30-Day Morbidity and Mortality of Bariatric Surgery During the COVID-19 Pandemic: a Multinational Cohort Study of 7704 Patients from 42 Countries.

Background: There are data on the safety of cancer surgery and the efficacy of preventive strategies on the prevention of postoperative symptomatic COVID-19 in these patients. But there is little such data for any elective surgery. The main objectives of this study were to examine the safety of bariatric surgery (BS) during the coronavirus disease 2019 (COVID-19) pandemic and to determine the efficacy of perioperative COVID-19 protective strategies on postoperative symptomatic COVID-19 rates.

One anastomosis gastric bypass vs. Roux-en-Y gastric bypass: a 5-year follow-up prospective randomized trial.

Background: One anastomosis gastric bypass (OAGB) is a relatively novel technique with excellent outcomes, comparable to most accepted procedures. Our aim was to compare OAGB and Roux-en-Y gastric bypass (RYGB) in terms of percent of excess weight lost (%EWL) and resolution of comorbidities.

Methods: Thirty-three patients were randomly assigned (1:2) to two groups (OAGB = 9 and RYGB = 24).
