Evaluating postoperative hernia incidence and risk factors following pelvic exenteration.

Pelvic exenteration (PE) is a technically challenging surgical procedure. More recently, quality of life and survivorship following PEs are being increasingly acknowledged as important patient outcomes. This includes evaluating major long-term complications such as hernias, defined as the protrusion of internal organs through a facial defect (The PelvEx Collaborative in Br J Surg 109:1251-1263, 2022), for which there is currently limited literature. The aim of this paper is to ascertain the incidence and risk factors for postoperative hernia formation among our PE cohort managed at a quaternary centre. METHOD: A retrospective cohort study examining hernia formation following PE for locally advanced rectal carcinoma and locally recurrent rectal carcinoma between June 2010 and August 2022 at a quaternary cancer centre was performed. Baseline data evaluating patient characteristics, surgical techniques and outcomes was collated among a PE cohort of 243 patients. Postoperative hernia incidence was evaluated via independent radiological screening and clinical examination. RESULTS: A total of 79 patients (32.5%) were identified as having developed a hernia. Expectantly, those undergoing flap reconstruction had a lower incidence of postoperative hernias. Of the 79 patients who developed postoperative hernias, 16.5% reported symptoms with the most common symptom reported being pain. Reintervention was required in 18 patients (23%), all of which were operative. CONCLUSION: This study found over one-third of PE patients developed a hernia postoperatively. This paper highlights the importance of careful perioperative planning and optimization of patients to minimize morbidity.

Postoperative perineal hernia repair: what is the evidence?

The present study determined the characteristics of perineal hernia treatment in the literature, and the incidence of postoperative recurrence was stratified according to repair techniques. A systematic search of the available literature on the treatment of postoperative perineal hernias was performed using a major database. The types of repair techniques and outcome were entered into an electronic database and a pooled analysis was performed. A total of 213 cases of postoperative perineal hernia repair were collected from 20 relevant articles in the literature after excluding case reports (n < 3). Synthetic mesh was the material used most frequently for perineal hernia repair (55.9%). The most frequently used approach in perineal hernia repair was the perineal approach (56.5%). The recurrence rate was highest with the use of biological mesh (40.4%) and the perineal approach (35.6%). The recurrence rate was lowest in the combined abdominal & perineal approach (0%), followed by the abdominal approach (8.8%) and the laparoscopic approach (11.8%). A number of different repair techniques have been described in the literature. The use of synthetic mesh via a combined abdominal-perineal approach or intraabdominal/laparoscopic approach was shown to be associated with a reduced postoperative recurrence rate.

Prophylactic Parastomal Mesh Sublay at the Time of Ileal Conduit: Surgical Technique.

OBJECTIVE: To demonstrate the surgical technique for prophylactic mesh placement in the sublay position during ileal conduit creation because literature suggests that prophylactic mesh placement at the time of cystectomy may reduce the risk of parastomal hernias with low risk of mesh-related complications. Parastomal hernias are one of the most common complications following ileal conduit construction and occur in 17-65% of patients undergoing cystectomy with urinary diversion. Review of our institutions data demonstrated a high incidence of hernias associated with ileal conduits, which have substantial burden to patients, surgeons, and the healthcare system. METHODS: This is a retrospective chart review of data from a single surgeon who performed cystectomy with ileal conduit for 12 patients with bladder cancer between January, 2021-March, 2022 at our institution. These dates were chosen based on the timing of availability of literature suggesting a benefit from prophylactic mesh placement. Preliminary data was analyzed determine the incidence of parastomal hernia and mesh-related complications. RESULTS: A total of 12 patients underwent cystectomy with ileal conduit between January, 2021-March, 2022 at our institution. Eleven patients (92%) had prophylactic mesh placed during their procedure. Median follow up was 5.4 months (0.8-8 months). Two patients (17%) developed a parastomal hernia which was detected clinically and/or radiographically. The hernias occurred in patients with mesh and within 6 months of cystectomy. One patient had stomal stenosis eventually requiring surgical revision. There were no mesh infections or mesh removals. CONCLUSION: Parastomal hernias are a common and morbid complication of ileal conduit urinary diversion. Our early experience demonstrates that the procedure is straightforward, adds little time to the surgical procedure, and is associated with a low complication rate. Our experience is too small and follow up too short to confirm that the results of the randomized trial can be matched at our center.

Association between pelvic floor disorders and hernias.

INTRODUCTION AND HYPOTHESIS: Connective tissue disorders may contribute to pelvic floor disorders (PFDs). Like PFDs, abdominal wall hernias are more common in patients with systemic connective tissue disorders. We conducted this study to explore the possible association between PFDs and hernias in adult women. METHODS: We obtained the data for this study from a study of PFDs among parous women. At enrollment, stress urinary incontinence (SUI), overactive bladder (OAB), and anal incontinence (AI) were assessed using the Epidemiology of Prolapse and Incontinence Questionnaire (EPIQ) and pelvic organ prolapse (POP) was assessed through the Pelvic Organ Prolapse Quantification (POP-Q) examination. Participants were asked to report hernia surgery and list their hernia types. We compared the prevalence of PFDs in those with and without hernias using chi-square test. We used multiple regression analysis to adjust for obstetric and sociodemographic variables. RESULTS: Among 1529 women, 79 (5.2%) reported history of hernia surgery. The prevalence of POP was 7.6% (6 cases) vs. 7.4% (107 cases), the prevalence of SUI was 7.6% (6 cases) vs. 9.9% (144 cases), the prevalence of OAB was 7.6% (6 cases) vs. 5.7% (83 cases), and the prevalence of AI was 7.6% (6 cases) vs. 10.8% (156 cases) in those with hernias compared to those without hernias, respectively. None of these differences were statistically significant. There was no association between hernias and PFDs after adjustment for type of delivery, number of deliveries, age group, primary racial background, weight category, and smoking status. CONCLUSION: In this study, we could not find any association between hernias and PFDs.

A retrospective study of internal small bowel herniation following pelvic lymphadenectomy for gynecologic carcinomas.

After pelvic lymphadenectomy (PLA), pelvic vessels, nerve, and ureter are skeletonized. Internal hernias beneath the skeletonized pelvic structure following pelvic lymphadenectomy (IBSPP) are a rare complication following PLA. To the best of our knowledge, only 12 IBSPP cases have been reported and clinical details on such hernias remain unknown. The aim of the study was to investigate the incident and etiology of IBSPP. 1313 patients who underwent open or laparoscopic pelvic lymphadenectomy were identified from our database. A retrospective review was performed. Mean follow-up period was 33.9 months. A total of 12 patients had IBSPP. Multivariate analysis of laparoscopic surgeries group as compared to open surgeries group, para-aortic lymphadenectomy rate, number of dissected lymph nodes by PLA, antiadhesive material use rate, and blood loss were lower in laparoscopic surgeries group: odd ratio (OR) = 0.13 [95% confidence interval (CI) 0.08-0.19], and OR = 0.70 [95% CI 0.50-0.99], OR = 0.17 [95% CI 0.10-0.28], OR = 0.93 [95% CI 0.92-0.94]. However, no significant difference was observed in the incidence of IBSPP between laparoscopic surgery (1.0%) and open surgery (0.8%). All IBSPP occurred in the right pelvic space. These findings may contribute to the development of prevention methods for this disease.

Incidence of acute postoperative robotic port-site hernias: results from a high-volume multispecialty center.

Fascial closure at 8-mm robotic port sites continues to be controversial. As the use of the robotic platform increases across multiple abdominal specialties, there are more case reports describing reoperation and small bowel resection for acute port-site hernias. A retrospective review of all robotic abdominal surgeries performed from 2012 to 2019 at NYU Langone Medical Center was conducted. Patients who had a reoperation in our facility within 30 days were identified, and medical records reviewed for indications for reoperation and findings. The study included 11,566 patients, of which 82 patients (0.71%) underwent a reoperation related to the index robotic surgery within 30 days. Fifteen of 11,566 patients (0.13%) had acute port-site hernias, and 3 of these 15 patients required small bowel resection. Eleven of 15 acute port-site hernias (73%) were at 8-mm robotic port site, 2 of which required a small bowel resection. More than a third of the patients had a hernia at an 8-mm port site where a surgical drain had been placed. Considering that each robotic case, regardless of specialty, has three ports at a minimum, the true incidence of acute postoperative robotic port-site hernia is 0.032% (11/34,698), with the incidence of concomitant small bowel resection being 0.006% (2/34,698). The incidence of acute port-site hernias from 8-mm robotic ports is exceedingly low across specialties. Our results do not support routine fascial closure at 8-mm robotic port sites due to an extremely low incidence. However, drain sites require special consideration.

Post-cystectomy Enterocele: A Case Series and Review of the Literature.

OBJECTIVE: To present a case series and literature review on post radical cystectomy (RC) pelvic organ prolapse (POP) to heighten awareness of the symptoms, imaging findings, and risk factors associated with this complication and discuss opportunities for prevention. Women with muscle invasive bladder cancer undergo RC with anterior exenteration, significantly disrupting the pelvic floor. These women are at risk for POP. METHODS: We present 4 cases of high-grade POP in women who underwent RC for bladder cancer. We reviewed the literature by conducting a Boolean search in PubMed with the terms "("radical cystectomy") AND ("enterocele" OR "pelvic organ prolapse" OR "rectocele" OR "vaginal vault prolapse")." RESULTS: All 4 women reported a bulge sensation in the vagina and physical exam confirmed POP. Three had radiographic findings consistent with high-grade enterocele at rest. Three experienced prolonged intra-abdominal pressure rise post-RC that may have further weakened pelvic floor support, while the fourth had a history of surgery for high-grade POP. Nine articles on POP following RC were identified. Four focused on treatment and 3 focused on prevention. CONCLUSION: Administration of a single validated question would have identified all 4 cases of postoperative enterocele and is sensitive to detect most women who are experiencing POP. Attention to the pelvic floor on cross-sectional imaging with identification of features that indicate POP, such as herniation of intestinal contents below the pubo-coccygeal line, will identify and/or confirm high-grade enterocele. Familiarity with risk factors for POP and identification of weakened vaginal wall support opens up the opportunity for prevention.

Surgical emergencies during SARS-CoV-2 pandemic lockdown: what happened?

OBJECTIVE: The pandemic from SARS-CoV-2 is having a profound impact on daily life of a large part of world population. Italy was the first Western country to impose a general lockdown to its citizens. Implications of these measures on several aspects of public health remain unknown. The aim of this study was to investigate the effects of the lockdown on surgical emergencies volumes and care in a large, tertiary referral center. MATERIALS AND METHODS: Electronic medical records of all patients visited in our Emergency Department (ED) and admitted in a surgical ward from February 21st 2020 to May 3rd 2020 were collected, analyzed and compared with the same periods of 2019 and 2018 and a cross-sectional study was performed. RESULTS: Number of surgical admissions dropped significantly in 2020 with respect to the same periods of 2019 and 2018, by almost 50%. The percentage distribution of admissions in different surgical wards did not change over the three years. Time from triage to operating room significantly reduced in 2020 respect to 2019 and 2018 (p<0.001). CONCLUSIONS: The lockdown in Italy due to SARS-CoV-2 pandemic arguably represents the largest social experiment in modern times. Data provided by our study provide useful information to health authorities and policymakers about the effects of activity restriction on surgical accesses and changing epidemiology due to an exceptional external event.

A low incidence of perineal hernia when using a biological mesh after extralevator abdominoperineal excision with or without pelvic exenteration or distal sacral resection in locally advanced rectal cancer patients.

BACKGROUND: Extralevator abdominoperineal excision (ELAPE), abdominoperineal excision (APE) or pelvic exenteration (PE) with or without sacral resection (SR) for locally advanced rectal cancer leaves a significant defect in the pelvic floor. At first, this defect was closed primarily. To prevent perineal hernias, the use of a biological mesh to restore the pelvic floor has been increasing. The aim of this study, was to evaluate the outcome of the use of a biological mesh after ELAPE, APE or PE with/without SR. METHODS: A retrospective study was conducted on patients who had ELAPE, APE or PE with/without SR with a biological mesh (Permacol™) for pelvic reconstruction in rectal cancer in our center between January 2012 and April 2015. The endpoints were the incidence of perineal herniation and wound healing complications. RESULTS: Data of 35 consecutive patients [22 men, 13 women; mean age 62 years (range 31-77 years)] were reviewed. Median follow-up was 24 months (range 0.4-64 months). Perineal hernia was reported in 3 patients (8.6%), and was asymptomatic in 2 of them. The perineal wound healed within 3 months in 37.1% (n = 13), within 6 months in 51.4% (n = 18) and within 1 year in 62.9% (n = 22). In 17.1% (n = 6), the wound healed after 1 year. It was not possible to confirm perineal wound healing in the remaining 7 patients (20.0%) due to death or loss to follow-up. Wound dehiscence was reported in 18 patients (51.4%), 9 of whom needed vacuum-assisted closure therapy, surgical closure or a flap reconstruction. CONCLUSIONS: Closure of the perineal wound after (EL)APE with a biological mesh is associated with a low incidence of perineal hernia. Wound healing complications in this high-risk group of patients are comparable to those reported in the literature.

Extraction bags provide no benefit when compared to unprotected lateral stomach extraction during laparoscopic sleeve gastrectomy.

BACKGROUND: Currently, no evidence compares outcomes for techniques utilizing surgical specimen extractions bags versus unprotected extraction. METHODS: Evaluation of sleeve gastrectomies performed at two high-volume centers. Cases where an extraction bag was used (+EB) were compared to bag-less extraction (-EB). Outcomes included operative contamination, surgical site infections and extraction-site hernias. RESULTS: 674 patients were evaluated (417 in the +EB group and 257 in the -EB group). Preoperative characteristics were similar between groups. There was a trend toward shorter operative times with the -EB group (-EB = 100 min vs + EB = 106 min, p = 0.07). Gross spillage was documented as a contaminated case in 0.4% of -EB cases compared to 1.2% in +EB cases (p = 0.51). Two superficial infections were appreciated (1.2% = +EB vs 0.7% = -EB, p = 0.7) with one post-operative abscess in the -EB group (p = 0.61). One post-operative hernia was seen in each group (p = 0.62). DISCUSSION: Bag-less extraction is a safe, resource conscious method that may potentially decreased operative time.

Prophylactic biological mesh reinforcement versus standard closure of stoma site (ROCSS): a multicentre, randomised controlled trial.

BACKGROUND: Closure of an abdominal stoma, a common elective operation, is associated with frequent complications; one of the commonest and impactful is incisional hernia formation. We aimed to investigate whether biological mesh (collagen tissue matrix) can safely reduce the incidence of incisional hernias at the stoma closure site. METHODS: In this randomised controlled trial (ROCSS) done in 37 hospitals across three European countries (35 UK, one Denmark, one Netherlands), patients aged 18 years or older undergoing elective ileostomy or colostomy closure were randomly assigned using a computer-based algorithm in a 1:1 ratio to either biological mesh reinforcement or closure with sutures alone (control). Training in the novel technique was standardised across hospitals. Patients and outcome assessors were masked to treatment allocation. The primary outcome measure was occurrence of clinically detectable hernia 2 years after randomisation (intention to treat). A sample size of 790 patients was required to identify a 40% reduction (25% to 15%), with 90% power (15% drop-out rate). This study is registered with ClinicalTrials.gov, NCT02238964. FINDINGS: Between Nov 28, 2012, and Nov 11, 2015, of 1286 screened patients, 790 were randomly assigned. 394 (50%) patients were randomly assigned to mesh closure and 396 (50%) to standard closure. In the mesh group, 373 (95%) of 394 patients successfully received mesh and in the control group, three patients received mesh. The clinically detectable hernia rate, the primary outcome, at 2 years was 12% (39 of 323) in the mesh group and 20% (64 of 327) in the control group (adjusted relative risk [RR] 0·62, 95% CI 0·43-0·90; p=0·012). In 455 patients for whom 1 year postoperative CT scans were available, there was a lower radiologically defined hernia rate in mesh versus control groups (20 [9%] of 229 vs 47 [21%] of 226, adjusted RR 0·42, 95% CI 0·26-0·69; p<0·001). There was also a reduction in symptomatic hernia (16%, 52 of 329 vs 19%, 64 of 331; adjusted relative risk 0·83, 0·60-1·16; p=0·29) and surgical reintervention (12%, 42 of 344 vs 16%, 54 of 346: adjusted relative risk 0·78, 0·54-1·13; p=0·19) at 2 years, but this result did not reach statistical significance. No significant differences were seen in wound infection rate, seroma rate, quality of life, pain scores, or serious adverse events. INTERPRETATION: Reinforcement of the abdominal wall with a biological mesh at the time of stoma closure reduced clinically detectable incisional hernia within 24 months of surgery and with an acceptable safety profile. The results of this study support the use of biological mesh in stoma closure site reinforcement to reduce the early formation of incisional hernias.

Population-based rates of hernia surgery in Ghana.

PURPOSE: To estimate the population-based annual rate of hernia surgery in Ghana, so as to better define the met and unmet need and to identify opportunities to decrease the unmet need. METHODS: Data on operations performed from June 2014 to May 2015 were obtained from representative samples of 48 of 124 district (first-level) hospitals, 9 of 11 regional (referral) hospitals, and 3 of 5 tertiary hospitals, and scaled-up to nationwide estimates. Rates of hernia surgery were compared to previously published annual incidence of symptomatic hernia in Ghana (210/100,000 population) and to published annual rates of hernia surgery in high-income countries (120-275/100,000). RESULTS: Estimated 17,418 [95% uncertainty interval (UI) 8154-26,683] hernia operations were performed nationally. The annual rate of hernia operations was 65 operations/100,000 population (95% UI 30.2-99.0). The rate was considerably less than the annual incidence of new symptomatic hernia or rates of hernia surgery in high-income countries. Hernia operations represented 7.5% of all operations. Most hernia operations (74%) were performed at district hospitals. Most district hospitals (54%) did not have fully trained surgeons, but nonetheless performed 38% of district-level hernia operations. CONCLUSIONS: The rate of hernia operations fell short of estimated need. Most hernia repairs were performed at district hospitals, many without fully trained surgeons. Future global surgery benchmarking needs to address both overall surgical rates as well as rates for specific highly important operations. Countries can strengthen their planning for surgical care by defining their total, met, and unmet need for hernia surgery.

The Prevalence and Characteristics of Untreated Hernias in Southwest Cameroon.

BACKGROUND: Hernias are one of the most commonly encountered surgical conditions, and every year, more than 20 million hernia repairs are performed worldwide. The surgical management of hernia, however, is largely neglected as a public health priority in developing countries, despite its cost-effectiveness. To date, the prevalence and impact of hernia have not been formally studied in a community setting in Cameroon. The aim of this study was to determine the prevalence and characteristics of untreated hernia in the Southwest region of Cameroon. METHODS: This study was a subanalysis of a cross-sectional community-based survey on injury in Southwest Cameroon. Households were sampled using a three-stage cluster sampling method. Household representatives reported all untreated hernias occurring in the past year. Data on socioeconomic factors, hernia symptoms, including the presence of hernia incarceration, and treatment attempts were collected between January 2017 and March 2017. RESULTS: Among 8065 participants, 73 persons reported symptoms of untreated hernia, resulting in an overall prevalence of 7.4 cases per 1000 persons (95% confidence limit 4.98-11.11). Groin hernias were most commonly reported (n = 49, 67.1%) and predominant in young adult males. More than half of persons with untreated hernia (56.7%) reported having symptoms of incarceration, yet 42.1% (n = 16) of these participants did not receive any surgical treatment. Moreover, 21.9% of participants with untreated hernias never presented to formal medical care, primarily because of the high-perceived cost of care. Untreated hernias caused considerable disability, as 21.9% of participants were unable to work because of their symptoms, and 15.1% of households earned less money. CONCLUSIONS: Hernia is a significant surgical problem in Southwest Cameroon. Despite over half of those with unrepaired hernias reporting symptoms of incarceration, home treatment and nonsurgical management were common. Costs associated with formal medical services are a major barrier to obtaining consultation and repair. Greater awareness of hernia complications and cost restructuring should be considered to prevent disability and mortality due to hernia.

[Emergency surgery in Russian Federation (in Russian only)]. / Sostoianie ékstrennoi khirurgicheskoi pomoshchi v Rossiiskoi Federatsii.

In the following article, we present the key trends in emergency surgical care in the Russian Federation between 2000 and 2017. The study used data from federal statistical observations and a survey of state medical institutions in 80 regions encompassing 99.3% of the country's population. We discovered a change in the correlation between acute abdominal diseases, particularly a significant reduction in the occurrence of acute appendicitis and perforated peptic ulcer. Reduction in the number of emergency surgeries by 27.8% annually was also observed. Mortality rate decreased in cases of strangulated hernia, acute cholecystitis and acute pancreatitis, while it is stable for bowel obstruction and acute appendicitis and increasing in perforated peptic ulcer cases. The total annual number of lethal outcomes due to acute abdominal diseases was decreased by 1900 cases. Significant changes were observed in mortality rate and minimally invasive surgeries proportions between federal districts and individual regions of the country. The range of administrative measures was proposed.

Optimizing Care for Ugandans with Untreated Abdominal Surgical Conditions.

BACKGROUND: Abdominal operations account for a majority of surgical volume in low-income countries, yet population-level prevalence data on surgically treatable abdominal conditions are scarce. OBJECTIVE: In this study, our objective was to quantify the burden of surgically treatable abdominal conditions in Uganda. METHODS: In 2014, we administered a two-stage cluster-randomized Surgeons OverSeas Assessment of Surgical Need survey to 4,248 individuals in 105 randomly selected clusters (representing the national population of Uganda). FINDINGS: Of the 4,248 respondents, 185 reported at least one surgically treatable abdominal condition in their lifetime, giving an estimated lifetime prevalence of 3.7% (95% CI: 3.0 to 4.6%). Of those 185 respondents, 76 reported an untreated condition, giving an untreated prevalence of 1.7% (95% CI: 1.3 to 2.3%). Obstructed labor (52.9%) accounted for most of the 238 abdominal conditions reported and was untreated in only 5.6% of reported conditions. In contrast, 73.3% of reported abdominal masses were untreated. CONCLUSIONS: Individuals in Uganda with nonobstetric abdominal surgical conditions are disproportionately undertreated. Major health system investments in obstetric surgical capacity have been beneficial, but our data suggest that further investments should aim at matching overall surgical care capacity with surgical need, rather than focusing on a single operation for obstructed labor.

Hernias perineales / Perineal hernias

Introducción: Las hernias perineales son excepcionales y predominan ampliamente en el sexo femenino. Se clasifican en anteriores o posteriores según su localización con respecto al músculo transverso del periné. Etiológicamente pueden ser primarias (congénitas o adquiridas), de las cuales se han descrito alrededor de 100 casos, y secundarias sobre todo a operaciones previas (resección adbominoperineal). Objetivo: Actualizar los conocimientos sobre las hernias perineales por lo infrecuente de este padecimiento. Métodos: Se realizó una revisión bibliográfica a partir de la consulta de artículos relacionados con el tema, publicados en Pubmed, Hinari, SciELO y Medline mediante el localizador de información Endnote. Se utilizaron 51 citas para la revisión, 41 de ellas de los últimos cinco años. Se incluyeron tres libros y una cita del propio autor. Conclusiones: Las hernias perineales son extremadamente raras. Existe poca experiencia reportada en la bibliografía, por lo que aún no es posible determinar la mejor forma terapéutica. Pueden abordarse por vía abdominal, perineal o combinada. Las técnicas empleadas son: cierre simple, transposición de colgajos musculares, colocación de mallas y retroflexión del útero o vejiga para cerrar el defecto. Aunque no existe suficiente experiencia, la cirugía laparoscópica se ha utilizado en algunos casos y podría ser la vía de elección en el futuro(AU)

Introduction: Perineal hernias are exceptional and predominate widely in the female sex. They are classified into anterior or posterior, based on their location with respect to the transverse muscle of the perineum. Etiologically speaking, they can be primary (congenital or acquired), of which about 100 cases have been described, and secondary above all to previous operations (abdominoperineal resection). Objective: To update the knowledge about perineal hernias, due to the infrequent nature of this condition. Methods: A literature review was carried out in the articles about the topic and published in Pubmed, Hinari, SciELO and Medline using the Endnote information locator. We used 51 citations for the review, 41 of which belonged to the last five years. Three books and a citation by the author were included. Conclusions: Perineal hernias are extremely rare. There is little experience reported in the literature, so it is not yet possible to determine the best therapeutic form. They can be treated by an abdominal or perineal approach, or combined. The techniques used are: simple closure, transposition of muscle flaps, placement of meshes, and retro-flexion of the uterus or bladder to close the defect. Although there is not enough experience, laparoscopic surgery has been used in some cases and could be the gold standard in the future(AU)

American Society for Metabolic and Bariatric Surgery and American Hernia Society consensus guideline on bariatric surgery and hernia surgery.

The American Society for Metabolic and Bariatric Surgery issues the following guidelines for the purpose of enhancing quality of care in hernia treatment through metabolic and bariatric surgery. In this statement, suggestions for management are presented that are derived from available knowledge, peer-reviewed scientific literature, and expert opinion. This was accomplished by performing a review of currently available literature regarding obesity, obesity treatments, and hernia surgery. The intent of issuing such a guideline is to provide objective information regarding the impact of obesity treatment on effective and durable hernia repair. The guideline may be revised in the future should additional evidence become available.
