Ursodeoxycholic acid in the prevention of gallstones in patients subjected to Roux-en-Y gastric bypass1.

Purpose: To evaluate the contribution of ursodeoxycholic acid (UDCA) in the first 12 months after Roux-en-Y gastric bypass in the prevention of gallstone formation.

Methods: A community-based clinical trial was conducted. A total of 137 patients were included in the study; 69 were treated with UDCA, starting 30 days after the surgery, at a dose of 150 mg twice daily (300 mg/day) over a period of 5 consecutive months (GROUP A), and 68 were control patients (GROUP B).

Ports minimization with mini-port and liver flexible retractor: an ergonomic and aesthetic alternative for single port in laparoscopic gastric bypass.

Background: The laparoscopic access, with its classically known benefits, pushed implementation in other components, better ergonomy and aesthetic aspect.

Aim: To minimize the number and diameter of traditional portals using miniport and flexible liver retractor on bariatric surgery.

Method: This prospective study was used in patients with less than 45 kg/m2, with peripheral fat, normal umbilicus implantation, without previous abdominoplasties.
