[Two cases of afferent loop syndrome caused by obstruction at the jejuno-jejunostomy site in the Roux-en-Y loop that were successfully treated by endoscopic balloon dilatation].
We report 2 rare cases of afferent loop syndrome caused by obstruction at the jejuno-jejunostomy site in the Roux-en-Y loop after total gastrectomy, which was successfully treated by endoscopic balloon dilatation of the anastomotic stenosis. Case 1: A 62-year-old woman presented with malaise and lower abdominal distension 6 months after laparoscopy-assisted total gastrectomy with Roux-en-Y reconstruction. She was diagnosed with afferent loop syndrome; CT imaging indicated marked dilatation of the afferent loop, with membranous obstruction at the jejuno-jejunostomy site in the Roux-en-Y loop. Although almost complete occlusion was noted at the jejuno-jejunostomy site, the obstruction was successfully relieved by endoscopic balloon dilation using TandemTM XL Triple Lumen ERCP Cannula (Boston Scientific)®. Case 2: A 70-year-old man presented with malaise and lower abdominal distension 3 years after laparoscopy-assisted total gastrectomy with Roux-en-Y reconstruction. He was diagnosed with afferent loop syndrome; CT imaging indicated complete obstruction at the jejuno-jejunostomy site in the Roux-en-Y loop. As in case 1, the obstruction was successfully treated by endoscopic balloon dilatation of the occluded anastomosis.
