Evaluation of Open Rives-Stoppa and Lichtenstein Repair Methods for Bilateral Inguinal Hernias: A Single-Centre Comparative Analysis.

Aim The purpose of the study is to compare the two common open surgical methods for bilateral inguinal hernias: bilateral Lichtenstein repair and Rives-Stoppa repair. It evaluates their benefits, drawbacks, and outcomes to improve the management of bilateral inguinal hernias and enhance patient care and results. Background Abdominal wall hernias are prevalent in the surgical field, and they occur when intra-abdominal organs protrude through weakened or torn regions in the abdominal wall. The Lichtenstein repair, also known as the tension-free mesh repair, is one of the most widely used techniques that involves placing a synthetic mesh over the hernia defect to reinforce the abdominal wall. The Rives-Stoppa technique takes the posterior approach, which involves placing a large mesh in the preperitoneal space, which provides broad coverage of the potential hernia sites. Method This retrospective study included 86 male patients from the Department of General Surgery at Indus Health Network, Karachi, Pakistan. Data were collected up to three months post-operation for all open bilateral inguinal hernia repairs performed between January 2017 and April 2021. The patients were divided into two groups: group A underwent Lichtenstein repair, while group B underwent Rives-Stoppa repair. The procedures were performed by different surgeons and surgical trainees under direct supervision. Results Regarding post-operative complications (scrotal swelling, epididymo-orchitis, seroma formation, ipsilateral testicular swelling, surgical site infection, erectile dysfunction, wound dehiscence, fever, hydrocele, sensory abnormality, hernia recurrence in 3 months, post-operative pain in 14 days), there was no significant difference observed between the two groups. There were two recurrences within three months after Lichtenstein repair and one recurrence after Stoppa repair, but no statistical difference was demonstrated. Conclusion Statistically, both the Lichtenstein repair and the Rives-Stoppa repair demonstrated similar outcomes. However, the Rives-Stoppa repair offers distinct advantages for bilateral inguinal hernia repair, making it a preferable option in many cases as this approach utilises a single midline incision, simultaneously facilitating access to both hernial sites. This method ensures complete coverage of the myopectineal orifices bilaterally, addressing all potential hernia sites in the lower abdomen. These features collectively contribute to the technique's efficacy in managing bilateral hernias.

A Clinical Study of Anterior Abdominal Wall Hernias and Its Management: A Medical College Experience.

Objective We aim to evaluate the various risk factors contributing to the occurrence of anterior abdominal wall hernias and assess the various surgical modalities. Materials and methods This prospective observational research was conducted between 2022 and 2024 at a tertiary care health center, involving 100 participants with an anterior abdominal wall hernia diagnosis aged over 14 years. The study excluded patients under 14 years with bleeding diathesis, inherited coagulopathies, inguinal or femoral hernias, or recurrent ventral hernias. Participants underwent detailed clinical examinations and biochemical evaluationsand underwent a primary ultrasonography (USG)/contrast-enhanced computed tomography (CECT) to determine defect size. Risk factors were documented, including age, gender, occupation, body mass index (BMI), comorbidities, previous surgery history, multiparity, smoking, chronic straining due to constipation or benign prostatic hyperplasia (BPH), malnutrition, chronic steroid use, chronic renal failure, and chronic liver disease. The surgical procedure was determined by the same surgical team for all cases. Standard antibiotic prophylaxis and preoperative painting/draping protocols were followed in all cases. Intraoperatively, intraoperative time (in hours) was documented. Postoperative parameters included pain, hematoma formation, seroma formation, surgical site infections (SSIs), and early recurrence. These intra- and postoperative findingsconstituted the primary outcome parameters. Secondary outcome parameters included hospital stayduration and time taken to return to work. Data analysis was performed using Statistical Package for the Social Sciences (SPSS) version 16 (IBM SPSS Statistics, Armonk, NY) software. Results The study analyzed the occurrence of ventral hernias in 100 patients, with the fourth decade having the highest occurrence (n=42 (42%)). The majority of the participants were male (female: n=47 (47%), male: n=53 (53%)). The majority of the participants were laborers, and 24% (n=24) were office workers. The study found that hypertension, diabetes mellitus, and chronic obstructive pulmonary disease were risk factors for hernias. Other risk factors included obesity, previous history of surgery, multiparity, smoking, chronic straining, malnutrition, and chronic steroid use. The most common type of ventral hernia was umbilical hernia (n=33 (33%)), followed by paraumbilical hernias (n=30 (30%)), and incisional hernias (n=20 (20%)). Of the 100 patients, 74% underwent open hernia repair, with the mean operation time being minimal in cases managed with laparoscopic repair (2.5±0.67 hours). Postoperative painwas highest with the Rives-Stoppa (RS) repair with component separation group. The incidence of surgical site infection was the maximum among cases of open anatomical repair (41.7%), followed by RS repair (31.3%), while it was the minimum in laparoscopic repair (3.7%). Early recurrence was lower in the laparoscopic group (n=1 (3.7%)). Conclusion The study highlights risk factors for abdominal wall hernia and management approaches. Understanding these is crucial for identifying and preventing recurrence. Surgeons must choose the right surgical approach based on patient health and symptoms to achieve desired outcomes and minimize complications. In addition, surgical expertise, availability of resources, and knowledge of what works best for the surgeon constitute important determinants of surgical outcomes.

Rives-Stoppa Repair Versus Bilateral Inguinal Hernioplasty: A Comprehensive Review of Surgical Techniques and Patient Outcomes.

Hernia repair surgery is a common procedure to address the protrusion of organs or tissues through weakened muscles or connective tissue. This review compares two prominent surgical techniques for hernia repair: the Rives-Stoppa repair and bilateral inguinal hernioplasty. The Rives-Stoppa repair involves a posterior approach with extensive mesh placement suitable for complex and recurrent hernias. In contrast, bilateral inguinal hernioplasty focuses on simultaneously repairing bilateral hernias, potentially reducing operative time and enhancing recovery. This review examines each approach's technical aspects, including incision methods, mesh placement, and closure techniques. Patient outcomes, such as postoperative pain, recovery time, recurrence rates, and quality of life, are critically analyzed based on current research and clinical data. Economic considerations are also evaluated, encompassing each technique's cost-effectiveness and economic impact. By synthesizing these findings, this review aims to provide valuable insights for surgeons, healthcare providers, and policymakers in optimizing hernia repair strategies. The evolving landscape of surgical techniques and materials underscores the importance of ongoing research to refine practices and improve outcomes for patients undergoing hernia repair surgery.

Endoscopic enhanced-view totally extraperitoneal prosthetic (eTEP) versus open Rives-Stoppa repair as a treatment of midline abdominal wall hernias with rectus diastasis: comparison of postoperative pain and length of hospital stay in a single-centre surgical cohort.

The Rives-Stoppa (RS) procedure is a gold standard treatment of midline abdominal wall hernias. Comparability of pain control and outcomes to the enhanced-view totally extraperitoneal prosthetic (eTEP) repair remain unclear. A single-centre retrospective surgical cohort was selected including 30 RS repairs (January 2019-November 2021) and 30 consecutive eTEP procedures (September 2021-August 2022) for midline abdominal wall hernia(s) with rectus abdominis diastasis. Postoperative pain and outcomes were compared up to 1month. Presence and median duration of patient-controlled analgesia were, respectively, 90% and 3 nights with RS, versus 30% and 0 nights with eTEP. Median switch to only oral analgesics occurred at postoperative day (POD) 3 after RS and at POD 2 after eTEP. Postoperative analgesics and opioid prescription at discharge were comparable. Median length of hospital stay was six nights after RS versus 3 nights after eTEP. Median duration of surgery was 110.5 and 164.5min for RS and eTEP, respectively. After RS, 30 patients had postoperative drain(s) compared to 3 patients after eTEP. Conversion was needed in 3 eTEP procedures. Postoperative complications were comparable. No early recurrences were observed. Minimal residual diastasis was seen at postoperative consultation in 11 patients after eTEP. Compared to RS, eTEP is a minimally invasive alternative treatment of midline abdominal wall hernias with rectus abdominis diastasis and is associated with a shorter length of hospital stay, less postoperative pain and a comparable risk of short-term complications. At 1month after eTEP, minimal residual diastasis can be present. ClinicalTrials.gov: NCT05446675. Secondary identifying number: EC/EH/220608-SK.Date of Registration: June 24, 2022.

Intraperitoneal Onlay Mesh (IPOM Plus) Repair Versus Extended-View Totally Extraperitoneal Rives-Stoppa (eTEP-RS) Repair in Primary Ventral Hernias: Experience With 50 Cases in a Tertiary Care Hospital.

Background Primary ventral hernias are abnormal protrusions of abdominal viscera through the areas of weakness in the fascia of the abdominal wall. The aim of this study was to compare the benefits and complications, and the overall outcome in the Extended-View Totally Extraperitoneal Rives-Stoppa (eTEP-RS) repair versus Intraperitoneal Onlay Mesh (IPOM Plus) repair in the management of primaryventral hernias. Methods After obtaining institutional ethical committee clearance, this prospective comparative study between IPOM Plus and eTEP-RS was conducted in a tertiary care hospital from December 2020 to January 2022. A total of 50 patients presenting with primary ventral hernias were included in the study, of whom 25 underwent IPOM Plusand 25 underwent eTEP-RS repairs. Group selection was doneby simple randomization using the lottery method. Patients more than 18 years of age with primary ventral hernias presenting with a hernial defect width less than 6 cm, consenting to the study, were included in the study. Patients who did not fulfill the inclusion criteria, strangulated/obstructed hernias, recurrent/incisional hernias, connective tissue disorders, skin infections, enterocutaneous fistulas, pregnancy, morbid obesity, and parastomal hernias were exclusion factors. Results The mean intraoperative duration in the eTEP-RS group (192.3 ± 16.20 min) was significantly higher than in theIPOM Plus group (102.6 ± 16.78min, p=0.001). The mean duration of hospital stay in the IPOM Plus group (5.9 ± 2.19 days) was longer than in the eTEP-RS group (4.6 ± 3.17 days, p=0.02). The mean postoperative pain scores, from the Visual Analogue Scale(VAS), on days 1, 7, and 90 were 3.2 ± 1.11, 2.64 ± 1.11, and 1.68 ± 1.46in the IPOM Plus group and 1.84 ± 0.688, 0.76 ± 0.66 and 0.08 ± 0.40 in the eTEP-RS group, respectively(p=0.001). Conclusion Despite being a technically easy procedure requiring less intraoperative time, IPOM Plus had several disadvantages, such as increased postoperative pain, longer duration of hospital stays, higher chances of wound site seromas, and higher rates of postoperative paralytic ileus.On the other hand, eTEP-RS was a more challenging procedure requiring more intraoperative time; however, it had several advantages: less postoperative pain, less duration of hospital stay, early recovery, and fewer chances of seromasand paralytic ileus.However, more robust data is required to compare and validate the differences between both procedures' short- and long-term outcomes.

Comparative Analysis of Bilateral Open Inguinal Hernia Repair and Rives-Stoppa Repair: A Comprehensive Review.

Inguinal hernias present a significant healthcare burden globally, necessitating effective surgical management. This comprehensive review evaluates two primary surgical techniques for managing bilateral inguinal hernias: bilateral open inguinal hernia and Rives-Stoppa repair. This review aims to provide insights into optimal surgical approaches through a comparative analysis of these techniques, including examining advantages, disadvantages, outcomes, and factors influencing technique selection. Bilateral open inguinal hernia repair offers simplicity and familiarity, while Rives-Stoppa repair may provide advantages such as reduced recurrence rates and postoperative complications. The findings underscore the importance of considering patient-specific factors, surgeon expertise, and hospital resources when selecting the optimal approach. Further research is warranted to conduct long-term comparative studies and explore innovations in surgical techniques and materials, ultimately enhancing patient outcomes and advancing inguinal hernia repair practices.

Comparison of open and endoscopic posterior component separation with transversus abdominis release: a propensity score-matched study.

Posterior component separation with transversus abdominis release (TAR) is considered to be the optimal technique for large incisional ventral hernia repair. Endoscopic TAR (eTAR) that gets all the benefits of minimally invasive surgery (MIS) gives a possibility to enhance results of the treatment. The aim of our study was to make the comparison between open and endoscopic TAR procedures with an emphasis on frequency and severity of postoperative complications in comparable groups. All patients had midline incisional hernia and underwent either open (open TAR group) or endoscopic (eTAR group) Rives-Stoppa repair in combination with bilateral transversus abdominis release in Moscow City Hospital №1 from January 2018 to December 2022. A propensity score matching (PSM) was used to make groups comparable. Postoperative complications were classified according to Clavien-Dindo Classification, and Comprehensive complication index was calculated. We performed 133 open and endoscopic TAR separation for midline incisional hernia. After PSM analysis 51 patients were matched to each group. Overall surgical morbidity in the open TAR group (56.9%) was statistically significantly higher than in the eTAR group (29.4%) (p = 0.009). There were more severe complications (Clavien IIIa-V) in the open TAR group (11.8% vs. 0%, p = 0.027). Length of hospital stay after surgery was shorter in eTAR group (p < 0.001). The Comprehensive complication index in the open TAR group was significantly higher than in eTAR group, 8.7 (0-20.9) vs. 0 (0-8.7) (p = 0.011). Based on the data from our study, the entire MIS procedure including endoscopic TAR is a safe and optimal technique for surgery of midline incisional ventral hernia, requiring TAR separation in terms of reducing the rate of postoperative complications, their severity and hospital length of stay, compared to open TAR procedure.

The Benefit of Open Rives-Stoppa Procedure in Complex Incisional Hernia.

Introduction: Ventral hernia is one of the most common general surgical pathologies. An incisional hernia will develop in 10–15% of patients with an abdominal incision, and the risk increases to up to 23% in those who develop surgical site infections.&#x0D; Ventral hernia repairs are mostly elective (90%) procedures, but the repair methods are highly variable.&#x0D; Popularized in Europe by Rives and Stoppa, the retromuscular technique has proven to be very effective, with a 94.2% probability of having the lowest odds for recurrence and a 77.3% probability of having the lowest odds for SSI.&#x0D; The study aimed to evaluate our experience at a secondary care center performing Rives-Stoppa repair for abdominal ventral and incisional hernias.&#x0D; Materials and Methods: Between April 2019 and August 2021, 46 patients in the practice at a secondary regional hospital, Teni Konomi, Korce, Albania, underwent a Rives-Stoppa incisional hernia repair.&#x0D; Results: There were 14 (31%) males and 32(69%) females (age range 31-75).&#x0D; Most incisional hernias were midline xiphoid-pubic incision and supraumbilical, with several subcostals (2 right and 1 left) hernias.At the time of repair, most incisional hernias were symptomatic and evident on physical exam. In four cases, the hernia sac was incarcerated at the presentation time.&#x0D; Conclusion: The Rives-Stoppa technique has excellent long-term results and low morbidity in patients with large primary or recurrent incisional hernias. It is the gold standard for most surgeons.&#x0D; Keywords: Incisional Hernia, mesh, polypropylene, abdominal wall surgery, rectus muscle

A morbidly obese patient with large incisional hernia managed with posterior compartment separation sub-lay mesh placement

Most of the incisional hernias are diagnosed in first 3 years after the major abdominal surgery but some may take 9-10 years before the presentation after surgery. Risk factors to develop incisional hernia includes patient factors; advanced age, hypertension, diabetes, obesity, anemia, smoking, chronic obstructive pulmonary disease (COPD), immunosuppression, previous coronary intervention, renal disease requiring dialysis, recent weight loss and malnutrition. Surgery related risk factors includes intraoperative complication, suture technique, surgical site infections, fascial dehiscence and other postoperative complications. We are presenting of large incisional hernia, which have managed with posterior compartment separation. Large incisional ventral hernias following abdominal surgeries can pose significant challenges in management and quality of life for both patients. The Rives-Stoppa repair technique provides authentic and essential solution for management of large complex ventral hernias with reducing the risk of recurrence and providing long-term support to the abdominal wall.

Strategies for closing the posterior rectus sheath during enhanced view totally extraperitoneal Rives-Stoppa repair.

The popularity of endolaparoscopic extraperitoneal repairs has been on the rise due to advantages such as sublay mesh placement and early return to daily activities. However, the procedure requires overcoming a learning curve, and with increased adoption, new complications have emerged. One significant complication is the rupture of the posterior rectus sheath (PRS). In this article, we present our modifications of the technique to reduce tension during PRS closure. The study included 105 patients who underwent endolaparoscopic extraperitoneal repairs for ventral hernias using two different techniques. Group A (n = 68) underwent the original technique, whereas Group B (n = 37) underwent the modified technique. The modifications in Group B included preserving the peritoneal bridge between the two PRS and the hernia sac, conducting a complete dissection of the space of Bogros and adopting a transverse or oblique closure of PRS along the lines of least tension. To assess the efficacy of these modifications in preventing PRS rupture, we compared the results of both groups. Our findings indicate that following all the technical steps of the modified technique resulted in a reduced need for transversus abdominis release for PRS closure and a lower incidence of PRS rupture in the postoperative period. However, to further validate the effectiveness of these modifications, a larger follow-up period and a bigger sample size are required. The adoption of the modified technique can help achieve a tension-free PRS closure.

WTP5.3 Setting up a Complex Abdominal Wall Reconstruction Unit: Our first 12 months’ experience in a District General Hospital

Abstract Aims Incisional hernias are distressing post-operative complications which develop in 25% of surgical incisions. We present our initial experience of setting up a Complex Abdominal Wall Reconstruction (CAWR) unit in line with international guidelines and Get It Right First Time (GIRFT) model of care. Methods A bespoke CAWR Multidisciplinary Team was established in our trust in January 2022, comprising 2 colorectal surgeons, 2 bariatric surgeons and anaesthetists (who performed the preoperative Botox injections and optimized high-risk patients). The unit had support from radiologists, the weight management service, and the orthotics department. We had approval from our governance, drugs and therapeutics team. Pathways for risk stratification, risk modification with pre-optimisation, standardised surgical techniques and post-operative care were created. Results Between January and December 2022, 8 MDT meetings held and 52 patients were discussed. The average BMI was 34 (22-50.5) All patients underwent a preoperative CT scan to delineate the anatomy of the hernia. The median size of the defect was 6 cm (range 3 to 22 cm). Open Rives-Stoppa repair was performed in 19 patients, with transversus abdominal muscle release in 6 and 3 patients had laparoscopic repair. One recurrence and 2 superficial surgical site infections were noted. 38.4% patients had BOTOX, 40.3% advised preoperative weight loss and 5.7% for bariatric surgery before hernia repair. A high-risk anaesthetic opinion was obtained in for 7.6% and 17% were deemed unfit. Conclusions Our initial experience and data highlight the feasibility of delivery of CAWR service at a non-tertiary unit in line with GIRFT principles. The initial follow-up indicates improved patient outcomes and experience.

P-024 INITIAL EXPERIENCE OF EXTENDED TEP REPAIR FOR VENTRAL AND INCISIONAL HERNIAS IN OUR HOSPITAL

Abstract Aim The purpose of this study was to investigate the treatment outcomes and feasibilities of the enhanced view totally extraperitoneal (eTEP) repair for ventral and incisional hernias in our hospital. Material &amp; Methods We retrospectively reviewed the medical records of patients who underwent eTEP repair for ventral and incisional hernias in our hospital from October 2018 to April 2022. Demographic information, preoperative evaluations, intraoperative variables, postoperative outcomes were collected and analyzed. The surgical techniques were followed the article published by Daes et al in 2021. Results Thirty-two patients underwent eTEP repair during the study period. These patients had mean age of 60.8 years, mean BMI 27.1 kg/m2, and median ASA score 2. Twenty-six had incisional hernias (4 were recurrent incisional hernias) and six were primary ventral hernias. Nineteen had hernias in M3 location, mean defect width and length size were 6.00 and 7.47 cm. Sixteen had diastasis rectis and eight had incarcerations at the time of surgery. Twenty-eight underwent eTEP Rives-Stoppa (RS) repair (23 the conventional laparoscopic ports, 2 reduced ports, 1 single port, and 1 robotic). Four underwent eTEP transversus abdominis release (TAR) using the conventional laparoscopic ports. Mean operation time was 199 (±48.5) minutes and mean estimate blood loss volume was 25.8 (±27.2) ml. The common postoperative complications were seroma and voiding difficulty and mean hospital stay length was 8.25 (±4.45) days. There were two recurrences within follow-up period. Conclusion Our initial experience of eTEP repair for ventral and incisional hernias showed favorable treatment outcomes and feasibilities.

V-002 Robotic suprapubic eTEP retrorectus repair for incisional hernia

Abstract Aim A retrorectus mesh position is often considered the most suitable for the repair of a midline incisional hernia. The minimal invasive extraperitoneal approach is gaining popularity. Material &amp; Methods A 56-year-old female patient, who had a laparoscopic deroofing of a bile cyst in her history, presented with an incisional midline hernia (EHS M2-M3, width 6.6 cm). Preoperative optimization via dietary instructions reduced her BMI from 40 kg/m2 to a BMI of 35 kg/m2. Results A robotic extraperitoneal approach via suprapubic docking was performed. The patient is positioned supine and flexed for 15° at the level of the spina iliaca. An intraperitoneal trocar is placed to explore the abdomen for adhesions. Three trocars are placed in the suprapubic position in the extraperitoneal plane whereafter the robot is docked. A dissection in the cranial direction is performed in the retrorectus plane by incising both posterior rectus fascia in a symmetric way. A preperitoneal plane behind the linea alba is created. At the level of the hernia defect the hernia sac is opened, and adhesions are freed. Once the retrorectus space is dissected up to the xyphoid, the linea alba is reconstructed with a barbed suture size 0. A self-fixating mesh is placed in the retrorectus position. The posterior layer of the peritoneum is closed. The postoperative course was uneventful. Conclusions We present an extraperitoneal minimal invasive approach to the retrorectus plane allowing for an adequate retrorectus dissection and mesh placement like in a classical Rives-Stoppa repair.

Robotic transversus abdominis release: A paradigm shift in complex abdominal wall surgery?

Abdominal wall reconstruction techniques have evolved significantly over the last fifty years and continue to do so at an increasing pace. Beginning with open incisional hernia repair with bilateral rectus myofascial release, multiple techniques to offset tension at the midline by exploring options of layered myofascial release have been described. This article reviews the history, technique, advancements, and future of myofascial release in abdominal wall reconstruction leading from the open Rives-Stoppa repair to the robotic-assisted iteration of the transversus abdominis release.

P-135 FIRST EXPERIENCE WITH A NEW CLOSED INCISION NEGATIVE PRESSURE WOUND THERAPY, PREVENA™, IN ABDOMINAL WALL RECONSTRUCTION PATIENTS

Abstract Aim Surgical site infection (SSI) contributes a significant proportion of post operative morbidity in patients undergoing abdominal wall reconstruction (AWR). Prevena™ closed incision negative pressure wound therapy (ciNPT) has been demonstrated to reduce SSI rates in the elective and emergency laparotomy setting. However, there is no evidence for Prevena™ use in AWR patients. The aim of this study was to assess the safety and feasibility of Prevena™ in AWR patients. Materials and Method Patients undergoing AWR at a single trust were selected at random to receive Prevena™. This was applied to the incision under sterile conditions, a continuous pressure of -125mmHg was applied for 7 days. The primary outcome measure was SSI, with secondary outcomes of 90 day mortality, complications and length of stay. Results 10 patients received ciNPT in the study period, 8 female 2 male, mean BMI was 34.5. All patients had a Rives-Stoppa repair, with 2 patients also requiring bilateral transversus abdominal release (TAR). A vertical panniculectomy with umboplasty was used in 7 cases, fleur-de-lys panniculectomy with umboplasty in 2 cases, and a single case approached via transverse panniculectomy. There were no deaths within 90 days, median length of stay was 4 days. There was a single SSI managed with oral antibiotics, not requiring admission. Conclusion Prevena™ has been shown to reduce SSI rates in other patient cohorts and this small series demonstrates it is feasible and safe to use in the AWR setting. Larger studies are required to demonstrate SSI rate reduction in AWR patients.

OC-031 INCIDENCE AND RISK FACTORS FOR RECURRENCE OF RIVES-STOPPA REPAIR FOR INCISIONAL HERNIAS. TWENTY-YEAR RETROSPECTIVE ANALYSIS OF LONG-TERM OUTCOMES OF DIFFERENT MESH REPAIRS

Abstract Objective the aim of this study was to determine the long-term recurrence and complication rates following Rives-Stoppa repair of midline incisional hernias with different types of synthetic materials. Patients and Methods medical files of 1628 patients with midline incisional hernias who underwent abdominal wall reconstruction using Rives-Stoppa repair between January 1999 and December 2019 were reviewed. All patients followed up after 1 month, 6 months, and 1year later and after that yearly. Results until 2007, 674 patients were operated on with available meshes for that time (mosquito net – 135, polyester mesh – 322, and polypropylene mesh – 217). After 2007, polypropylene meshes were used in 1054 patients (heavyweight in 428 patients and lightweight meshes in 626). The global recurrence rate after a mean follow-up of 96.5 months in the first group of patients was 13.3% and in the second group was 7.13% (mean follow-up of 108.4 months). The infection rate was 16.8% versus 9.2% with an increased incidence at 30 days (84 vs 62 patients). The hematoma rate was equally distributed. Seroma formation was almost 2.5-fold increased in the first group of patients (21.3% vs 8.7%). Increased rate of seroma formation were associated with mosquito net (OR = 1.7; 95% CI = 0.5–1.3; p=o.o2), heavyweight type type (OR = 0.9; 95 CI = 0.07–0.4; p=o.o31). Infection was associated with the usage of mosquito net, heavyweight type, and polyester mesh. Conclusions the lightweight mesh offers a safe method for abdominal wall reconstruction.

V-024 LAPAROSCOPIC ENHANCED-VIEW TOTALLY EXTRAPERITONEAL RIVES-STOPPA REPAIR (E-TEP RS). FIRST EXPERIENCE AT HOSPITAL UNIVERSITARIO DE CANARIAS

Abstract We present the case of a 55-years-old female with a personal history: high blood pressure, dyslipidemia, without previous abdominal surgeries. Height: 1,65 m; Weight: 62 Kg. BMI: 22,7. Clinical and ultrasound diagnosis of a painful and partially reducible ventral hernia M2 W1 (EHS Classification). It is programmed for hernia correction using the Laparoscopic Enhanced-View Totally Extraperitoneal Rives-Stoppa Repair (e-TEP RS) technique adapted to the hernia defect. Access is made to the left retrorectal space on the left flank, medial to the semilunar line but lateral to the epigastric vessels; dissection of the retrorectal space with a disector balloon on a 5 cm perimeter around the hernia defect; pneumoperitoneum; cross-over manoeuvre connecting the two retrorectal spaces with the medial preperitoneal space; dissection and reduction of the hernia sac; closure of the hernia defect with bearded reabsorbable suture. Implantation of polyvinylidene fluoride (PVDF) macroporous mesh in retrorectal space without using any type of fixation. A retromuscular closed-suction drain is then placed and the place is then desuflatted. The patient is discharged at 12 hours postoperative with in situ drainage, wich was removed in consultation 48 horas after surgery due to null debit. We present the first published case, in our latitude, of a e-TEP RS adapted to the hernia defect. It is a challenging but safe and effective technique as well as practically painless postoperative technique.

The Use of Inlay Bridge of the Posterior Fascia as Adjuvants to a Modified Rives-Stoppa Repair for Difficult Abdominal Wall Hernias.

Major abdominal wall defects remain a highly morbid complication. Occasionally a fascial defect is encountered, that despite all surgical efforts, is unable to completely approximate at the midline. Here we describe our method and outcomes of using a bridging mesh when the posterior fascia was unable to be approximated during the repair of large postoperative ventral hernias using the modified Rives-Stoppa technique. A retrospective review was conducted looking at all the open abdominal wall hernia repairs between 2014 and 2020. The cohort of patients who had a bridge placed in addition to the traditional open modified Rives-Stoppa repair were used for this study. Nineteen patients had a mesh inlay bridge placed in addition to a modified Rives-Stoppa repair with a sublay (retrorectus) Ultrapro mesh. For the inlay mesh 13 Symbotex composite meshes were placed and 6 Vicryl meshes used. The average surface area of the defect was 358.1cm^2. The average length of hospitalization was 8.8days with a range of 3-24days. During the immediate postoperative course there were 6 minor complications. During the follow-up period there were 2 recurrences. The use of inlay mesh bridge as an adjuvant to a modified Rives-Stoppa repair with a sublay ultrapro mesh is an effective technique for difficult abdominal wall repairs where the posterior fascia is unable to be approximated without tension.

ETEP inferior access with tailored retromuscular dissection for small to mid-sized umbilical hernia repair with or without inguinal hernia: early experience.

The minimally invasive surgical repair of combined inguinal and ventral hernias often requires shifting from one approach or plane to another. The traditional enhanced-view totally extraperitoneal Rives-Stoppa repair consists of a large retro muscular dissection that is unjustified for small ventral hernias. Here we describe a modification to the minimally invasive Rives-Stoppa repair using a limited retro muscular dissection based on the ventral defect size for small/medium-sized hernias, with or without combined inguinal hernias. From a single surgical team, a retrospective study was performed over a 1-year period. Demographics, hernia characteristics, surgical techniques, intraoperative/postoperative complications, and outcomes were all analyzed and reported. We also included detailed surgical steps, landmarks, pitfalls, and personal tips for this technique. Twenty-four patients underwent a laparoscopic limited retromuscular dissection ventral hernia repair utilizing the eTEP access technique. Eighteen were primary umbilical hernias and six postoperative incisional hernias, and nine were combined ventral and inguinal hernia repairs. Eight of the primary umbilical hernias were EHS classified as medium size, 11 small, and for the incisional hernias, three were classified as M3W1 and two as M3W2. One procedure was converted to TAPP. There were no intraoperative complications. The mean length of stay was 1.25days (range 1-3). There was one postoperative retromuscular hematoma and no recurrence during the follow-up period. eTEP with limited dissection offers a good and safe solution for small to medium size hernias; it provides an efficient solution when an inguinal hernia is to be addressed as well.
