Shouldice versus Lichtenstein inguinal hernia repair: A meta-analysis of randomized controlled trials.

The Lichtenstein technique is the standard treatment for adult open inguinal hernia repair. Among the non-mesh repair techniques, Shouldice has shown the best results and is comparable to mesh repairs in selected cases. Due to the risk of chronic groin pain associated with the Lichtenstein technique, Shouldice has increased in popularity, and some surgeons have adopted it as a viable first-line option. MEDLINE, Cochrane, Central Register of Clinical Trials, and EMBASE for randomized controlled trials (RCT) published until February 2024. Risk ratios (RRs) with 95% confidence intervals (CIs) were pooled using a random-effects model. Heterogeneity was assessed using the Cochran Q test and I2 statistics with p-values <0.10 and I2 > 25% considered significant. Statistical analysis was performed using R Software, version 4.1.2. Fourteen RCTs comprising 2784 patients were included, of whom 1379 (47.5%) were submitted to the Shouldice hernia repair and 1513 (52.5%) to the Lichtenstein technique. Shouldice was associated with a significant increase in the recurrence rate (4.2% vs. 0.9%; RR 3.68; 95% CI 2.05-6.60; p<0.001; I2=0%) compared with Lichtenstein. The number needed to treat (NNT) to prevent one Shouldice recurrence was 30.3. There were no significant differences between groups in chronic pain, urinary retention, bladder injury, testicular atrophy, wound infection, hematoma-seroma, or hypesthesia. The Lichtenstein technique was associated with reduced recurrence rates compared with Shouldice in patients undergoing inguinal hernia repair. However, the overall recurrence rate with the Shouldice technique was still low (4.2%), suggesting that it may be a viable option in selected patients.

Mesh vs. non-mesh repair of type I hiatal hernias: a propensity-score matching analysis of 6533 patients from the Herniamed registry

IntroductionSurgical treatment of type I hiatal sliding hernias aims to control the gastroesophageal reflux symptoms and prevention of hernia recurrence. Usually, a cruroplasty is performed to narrow the hiatal orifice. Here, it remains controversial if a mesh reinforcement of the cruroplasty should be performed, since benefits as well as mesh-associated complications have been described.MethodsWe performed a propensity-score matching analysis with data derived from the Herniamed registry comparing patients undergoing laparoscopic type I hiatal hernia repair with and without synthetic mesh. We analyzed perioperative, intraoperative, and postoperative data including data derived from the 1-year follow-up in the registry.Results6.533 patients with an axial, type I hiatal hernia and gastroesophageal reflux are included in this analysis. Mesh augmentation of the hiatoplasty was performed in n = 1.252/6.533 (19.2%) of patients. The defect size in the subgroup of patients with mesh augmentation was with mean 16.3 cm2 [14.5; 18.2] significantly larger as in the subgroups without mesh augmentation with 10.8 cm2 [8.7; 12.9]; (p < 0.001). In patients with mesh hiatoplasty n = 479 (38.3%) Nissen and n = 773 (61.7%) Toupet fundoplications are performed. 1.207 matched pairs could be analyzed. The mean defect size after matching was with 15.9 cm2 comparable in both groups. A significant association was seen regarding recurrence (4.72% mesh vs. 7.29% non-mesh hiatoplasty, p = 0.012). The same relation can be seen for pain on exertion (8.78% vs 12.10%; p = 0.014) and pain requiring treatment (6.13% vs 9.11%; p = 0.010). All other outcome parameter showed no significant correlation.ConclusionsOur data demonstrate that mesh-reinforced laparoscopic type I hiatal hernia repair in larger defects is associated with significantly lower rates for recurrence, pain on exertion and pain requiring treatment.

Higher rate of chronic pain in young men after open mesh vs nonmesh repair of elective primary unilateral indirect inguinal hernia: A nationwide questionnaire study

PurposeYoung age is a risk factor for chronic pain after inguinal hernia repair, but the role of the mesh in young patients is uncertain. The aim of this study was to assess chronic pain after open mesh versus non-mesh repair of indirect inguinal hernia in young men. Materials and methodsValidated questionnaires were sent to men aged 18–29 years at the time of an elective primary unilateral open repair of an indirect inguinal hernia between 1998 and 2015. Patients were identified in the Danish Hernia Database. Non-mesh repairs were matched 1:3 with mesh repairs (Lichtenstein) on age and follow-up time. The primary outcome was the proportion of patients with chronic pain evaluated with the Activity assessment scale. Secondary outcomes included other pain measures and sexual impairment. ResultsIn total, 661 patients were included in this study (77% mesh and 23% non-mesh) with a median follow-up of 14.8 years (range 2.3–20.0) in the mesh group and 15.9 years (range 3.6–20.0) in the non-mesh group. For the primary outcome, 12% of patients in the mesh group compared with 6% in the non-mesh group had chronic pain (p=0.03). Patients in the mesh group had higher odds of chronic pain in adjusted analysis (OR=2.30 [95% confidence interval=1.11–4.77]). More patients in the mesh group had pain during sexual activity (p=0.01), but there were no differences for most of the remaining secondary outcomes. ConclusionYoung men had a higher rate of chronic pain after open mesh compared with non-mesh repair for indirect inguinal hernia, but results should be interpreted with caution.

Non-mesh inguinal hernia repair with early resumption of peritoneal dialysis in patients on continuous ambulatory peritoneal dialysis.

Inguinal hernia is a common complication of peritoneal dialysis (PD). Although tension-free mesh repair is a leading option for inguinal hernia repair, concerns over serious mesh-related complications may indicate a role for non-mesh inguinal hernia repair. In addition, there is no consensus on the perioperative dialysis regimen. Early resumption of PD may avoid the additional risks associated with hemodialysis. We report on the outcomes of non-mesh inguinal hernia repair in patients on continuous ambulatory PD (CAPD) and provide a perioperative dialysis protocol that aims to guide early resumption of PD. Between May 2019 and September 2023, thirty CAPD patients with 43 inguinal hernias who underwent non-mesh inguinal hernia repair were retrospectively analyzed. Data on the patient characteristics, perioperative dialysis regimen, perioperative features, complications, and hernia recurrence were collected and assessed. Thirty patients with a total of 43 inguinal hernia repairs were included in this study. The median age was 53years. 23 patients were male and 7 were female. Non-mesh inguinal repair was performed for all patients. PD was resumed at a median of 2days after the surgery. Five patients received interim hemodialysis. There were no postoperative surgical or uremic complications and no recurrence after a median follow-up of 31.5months. Our study demonstrates the effectiveness and safety of non-mesh repair with early resumption of PD in patients on CAPD. Interim HD is unnecessary in selected patients. Choosing the optimal perioperative dialysis regimen is essential to managing inguinal hernias in CAPD patients.

Open preperitoneal inguinal hernia repair has superior 1-year patient-reported outcomes compared to Shouldice non-mesh repair.

The Shouldice method for inguinal hernia repair remains the gold standard for prosthesis-free repairs. Nonetheless, international guidelines have favored posterior mesh reinforcement as the standard of care for inguinal hernia repair due to lower risk of recurrence and chronic pain, avoidance of general anesthesia, and favorable biomechanical properties. Recent publications have shown the benefits of an open approach to posterior repairs. Herein, we use the Abdominal Core Health Quality Collaborative (ACHQC) registry to compare patient-reported outcomes after a Shouldice no-mesh repair versus open preperitoneal (OPP) mesh repair. We performed a propensity score matched analysis to compare patient-reported quality of life (QoL) and peri/postoperative outcomes after a Shouldice repair versus OPP. Data from 2012 to 2022 were obtained from the ACHQC, and 1:1 optimal matching was performed. EuraHS scores were used to estimate QoL, and further analysis on the EuraHS domains of pain, aesthetics, and activity restriction were performed between the two cohorts. Matching resulted in 257 participants in each, Shouldice and OPP cohorts. OPP was associated with a better QoL score compared to Shouldice at 30days after surgery (Median (IQR) 7.75 (2.0-17.0) vs 13.0 (4.0-26.1); OR 0.559 [0.37, 0.84]; p = 0.003). This difference persisted at 6 months and 1 year postoperatively (OR 0.447 [0.26, 0.75] and 0.492 [0.26, 0.93], respectively). We did not observe any significant differences in hernia recurrence risk at 1-year, or rates of 30-day SSOs/SSIs, postoperative bleeding, peripheral nerve injury, DVTs, or UTIs. Our data suggest that OPP is associated with significantly better patient-reported QoL, in the first month after surgery and up to 1 year postoperatively, especially with respect to lesser pain, when compared to the Shouldice repair. In specialized inguinal hernia practices, open posterior mesh repairs may lead to better outcomes than non-mesh repairs. We encourage more training in both repairs to facilitate larger prospective studies and evaluation of the generalizability of these results to all surgeons performing IHR.

OGBN O07 Factors in recurrence following 862 giant paraesophageal hernia repairs

Abstract Background Repair of giant paraesophageal hernia (PEH) is associated with a considerable hernia recurrence rate by objective measures. This study evaluated trends in outcomes of laparoscopic non-mesh repair of giant PEH over 30 years, and factors associated with anatomical recurrence. Methods Data was extracted from a single-surgeon prospective database of laparoscopic repair of giant PEH from 1991-2021. Upper endoscopy was performed within 12 months postoperatively and selectively thereafter. Any supra-diaphragmatic stomach was defined as anatomical recurrence. Cases were chronologically divided into tertiles with trends in casemix, operative factors and outcomes evaluated. Patient and hernia characteristics, and technical operative factors, including “composite repair” (360-degree fundoplication with esophagopexy and cardiopexy to right crus), were evaluated with univariate and multivariate analysis. Results 862 repairs met selection criteria. Mean age 69.3years, majority(65.8%) female and hernia type III(87.4%) with median hernia size 66%. There was an increasing proportion of “composite repair” after the first decade(Group1, 2.7%;Group2, 81.9%;Group3, 100%;p&amp;lt;0.001).There were less anatomical hernia recurrence(Group1, 36.6%;Group2, 22.9%;Group3, 22.7%;p&amp;lt;0.001) over time. The overall anatomical recurrence rate was 27.3% with median followup 33months(IQR 16, 68). There were 10(1.2%) Clavien-Dindo grade ≥III complications including two perioperative deaths(0.2%). Multivariate analysis identified age&amp;lt;70years, presence of Barrett’s, absence of “composite repair”, and hiatus closure under tension as independent factors associated with recurrence(HR1.27,95%CI0.88-1.82,p=0.01;HR1.58,95%CI1.12-2.23,p=0.009;HR1.72,95%CI1.2-2.44,p=0.002;HR2.05,95%CI1.33-3.17,p=0.001,respectively). Conclusions Hernia recurrence rates decreased with increasing case volume. This coincided with the increasing adoption of “composite repair”, supporting the possible improvement in recurrence rates with this approach. Repair was associated with substantial anatomical recurrence associated with patient and technique factors. Patient factors included age &amp;lt;70 years, Barrett’s esophagus, and hiatus tension. “Composite repair” was associated with lower recurrence rate.

A western trauma association multicenter comparison of mesh versus non-mesh repair of blunt traumatic abdominal wall hernias

BackgroundBlunt traumatic abdominal wall hernias (TAWH) occur in <1 % of trauma patients. Optimal repair techniques, such as mesh reinforcement, have not been studied in detail. We hypothesize that mesh use will be associated with increased surgical site infections (SSI) and not improve hernia recurrence. Materials and methodsA secondary analysis of the Western Trauma Association blunt TAWH multicenter study was performed. Patients who underwent TAWH repair during initial hospitalization (1/2012–12/2018) were included. Mesh repair patients were compared to primary repair patients (non-mesh). A logistic regression was conducted to assess risk factors for SSI. Results157 patients underwent TAWH repair during index hospitalization with 51 (32.5 %) having mesh repair: 24 (45.3 %) synthetic and 29 (54.7 %) biologic. Mesh patients were more commonly smokers (43.1 % vs. 22.9 %, p = 0.016) and had a larger defect size (10 vs. 6 cm, p = 0.003). Mesh patients had a higher rate of SSI (25.5 % vs. 9.5 %, p = 0.016) compared to non-mesh patients, but a similar rate of recurrence (13.7 % vs. 10.5%, p = 0.742), hospital length of stay (LOS), and mortality. Mesh use (OR 3.66) and higher ISS (OR 1.06) were significant risk factors for SSI in a multivariable model. ConclusionMesh was used more frequently in flank TAWH and those with a larger defect size. Mesh use was associated with a higher incidence and risk of SSI but did not reduce the risk of hernia recurrence. When repairing TAWH mesh should be employed judiciously, and prospective randomized studies are needed to identify clear indications for mesh use in TAWH.

Mesh repair versus non-mesh repair for incarcerated and strangulated groin hernia: an updated systematic review and meta-analysis.

Mesh repair in incarcerated or strangulated groin hernia is controversial, especially when bowel resection is required. We aimed to perform a meta-analysis comparing mesh and non-mesh repair in patients undergoing emergency groin hernia repair. We performed a literature search of databases to identify studies comparing mesh and primary suture repair of patients with incarcerated or strangulated inguinal or femoral hernias who underwent emergency surgery. Postoperative outcomes were assessed by pooled analysis and meta-analysis. Statistical analysis was performed using RevMan 5.4. Heterogeneity was assessed with I2 statistics. 1095 studies were screened and 101 were thoroughly reviewed. Twenty observational studies and four randomized controlled trials comprising 12,402 patients were included. We found that mesh-based repair had reduced recurrence (OR 0.36; 95% CI 0.19, 0.67; P = 0.001; I2 = 35%), length of hospital stay (OR -1.02; 95% CI -1.87, -0.17; P = 0.02; I2 = 94%) and operative time (OR -9.21; 95% CI -16.82, -1.61; P = 0.02; I2 = 95%) without increasing surgical site infection, mortality or postoperative complications such as seroma, chronic, ileus or urinary retention. In the subgroup analysis of patients that underwent bowel resection, we found that mesh repair was associated with an increased risk of surgical site infection (OR 1.74; 95% CI 1.04, 2.91; P = 0.04; I2 = 9%). Mesh repair for incarcerated and strangulated groin hernias reduces recurrence without an increase in postoperative complications and should be considered in clean cases. However, in the setting of bowel resection, mesh repair might increase the incidence of surgical site infection.

Trends in outcomes of 862 giant hiatus hernia repairs over 30 years

PurposeLaparoscopic giant hiatus hernia repair is technically difficult with ongoing debate regarding the most effective surgical technique. Repair of small hernia has been well described but data for giant hernia is variable. This study evaluated trends in outcomes of laparoscopic non-mesh repair of giant paraesophageal hernia (PEH) over 30 years.MethodsRetrospective analysis of a single-surgeon prospective database. Laparoscopic non-mesh repairs for giant PEH between 1991 and 2021 included. Three-hundred-sixty-degree fundoplication was performed routinely, evolving into “composite repair” (esophagopexy and cardiopexy to the right crus). Cases were chronologically divided into tertiles based on operation date (Group 1, 1991–2002; Group 2, 2003–2012; Group 3, 2012–2021) with trends in casemix, operative factors and outcomes evaluated. Hernia recurrence was plotted using weighted moving average and cumulative sum (CUSUM) analysis.Results862 giant PEH repairs met selection criteria. There was an increasing proportion of “composite repair” after the first decade (Group 1, 2.7%; Group 2, 81.9%; Group 3, 100%; p < 0.001). There were less anatomical hernia recurrence (Group 1, 36.6%; Group 2, 22.9%; Group 3, 22.7%; p < 0.001) and symptomatic recurrence (Group 1, 34.2%; Group 2, 21.9%; Group 3, 7%; p < 0.001) over time. The incidence of anatomical recurrence declined over time, decreasing from 30.8% and plateauing below 17.6% near the study’s end. Median followup (months) in the first decade was higher but followup between the latter two decades comparable (Group 1, 49 [IQR 20, 81]; Group 2, 30 [IQR 15, 65]; Group 3, 24 [14, 56]; p < 0.001). There were 10 (1.2%) Clavien–Dindo grade ≥ III complications including two perioperative deaths (0.2%).ConclusionHernia recurrence rates decreased with increasing case volume. This coincided with the increasing adoption of “composite repair”, supporting the possible improvement in recurrence rates with this approach.

SP9.12 The Global Practice of Inguinal Hernia Repair Study (GLACIER): A survey of 1014 hernia surgeons

Abstract Introduction There are many variations in practices and preferences for inguinal hernia repair among surgeons globally. The purpose of the Global Practice of Inguinal Hernia Repair Study (GLACIER) was to capture these variations related to open, laparoscopic, and robotic inguinal hernia repair. Method A questionnaire-based survey on Survey Monkey® was created, and the link was shared freely on various social media platforms, personal email network of authors and email to members of the endorsed organisations, which include British Hernia Society (BHS), The Upper Gastrointestinal Surgical Society (TUGSS), and Abdominal Core Health Quality Collaborative (ACHQC). Results A total of 1014 surgeons from 81 countries completed the survey. Open and laparoscopic approaches were equally preferred (43% and 47% respectively). Transabdominal pre-peritoneal repair (TAPP) is the favoured minimally invasive approach. Bilateral and recurrent hernia following previous open repair were the most common indications for minimally invasive approach. Repair with a mesh was preferred by 98% of the surgeons and synthetic monofilament light weight mesh with large pores was the most common choice. Lichtenstein repair was the most favoured open mesh repair technique (90%), while Shouldice repair was the favoured non-mesh repair technique. The risk of chronic groin pain was quoted as 5% after open repair and, 1% after minimally invasive repair. Only 10% of surgeons preferred open repair with local anaesthesia. Conclusion This survey identified similarities and variations in practice globally along with some discrepancies in inguinal hernia repair compared to best practice guidelines. It also identifies several key areas where more focus future research is required.

EFFECTIVENESS OF SYNTHETIC IMPLANTS FOR GENITAL PROLAPSE SURGERY

The aim of the study is to evaluate the effectiveness of synthetic implants for genital prolapse surgery in women of different age groups.&#x0D; Materials and Methods. 139 patients underwent genital prolapse surgery, vaginal approach, with synthetic mesh and biologic grafts. For the anterior, posterior and complete reconstruction of the vaginal walls, two mesh implants were used: Pelvix (Lintex, Russia) and Prolift (Ethicon Women´s Health and Urology, Johnson and Johnson Company, USA). The size of mesh implant was adapted to each particular case.&#x0D; Results. The most common intraoperative complication was intraoperative blood loss. During pelvic floor reconstruction with mesh implants, it was 1.8 times and 1.5 times higher in reproductive age and perimenopause respectively, compared with grafts. In postmenopause, there was a tendency to greater blood loss in surgeries with biological grafts. In reproductive age, the frequency of early postoperative complications was the same for mesh and non-mesh repair. In perimenopause, complications were three times more often for mesh repair, and in postmenopause, complications were observed in every third examined patient, regardless of the repair used. Late postoperative complications (pelvic pain and dyspareunia) occurred more often for biological graft: in reproductive age – twice, in perimenopause – 1.5 times, and in postmenopause – 5 times as frequently as for mesh.&#x0D; Conclusion. Prolapse surgery with synthetic implants is effective, safe and justified in terms of pathogenesis.

An international survey of 1014 hernia surgeons: outcome of GLACIER (global practice of inguinal hernia repair) study.

The practice of inguinal hernia repair varies internationally. The global practice of inguinal hernia repair study (GLACIER) aimed to capture these variations in open, laparoscopic, and robotic inguinal hernia repair. A questionnaire-based survey was created on a web-based platform, and the link was shared on various social media platforms, personal e-mail network of authors, and e-mails to members of the endorsed organisations, which include British Hernia Society (BHS), The Upper Gastrointestinal Surgical Society (TUGSS), and Abdominal Core Health Quality Collaborative (ACHQC). A total of 1014 surgeons from 81 countries completed the survey. Open and laparoscopic approaches were preferred by 43% and 47% of participants, respectively. Transabdominal pre-peritoneal repair (TAPP) was the favoured minimally invasive approach. Bilateral and recurrent hernia following previous open repair were the most common indications for a minimally invasive procedure. Ninety-eight percent of the surgeons preferred repair with a mesh, and synthetic monofilament lightweight mesh with large pores was the most common choice. Lichtenstein repair was the most favoured open mesh repair technique (90%), while Shouldice repair was the favoured non-mesh repair technique. The risk of chronic groin pain was quoted as 5% after open repair and 1% after minimally invasive repair. Only 10% of surgeons preferred to perform an open repair using local anaesthesia. This survey identified similarities and variations in practice internationally and some discrepancies in inguinal hernia repair compared to best practice guidelines, such as low rates of repair using local anaesthesia and the use of lightweight mesh for minimally invasive repair. It also identifies several key areas for future research, such as incidence, risk factors, and management of chronic groin pain after hernia surgery and the clinical and cost-effectiveness of robotic hernia surgery.

Management and outcomes of obturator hernias: a systematic review and meta-analysis.

Obturator Hernia (OH) is a rare type of abdominal wall hernia. It usually occurs in elderly women with late symptomatic presentation, increasing mortality rates. Surgery is the standard of care for OH, and laparotomy with simple suture closure of the defect is commonly used. Given the rarity of this disease, large studies are lacking, and data to drive management are still limited. This systematic review and meta-analysis aimed to describe current surgical options for OHs, with a focus on comparing the effectiveness and safety of mesh use with primary repair. PubMed, EMBASE, and Cochrane were searched for studies comparing mesh and non-mesh repair for OH. Postoperative outcomes were assessed by pooled analysis and meta-analysis. Statistical analysis was performed using RevMan 5.4. One thousand seven hundred and sixty studies were screened and sixty-seven were thoroughly reviewed. We included 13 observational studies with 351 patients surgically treated for OH with mesh or non-mesh repair. One hundred and twenty (34.2%) patients underwent mesh repair and two hundred and thirty-one (65.81%) underwent non-mesh repair. A total of 145 (41.3%) underwent bowel resection, with the majority having a non-mesh repair performed. Hernia recurrence was significantly higher in patients who underwent hernia repair without mesh (RR 0.31; 95% CI 0.11-0.94; p = 0.04). There were no differences in mortality (RR 0.64; 95% CI 0.25-1.62; p = 0.34; I2 = 0%) or complication rates (RR 0.59; 95% CI 0.28-1.25; p = 0.17; I2 = 50%) between both groups. Mesh repair in OH was associated with lower recurrence rates without an increase in postoperative complications. While mesh in clean cases is more likely to offer benefits, an overall recommendation regarding its use in OH repair cannot be made due to potential bias across studies. Given that many OH patients are frail and present emergently, the decision to use mesh is complex and should consider the patient's clinical status, comorbidities, and degree of intraoperative contamination.

Low incidence of recurrence and chronic pain after groin hernia repair in adolescents: a systematic review and meta-analysis

PurposeThe best operative management of groin hernia in adolescents is uncertain. The aim of this systematic review was to assess recurrence and chronic pain after mesh versus non-mesh repair for groin hernia in adolescents.MethodsA systematic search was done in PubMed, EMBASE, and Cochrane CENTRAL in May 2022 for studies reporting postoperative chronic pain (≥6 months) or recurrence after groin hernia repair in adolescents aged 10–17 years. We included randomized controlled trials and observational studies on primary unilateral or bilateral groin hernia repair. Risk of bias was assessed with the Cochrane risk-of-bias tool and Newcastle-Ottawa Scale. Meta-analysis of the incidence of recurrence was conducted. This review is reported according to PRISMA guideline.ResultsA total of 21 studies including 3,816 adolescents with groin hernias were included comprising two randomized controlled trials, six prospective, and 13 retrospective cohort studies. For non-mesh repairs, the weighted mean incidence proportion of recurrence was 1.6% (95% CI 0.6–2.5) after 2,167 open repairs and 1.9% (95% CI 1.1–2.8) after 1,033 laparoscopic repairs. For mesh repairs, it was 0.6% (95% CI 0.0–1.4) after 406 open repairs while there were no recurrences after 347 laparoscopic repairs (95% CI 0.0–0.6). Across all surgical techniques, the rate of chronic pain after 1,153 repairs ranged from 0 to 11%. Follow-up time varied and was reported in various ways.ConclusionThe incidences of recurrence after groin hernia repair in adolescents were low for both open and laparoscopic mesh and non-mesh repairs. Rates of postoperative chronic pain were low.Trial registrationPROSPERO: CRD42022130554.

P-070 ROLE OF MESH AUGMENTATION IN TRAM FLAP DEFECTS AFTER BREAST RECONSTRUCTION: LITERATURE REVIEW

Abstract Aim The aim of this study was to assess the problem of hernia occurrence in patients after transverse rectus abdominis flap in breast reconstructive surgery and the influence of using donor site reinforcement with mesh to prevent bulging and hernia. Method Literature searches were performed using databases, using key terms to include related articles in the last ten years. Results Out of 65 articles found by the research, 7 articles included in this review, risk factors were identified as obesity, smoking, unipedicule vs bipedicle, mesh vs non-mesh repair. 5 of the included articles involved retrospective study with 6 to 160 patients and follow up period 6 to 48 months, one double blinded study and one was cost utility study retrospective. it is showed that TRAM reconstruction associated with hernia in 18% and 63% had abdominal bulging. using mesh reinforcement reducing bulging 2% to 6% and hernia to 1% to 2%, Consideration should be given particularly in high-risk populations. Conclusion Although the literature about the best way to deal with TRAM defect has not been published yet, this review shows the important of mesh augmentation, it magnified the effect of that on patient with high risk for hernia or bulging.

P-097 FEMORAL AND OBTURATOR HERNIA INCARCERATED: A CASE REPORT

Abstract Obturator hernia is a very rare type of abdominal wall hernia, accounting for less than 1% of all abdominal wall hernias. They can be confused with femoral hernias as well as they can arise simultaneously, just like in this clinical case. A 82 year old female, with multiple comorbidities including a right inguinal hernioplasty, was brought to our emergency department complaining of abdominal pain, distension and vomiting in the last 24 hours. On physical examination, there where abnormally active, high-pitched bowel sounds, abdominal distension and pain on left lower quadrant but no tenderness. Palpation of groin area showed an incarcerated left femoral hernia, apparently containing only omentum. As the patient maintained left lower abdominal pain, we proceed to a CT scan, which demonstrated small bowel dilation with air-fluid levels consistent with a small bowel obstruction originating from an obturator hernia. Open tension-free mesh repair of femoral hernia was done and no need for ressection since it only contained omentum, without ischemic signs. Open transperitoneal nonmesh repair of obturator hernia was performed after hernia reduction. There was no irreversible ischemia. Evolution during hospitalization was uneventful. Regarding obturator hernias, there is no optimal approach since it is a very rare type of hernia, so it probably depends on patient condition and surgeon experience. A transperitoneal approach is preferred when there's signs of bowel obstruction, as we proceed on this clinical case.

AN OBSERVATION ON DESARDA TECHNIQUE OF INGUINAL HERNIA REPAIR

Background: Inguinal hernia repair is one of the most commonly performed procedure in surgical practice throughout the world. The non-mesh repair technique of inguinal hernia by Mohan P. Desarda is becoming popular nowadays. Study of the outcomes of the procedure and comparison with other workers is desirable for wider acceptance of the procedure. To study the Objective: outcomes of inguinal hernia repair by Desarda technique. This is an observational study of 32 patients with inguinal hernia repair by Desarda techn Methodology: ique carried out in Dept. of general surgery, Patna Medical College and Hospital, Patna from October 2020 to October 2022. Out of 32 patients included in the study 18 Result: right sided,12 left sided and 2 bilateral inguinal hernia was there. The mean age of study population was 42.72±12.137 years. Mean operating time was found to be 60.81±10.91 minutes. Majority (87.5%) of the patients experienced moderate pain (measured by VAS ) on the rst post-operative day which gradually decreased with the time. Different postoperative complications ; hematoma in 1 patient (3.125%), seroma in 2 patients (6.25%), surgical site infection in 1 patient (3.125%), scrotal swelling in 2 patients (6.125%) and cord swelling in 1 patient (3.125%) were seen. Conclusion: Non mesh Desarda repair of inguinal hernia repair is associated with less operating time, early ambulation, less post operative pain and complication. As it doesn't use mesh so it is cost effective also and should denitely be encouraged.
