ERCP with retrieval balloon-assisted enterography using traditional duodenoscope in post-GI surgery patients

摘要

ERCP in patients who have undergone GI surgery is difficult because of the anatomic changes in the digestive tract. Several case series have reported that successful cannulation was achieved by use of a front-viewing endoscope,1 a single-balloon enteroscope, or a double-balloon enteroscope.There are a few reported cases of using a conventional duodenoscope to perform cannulation in patients after GI surgery.
