Mortality and Hospital Stay After Bariatric Surgery in 2,167 Patients: Influence of the Surgeon Expertise

摘要

Postoperative mortality is a rare event after bariatric surgery. The main goal of this study was to calculate the 30-day mortality rate postbariatric “open” surgery and the length of hospital stay of patients assisted by a health maintenance organization in Brazil. We also investigate their association with sex, age, BMI, preexisting comorbidities, and volume of procedures performed by surgeons.
