Abstract
Accessing the bypassed portion of the stomach via conventional endoscopy is difficult following Roux-en-Y gastric bypass surgery. However, endoscopic examination of the stomach and small bowel is possible through percutaneous access into the bypassed stomach (BS) with a combined radiologic and endoscopic technique. We present a case of obscure overt gastrointestinal (GI) bleeding where the source of bleeding was thought to be from the BS. After conventional endoscopic methods failed to examine the BS, percutaneous endoscopy (PE) was used as an alternative to surgical exploration.
