A multicenter experience of through-the-scope balloon-assisted enteroscopy in surgically altered gastrointestinal anatomy

摘要

Background Surgically altered gastrointestinal anatomy poses challenges for deep enteroscopy. Current overtube-assisted methods have long procedure times and utilize endoscopes with smaller working channels that preclude use of standard accessories. A through-the-scope balloon-assisted enteroscopy (TTS-BAE) device uses standard endoscopes with a large working channel to allow metallic and plastic stent insertion. We aim to determine the efficacy and safety of TTS-BAE in patients with altered surgical anatomy.
