Abstract:
Data is limited regarding the success and safety of percutaneous endoscopic gastrostomy (PEG) placements by single balloon enteroscopy (SBE) in patients with Roux-en-Y gastric bypass (RNY-GB) anatomy. We report on 23 cases of PEG placements by SBE with overall technical success of reaching the excluded stomach 70% and with PEG placement success rate of 69%. No intra-procedural adverse events occurred. This technique seems safe when feasible for PEG placement in patients with RNY-GB anatomy.
