Abdominal Wall Hernia and Metabolic Bariatric Surgery.

Abstract

The management of morbidly obese patients with a concomitant ventral hernia (VH) is a great challenge for surgeons. There is controversy over the optimal strategy to tackle both health problems, requiring an individualized approach. Obese patients have a higher recurrence rate after hernia repair, and bariatric surgery in the presence of a VH can be difficult. As morbid obesity is related with severe comorbidities, including increased cardiovascular and anesthetic risks, some advocate for a single-stage strategy. A primary hernia repair carried out during the bariatric surgery, however, may increase morbidity without definitively solving the problem. Biological meshes are expensive and also have a high recurrence rate. The laparoscopic placement of a synthetic mesh offers good results, but it is worrisome because bariatric surgery is a clean-contaminated procedure. Moreover, there is a great chance that a plastic surgery would be necessary after completing the weight-loss process, and the abdominal wall surgery could be performed at that point. There are many arguments, but the evidence is weak. We present an extensive review of the currently available literature on the management of VH in morbidly obese patients. We aim to provide objective information regarding the pros and cons of the different strategies that have been proposed, to facilitate the selection of the best approach to individual morbidly obese patients with abdominal wall hernias precising both of surgical repair.
