints were hernia recurrence rates and 30-day morbidity. Secondary endpoints included length of stay, conversion to open surgery, 30-day readmission, and 30-day reoperation.

RESULTS

The mean patient age was 69.1 years, and 53.3% were female. Most patients (86.6%) had undergone radical cystectomy as the index surgery. The mean operative time was 249 min, with no conversions to open surgery. The 30-day complication rate was 26.7%, and the mean hospital stay was 3.6 days. No hernia recurrences, hydronephrosis, rise in creatinine or distended conduit on imaging suggesting poor drainage were observed during a mean follow-up of 15.2 months.

CONCLUSIONS

The robotic modified Sugarbaker IPUM technique appears safe and feasible for PSH repair in IC patients, with promising short-term outcomes. Further studies with larger cohorts and longer follow-up are needed to confirm its long-term efficacy and establish its role in ICPSH management.

Use of prophylactic mesh to prevent parastomal hernia formation: a systematic review, meta-analysis and network meta-analysis

PURPOSE

To evaluate the effectiveness of prophylactic mesh placement in reducing the incidence of parastomal hernias following colostomy, ileostomy, and ileal conduit formation.

METHODS

A systematic review identified relevant studies evaluating parastomal hernia incidence with prophylactic mesh use during stoma formation. Pairwise meta-analysis and network meta-analysis using Bayesian modeling were performed.

RESULTS

25 studies, consisting of 16 randomized control trials (RCT), 6 follow up studies, and 3 retrospective cohort studies, were included. Prophylactic mesh led to significantly fewer parastomal hernias beyond 6 months follow-up (OR 0.43, 95% CI 0.33-0.58). Hernias were reduced with mesh for both ileal conduits and colostomies. When analyzing hazard ratios (HRs), only 6 studies were included, and a statistically significant difference was observed among both randomized controlled trials (RCTs) (HR 0.75 [0.53, 0.92], p = 0.01) and non-RCTs (HR 0.57 [0.36, 0.92], p = 0.02). Network meta-analysis found the retromuscular approach with mesh had the lowest hernia rate. Regression was non-significant for variations between study types.

CONCLUSION

This meta-analysis demonstrated prophylactic mesh placement during ostomy creation significantly reduced parastomal hernia risk, more prominently beyond 6 months, consistently across randomized trials and observational studies for urologic and gastrointestinal ostomies. The retromuscular technique was most effective.

Robotic parastomal hernia repair: A single-center cohort study

Parastomal hernia is a common occurrence following stoma construction, necessitating surgical intervention in symptomatic cases. This study presents a comprehensive analysis of Robotic-Assisted Parastomal Hernia Repair (r-PSHR), utilizing the Da Vinci Xi™ Surgical System. Retrospective analysis was conducted on patients undergoing r-PSHR at a high-volume center. Surgical variables, complications, and recurrence rates were assessed. The primary technique involved a modified Sugarbaker intraperitoneal onlay mesh. Eighty-six patients underwent r-PSHR, predominantly females (59.3%), with mean age 60.8 years. Mean BMI was 31.0. Most patients were classified as ASA 2 (31.4%) or ASA 3 (65.1), with 64.6% having no prior PSH repair. Index procedures primarily involved laparoscopic colonic resections (27.8%) and open abdominoperineal resections (27.8%). Parastomal hernias were mainly associated with end ileostomy (50%) and end colostomy (47.7%). A hybrid modification was required in 22.1% of cases, with only one conversion to open repair. Mean operative time was 257 min. Thirty-day morbidity was 40.7% and includes ileus (24.4%), deep surgical-site infections (7.0%), acute kidney injury (5.8%), and sepsis (5.8%). Grade IIIB complications occurred in 5.8% of cases. Thirty-day readmissions were observed in 19.8% of cases. There were five cases (5.8%) of recurrence within 15 months post-surgery. This study highlights the effectiveness of r-PSHR in managing parastomal hernia. R-PSHR shows promising outcomes with an acceptable post-operative occurrence profile and a favorable recurrence rate.

Stoma Complications

Stoma-related complications are among the most common sources of perioperative morbidity in colorectal surgery. Complications can occur intraoperatively, in the immediate postoperative period, or even months to years after stoma creation. Although some will require urgent surgical intervention, most are treated nonoperatively with a combination of education, appliance adjustment, and behavioral intervention. Optimal management of stoma complications nearly always requires a multidisciplinary team approach, including surgeons, enterostomal therapists, and other allied health professionals, depending on the specific situation. Patients with a functional stoma should be expected to be able to do anything that patients without a stoma can do with minimal exceptions. The treatment of stoma complications therefore centers on improving stoma function and maximizing quality of life. Although timely and comprehensive intervention will result in the resolution of most stoma complications, there is no substitute for preoperative planning and meticulous stoma creation.

Body morphometry may predict parastomal hernia following radical cystectomy with ileal conduit

OBJECTIVE

To investigate whether preoperative body morphometry analysis can identify patients at risk of parastomal hernia (PH), which is a common complication after radical cystectomy (RC).

PATIENTS AND METHODS

All patients who underwent RC between 2010 and 2020 with available cross-sectional imaging preoperatively and at 1 and 2 years postoperatively were included. Skeletal muscle mass and total fat mass (FM) were determined from preoperative axial computed tomography images obtained at the level of the L3 vertebral body using Aquarius Intuition software. Sarcopenia and obesity were assigned based on consensus definitions of skeletal muscle index (SMI) and FM index (FMI). PH were graded using both the Moreno-Matias and European Hernia Society criteria. Binary logistic regression and recursive partitioning were used to identify patients at risk of PH. The Kaplan-Meier method with log-rank and Cox proportional hazards models included clinical and image-based parameters to identify predictors of PH-free survival.

RESULTS

A total of 367 patients were included in the final analysis, with 159 (43%) developing a PH. When utilising binary logistic regression, high FMI (odds ratio [OR] 1.63, P < 0.001) and low SMI (OR 0.96, P = 0.039) were primary drivers of risk of PH. A simplified model that only relied upon FMI, SMI, and preoperative albumin improved the classification of patients at risk of PH. On Kaplan-Meier analysis, patients who were obese or obese and sarcopenic had significantly worse PH-free survival (P < 0.001).

CONCLUSION

Body morphometry analysis identified FMI and SMI to be the most consistent predictors of PH after RC.

Risk factors for parastomal hernia after abdominoperineal resection of rectal cancer

Purpose

To investigate risk factors associated with the formation of parastomal hernia after Miles operation, and to provide scientific evidence for the prevention and treatment of parastomal hernia.

Methods

Clinical data from 205 patients with rectal cancer undergoing Miles operation in the Department of General Surgery, Affiliated Hospital of Xuzhou Medical University between May 2016 and May 2021 were analyzed retrospectively. Fourteen potential factors were selected and analyzed by single factor analysis and two element logistic regression analysis for their potential relationship to incidence of parastomal hernia.

Results

49 cases of parastomal hernia occurred among 194 patients during follow-up (incidence 25.26%). Univariate analysis showed that age, thickness of subcutaneous abdominal fat, BMI, and stoma pathway were related to the formation of post-surgical parastomal hernia (P < 0.05). Two element logistic regression analysis showed that advanced age, thickness of subcutaneous abdominal fat, BMI > 25 kg/m2, and transperitoneal surgical approach were independent risk factors for the formation of parastomal hernia after Miles operation (P < 0.05).

Conclusion

Advanced age, thickness of subcutaneous abdominal fat, BMI > 25 kg/m2, and transperitoneal surgical approach are independent risk factors for the formation of parastomal hernia after Miles.

Evaluating EHS parastomal hernia classification for surgical planning: a retrospective analysis of 160 consecutive cases in a single center

INTRODUCTION

Parastomal hernia (PH) is a prevalent complication following ostomy formation, presenting significant challenges in surgical management. This study aims to validate the European Hernia Society classification for PH through the application of the Hybrid Parastomal Endoscopic Repair (HyPER) method. The study focuses on establishing the practical utility of the European Hernia Society classification in a clinical setting, particularly in guiding surgical approaches and improving patient outcomes.

MATERIALS AND METHODS

This retrospective observational study aimed to assess the utility of the European Hernia Society classification in planning surgical strategies for parastomal hernias. The validation of the classification of PH was based on the experience involving 160 patients in single center. Patients were classified according to the European Hernia Society criteria, and data were collected on patient demographics, clinical presentations, and surgical outcomes. Main goal was to assess the consistency and applicability of the European Hernia Society classification in predicting surgical challenges and outcomes.

RESULTS

The study found a predominance of complex Type III and IV hernias. The European Hernia Society classification was effective in categorizing PH, aiding in surgical planning and highlighting the increased complication rates associated with more complex hernia types. This study represents the largest single-center cohort treated for PH by a single team, providing a controlled evaluation of the HyPER technique's effectiveness.

CONCLUSIONS

The validation of the European Hernia Society classification in this study is a significant advancement in the standardization of PH management. The findings demonstrate the classification's utility in enhancing surgical planning and patient-centered care. The study also opens avenues for further research into standardized approaches and techniques in PH treatment.

Lap-re-Do Keyhole versus Lap-re-Do Sugarbaker techniques in large parastomal hernia repair: a retrospective cohort study

PURPOSE

To review the safety and efficacy of Lap-re-Do technique in the treatment of large parastomal hernia.

METHODS

We retrospectively analyzed the recurrence and complications of 81 patients with large parastomal hernia who underwent Lap-re-Do technique in Huashan Hospital of Fudan University from May 2010 to December 2019. And the patients should be able to complete follow-up. With such criteria, we included 40 Lap-re-Do Keyhole patients and 41 Lap-re-Do Sugarbaker patients. Observation time was defined as time to recurrence, death, or last nonevent visit.

RESULTS

In large parastomal hernias, Lap-re-Do had a recurrence rate of 25.9% and complication rate of 16.0%, and reoperation rate of 9.9% during the average follow-up time of 41.1 ± 17.8 months. Recurrence rates were 40% (16/40) after Lap-re-Do Keyhole repair and 12.2% (5/41) after Lap-re-Do Sugarbaker repair. Complication rates were 12.5% after Lap-re-Do keyhole and 19.5% after Lap-re-Do Sugarbaker repair Re-operation rates referred to Lap-re-Do keyhole repair were 15% and Lap-re-Do Sugarbaker repair 4.9% during follow-up.The majority of reoperations were indicated by recurrence.

CONCLUSIONS

Large parastomal hernias are still difficult to be treated. Lap-re-Do Sugarbaker is recommended as an appropriate procedure to close the hernia ring, removing the lengthy colostomy, and effectively reduce recurrence and complication rates.

Parastomal Gallbladder Herniations: A Systematic Review

Parastomal hernias (PSHs) are a common complication following stoma placement. The presence of the gallbladder within a PSH is a rare and unusual occurrence, posing a significant management challenge for surgeons once encountered. We conducted a systematic review of the literature to evaluate the management and outcomes of parastomal gallbladder herniations. A comprehensive search was performed across the PubMed, Embase, and Medline databases using the search terms "gallbladder" AND "parastomal hernia." Additionally, a reference check of the results was conducted to identify further case reports. Eighteen case reports were included in the review. The mean age of the reported cases was 77.2 years, with a female predominance of 88.9% (n = 16). Seventy-seven percent (n = 14) of patients had an original ileal stoma or conduit. The average duration from stoma placement to clinical presentation was 5.8 years and abdominal pain was the most common presenting complaint. CT imaging was the most frequently utilised modality for successful diagnosis, with only two herniations identified during surgical exploration. Notably, 66.6% (n = 12) of patients experienced associated gallbladder complications, including cholecystitis, torsion, incarceration, and even perforation, all of which necessitated cholecystectomy. Cholecystic parastomal herniation is a rare phenomenon that should be considered in differential diagnoses for similar presentations. Currently, no standardized classification or management approach exists. Based on our findings, we propose classifying gallbladder herniations into two categories: simple (without inflammatory sequelae) and complicated (with cholecystitis, gallbladder torsion, incarceration, or perforation). Simple herniations may be managed electively with intraoperative reduction of the gallbladder. In contrast, complicated herniations presenting during acute admissions require emergency surgical intervention, involving a combined cholecystectomy and PSH repair.

Repair of Parastomal Hernias

Parastomal hernias are an inevitable consequence of ostomy formation and their repairs remain a challenge to many surgeons. With multiple systems of classification and a multitude of techniques for hernia repair ranging from suture to mesh repair, the literature remains sparse with regards to the optimal method of repair. The authors describe the most commonly adopted techniques, discuss preventative measures, and review the current literature in the context of perioperative outcomes and hernia recurrence.

Comparison of the 3-D mesh and Sugarbaker repair for parastomal hernia: a single center experience in China

Parastomal hernias (PSH) are difficult to manage and associated with high rates of postoperative recurrence and complications. Sugarbaker and three-dimensional (3-D) mesh repair are commonly used methods for the surgical treatment of PSH. However, the efficacy and safety of these surgical techniques have not been adequately compared. Patients with PSH who received 3-D mesh or Sugarbaker repair at our center from August 2012 to May 2023 were included. We retrospectively analyzed their demographic data and postoperative outcomes. The primary outcome measure was the recurrence rate at 1-year follow-up. A total of 86 patients were enrolled, involving 53 in the 3-D mesh (62%) group and 33 in the Sugarbaker (38%) group. Most cases (73%) involved were the laparoscopic approach. The recurrence rate at 1-year follow-up was 15% (eight cases) in the 3-D mesh group and 24% (eight cases) in the Sugarbaker group, with no statistical significance (P = 0.29). Additionally, no differences were observed between the 3-D mesh and Sugarbaker groups in the length of hospitalization or in short- and long-term complications. Sugarbaker and 3-D mesh repair have similar clinical efficacy in the surgical treatment of PSH. Further randomized controlled trials are required to confirm these results.Trial registration number.This study was retrospectively registered at clinicaltrials.gov (NCT06077318).

Effect of Sublay Preventive Mesh for Terminal Colostomy on Symptoms and Quality of Life in Patients With Parastomal Hernia: A Post Hoc Analysis of the GRECCAR 7 Cohort

BACKGROUND

Recent randomized clinical trials and meta-analyses confirm that the use of a prophylactic mesh does not significantly reduce the parastomal hernia rate. Data about the benefits of these meshes concerning the symptoms of parastomal hernia are lacking in the existing literature.

OBJECTIVE

The aim of this study was to perform a post hoc analysis of the patients presenting parastomal hernia from the GRECCAR 7 (Groupe de recherche sur la chirurgie du cancer du rectum) randomized clinical trials cohort on whether the presence or the absence of the mesh influenced the symptoms, the quality of life, and complications of patients with parastomal hernias.

DESIGN

We studied the parastomal hernia-related symptoms among the 2 groups of the GRECCAR 7 randomized clinical trial, with or without prophylactic mesh at the time of the index surgery.

SETTINGS

Data were retrospectively extracted and analyzed from the GRECCAR 7 database.

PATIENTS

Patients diagnosed with a parastomal hernia during the 2 years of the GRECCAR 7 study.

MAIN OUTCOME MEASURES

Several prospectively collected data about the symptoms were studied among this population. We also studied the average interval between parastomal hernia repair surgery and both index surgery and diagnosis of parastomal hernia.

RESULTS

Among the 199 patients included in the GRECCAR study, 36 patients (35.6%) in the nonmesh group and 33 patients (33.7%) in the mesh group were diagnosed with clinical and/or radiological parastomal hernia at 2-year follow-up, without a statistically significant difference ( p = 0.89). None of the studied symptoms showed any statistically significant difference between the groups.

LIMITATIONS

This study relies on a relatively small number of patients, and although data were prospectively collected, we lacked some details about the categorization of parastomal hernias.

CONCLUSIONS

We believe that the use of a prosthetic mesh in a sublay position to prevent parastomal hernia in terminal end colostomy patients should no longer be recommended. See Video Abstract .

EFECTO DE LA MALLA PREVENTIVA RETROMUSCULAR PARA COLOSTOMA TERMINAL CON RESPECTO A LOS SNTOMAS Y LA CALIDAD DE VIDA EN PACIENTES CON HERNIA PARAESTOMAL UN ANLISIS POSTHOC DE LA COHORTE GRECCAR

ANTECEDENTES:Los recientes metaanálisis y ensayos clínicos aleatorizados confirman que el uso de una malla profiláctica no reduce significativamente la tasa de hernia paraestomal. En la literatura existente faltan datos sobre los beneficios de estas mallas en relación con los síntomas de la hernia paraestomal.OBJETIVO:El objetivo de este estudio fue realizar un análisis post-hoc de los pacientes que presentaron hernia paraestomal de la cohorte de 7 ensayos clínicos aleatorizados GRECCAR sobre si la presencia o ausencia de la malla influyó en los síntomas, la calidad de vida y las complicaciones de los pacientes con hernias paraestomales.DISEÑO:Estudiamos los síntomas relacionados con la hernia paraestomal entre los dos grupos del ensayo clínico aleatorizado GRECCAR 7, con o sin malla profiláctica en el momento de la cirugía índice.AJUSTES:Los datos fueron extraídos y analizados de manera retrospectiva de la base de datos GRECCAR 7.PACIENTES:Pacientes diagnosticados con hernia paraestomal durante los dos años del estudio GRECCAR 7.PRINCIPALES MEDIDAS DE RESULTADO:Se estudiaron varios datos recopilados de manera prospectiva sobre los síntomas en esta población. También estudiamos el intervalo promedio entre la cirugía reparadora de la hernia paraestomal así como también la cirugía índice como el diagnóstico de la hernia paraestomal.RESULTADOS:De entre los 199 pacientes incluidos en el estudio GRECCAR, 36 pacientes (35,6%) fueron diagnosticados con hernia paraestomal de manera clínica y/o radiológica en el grupo sin malla a los 2 años de seguimiento y 33 (33,7%) en el grupo con malla, sin diferencia estadísticamente significativa ( p = 0,89). Ninguno de los síntomas estudiados mostró diferencias estadísticamente significativas entre los grupos.LIMITACIONES:Este estudio se basa en un número relativamente pequeño de pacientes y, aunque los datos fueron recopilados de forma prospectiva, nos faltaron algunos detalles sobre la categorización de las hernias paraestomales.CONCLUSIONES:Creemos que ya no se debe recomendar el uso de una malla protésica en posición retromuscular para prevenir la hernia paraestomal en pacientes con colostomía terminal.

Repair of parastomal hernias with the intraperitoneal funnel meshes IPST-R and IPST

The treatment of parastomal hernias (PSH) represents a major challenge in hernia surgery. Various techniques have been reported with different outcomes in terms of complication and recurrence rates. The aim of this study is to share our initial experience with the implantation of the DynaMesh-IPST-R and -IPST, intraperitoneal funnel meshes made of polyvinylidene fluoride (PVDF). This is a retrospective observational cohort study of patients treated for PSH between March 2019 and April 2023 using the chimney technique with the intraperitoneal funnel meshes IPST-R or IPST. The primary outcome was recurrence and the secondary outcomes were intraoperative and postoperative complications, the latter assessed using the Clavien-Dindo classification. A total of 21 consecutive patients were treated with intraperitoneal PVDF funnel meshes, 17 with IPST-R and 4 with IPST. There were no intraoperative complications. Overall, no complications occurred in 61.9% (n = 12) of the patients. Major postoperative complications (defined as Clavien-Dindo ≥ 3b) were noted in four cases (19.0%). During the mean follow-up period of 21.6 (range 4.8-37.5) months, one patient (4.8%) had a recurrence. In conclusion, for the treatment of parastomal hernias, the implantation of IPST-R or IPST mesh has proven to be efficient, easy to handle, and very safe. In particular, the low recurrence rate of 4.8%, which is in line with the current literature, is convincing. However, a larger number of patients would improve the validity of the results.

Effects of different mesh materials on complications after prophylactic placement for stoma formation: a systematic review and network meta-analysis

PURPOSE

We primary aimed to synthesise the available data, assess the effectiveness of different mesh materials in prophylactic mesh placement, and rank these materials according to the incidence of parastomal hernia (PSH) and other stoma complications.

METHOD

This network meta-analysis performed a systematic review and meta-analysis according to the Preferred Reporting Items for Systematic Review and Meta-Analysis statement. Four databases were searched for randomised controlled trials of prophylactic mesh placement. The aggregated results were performed in the STATA routine for Bayesian hierarchical random effects models.

RESULT

Thirteen randomised controlled trials from 1203 articles, met the inclusion criteria, including 681 cases without meshes, 65 cases with mesh material of xenogeneic acellular dermis (porcine/bovine), 27 cases with polypropylene/PG910, 114 cases with polypropylene/polyglecaprone (Monocryl), 117 cases with polypropylene/cellulose (ORC), 233 cases with polypropylene, and 35 cases with polypropylene/PVDF. In network A, compared with no mesh, only polypropylene (RR 0.24, 95% CI 0.04-0.80) were significantly associated with a reduction in the incidence of PSH. In network B, no statistical difference regarding stoma complications was found between mesh and no mesh.

CONCLUSION

Based on the network meta-analysis and ranking results, the polypropylene mesh material exhibited the best performance. However, this conclusion needs to be confirmed with larger sample sizes and high-quality randomised controlled trials.

Parastomal hernia prevention with an intraperitoneal prophylactic 3D-funnel mesh: review of the technique and middle-term results

PURPOSE

Parastomal hernia (PH) stands out as a prevalent complication following end colostomies, significantly affecting patients' quality of life. Various surgical strategies, predominantly involving prophylactic mesh deployment, have been explored with variable outcomes. This study details our experience and mid-term outcomes utilizing a funnel-shaped mesh.

METHODS

A single-center, prospective, non-randomized, observational study examined consecutive patients undergoing colorectal surgery with end colostomy, incorporating a 3D-funnel mesh from January 2019 to December 2021 (PM group). A historical cohort of patients with end colostomy without prophylactic mesh served as the comparison (C group). Postoperative morbidity within 30 days was documented, and clinical examinations and radiological tests were employed for parastomal hernia diagnosis during follow-up.

RESULTS

Seventy-two patients participated, with thirty-four in the PM group and thirty-eight in the C group. The PM group experienced 16 postoperative complications, unrelated to the mesh, while the C group recorded 20 complications (p = 0.672). Median follow-up was 22.06 months for the PM group and 63.18 months for the C group. The PM group exhibited a lower parastomal hernia incidence during follow-up (8.8%) compared to the C group(68.4%) (p < 0.001).

CONCLUSION

Prophylactic use of a 3D-funnel mesh appears effective in reducing parastomal hernia incidence in the short and mid-term, without an associated increase in postoperative morbidity.

Robotic modified Sugarbaker technique for parastomal hernia repair: a standardized approach

Parastomal hernia (PSH) is a prevalent long-term morbidity associated with stoma construction, and the optimal operative management remains uncertain. This study addresses the need for a standardized approach to symptomatic PSH repair, focusing on the robotic-assisted modified Sugarbaker technique with composite permanent mesh. The study, conducted in a high-volume colon and rectal surgery referral practice, outlines a systematic approach to patient selection, surgical procedures, and postoperative care. Preoperative evaluations include detailed medical and surgical histories, impact assessments of PSH, and oncological history reviews. The surgical technique involves the Da Vinci Xi™ robotic platform for adhesiolysis, hernia content reduction, stoma revision if needed, narrowing of the enlarged stoma trephine, lateralization of the stoma limb of bowel, and securing the mesh to the abdominal wall. Outcomes are reported for 102 patients undergoing robotic parastomal hernia repair from January 2021 to July 2023. Conversion to open surgery occurred in only one case (0.9%). Postoperative complications affected 39.2% of patients, with ileus being the most frequent (24.5%). Recurrence was observed in 5.8% of cases during an average follow-up of 10 months. In conclusion, parastomal hernia, a common complication post-stoma creation, demands surgical intervention. The robotic-assisted modified Sugarbaker repair technique, as outlined in this paper, offers promising results in terms of feasibility and outcomes.

End-colostomy parastomal hernia repair: a systematic review on laparoscopic and robotic approaches

INTRODUCTION

Parastomal hernia (PSH) is the most common and challenging complication after stoma creation, with an estimated 50% incidence 2 years after the index surgery. Mesh repair is the treatment of choice. Laparoscopic and/or robotic approaches allow acceptable outcomes.

MATERIALS AND METHODS

A systematic literature review from January 2012 to November 2023 was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement. Embase, PubMed, and Scopus search were performed to select articles dealing with minimally invasive surgical treatment for PSH after end colostomy.

RESULTS

603 studies were found, and 24 were chosen. When compared to open surgery, laparoscopy showed decreased postoperative complications and recurrence. The main laparoscopic approaches are the keyhole (KH), the Sugarbaker (SB), and the sandwich technique. Continuous improvement in surgery, mesh technology, and surgeons' expertise led to an amelioration of surgical outcome and recurrence rate after repair. Recent studies showed comparable outcomes for SB and KH techniques, while novel surgical approaches have been proposed in an attempt to further increase the operative and long-term results. Reports on PSH robotic repairs are scarce and describe small series results, suggesting a role of the initial learning curve as a risk factor for complications.

CONCLUSION

End-colostomy PSH surgical repair still represents a challenge for surgeons. Recent evidence has not shown a significant advantage in postoperative complications and recurrence with a specific repair among SB, KH, and sandwich technique. The paucity of data on robotic surgery does not allow to draw definitive conclusion. Further primary, multicentric, and larger cohort studies are needed.

Management of the Difficult Stoma

Fecal ostomy creation is a commonly performed procedure with many indications. Better outcomes occur when preoperative patient education and stoma site marking are provided. Despite a seemingly simple operation, ostomy creation is often difficult and complications are common. Certain risk factors, particularly obesity, are strongly associated with stoma-related complications. The ability to optimize the ostomy and stoma in the operating room and to troubleshoot frequently encountered post-operative stoma-related issues are critical skills for surgeons and ostomy nurses alike.

Management of adult intestinal stomas: The 2023 French guidelines

AIM

Digestive stoma are frequently performed. The last French guidelines have been published twenty years ago. Our aim was to update French clinical practice guidelines for the perioperative management of digestive stoma and stoma-related complications.

METHODS

A systematic literature review of French and English articles published between January 2000 and May 2022 was performed. Only digestive stoma for fecal evacuation in adults were considered. Stoma in children, urinary stoma, digestive stoma for enteral nutrition, and rare stoma (Koch, perineal) were not included.

RESULTS

Guidelines include the surgical landmarks to create digestive stoma (ideal location, mucocutaneous anastomosis, utility of support rods, use of prophylactic mesh), the perioperative clinical practice guidelines (patient education, preoperative ostomy site marking, postoperative equipment, prescriptions, and follow-up), the management of early stoma-related complications (difficulties for nursing, high output, stoma necrosis, retraction, abscess and peristomal skin complications), and the management of late stoma-related complications (stoma prolapse, parastomal hernia, stoma stenosis, late stoma retraction). A level of evidence was assigned to each statement.

CONCLUSION

These guidelines will be very useful in clinical practice, and allow to delete some outdated dogma.

Outcomes of Emergency Parastomal Hernia Repair in Older Adults: A Retrospective Analysis

INTRODUCTION

Parastomal hernias are common and many are never repaired. Emergency parastomal hernia repair (PHR) is a feared complication following ostomy creation, yet the incidence and long-term outcomes of emergency PHR are unknown.

MATERIALS AND METHODS

We performed a retrospective analysis of 100% Medicare claims data (2007-2015) to evaluate complications, readmissions, reoperations, hospitalizations, and mortality after emergency PHR. We used logistic regression and Cox proportional hazard models to determine the association of surgical approach, including repair with ostomy reversal, resiting, mesh, minimally invasive approach, or a myofascial flap. Analysis took place between June 2022 and February 2023.

RESULTS

A total of 6658 patients underwent emergency PHR (mean [standard deviation] age, 75.9 [9.8] y; 4031 female individuals [60.5%]). Overall, 3433 (51.2%) patients underwent primary PHR, 1626 (24.4%) underwent PHR with ostomy resiting, and 1599 (24.0%) underwent PHR with ostomy reversal. In the 30 d after surgery, 4151 (62.3%) patients had complications and 55 (0.83%) underwent reoperation. Compared to local repair, the 30-d odds of complications were lower for patients who underwent ostomy resiting (odds ratio 0.82 [95% confidence interval 0.72-0.93]). Five y after surgery, the cumulative incidence of reoperation was 12.0% and was lowest for patients who underwent PHR with ostomy reversal (hazard ratio 0.15 [95% confidence interval 0.11-0.21]) when compared to local repair.

CONCLUSIONS

Emergency PHR is associated with significant morbidity. However, technique selection may influence outcomes. Understanding the prognosis of emergency PHR may improve decision-making and patient counseling for patients living with this common disease.

Autologous full-thickness skin in the repair of complex ventral hernias: an innovative step into the future of complex hernia repair?

The repair of complex ventral hernias, such as giant incisional or parastomal hernia, is associated with a high risk for complications and recurrence. Some serious complications are related to implantation of synthetic mesh as reinforcement material. Autologous full-thickness skin graft (FTSG) as reinforcement material in the repair of these complex hernias may offer a safe alternative. This is a review of the history of FTSG use in hernia surgery and the experiences of our research group regarding its application over the last decade. The results of FTSG used in the repair of giant ventral hernias are promising, and this method may already be recommended in selected cases. We have also conducted a translational chain of preclinical studies, based on a murine model, to gain a greater understanding of the behaviour of FTSG implanted in various positions in the abdominal wall. The use of intraperitoneal FTSG as reinforcement material in parastomal hernia repair is currently being evaluated in a randomised, controlled, multicentre study.

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.

Surgical management of ostomy complications: a MISSTO-WSES mapping review

BACKGROUND

The creation of an ileostomy or colostomy is a common surgical event, both in elective and in emergency context. The main aim of stoma creation is to prevent postoperative complications, such as the anastomotic leak. However, stoma-related complications can also occur and their morbidity is not negligible, with a rate from 20 to 70%. Most stomal complications are managed conservatively, but, when this approach is not resolutive, surgical treatment becomes necessary. The aim of this mapping review is to get a comprehensive overview on the incidence, the risk factors, and the management of the main early and late ostomy complications: stoma necrosis, mucocutaneous separation, stoma retraction, stoma prolapse, parastomal hernia, stoma stenosis, and stoma bleeding.

MATERIAL AND METHODS

A complete literature research in principal databases (PUBMED, EMBASE, SCOPUS and COCHRANE) was performed by Multidisciplinary Italian Study group for STOmas (MISSTO) for each topic, with no language restriction and limited to the years 2011-2021. An international expert panel, from MISSTO and World Society of Emergency Surgery (WSES), subsequently reviewed the different issues, endorsed the project, and approved the final manuscript.

CONCLUSION

Stoma-related complications are common and require a step-up management, from conservative stoma care to surgical stoma revision. A study of literature evidence in clinical practice for stoma creation and an improved management of stoma-related complications could significantly increase the quality of life of patients with ostomy. Solid evidence from the literature about the correct management is lacking, and an international consensus is needed to draw up new guidelines on this subject.

Parastomal Hernia Repair

Parastomal hernias (PHs) are common and contribute to significant patient morbidity. Despite 45 years of evolution, mesh-based PH repairs continue to be challenging to perform and remain associated with high rates of postoperative complications and recurrences. In this article, the authors summarize the critical factors to consider when evaluating a patient for PH repair. The authors provide an overview of the current techniques for repair, including both open and minimally invasive approaches. The authors detail the mesh-based repair options and review the evidence for choice of mesh to use for repair.

Keyhole Versus Sugarbaker Mesh Configuration in Parastomal Hernia Repair: A Systematic Review and Meta-analysis

BACKGROUND

Parastomal hernia repairs (PHRs) are often complex and challenging, even for experienced abdominal wall surgeons. Although the ideal therapeutic option in the setting of a parastomal hernia is to restore intestinal continuity, this is often not feasible, and numerous techniques have been described for PHR. Current guidelines recommend using mesh for elective PHR, but there is a scarcity of evidence comparing different PHR techniques. We aimed to report a meta-analysis comparing the outcomes of the "Sugarbaker" and "Keyhole" mesh configuration in PHR.

METHODS

A literature search of PubMed, Embase, Scopus, and Cochrane Library databases was performed to identify studies comparing Sugarbaker and Keyhole mesh configuration in PHR. Postoperative outcomes were assessed by means of pooled analysis and meta-analysis. Statistical analysis was performed using RevMan 5.4. Heterogeneity was assessed with I2 statistics.

RESULTS

A total of 3247 studies were screened, and 27 were fully reviewed. Ten studies and 632 patients were included in the meta-analysis. Three hundred five patients (48.3%) with Keyhole and 327 patients (51.7%) with Sugarbaker mesh configuration. Four hundred thirty-three patients (68.5%) underwent laparoscopic PHR with intraperitoneal onlay mesh. Sugarbaker mesh configuration was associated with lower hernia recurrence compared with Keyhole (odds ratio: 0.39; 95% CI: 0.19-0.83; P = 0.01; I2 = 46%). No differences were seen in overall complications, reoperations, stoma outlet obstruction, mesh infection, and postoperative bleeding.

CONCLUSION

PHR with Sugarbaker mesh configuration is associated with decreased hernia recurrence compared with Keyhole and had similar rates of overall complications, reoperations, stoma outlet obstruction, mesh infection, and postoperative bleeding.

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.

Laparoscopic treatment of ventral hernias: the Italian national guidelines

Primary and incisional ventral hernias are significant public health issues for their prevalence, variability of professional practices, and high costs associated with the treatment In 2019, the Board of Directors of the Italian Society for Endoscopic Surgery (SICE) promoted the development of new guidelines on the laparoscopic treatment of ventral hernias, according to the new national regulation. In 2022, the guideline was accepted by the government agency, and it was published, in Italian, on the SNLG website. Here, we report the adopted methodology and the guideline's recommendations, as established in its diffusion policy. This guideline is produced according to the methodology indicated by the SNGL and applying the Grading of Recommendations, Assessment, Development, and Evaluations (GRADE) methodology. Fifteen recommendations were produced as a result of 4 PICO questions. The level of recommendation was conditional for 12 of them and conditional to moderate for one. This guideline's strengths include relying on an extensive systematic review of the literature and applying a rigorous GRADE method. It also has several limitations. The literature on the topic is continuously and rapidly evolving; our results are based on findings that need constant re-appraisal. It is focused only on minimally invasive techniques and cannot consider broader issues (e.g., diagnostics, indication for surgery, pre-habilitation).

Contemporary Outcomes of Elective Parastomal Hernia Repair in Older Adults

Importance

Parastomal hernia is a challenging complication following ostomy creation; however, the incidence and long-term outcomes after elective parastomal hernia repair are poorly characterized.

Objective

To describe the incidence and long-term outcomes after elective parastomal hernia repair.

Design, Setting, and Participants

Using 100% Medicare claims, a retrospective cohort study of adult patients who underwent elective parastomal hernia repair between January 1, 2007, and December 31, 2015, was performed. Logistic regression and Cox proportional hazards models were used to evaluate mortality, complications, readmission, and reoperation after surgery. Analysis took place between February and May 2022.

Exposures

Parastomal hernia repair without ostomy resiting, parastomal hernia repair with ostomy resiting, and parastomal hernia repair with ostomy reversal.

Main Outcomes and Measures

Mortality, complications, and readmission within 30 days of surgery and reoperation for recurrence (parastomal or incisional hernia repair) up to 5 years after surgery.

Results

A total of 17 625 patients underwent elective parastomal hernia repair (mean [SD] age, 73.3 [9.1] years; 10 059 female individuals [57.1%]). Overall, 7315 patients (41.5%) underwent parastomal hernia repair without ostomy resiting, 2744 (15.6%) underwent parastomal hernia repair with ostomy resiting, and 7566 (42.9%) underwent parastomal hernia repair with ostomy reversal. In the 30 days after surgery, 676 patients (3.8%) died, 7088 (40.2%) had a complication, and 1740 (9.9%) were readmitted. The overall adjusted 5-year cumulative incidence of reoperation was 21.1% and was highest for patients who underwent parastomal hernia repair with ostomy resiting (25.3% [95% CI, 25.2%-25.4%]) compared with patients who underwent parastomal hernia repair with ostomy reversal (18.8% [95% CI, 18.7%-18.8%]). Among patients whose ostomy was not reversed, the hazard of repeat parastomal hernia repair was the same for patients whose ostomy was resited vs those whose ostomy was not resited (adjusted hazard ratio, 0.93 [95% CI, 0.81-1.06]).

Conclusions and Relevance

In this study, more than 1 in 5 patients underwent another parastomal or incisional hernia repair within 5 years of surgery. Although this was lowest for patients who underwent ostomy reversal at their index operation, ostomy resiting was not superior to local repair. Understanding the long-term outcomes of this common elective operation may help inform decision-making between patients and surgeons regarding appropriate operative approach and timing of surgery.

Parastomal hernia repair: a five-year experience from a single centre in the UK

Parastomal hernias can affect significantly quality of life in patients who often had underwent major operations. The incidence and recurrence is still high although many techniques have been introduced to improve outcomes. Hence, there is still no agreement on what procedure has better results when it comes to repairing a parostomal hernia. Our aim is to compare outcomes of laparoscopic and open parastomal hernia repair in terms of recurrence, reoperations, post-operative complications and length of stay. Sixty-three parastomal hernia repairs were performed in a single Colorectal Centre over a period of 4 years. Eighteen procedures were performed laparoscopically and 45 open. All the 7 emergency procedures were approached open. Both the techniques showed to be safe with post-operative major complication rate (Clavien-Dindo III or above) of 9.52%. The laparoscopic group was found to have a shorter length of stay (p = 0.04) and earlier start of stoma function (p = 0.01), more uneventful recoveries (0.02) and less minor post-operative complications (Clavien-Dindo I or II-p = 0.01,) but similar recurrence rate (p = 0.41). In the open group, the placement of a mesh showed to reduce the rate of recurrence (p = 0.0001). However, this was not found in the laparoscopic approach. In conclusion, the laparoscopic approach showed do give less post-operative complications and a shorter length of stay, with no benefit in the recurrence rate. Considering the open technique, the use of a mesh seemed to reduce the rate of recurrence.

Mesh erosion into the colon following repair of parastomal hernia: A case report

BACKGROUND

In recent years, mesh has become a standard repair method for parastomal hernia surgery due to its low recurrence rate and low postoperative pain. However, using mesh to repair parastomal hernias also carries potential dangers. One of these dangers is mesh erosion, a rare but serious complication following hernia surgery, particularly parastomal hernia surgery, and has attracted the attention of surgeons in recent years.

CASE SUMMARY

Herein, we report the case of a 67-year-old woman with mesh erosion after parastomal hernia surgery. The patient, who underwent parastomal hernia repair surgery 3 years prior, presented to the surgery clinic with a complaint of chronic abdominal pain upon resuming defecation through the anus. Three months later, a portion of the mesh was excreted from the patient’s anus and was removed by a doctor. Imaging revealed that the patient’s colon had formed a t-branch tube structure, which was formed by the mesh erosion. The surgery reconstructed the structure of the colon and eliminated potential bowel perforation.

CONCLUSION

Surgeons should consider mesh erosion since it has an insidious development and is difficult to diagnose at the early stage.

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.

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.

Sugarbaker Versus Keyhole Repair for Parastomal Hernia: a Systematic Review and Meta-analysis of Comparative Studies

INTRODUCTION

Parastomal hernia is a debilitating complication of stoma creation. Parastomal hernia repair with mesh reduces recurrence rates in open and laparoscopic settings. Recent comparative studies conflict with previously pooled data on optimal mesh repair technique. The objective of this study is to examine parastomal hernia recurrence rates after Sugarbaker and keyhole repairs by performing an updated systematic review and meta-analysis of comparative studies.

METHODS

A systematic review of PubMed, MEDLINE, EMBASE, the Cochrane database, SCOPUS, and the PROSPERO registry was performed according to PRISMA 2020 guidelines (PROSPERO ID: CRD42021290483). Studies comparing parastomal hernia recurrences after Sugarbaker and keyhole repairs were included. Studies with overlapping patient cohorts (duplicate data), non-comparative studies, studies that did not report the primary outcome of interest, and studies not in the English language were excluded. Study bias was assessed using the Newcastle-Ottawa scale. Pooled mean differences (MD), odds ratios (OR), and risk ratios (RR) with 95% confidence intervals (CI) were calculated. Heterogeneity was assessed using the I² statistic. Forest plots and funnel plots were generated. Study quality was analyzed using MINORS. Additional subgroup analysis of modern studies was performed.

RESULTS

Ten comparative studies published between 2005 and 2021 from 5 countries were included for analysis comprising 347 Sugarbaker repairs and 246 keyhole repairs. There were no differences in patient age, sex, or BMI between the groups. There was no difference between the groups regarding surgical site infection (OR 0.78; CI 0.31-1.98; P = 0.61) or post-operative bowel obstruction (OR 0.76; CI 0.23-2.56; P = 0.66). Sugarbaker repairs were significantly less often associated with parastomal hernia recurrence when compared to keyhole repairs (OR 0.38; CI 0.18-0.78; P = 0.008). There was no significant heterogeneity among the studies comparing parastomal hernia recurrence (I² = 32%; P = 0.15). Quality analysis revealed a median MINORS score of 11 (range 6-16). Subgroup analysis of studies performed after the previously published pooled analysis (2015-2021) revealed no significant difference in parastomal hernia recurrence between the two groups (OR 0.58; CI 0.24-1.38; P = 0.22) with a significant subgroup effect (P = 0.05).

CONCLUSIONS

Though there were lower rates of parastomal hernia recurrence with Sugarbaker repairs on overall analysis, this phenomenon disappeared on subgroup analysis of modern studies. Randomized controlled trials with contemporary cohorts would help further evaluate these repairs and minimize potential bias.

Robotic hernia surgery IV. English version : Robotic parastomal hernia repair. Video report and preliminary results

The surgical treatment of parastomal hernias is considered complex and is known to be prone to complications. Traditionally, this condition was treated using relocation techniques or local suture repairs. Since then, several mesh-based techniques have been proposed and are nowadays used in minimally invasive surgery. Since the introduction of robot-assisted surgery to the field of abdominal wall surgery, several adaptations to these techniques have been made, which may significantly improve patient outcomes. In this contribution, we provide an overview of available techniques in robot-assisted parastomal hernia repair. Technical considerations and preliminary results of robot-assisted modified Sugarbaker repair, robot-assisted Pauli technique, and minimally invasive use of a funnel-shaped mesh in the treatment of parastomal hernias are presented. Furthermore, challenges in robot-assisted ileal conduit parastomal hernia repair are discussed. These techniques are illustrated by photographic and video material. Besides providing a comprehensive overview of robot-assisted parastomal hernia repair, this article focuses on the specific advantages of robot-assisted techniques in the treatment of this condition.

Case of laparoscopic parastomal hernia repair using modified Sugarbaker mesh method

A 75-year-old woman underwent sigmoid colon resection and transverse colostomy for perforation of the diverticulum of the sigmoid colon at 70 years of age at another hospital. She was referred to our hospital with complaints of abdominal discomfort 3 months prior to presentation. Abdominal computed tomography revealed a parastomal hernia (PSH). We performed laparoscopic repair using the Sugarbaker approach with a Symbotex Composite Mesh™ and laparoscopic adhesive intestinal repair. The patient’s post-operative course was unremarkable, and she was transferred to the Department of Internal Medicine after 10 days. There was no recurrence 6 months after surgery. Tension-free surgery using a mesh has been reported to be effective in preventing the recurrence of PSH. We performed a laparoscopic modified Sugarbaker mesh method using the Symbotex Composite Mesh™ with collagen film to repair an abdominal hernia.

A Case of Perforated Cholecystitis into a Parastomal Hernia

INTRODUCTION

Parastomal hernia is a common complication following an enterostomy. Gallbladder herniation into parastomal hernia is rare and may become symptomatic and inflamed and very rarely can lead to gallbladder perforation. We present the first case of gallbladder perforation inside a parastomal hernia with a unique skin change. Case Description. In this report, an 87-year-old female with a history of previous open cystectomy and ileal conduit formation, presented with right upper quadrant pain and worsening parastomal swelling. A computed tomography scan showed a parastomal herniation of the gallbladder, cholelithiasis, and possible early acute cholecystitis. Within 12 hours of admission, bile staining skin changes developed around her urostomy site which raised our suspicion of a perforated gallbladder. Biliary peritonitis was confirmed on laparoscopy the same day. We proceeded with an open midline cholecystectomy without hernia repair. The patient was well at her last follow-up. Discussion. A literature review found 14 published cases of incarcerated gallbladder hernia. This uncommon condition mainly affects elderly females. Ten cases were managed operatively, and four cases were managed nonoperatively, with good outcomes. Currently, no consensus on treatment guidelines exists. In a frail elderly patient, a nonoperative approach may be suitable. Operative management was indicated in this case due to clinical concerns of perforation due to developing skin changes. This cutaneous sign has not been previously documented in the literature.

CONCLUSION

While rare, the gallbladder can herniate and become incarcerated inside a parastomal hernia. Bile staining of the skin should raise clinical suspicion of perforation. Management options depend on patient and pathology factors and can be nonoperative or operative, with or without hernia repair.

A new hernia: Meckel's diverticulum within a parastomal hernia

A Meckel's diverticulum is a true diverticulum containing all layers of bowel wall. An infrequently encountered sequela of this is a Littre's hernia, typically inguinal or femoral. This is the first description of a Meckel's diverticulum within a parastomal hernia. When encountered incidentally at surgery, resection should be considered on a case-by-case basis to prevent future complications of bleeding, obstruction or perforation.

Modified keyhole plus technique with partial release of posterior rectus sheath for parastomal hernia repair after ileal conduit

Parastomal hernia (PH) is a common complication of ileal conduit diversions. The Sugarbaker technique has a lower recurrence rate than the keyhole (KH) technique and is typically preferred. However, it may not be feasible in some cases because of anatomical features including the length of the conduit and torsion of the ureter. An 80-year-old woman with complaints of abdominal distention was diagnosed with PH 5 years after radical cystectomy. Computed tomography revealed a 90 × 20-mm muscular layer defect on the cranial side of the ileal conduit. Therefore, we performed the KH technique with intracorporeal closure of the defect using a relief incision of the posterior rectus sheath, avoiding the possibility of torsion of the ureteral ileal anastomosis. No hernia recurrence was observed at postoperative 10 months. The proposed KH plus technique may be an effective method for PH after ileal conduit diversion, thus preventing urinary complications.

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.
