A prospective randomized study comparing patients with morbid obesity submitted to sleeve gastrectomy with or without omentectomy.

Background: Increased visceral adipose tissue is a risk factor for the metabolic complications associated with obesity and promotes a low-grade chronic inflammatory process. Resection of the great omentum in patients submitted to a bariatric procedure has been proposed for the amelioration of metabolic alterations and the maximization of weight loss. The aim of the present study was to investigate the impact of omentectomy performed in patients with morbid obesity undergoing sleeve gastrectomy (SG) on metabolic profile, adipokine secretion, inflammatory status, and weight loss.
