Background and Study Aims: Endoscopic evaluation of the excluded stomach after Roux-en-Y gastric bypass surgery for morbid obesity is a challenge, and the pathological changes that take place in the bypassed stomach are unclear. A new double-balloon method of evaluating the bypassed stomach after Roux-en-Y gastric bypass surgery for morbid obesity is described here.
Patients and Methods: This new enteroscope uses two balloons, one attached to the tip of the endoscope and the other to the distal end of the soft overtube. The procedures were carried out in six patients using the retrograde route, through the end-to-side jejunal anastomosis via the duodenobiliopancreatic limb up to the bypassed stomach.
Results: The bypassed stomach was reached in five of six patients (83.3 %). An endoscopic appearance of atrophic gastritis was found in three patients, mild in two cases and severe in one case with intestinal metaplasia. Erosive and hemorrhagic gastritis was found in two patients.
Conclusions: Endoscopic evaluation of the bypassed stomach via the retrograde route after Roux-en-Y gastric bypass for morbid obesity is feasible using the double-balloon enteroscope.
