Background: Laparoscopic Roux-en-Y Gastric By-pass (LRYGB) is not always feasible due to intraoperative difficulties, necessitating a change during surgical procedure. Non-contrast abdominal CT scans is not recommended before bariatric surgery but could be informative and very few studies have evaluated the relevance of these scans. The primary objective was to identify CT scan criteria that could predict a change in the intraoperative therapeutic strategy during LRYGB. Secondary objectives included identifying clinical data associated with change of intraoperative strategy, the impact of surgeon's experience and evaluate postoperative complications. Methods: The study was conducted in University Hospital of Nancy, France between October 2012 and December 2022. This retrospective matched-case-control study (1:3) compared patients with intraoperative change of strategy when LRYGB was initially planned (study group) versus matched patients who undergone LRYGB. Clinical, scannographic, surgical experience and postoperative complications data were collected in the two groups.
