Introduction: With obesity on the rise, more patients with a higher body mass index (BMI) are likely to require incisional hernia repairs. The aim of this study is to evaluate the impact of BMI on outcomes of laparoscopic ventral hernia repair.

Methods: We retrospectively reviewed the laparoscopic ventral hernia repairs performed from 2002 to 2009 at a single institution. We divided the patients into two groups; BMI≤30 kg/m2 and BMI>30 kg/m2. We looked at demographics, operative time, whether the hernia was an initial or a recurrent hernia, morbidity, and mortality.

Results: We had a total of 308 cases who qualified for this study.

Conclusions: Laparoscopic ventral hernia repair can be successfully performed in the obese population with increases in complication and recurrence rate, that were not significantly different based on this sample size.
