Abstract

Purpose The anatomic rearrangement of the gastrointestinal tract after bariatric surgery may result in alterations in the bile acid pool and consequently, gallstone disease. We aimed to investigate whether patients undergoing bariatric surgery are at risk of developing gallbladder disease postoperatively. Patients and methods We conducted a population-based cohort study by using claims data from the Taiwan National Health Insurance Research Database. The study cohort comprised 4197 patients diagnosed with morbid obesity. Results Among the morbidly obese patients, 2698 underwent bariatric surgery. Females and younger subjects were more prevalent in the surgical group than non-surgical group. Bariatric surgery reduced all obesity-related comorbidities. Cox proportional hazards regression was performed, which revealed increased risk of cholecystectomy after bariatric surgery among obese patients (adjusted hazard ratio, 3.43; p=0.0165). After adjusting for sex and age, the incidence of cholecystectomy was increased in the females population (adjusted hazard ratio, 3.74; p Conclusion Based on the Taiwan database population-based cohort study, bariatric surgery increases the risk of cholecystectomy among morbidly obese patients, especially in the female population and patients aged 30-64 years.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
