Abstract

Introduction: While previous studies have documented adverse outcomes among obese patients undergoing ventral and inguinal hernia repairs, there is a lack of literature regarding the impact of obesity on parastomal hernia (PSH) repair. This retrospective study aims to determine the value of obesity stratification in predicting postoperative complications in patients undergoing PSH repair. Materials and methods: Outcomes of elective PSH repairs from 2010 to 2020 in the American College of Surgeons National Surgical Quality Improvement Program database were analyzed. Patient demographics, preoperative characteristics, and postoperative outcomes were compared using bivariate analysis and multivariable regression models. Results: A total of 2972 patients were retrospectively analyzed. Multivariable regression found, compared to nonobese patients, patients of obesity class ≥ II were 1.37 times more likely to develop complications overall (P = 0.006) and 1.55 times more likely to develop wound complications (P < 0.001). This group also yielded a 1.60 times higher risk of developing superficial wound infection (P = 0.007) and a 1.63 times greater risk of developing postoperative sepsis (P = 0.044). Total length of stay was longer for patients of obesity class ≥ II but not for obesity class I when compared to patients with body mass index <30.0 kg/m2. Conclusions: Patients with a body mass index ≥35.0 kg/m2 are more susceptible to an increased rate of complications after PSH repairs. The findings of this study will allow surgeons to stratify obese patients who would benefit from preoperative weight loss interventions prior to PSH repair and discuss associated risks with patients to facilitate informed consent.
