Abstract

Background Gallbladder management in bariatric surgery varies. Some surgeons perform routine cholecystectomy with bariatric surgery, and others selectively base that decision on routine preoperative ultrasound findings. Both approaches treat bariatric patients differently than the normal-weight population in whom cholecystectomy is not performed in asymptomatic patients. We hypothesized that it is possible to apply the commonly used indications for cholecystectomy in the nonobese population safely to a Roux-en-Y gastric bypass cohort. Methods Data were collected prospectively and retrospectively on consecutive patients at our center undergoing Roux-en-Y gastric bypass from April 1, 2003 to March 31, 2004. Asymptomatic patients underwent neither preoperative gallbladder ultrasonography nor concomitant cholecystectomy. Age, body mass index, gender, length of follow-up, compliance to ursodiol therapy for 6 months, need for subsequent cholecystectomy, complications, and pathologic diagnoses were recorded. Results A total of 692 primary Roux-en-Y gastric bypass procedures were performed, of which 661 (95.5%) were completed laparoscopically. Complete data were collected on 417 patients (60.3%). A total of 98 patients (23.5%) had had prior or concomitant cholecystectomy and were excluded from additional study. Of the remaining 319 patients, 47 (14.7%) required subsequent cholecystectomy and 272 (85.3%) did not. The risk of subsequent cholecystectomy correlated inversely with the dur…

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.
