Sponsor's own description
Aim: To define benchmark outcomes in minimally-invasive primary bariatric surgery. Design: Multicenter retrospective cohort study. Assessed outcomes: Morbidity as defined by the Clavien-Dindo classification for surgical complications, the Comprehensive Complication Index® (CCI®) at discharge, at 3 months and at latest follow-up. Evolution of body mass index (BMI) will be also analyzed. Hospital eligibility: High volume centers (\> 200 bariatric operations per year) from at least three continents, maintaining a prospective database, as well as having published previously critically on their outcome. Study population: Adult patients who underwent primary minimally invasive (laparoscopic / robotic) Roux-en-Y gastric bypass or sleeve gastrectomy from 1st of June 2012 to 31st of May 2017. Patient Exclusion criteria: detailed later. Data collection Deadline: 1st September 2017 - 30 April 2018
