While metabolic-bariatric surgery is a safe and well-established surgery, complications do occur and can have significant impact on the patient. With the study, the investigators aim to establish the proportion of patients that will have complications and understand what the impact of complications are on costs.
Complications after metabolic-bariatric surgery can be catastrophic and have significant impact on costs, morbidity, and mortality. As current global benchmarks for complications rates in MBS are based on standard risk patients in western populations, the benchmark complication rates in high-risk patients and Asian populations are unknown. The investigators aim to evaluate the incidence of complications in 1016 consecutive patients and the impact of complications on costs.
Study Type
OBSERVATIONAL
Enrollment
1,016
Our study is conducted in a predominantly high-risk Asian population that will be undergoing metabolic-bariatric surgery. The types of surgery can be divided into Laparoscopic Sleeve Gastrectomy (LSG), Roux-en-Y Gastric Bypass (RYGB) or One-Anastomosis Gastric Bypass (OAGB).
