Purpose: Pre-optimization of obese patients prior to abdominal wall reconstruction (AWR) is essential in mitigating their increased preoperative risks. Traditionally diet, exercising, bariatric surgery are the tools typically prescribed for weight loss. The advent of glucagon-like peptide-1 agonists (GLP-1A) which stimulate insulin secretion and inhibit gastric emptying have improved the weight loss armamentarium. However, there is a limited amount of literature on GLP-1A effectiveness and postoperative outcomes in AWR patients. This study compares the efficacy of GLP-1A to Bariatric Surgery (BAS) in perioperative AWR patient. Methods: A prospectively maintained database was retrospectively reviewed to identify all patients undergoing AWR at our institution between January 2021 and March 2024. We included patients who required GLP-1A or BAS for weight optimization prior to AWR. We excluded patients on GLP1-A or history BAS not performed for AWR preoptimization. Basic demographics such as age, sex, race, weight and BMI at initial clinic visit and at surgery were compared. Primary endpoints included time to surgery, time to bowel recovery and length of stay (LOS). Time to surgery was defined as the number of months between the initial clinic visit and AWR. Time to bowel recovery was defined as the number of days it took for the first postoperative bowel function. Secondary endpoints included standard 30-days postoperative variables. Nominal variables were analyzed using a Fisher exact test and continuous variables were analyzed with Student's T test. Results: 35 patients were included in this study (GLP-1A: 17, BAS: 18). The GLP-1A cohort had a lesser BMI at the initial clinic visit (40.8 vs 43.4, p = 0.188). GLP-1A cohort made it to the operating room faster (9.1 months vs 13.5 months, p = 0.06) from the first clinic visit; and (7.9 months vs 9.7 months, p = 0.4) from initiation of weight loss intervention. Albeit losing less weight (14.9 kg vs 27.1 kg, p = 0.008) with a lesser reduction in the BMI (4.69 vs 9.23, p = 0.004). The GLP-1A cohort showed a non-significant elevated LOS (5.2 days vs 3.6 days, p = 0.25) and an increased ileus rate (17.6% vs 0%, p = 0.1). However, there were no differences noted in time to bowel recovery (2.9 days vs 3.1 days, p = 0.76). Conclusion: GLP-1A is effective in optimizing patients needing weight loss before AWR. They shorten the timeline to AWR intervention and have comparable peri-operative outcomes to BAS patients. [ABSTRACT FROM AUTHOR]

Barrier-coated meshes were designed to reduce adhesion formation between mesh and the surrounding viscera. There have been questions raised but little data to determine if rapidly absorbable coatings pose an increased risk of infection. The objective of this study was to determine if a difference exists in wound and mesh infection rates between coated and uncoated polypropylene mesh in patients undergoing open ventral hernia repair. A prospective, institutional database at a tertiary hernia center identified patients undergoing open preperitoneal ventral hernia repair (OPPVHR) with polypropylene mesh in CDC class 1 and 2 wounds. Using propensity score matching, an absorbable, coated and uncoated group were matched based on age, comorbidities, wound class, defect size, and mesh size. There were 265 patients each in the matched coated and uncoated mesh groups for a total of 530 patients. Postoperative wound infections (10.9% versus 4.6%, P = 0.01) and need for IV antibiotics (10.5% versus 4.3%, P = 0.01) were significantly higher in the coated group. There was an increase in mesh infection for the coated group (3.4% versus 0.4%, P = 0.02), and of those developing a mesh infection, 60.0% eventually required mesh excision. Coated mesh was associated with increased postoperative wound and mesh infection following OPPVHR. An uncoated mesh should be strongly considered when placed in an extraperitoneal location.

Traumatic abdominal wall hernias and abdominal Morel-Lavallee lesions rarely occur in blunt abdominal trauma. There are only a few documented cases of these occurring simultaneously, especially in the pediatric population. We report a case of a 15-year-old boy with a concomitant traumatic abdominal wall hernia and Morel-Lavallee lesions. Abdominal wall reconstruction was performed successfully via the collaboration of trauma, minimally invasive surgery, and plastic surgery teams. [ABSTRACT FROM AUTHOR]
