Our large multicenter study indicates that LA-ERCP in patients with RYGB is feasible with a high procedure success rate comparable with that of standard ERCP in patients with normal anatomy. The ERCP-related adverse events rate is comparable with conventional ERCP, but the overall adverse event rate was higher because of the added laparoscopy-related events.

Despite national recommendations for use of split-dose bowel purgatives, many practices are still relying on single-dose preparations. Clear liquid diets are widely recommended for the day prior to the colonoscopy, despite a lack of data to support the need for such a strict dietary regimen. Patients receive disparate instructions regarding the management of their medications. These findings suggest a need for more evidence-based and comprehensive colonoscopy preparation instructions.
