Weight regain after Laparoscopic Sleeve Gastrectomy (LSG) is nowadays a growing concern. Sleeve dilatation and loss of food restriction is considered the main mechanism. The placement of a silicon ring around the gastric tube seems to give benefits in the short-term.

The Investigators evaluate the efficacy of banded sleeve gastrectomy compared to standard sleeve in the mid-term.

Fifty patients were randomized between LSG and Laparoscopic Banded Sleeve Gastrectomy (LBSG), and they underwent a mean follow-up of 4 years.

Patients' management was exactly the same, apart from the band placement. After surgery differences in weight loss, operative time, complication rate and mortality were analyzed.
