Background
Currently, there’s not a well-accepted optimal approach for umbilical hernia repair in patients with obesity when comparing laparoscopic umbilical hernia repair (LUHR) versus open umbilical hernia repair (OUHR).
Objective
The objective of this study was to evaluate if there’s a difference in postoperative complications after LUHR versus OUHR with the goal of indicating an optimal approach.
Methods
A retrospective analysis was completed using the 2016 National Surgical Quality Improvement Program (NSQIP) database to identify patients with obesity (Body Mass Index (BMI) ≥ 30 kg/m2) who underwent LUHR or OUHR. Patients were divided into OUHR and LUHR groups, and post-operative outcomes were compared, focusing on wound complications.
Results
A total of 12,026 patients with obesity who underwent umbilical hernia repair were identified; 9695 underwent OUHR, while 2331 underwent LUHR. The LUHR group was found to have a statistically significant higher BMI (37.5 kg/m2 vs. 36.1 kg/m2; p < 0.01) and higher incidence of diabetes mellitus requiring therapy (18.4% vs. 15.8%; p < 0.01), hypertension (47.5% vs. 43.8%; p < 0.01), and current smoker status (18.6% vs. 16.5%; p < 0.02). Superficial surgical site infection (SSI) was significantly higher in the OUHR group (1.5% vs. 0.9%; p < 0.03), and there was a trend towards higher deep SSI in the OUHR group (0.3% vs. 0.5%; p = 0.147). There was no difference in organ space SSI, wound disruption, or return to OR. On logistic regression, composite SSI rate (defined as superficial, deep, and organ space SSIs) was significantly increased in the OUHR group (p < 0.01). Predictive factors significantly associated with increased morbidity included female gender and higher BMI.
Conclusions
In patients with obesity, even though the LUHR group had an overall higher BMI and higher rates of diabetes, hypertension, and current smoking status, they experienced decreased post-operative wound complications compared to the OUHR group.
