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

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

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

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

Purpose: The study aim was to assess the impact of clinically significant weight loss (CSWL; ≥5% weight reduction) on postoperative complications following abdominal wall reconstruction with the component separation technique (CST).

Methods: A retrospective review of patients who underwent open ventral hernia repair (VHR) with CST from November 2008 to January 2022 was performed. Cohorts were stratified by presence of CSWL from baseline weight at preoperative consultation.

Results: Of 180 total patients, 40 (22.2%) achieved CSWL prior to VHR. Mean age was 59.6 ± 11.2 years. Patients in the CSWL cohort represented a higher average body mass index (BMI) (33.6 vs. 31.7 kg/m², p = 0.076), and were obese more frequently (80.0% vs. 56.4%, p = 0.007). The CSWL cohort had a higher proportion of patients in Ventral Hernia Working Group (VHWG) classification II (82.5% vs. 63.6%) while the non-CSWL cohort had more VHWG classification III/IV (20.0% vs. 10.0%, p = 0.078). Mean follow-up duration was 6.1 ± 13.4 months. Complications, including 30- and 90-day surgical site occurrence (SSO), return to operating room, readmission, and hernia recurrence (CSWL: 5.0% vs. non-CWL 1.4%, p = 0.179), were comparable between cohorts. BMI was an independent predictor of any complication (OR 1.07, p = 0.044) and 90-day SSO (OR 1.10, p = 0.043).

Conclusion: Achievement of CSWL prior to open VHR utilizing CST results in similar post-reconstruction outcomes to patients who maintained a comparable BMI at baseline. Higher day-of-surgery BMI was more consequential to postoperative complications than percent weight loss.

Purpose: To assess sex differences in patient-reported quality of life, pain, and hernia recurrence after adjusting for confounding features of hernia disease in a large national registry one year after ventral hernia repair.

Methods: Data were analyzed retrospectively from the Abdominal Core Health Quality Collaborative national registry from pre-operatively until one year post-operatively. 3,172 patients undergoing elective ventral hernia repair with 1-year follow-up data were included for analysis after propensity score matching (1:1 match; females: mean [interquartile range] age, 60 [49, 68]; body mass index, 32 [27, 36]; males: age, 60 [52, 68]; 31 [28, 35]. The primary outcome of interest between sexes was the Hernia Related Quality of Life survey (HerQLes), and secondary outcome measures included the Patient-Reported Outcomes Measurement Information System Pain Intensity (PROMIS) short form (3a) score and hernia recurrence.

Results: Female sex was associated with worse HerQLes and PROMIS pain 3a scores at 1 year follow up (adjusted mean difference, -2.42, 95% confidence interval (CI) -4.11 to -0.72; p = 0.004; adjusted mean difference, 1.27, 95% CI 0.67 to 1.87; p < 0.001) compared to male sex. Hernia recurrence rates at 1 year were not different between sexes.

Conclusion: Females reported worse quality of life and higher levels of pain at 1-year post ventral hernia repair after accounting for age, BMI, hernia width, and baseline quality of life compared to males. There were no differences between females and males with respect to hernia recurrence at 1-year follow-up, and 1 in 5 patients experienced a recurrence at this time point.

Introduction: Although hernia repair constitutes a significant portion of surgical training, education around more complex hernia concepts such as abdominal wall reconstruction (AWR) or paraesophageal hernia repair may be lacking. We developed and implemented a pre-rotation quiz for residents on an AWR and minimally invasive surgery service. We also investigated the staff and resident perception of resident knowledge and experience of the rotation before and after quiz implementation.

Methods: The multiple-choice quiz questions were written by clinical and research fellows, validated by four staff, two fellows, and two senior residents and implemented in June 2023. Questions assessed knowledge of anatomy, operative steps, mesh materials, clinical trials, and postoperative management specific to ventral, inguinal, and paraesophageal hernia repairs. Residents were notified of the summative quiz three weeks prior and provided with reference materials specific to quiz questions. Anonymous Likert-type surveys were distributed to staff and residents between 3/2023 and 3/2024. Responses were assessed based on the overall score as well as individual domains and then compared based on whether they were completed before or after implementation of the quiz.

Results: 17 seniors and 29 juniors rotated on service and all completed the pre-rotation quiz between 7/1/2023-3/4/2024. The mean first attempt score was 72%(± 12.4%) for junior residents and 88.4%(± 9.6%) for senior residents. Staff reported overall resident knowledge improved after quiz implementation (maximum 90, mean(SD): 46.25(± 8.58) vs. 75.5(± 11.24),p = 0.05). Sixteen(45.7%) residents responded to the survey before quiz implementation and 23(50%) after. Residents only reported improved knowledge regarding current literature (maximum 5, mean(SD):3.2 ± 0.98 vs. 3.8 ± 0.78,p = 0.04).

Conclusion: Implementing a pre-rotation quiz effectively improves staff perception of resident knowledge and preparation.
