Abstract
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.

Abstract
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.

Abstract
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.

Abstract
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.

Abstract
INTRODUCTION To assess the prophylactic effect of simultaneous placement of mesh and the incidence of parastomal hernia (PSH) after abdominoperineal resection of rectal cancer. METHODS This study included real-world data of 56 surgically resected patients with colorectal cancer who were consecutively assigned to two groups: control (no mesh, n = 32) and experimental (received mesh, n = 24). An artificial patch was placed under the tunica vaginalis of rectus abdominis for patients in the experimental group, whereas those in the control group received routine sigmoidostomy. The median follow-up time was >20 mo. The difference in hazards function was analyzed by cox regression analysis. The Kaplan-Meir analysis was used to determine the survival curves. A P value of <0.05 was considered as significant. RESULTS The postoperative incidence rate of PSH was lower in the experimental (41.7%) group than in the control group (71.9%; P = 0.045). The PSH postoperative time in the experimental group was significantly delayed compared to the control group (48 mo versus 10 mo; P < 0.001). The risk of progression from H1 to H2 was less in the experimental group compared to the control group (49.28% versus 60.86%; P = 0.14). CONCLUSIONS Prophylactic mesh placement significantly prolonged postoperative time for the recurrence of PSH. The incidence of recurrence of H2 (severe PSH) requiring secondary surgical repair was also reduced.

Abstract
BACKGROUND A parastomal hernia (PSH) is an enlargement of the stoma's original opening through the abdominal wall's musculature around a colostomy, ileostomy, or urostomy. Its incidence can be up to 48%. The described methods for its repair have high recurrence rate.This article presents a 3-dimensional silo technique for PSH repair (PSH-R). The aims of this technique are to enhance the structural strength of the tunnel wall, to reinforce both the sidewalls and the fascia above and below the muscular opening, and to maintain a stable stoma opening. METHODS All consecutive patients undergoing PSH-R with the silo technique between January 2009 and May 2018 by 2 plastic surgeons were included. The outcome parameters of interest were hernia recurrence and wound-related complications. RESULTS This study reports 22 patients (9 male, 13 female) with a mean age of 66.7 years and an average body mass index of 29.2. The variety of ostomy types included 10 colostomies, 7 ileostomies, and 5 urostomies. Postoperatively, there were 3 surgical site infections, 1 seroma, and 2 wound healing delays. Six patients were readmitted, 3 of those because of small bowel obstruction. These 3 cases all required reoperation, in addition to 1 operative revision for stoma retraction. During our average follow-up of 19.9 months, 3 cases of PSH recurrence were diagnosed for a recurrence rate of 13.6%. CONCLUSIONS This silo technique is associated with favorable complication and low recurrence rates compared with the available techniques in surgical literature. In our practice, it has established itself as a new and safe technique for complex or recurrent PSHs and should be considered in a surgeon's armamentarium. This technique has become our standard for treatment of recurrent PSHs.

Abstract
AIM Parastomal hernia (PSH) is a common problem following colostomy. Using prophylactic mesh during end colostomy creation may reduce PSH incidence, but concerns exist regarding the optimal type of mesh, potential long-term complications, and cost-effectiveness of its use. We evaluated the cost-effectiveness of mesh prophylaxis to prevent PSH in patients undergoing end colostomy creation for rectal cancer. METHODS We developed a decision-analytical model, stratified by rectal cancer stages I-IV, to estimate the lifetime costs, quality-adjusted life-years (QALYs) and net monetary benefits (NMBs) of synthetic, biologic and no mesh from a UK NHS perspective. We pooled the mesh-related relative risks of PSH from 13 randomised controlled trials (RCTs) and superimposed these on the baseline (no mesh) risk from a population-based cohort. Uncertainty was assessed in sensitivity analyses. RESULTS Synthetic mesh was less costly and more effective than biologic and no mesh to prevent PSH for all rectal cancer stages. At the willingness-to-pay threshold of £20,000/QALY, the incremental NMBs (95% CI) ranged between £1,706 (£1,692 to £1,720) (stage I) and £684 (£678 to £690) (stage IV) for synthetic versus no mesh, and £2,038 (£1,997 to £2,079) (stage I) and £1,671 (£1,653 to £1,689) (stage IV) for synthetic versus biologic mesh. Synthetic mesh was more cost-effective than no mesh unless the relative risk of PSH was ≥0.95 for stages I-III and ≥0.93 for stage IV. [Correction added on 05 October 2021 after first online publication: The estimation of health outcomes (QALYs) for all three interventions evaluated (synthetic mesh; biologic mesh; no mesh) have been corrected in this version.] CONCLUSIONS: Synthetic mesh was the most cost-effective strategy to prevent the formation of PSH in patients after end colostomy for any rectal cancer stage; however, conclusions are dependent on which subset of RCTs are considered to provide the most robust evidence.

Abstract
Introduction Parastomal hernia is a type of incisional hernia occurring in abdominal integuments in the vicinity of a stoma. The best surgical approach for PSH remains controversial. Most studies report short follow-up time after surgery and a low number of cases to allow conclusions. Actually, we don't have a relevant recommendation about an optimal surgical technique or the most effective mesh for PSH repair. Presentation of the case Once packaged the latero-lateral mechanical anastomosis to restore the continuity of the intestinal tract of the patient, an adequate disinfection of trough of the stoma was done. The lateral and medial margins of the defect are then transposed towards each other and kept side by side with a gripper; a 60 mm tristaple linear stapler was placed, incorporating both edges and the charge is fired to obtain a perfect synthesis of the retromuscular plane. Discussion In the literature has been described several surgical techniques for its repair: suture repair, relocation, mesh-based technique with open or laparoscopic approach. Both, the simple corrective surgery of Thorlakson in 1965 and the use of the peritoneomuscular flap for closing the defect, suggested by Bewes, led to high incidence of recurrence. An important reduction in the rate of parastomal hernia derives also from the mesh reinforcement of the stoma trephine. Conclusion The authors suggest that this technique should be help the surgeons to repair parastomal hernia in patients with multiple risk factors to develop a recurrence of parastomal hernia. The best surgical approach for Parastomal Hernia repair (PSH) remains controversial. Causes that predispose to the development of incisional hernia are multiple, such as obesity and diabetes. This technique may help the surgeons to repair the PSH in patients with risk factors to develop a recurrence after surgery.

Abstract
Parastomal hernia (PSH) is one of the most known complications to end colostomies. However, PSH containing the stomach is rare: not many case reports were found in literature search. This case is a 92-year-old woman who was brought in by ambulance to the accident and emergency department with vomiting, abdominal distension, palpable mass on the left side of her abdomen and with reduced stoma effluent. Her abdominal CT scan showed a PSH containing a partially incarcerated gastric hernia. Although there are only few similar cases of PSH containing the stomach reported in the literature, an almost similar pattern in presentation of this unique case can be deduced following a thorough comparison of cases in the literature, which can be quite helpful both academically and clinically: they are often advanced in age and are usually women with end colostomies.

Abstract
Bioprosthetic materials based on mammalian pericardium tissue are the gold standard in reconstructive surgery. Their application range covers repair of rectovaginal septum defects, abdominoplastics, urethroplasty, duraplastics, maxillofacial, ophthalmic, thoracic and cardiovascular reconstruction, etc. However, a number of factors contribute to the success of their integration into the host tissue including structural organization, mechanical strength, biocompatibility, immunogenicity, surface chemistry, and biodegradability. In order to improve the material's properties, various strategies are developed, such as decellularization, crosslinking, and detoxification. In this review, the existing issues and long-term achievements in the development of bioprosthetic materials based on the mammalian pericardium tissue, aimed at a wide-spectrum application in reconstructive surgery are analyzed. The basic technical approaches to preparation of biocompatible forms providing continuous functioning, optimization of biomechanical and functional properties, and clinical applicability are described.

Purpose: Parastomal hernia is a common complication of an enterostoma. Current methods of repair have high recurrence rates and are associated with severe complications. Autologous full-thickness skin as reinforcement may reduce the recurrence and complication rates. This study aims to investigates the tensile strength of full-thickness skin; information that is essential if we are to proceed with clinical trials on humans. Methods: Full-thickness skin samples from 12 donors were tested for tensile strength, as well as the load tolerated by a suture through the skin. Strips of skin were cut out and stretched until breaking point. Sutures were made through skin samples and traction applied until either the tissue or the suture gave way. All done while recording the forces applied using a dynamometer. Identical tests were carried out on commercially available synthetic and biologic graft material for comparison. Results: The full-thickness skin strips had a median tensile strength of 604 N/cm. This tensile strength was significantly higher than that of the compared materials evaluated in this study. In full-thickness skin, the suture, or tissue endured a median force of 67 N before giving way, which was as high as, or higher than similar sutures through the compared materials. Conclusions: The tensile strength of full-thickness skin vastly exceeds the physiological forces affecting the abdominal wall, and sutures through skin endure high loads before giving way. The tensile strength of a full-thickness skin graft and the strength of sutures through this material will not limit its use for reinforcement in parastomal hernia repair.

Abstract
After formation of a permanent terminal stoma by enterostomy, parastomal hernia (PSH) occurs in up to 80% of cases and leads to a wide variety of symptoms and complications with a high rate of emergency operations due to incarceration (ca. 15%). Consequently, greater consideration should be given to PSH prevention even as early as the time of enterostomy and generously applied indications for elective repair of manifest PSH. The aim of this article is to summarize and evaluate the current evidence for PSH repair and prevention. Poor postoperative results after attempted repair of manifest PSH with slit meshes in different layers of the abdominal wall shift the focus onto stoma lateralization (sandwich and Sugarbaker techniques) or 3‑dimensional tunnel-shaped implants with meshes to cover the stomal edges. To date, the best strategy for PSH prevention has still not been defined and techniques with slit meshes show different results. Nevertheless, 10 prospective randomized trials, meta-analyses, a Cochrane review and guidelines from the European Hernia Society (EHS) about various slit-mesh devices in sublay, onlay and intraperitoneal positions confirmed significantly reduced rates of PSH after mesh augmentation compared to conventionally sutured enterostomy without morbidity associated with the implanted material. Despite the positive data situation PSH prevention is seldom performed in daily practice, which is due to uncertainty surrounding the most suitable surgical strategy, the necessity to spend additional time at the end of a demanding operation, the aversion to implanting meshes into a contaminated operative field and the lack of remuneration of preventive surgical procedures. Future trials should, therefore, no longer compare standard enterostomy techniques with one prevention method in general but should have a new focus on techniques providing adequate results in PSH repair (Sugarbaker, sandwich and 3‑D tunnel meshes), probe the advantages and evaluate the differences in outcome between these strategies.

Abstract
Introduction Conventional surgery for parastomal hernia entails primary suture repair or stoma relocation. Laparoscopic surgery has advantages of less pain, faster post-operative recovery and better cosmesis. While the Sugarbaker technique has been valued for least recurrences, however, it exposes the stomal loop to the parietal surface of the mesh exposing it to complications. We report a modification of mesh placement after primary defect repair to improvise the safety of meshplasty and to minimise mesh erosions into the stomal loop of bowel. Patients and Methods Patients with permanent stoma presenting with a parastomal bulge leading to difficulty with stoma care or abdominal distention or pain were included in the study. A pre-operative computed tomography scan was performed in all patients to rule out any recurrence of primary pathology for which stoma was created and to study the abdominal musculature and defects. Results Of 14 patients, 12 patients had end-sigmoid stoma, one had end ileostomy following surgery for ulcerative colitis and one had urinary conduit. The size of the defect varied from 4.5 cm to 6 cm in diameter, and the average duration of surgery was 125 min. Pain assessed on VAS score was higher in the first 12 h, and all were started on orals on the next day, and average hospital stay was 4.2 days. The longest follow-up of 7 years and shortest of 15 months did not reveal any complications as recurrence, seroma, mesh infections or erosions into the stoma. Conclusion Modified placement of composite mesh is safe and helps in minimising mesh-related complications of the Sugarbaker technique for parastomal hernias.

Abstract
AIM To retrospectively evaluate the safety and feasibility of a new modified laparoscopic Sugarbaker repair in patients with parastomal hernias.
METHODS A retrospective study was performed to analyze eight patients who underwent parastomal hernia repair between June 2016 and January 2018. All of these patients received modified laparoscopic Sugarbaker hernia repair treatment. This modified technique included an innovative three-point anchoring and complete suturing technique to fix the mesh. All procedures were performed by a skilled hernia surgeon. Demographic data and perioperative outcomes were collected to evaluate the safety and efficacy of this modified technique.
RESULTS Of these eight patients, two had concomitant incisional hernias. All the hernias were repaired by the modified laparoscopic Sugarbaker technique with no conversion to laparotomy. Three patients had in-situ reconstruction of intestinal stoma. The median mesh size was 300 cm2, and the mean operative time was 205.6 min. The mean postoperative hospitalization time was 10.4 d, with a median pain score of 1 (visual analog scale method) at postoperative day 1. Two patients developed postoperative complications. One patient had a pocket of effusion surrounding the biologic mesh, and one patient experienced an infection around the reconstructed stoma. Both patients recovered after conservative management. There was no recurrence during the follow-up period (6-22 mo, average 13 mo).
CONCLUSION The modified laparoscopic Sugarbaker repair could fix the mesh reliably with mild postoperative pain and a low recurrence rate. The technique is safe and feasible for parastomal hernias.

Abstract
BACKGROUND A temporary loop ileostomy, which is used to decrease the risk of symptomatic anastamotic leakage after anterior resection and total mesorectal excision (TME), is traditionally closed without any mesh. However, as 44% of incisional site hernias need further repair after stoma closure, attention has increasingly been paid to the use of mesh. Research on the prevention of these hernias is scarce, and no studies comparing different meshes exist. METHOD/DESIGN The Preloop trial (Clinical Trials NCT03445936) is a prospective, randomized, controlled, multicenter trial to compare synthetic mesh (Parietene Macro™, Medtronic, Minneapolis, MN, USA) and biological implants (Permacol™, Medtronic) at a retromuscular sublay position for the prevention of incisional site hernias after loop-ileostomy closure. The main endpoints in this trial are infections at 30-day follow-up and the incidence of hernias clinically or on CT scan at 10 months after closure of the stoma. The secondary endpoints are other complications within 30 days of surgery graded with the Clavien-Dindo classification, reoperation rate, operating time, length of stay, quality of life measured with RAND-36, and incidence of hernia over a 5-year follow-up period. A total of 100 patients will be randomized in a 1:1 ratio. DISCUSSION This is a pilot trial that will be undertaken to provide some novel evidence on the safety profile and efficiency of both synthetic mesh and biological implants for the prevention of incisional hernias after closure by temporary loop ileostomy. The hypothesis is that synthetic mesh is economical but equally safe and at least as effective as biological implants in hernia prevention and in contaminated surgical sites.

Abstract
Patients with end colostomy often undergo multiple operations because of high incidence and recurrence rates of parastoml hernia. Therefore, it is particularly important to prevent the occurrence of parastomal hernia when undergoing an end colostomy. Using a prophylactic mesh, which is developed and gradually recognized in recent years, is one of the methods to prevent parastomal hernia. Here, we review the application and new advances in prophylactic mesh placement in end colostomy.

Abstract
AIM The Association of Coloproctology of Great Britain and Ireland (ACPGBI) Delphi process identified prevention and treatment of parastomal hernia (PSH) as the second highest priority non-cancer related colorectal pathology. This position statement aims to summarize the current evidence base. METHODS Four broad themes were identified (prevention, diagnosis/classification, management and operative repair). Guidelines are based on evidence from an extensive literature review using organized searches on the PubMed, MEDLINE, Embase and Cochrane databases. The Grading of Recommendations Assessment, Development and Evaluation (GRADE) system was adhered to for classifying the quality of evidence and reporting the strength of recommendations. RESULTS The suture repair of PSH other than for patients in extremis is not recommended. Synthetic non-absorbable mesh can be used safely in the short term in the construction of colostomies post rectal surgery, but longer-term follow-up is needed. Other broad recommendations are made around access to stoma care nurses, prevention classification and management. CONCLUSION There is a lack of high quality evidence for many domains in the prevention and treatment of PSH but the results of several studies are awaited. WHAT DOES THIS PAPER ADD TO THE LITERATURE?: Parastomal hernias are a common and debilitating condition following stoma formation. This position statement from ACPGBI details the current evidence base and ongoing research for the prevention, diagnosis and management of parastomal hernias.

Abstract
INTRODUCTION Although many surgeons have adopted the use of biologic and biosynthetic meshes in complex abdominal wall hernia repair, others have questioned the use of these products. Criticism is addressed in several review articles on the poor standard of studies reporting on the use of biologic meshes for different abdominal wall repairs. The aim of this consensus review is to conduct an evidence-based analysis of the efficacy of biologic and biosynthetic meshes in predefined clinical situations. METHODS A European working group, "BioMesh Study Group", composed of invited surgeons with a special interest in surgical meshes, formulated key questions, and forwarded them for processing in subgroups. In January 2016, a workshop was held in Berlin where the findings were presented, discussed, and voted on for consensus. Findings were set out in writing by the subgroups followed by consensus being reached. For the review, 114 studies and background analyses were used. RESULTS The cumulative data regarding biologic mesh under contaminated conditions do not support the claim that it is better than synthetic mesh. Biologic mesh use should be avoided when bridging is needed. In inguinal hernia repair biologic and biosynthetic meshes do not have a clear advantage over the synthetic meshes. For prevention of incisional or parastomal hernias, there is no evidence to support the use of biologic/biosynthetic meshes. In complex abdominal wall hernia repairs (incarcerated hernia, parastomal hernia, infected mesh, open abdomen, enterocutaneous fistula, and component separation technique), biologic and biosynthetic meshes do not provide a superior alternative to synthetic meshes. CONCLUSION The routine use of biologic and biosynthetic meshes cannot be recommended.

Abstract
Parastomal hernia repair remains a significant surgical challenge. Recurrence after standard "keyhole" or primary suture repair is common. We adopted and modified a new technique using a construct shaped like an inverted top hat. We review our experience over the last six years in the first 30 patients (31 consecutive procedures). Of these 31 procedures, six (19%) resulted in a parastomal hernia recurrence with a median follow-up of 31 months (range 0.5-80). Four of the recurrences occurred in our initial experience, when we constructed the top hat of xenograft alone. When the technique was modified, using a synthetic composite mesh for the underlay portion of the hat, there were only two subsequent recurrences in 16 patients (13%) with a median follow-up of 22 months. One of these "recurrences" was secondary to infection of the top hat construct, which had to be removed. This initial success in preventing recurrence of parastomal hernia is probably due to the design of the construct, for it occludes the vulnerable stoma/fascial angle, through which most parastomal hernia recurrences occur.

Abstract
AIM To outline current evidence regarding prevention and treatment of parastomal hernia and to compare use of synthetic and biologic mesh.
METHODS Relevant databases were searched for studies reporting hernia recurrence, wound and mesh infection, other complications, surgical techniques and mortality. Weighted pooled proportions (95%CI) were calculated using StatsDirect. Heterogeneity concerning outcome measures was determined using Cochran’s Q test and was quantified using I2. Random and fixed effects models were used. Meta-analysis was performed with Review Manager software with the statistical significance set at P ≤ 0.05.
RESULTS Forty-four studies were included: 5 reporting biologic mesh repairs; 21, synthetic mesh repairs; and 18, prophylactic mesh repairs. Most of the studies were retrospective cohorts of low to moderate quality. The hernia recurrence rate was higher after undergoing biologic compared to synthetic mesh repair (24.0% vs 15.1%, P = 0.01). No significant difference was found concerning wound and mesh infection (5.6% vs 2.8%; 0% vs 3.1%). Open and laparoscopic techniques were comparable regarding recurrences and infections. Prophylactic mesh placement reduced the occurrence of a parastomal hernia (OR = 0.20, P < 0.0006) without increasing wound infection [7.8% vs 8.2% (OR = 1.04, P = 0.91)] and without differences between the mesh types.
CONCLUSION There is no superiority of biologic over synthetic mesh for parastomal hernia repair. Prophylactic mesh placement during the initial surgery significantly reduces parastomal hernia occurrence regardless of the mesh type.

Abstract
BACKGROUND International guidelines on the prevention and treatment of parastomal hernias are lacking. The European Hernia Society therefore implemented a Clinical Practice Guideline development project. METHODS The guidelines development group consisted of general, hernia and colorectal surgeons, a biostatistician and a biologist, from 14 European countries. These guidelines conformed to the AGREE II standards and the GRADE methodology. The databases of MEDLINE, CINAHL, CENTRAL and the gray literature through OpenGrey were searched. Quality assessment was performed using Scottish Intercollegiate Guidelines Network checklists. The guidelines were presented at the 38th European Hernia Society Congress and each key question was evaluated in a consensus voting of congress participants. RESULTS End colostomy is associated with a higher incidence of parastomal hernia, compared to other types of stomas. Clinical examination is necessary for the diagnosis of parastomal hernia, whereas computed tomography scan or ultrasonography may be performed in cases of diagnostic uncertainty. Currently available classifications are not validated; however, we suggest the use of the European Hernia Society classification for uniform research reporting. There is insufficient evidence on the policy of watchful waiting, the route and location of stoma construction, and the size of the aperture. The use of a prophylactic synthetic non-absorbable mesh upon construction of an end colostomy is strongly recommended. No such recommendation can be made for other types of stomas at present. It is strongly recommended to avoid performing a suture repair for elective parastomal hernia. So far, there is no sufficient comparative evidence on specific techniques, open or laparoscopic surgery and specific mesh types. However, a mesh without a hole is suggested in preference to a keyhole mesh when laparoscopic repair is performed. CONCLUSION An evidence-based approach to the diagnosis and management of parastomal hernias reveals the lack of evidence on several topics, which need to be addressed by multicenter trials. Parastomal hernia prevention using a prophylactic mesh for end colostomies reduces parastomal herniation. Clinical outcomes should be audited and adverse events must be reported.

Abstract
INTRODUCTION There is a continuous concern about meshes used in laparoscopic inguinal hernia repair, which mainly relates to their biocompatibility and ability to decrease postoperative complications and recurrence rate; in other words, efforts are made to find the "ideal" prosthesis. OBJECTIVES To evaluate different prostheses used in laparoscopic inguinal hernia repair in terms of biocompatibility, postoperative complications, recurrence rate and quality of life, so that all the features could lead us to the "ideal" mesh. MATERIAL AND METHOD Randomized controlled trials, reviews, prospective and retrospective studies, retrospective cross-sectional and experimental studies on animals published between 2000 and 2016 were analysed with respect to several features of a mesh: biocompatibility, postoperative complications, recurrence rate and quality of life. OUTCOMES The most common comparison is between heavy-weight and light-weight mesh used in laparoscopic inguinal hernia repair. Experimental studies try to discover the "ideal" prosthesis, which could provide improved biocompatibility, low postoperative complications, decreased recurrence rate and good quality of life. The most commonly used mesh that meats the characteristics of an "ideal" prosthesis is a light-weight monofilament macroporous polypropylene mesh, with a minimum tensile strength >16 N/cm², measuring 10x15 cm. CONCLUSIONS Published data show that the "ideal" prosthesis used in laparoscopic inguinal hernia repair has not been discovered yet. Regarding heavy- or light-weight meshes, there is no significant effect on recurrence, acute or chronic pain, incidence of seroma or return to daily activity and quality of life (1).

The use of a composite synthetic mesh in the vicinity of bowel - For repair and prophylaxis of parastomal hernias. Does it increase the risk of short term infective complications? Int J Surg 2017; 45:67-71. [PMID: 28751222 DOI: 10.1016/j.ijsu.2017.07.077] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/03/2017] [Revised: 07/17/2017] [Accepted: 07/17/2017] [Indexed: 12/21/2022]
Abstract
AIMS The use of synthetic meshes in potentially infected operative fields such as in the vicinity of large bowel, is controversial. This study describes our experience with the use of a synthetic composite mesh for prophylaxis and repair of parastomal hernias. METHODS Data were collected retrospectively over a 7-year period from 2008 to 2015. An IPOM (DynaMesh™) was used either during the formation of the stoma to reinforce the abdominal wall around the stoma or during the surgical repair of existing parastomal hernias, using keyhole or sandwich technique. Majority of meshes were placed laparoscopically. Clinical data and outcomes any stoma wound complications were collected. RESULTS Forty seven patients were included with a male to female ratio of 34:13. Median age was 66 years (38-91 years) with median follow-up of 17 months (3-73 months). Twenty seven patients had a prophylactic mesh placement (PMP) around colostomy after resection of colorectal cancer. None of these patients had any wound complications. Twenty patients had repair of parastomal hernias (RPH). One patient (1/20) in this group had a superficial wound infection around the stoma site and underwent an incision and drainage. One patient developed seroma and one had parastomal wound haematoma. CONCLUSIONS The use of a composite synthetic mesh using a laparoscopic IPOM technique for the prophylaxis and treatment of parastomal hernias, even in a clean contaminated surgical field, is safe and feasible.

Abstract
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.

Abstract
Despite medical and surgical advances leading to increased ability to restore or preserve gastrointestinal continuity, creation of stomas remains a common surgical procedure. Every ostomy results in a risk for subsequent parastomal herniation, which in turn may reduce quality of life and increase health care expenditures. Recent evidence-supported practices such as utilization of prophylactic reinforcement, attention to stoma placement, and laparoscopic-based stoma repairs with mesh provide opportunities to both prevent and successfully treat parastomal hernias.

Abstract
BACKGROUND Over the years, various open and laparoscopic approaches toward the repair of parastomal hernias (PSH) have been described. The variety of published techniques itself can be seen as an indicator for the often low level of satisfaction reached with the surgical procedures. METHODS From January 1999 to January 2014, we assessed all cases of PSH repair performed at the three participating surgical departments in a retrospective analysis. The results were evaluated with regard to different surgical techniques focusing on complications and recurrences. RESULTS One hundred and thirty-five individuals could be included in the analysis. They were operated on with eight different surgical techniques. Laparoscopic procedures were carried out in 46.7 % (63/135) of the cases. Median follow-up was 54 months (12-146 months). We found 44 cases of recurrence (32.6 %) and 24 (17.8 %) of the patients experienced perioperative complications and 12 of them needed to return to theater. Fourteen of the 135 patients (10.4 %) were operated as emergency cases which were associated with a mortality of 28.6 % (4/14). In case of elective PSH repair, no mortality occured. CONCLUSION The results achieved by direct suture or the use of incised flat meshes for the repair of PSH were poor with these procedures having unacceptably high recurrence rates. With regard to the latter ostomy revision through three-dimensional funnel-shaped meshes and the laparoscopic sandwich technique showed the best results. Emergency procedures were linked to a dramatic increase in morbidity and mortality (p < 0.001).

Abstract
Background: Parastomal hernias (PSHs) are a frequent complication and remain a surgical challenge. We present a new option for single-port PSH repair with equilateral stoma relocation using preshaped, prosthetic 3-dimensional implants and flat mesh insertion in intraperitoneal onlay placement for additional augmentation of the abdominal wall. Methods: We describe our novel technique in detail and performed an analysis of prospectively collected data from patients who underwent single-port PSH repair, focusing on feasibility, conversions, and complications. Results: From September 2013 to January 2014, 9 patients with symptomatic PSHs were included. Two conversions to reduced-port laparoscopy using a second 3-mm trocar were required because of difficult adhesiolysis, dissection, and reduction of the hernia sac content. No major intra- or postoperative complications or reoperations were encountered. One patient incurred a peristomal wound healing defect that could be treated conservatively. Conclusion: We found that single-port PSH repair using preshaped, elastic 3-dimensional devices and additional flat mesh repair of the abdominal wall is feasible, safe, and beneficial, relating to optimal coverage of unstable stoma edges with wide overlap to all sides and simultaneous augmentation of the midline in the IPOM technique. The stoma relocation enables prolapse treatment and prevention. The features of a modular and rotatable multichannel port system offer benefits in clear dissection ongoing from a single port. Long-term follow-up data on an adequate number of patients are awaited to examine efficacy.

Abstract
PURPOSE The optimal technique and mesh type for parastomal hernia repair have yet to be ascertained. Biologic meshes have been advocated in parastomal hernia repair due to purported resistance to infection in contaminated fields. The aim of this study was to evaluate the effectiveness of additionally cross-linked acellular porcine dermal collagen mesh (Permacol) for onlay parastomal hernia repair. METHODS A retrospective review of case notes, and abdominal CT scans when available, was performed for consecutive patients who had a parastomal hernia repaired between January 2007 and May 2010. All hernias were repaired with onlay placement of the biologic mesh. Hernias were classified according to the Moreno-Matias classification where CT scans were available. RESULTS Over a 34-month period, 30 consecutive patients, median age 74 years, 17 female, underwent parastomal hernia repair using onlay biologic mesh. There were 23 paracolostomy and seven paraileostomy hernias. The hernia was primary in 26 patients. Pre-operative CT scans were available in 18 patients (Moreno-Matias Type 1 = 1, Type 2 = 4, Type 3 = 13). There was one perioperative death, and 29 patients were available for follow-up, and median duration of follow-up (either CT or clinical) was 36 months (range 3-79). Twenty-six patients developed recurrence of the parastomal hernia (89.6%), and median time to recurrence was 10 months (range 3-72),with Moreno-Matias Type 1 = 0, Type 2 = 4, Type 3 = 14, unknown = 8. Fifteen out of 26 patients have had repairs of the recurrence using a variety of techniques. Of these, 10 patients have had further recurrence. CONCLUSION Onlay repair of parastomal hernia with cross-linked porcine dermal collagen biologic mesh reinforcement has poor long-term outcomes with unacceptably high recurrence rates and should not be performed.

Abstract
Introduction In the field of hernia prevention, the prophylactic mesh-reinforcement of stoma-sites is one of the most controversially discussed issues. The incidence of parastomal hernias in the literature reported to be up to 48.1% after end colostomy and up to 30.8% after loop of colostomy, but still remains uncertain due to diagnostic variety of clinical or radiological methods, heterogeneous patient groups and variable follow-up intervals. Anyway, the published data regarding the use of synthetic or bio-prostethic meshes in the prevention of parastomal hernia at the primary operation are very scarce. Methods A literature search of the Medline database in terms of biological prophylactic mesh implantation in stoma creation identified six systematic reviews, two randomized controlled trials (RCT), two case-controlled studies, and one technical report. Results In a systematic review focusing on the prevention of parastomal hernia including only RCTs encompassing one RCT using bio-prosthetic mesh the incidence of herniation was 12.5% compared to 53% in the control group (p < 0.0001). In one RCT and two case-control studies, respectively, there was a significant smaller incidence of parastomal herniation as well as a similar complication rate compared to the control group. Only in one RCT, no significant difference regarding the incidence of parastomal hernia was reported with comparable complication rates. Conclusion Thus, so far two RCT and two case-control studies are published with prophylactic bio-prosthetic reinforcement in stoma sites. The majority revealed significant better results in terms of parastomal herniation and without any mesh-related complications in comparison to the non mesh group. Further, multicenter RCT are required to achieve a sufficient level of recommendation.

Laparoscopic parastomal hernia repair: No different than a laparoscopic ventral hernia repair? Surg Endosc 2015; 30:1542-6.

Abstract
BACKGROUND Parastomal hernia (PH) is a common complication when a stoma is used. The high incidence (35-50%) and patient longevity have created a situation where patients are being referred for consideration of repair with more frequency. Due to the presence of an ostomy and the increased bacterial contamination of the area, the insertion of a prosthetic material is concerning for complications. Laparoscopic repair of parastomal hernias utilizing a modified Sugarbaker technique has been demonstrated to have excellent outcomes. The purpose of this study is to demonstrate that laparoscopic PH repair has outcomes similar to laparoscopic ventral hernia (LVH) repair without the presence of a stoma. METHODS After obtaining institutional review board approval, patients with parastomal hernia who underwent laparoscopic repair using Sugarbaker technique between 2009 and 2012 were compared to patients with ventral hernias who underwent LVH repair in a retrospective review, with a match of 1:3. Data collected included demographics, comorbidities, operative time, defect size, and mesh size. Outcomes and complications were compared between the two groups. RESULTS Twenty patients underwent Sugarbaker repair, and these cases were compared to 60 patients with ventral hernia that received LVH repair. There was no statistically significant difference in age, BMI, smoking status, ASA score, defect size, or mesh size between groups. Operative time was significantly longer in the PH group: 172 ± 35 versus the LVH group: 94 ± 32 min (p < 0.1). Length of stay was longer, 3 days (3-5.5) for PH versus 1 day (1-2.8) for LVH, p < 0.1. The two groups did not differ in terms of wound complications or recurrence, with a median follow-up of 37 days (IQ range 27-518). CONCLUSION The Sugarbaker technique is as safe as LVH repair with no more complications given the presence of a stoma.

Abstract
Development of parastomal hernias (PH) is very common after stoma formation and carries a risk of subsequent bowel incarceration, obstruction and strangulation. The management of PH remains a challenge for the colorectal surgeon, and there are currently no standardized guidelines for the treatment of PH. Even more difficult is the management of complex parastomal hernias (CPH). We conducted a review of the literature to identify recent developments in the treatment of CPH, including analysis of the use of synthetic and biologic mesh prostheses, method of mesh placement and surgical approach.

Abstract
Parastomal hernia is one of the most common complications following stoma creation and its prevalence is only expected to increase. It often leads to a decrease in the quality of life for patients due to discomfort, pain, frequent ostomy appliance leakage, or peristomal skin irritation and can result in significantly increased healthcare costs. Surgical technique for parastomal hernia repair has evolved significantly over the past two decades with the introduction of new types of mesh and laparoscopic procedures. The use of prophylactic mesh in high-risk patients at the time of stoma creation has gained attention in lieu of several promising studies that have emerged in the recent days. This review will attempt to demonstrate the burden that parastomal hernias present to patients, surgeons, and the healthcare system and also provide an overview of the current management and surgical techniques at both preventing and treating parastomal hernias.

Abstract
Parastomal hernia is a prevalent problem and treatment can pose difficulties due to significant rates of recurrence and morbidities of the repair. The current standard of care is to perform parastomal hernia repair with mesh whenever possible. There exist multiple options for mesh reinforcement (biologic and synthetic) as well as surgical techniques, to include type of repair (keyhole and Sugarbaker) and position of mesh placement (onlay, sublay, or intraperitoneal). The sublay and intraperitoneal positions have been shown to be superior with a lower incidence of recurrence. This procedure may be performed open or laparoscopically, both having similar recurrence and morbidity results. Prophylactic mesh placement at the time of stoma formation has been shown to significantly decrease the rates of parastomal hernia formation.

Abstract
Parastomal hernia formation and ostomy prolapse are relatively common complications of intestinal ostomy construction. Underlay mesh placement with lateralization of the stoma limb appears to be the method of repair with the lowest recurrence rate. Prophylaxis of new stomas with mesh is advocated by many authors. We report the case of an 81-year-old man with chronic steroid-dependent COPD who presented to the emergency department with strangulated small bowel evisceration 9 days following completion abdominal colectomy, and creation of an end ileostomy reinforced with intraperitoneal mesh. This rare complication was related to this patient's risk factors for poor healing including poor nutrition, age, chronic COPD and coughing and steroid dependence with immunosuppression.

Abstract
Soft-tissue reconstruction for a variety of surgical conditions, such as abdominal wall hernia or pelvic organ prolapse, remains a challenge. There are numerous meshes available that may be simply categorized as either synthetic or biologic. Within biologic meshes, porcine dermal meshes have come to dominate the market. This review examines the current evidence for their use and the limitations of knowledge. Although there is increasing evidence to support their safety, long-term follow-up studies that support their efficacy are lacking. Numerous clinical trials that remain ongoing may help elucidate their precise role in soft-tissue reconstruction.

Abstract
Background. Implantation of synthetic meshes for reinforcement of abdominal wall hernias can be complicated by mesh infection, which often requires mesh explantation. The risk of mesh infection is increased in a contaminated environment or in patients who have comorbidities such as diabetes or smoking. The use of biological prostheses has been advocated because of their ability to resist infection. Initial results, however, have shown high hernia recurrence rates and wound occurrences. The objective of the present study is to evaluate early and mid-term outcomes in the largest French series that included 43 consecutive complex abdominal hernias repaired with biological prostheses. Materials and methods. Retrospective observational study of a prospective collected data bank. Patient demographics, history of previous repairs, intraoperative findings and degree of contamination, associated procedures, postoperative prosthetic-related complications, and long-term results were retrospectively reviewed. Results. There were 25 (58%) incisional, 14 parastomal, and 4 midline hernia repairs. Hernias were considered “clean” (n = 5), “clean-contaminated” (n = 19), “contaminated” (n = 12), or “dirty” (n = 7). Wound-related morbidity occurred in 17 patients; 4 patients needed reoperation for cutaneous necrosis or abscess. Smoking was the only risk factor associated with wound complication ( P = .022). No postoperative wound events required removal of the prosthesis. There were 4 hernia recurrences (9%). A previous attempt at repair ( P = .018) and no complete fascia closure ( P = .033) were associated with hernia recurrence. Conclusions. This study demonstrated that the use of bioprothesis in complex hernia repair allowed successful single-stage reconstruction. Wound-related complications were frequent. Cost-benefit analyses are important to establish the validity of these findings.

Abstract
Hernia emergencies are commonly encountered by the acute care surgeon. Although the location and contents may vary, the basic principles are constant: address the life-threatening problem first, then perform the safest and most durable hernia repair possible. Mesh reinforcement provides the most durable long-term results. Underlay positioning is associated with the best outcomes. Components separation is a useful technique to achieve tension-free primary fascial reapproximation. The choice of mesh is dictated by the degree of contamination. Internal herniation is rare, and preoperative diagnosis remains difficult. In all hernia emergencies, morbidity is high, and postoperative wound complications should be anticipated.

Fascia lata allografts as biological mesh in abdominal wall repair: preliminary outcomes from a retrospective case series. Plast Reconstr Surg 2013; 132:631e-639e.

Abstract
BACKGROUND The use of biological meshes in management of infected abdominal hernias or in abdominal fields at high risk of infection (potentially contaminated or with relevant comorbidities) is well established. Available products include xenogenic patches or decellularized dermal allografts. Despite their biomechanical features, banked fascial allografts have not been investigated yet in this setting. The authors evaluated the safety and effectiveness of banked fascia lata allografts as biological meshes in abdominal wall repair. METHODS A consecutive series of patients affected by abdominal wall defects and who were candidates for repair by means of a biological mesh and treated in the authors' institution with banked fascia lata allografts were reviewed retrospectively. Data from clinical and instrumental follow-up evaluations up to 48 months (average, 23 months) were analyzed. RESULTS Twenty-one patients (aged 1 to 86 years) with abdominal wall defects resulting from traumatic (n = 1), neoplastic (n = 6), or multiple previous laparotomies (n = 14) were treated from January of 2008 to October of 2012. Operations had no relevant postoperative complications. At clinical/instrumental follow-up examinations, no major signs of recurrence, laxity, infection of grafts, or other related pathologic symptoms were recorded. Three patients suffered from temporary minor complications (e.g., wound seroma, partial cutaneous dehiscence). At instrumental (computed tomographic scan or magnetic resonance imaging) evaluations, the neofascial tissue appeared stable until medium-term follow-up (3 to 6 months), later being gradually degraded and apparently replaced by host tissue. CONCLUSION According to limited preliminary outcomes, banked fascia lata allografts seem to provide a biocompatible, safe, and effective alternative to other biological meshes. CLINICAL QUESTION/LEVEL OF EVIDENCE Therapeutic, IV.

Abstract
PURPOSE A clear definition of "complex (abdominal wall) hernia" is missing, though the term is often used. Practically all "complex hernia" literature is retrospective and lacks proper description of the population. There is need for clarification and classification to improve patient care and allow comparison of different surgical approaches. The aim of this study was to reach consensus on criteria used to define a patient with "complex" hernia. METHODS Three consensus meetings were convened by surgeons with expertise in complex abdominal wall hernias, aimed at laying down criteria that can be used to define "complex hernia" patients, and to divide patients in severity classes. To aid discussion, literature review was performed to identify hernia classification systems, and to find evidence for patient and hernia variables that influence treatment and/or prognosis. RESULTS Consensus was reached on 22 patient and hernia variables for "complex" hernia criteria inclusion which were grouped under four categories: "Size and location", "Contamination/soft tissue condition", "Patient history/risk factors", and "Clinical scenario". These variables were further divided in three patient severity classes ('Minor', 'Moderate', and 'Major') to provide guidance for peri-operative planning and measures, the risk of a complicated post-operative course, and the extent of financial costs associated with treatment of these hernia patients. CONCLUSION Common criteria that can be used in defining and describing "complex" (abdominal wall) hernia patients have been identified and divided under four categories and three severity classes. Next step would be to create and validate treatment algorithms to guide the choice of surgical technique including mesh type for the various complex hernias.
