Divided Gastric Bypass Procedure
The divided gastric bypass with Roux-en-Y gastro-jejunostomy consists of separating the stomach into two sections using parallel rows of titanium staples, with many of the staples additionally over-sewn or secured with sutures as needed. The staples remain fixed and do not migrate. The small upper segment connected to the esophagus remains the food-functional portion of the stomach, while the large lower segment connected to the duodenum, though still functional, does not deal with food eaten by the patient.
In the next phase, the surgeon disconnects the continuity of the small intestine (upper jejunum) and brings the lower end up to the small gastric pouch still connected with the esophagus. This section of the intestine is still functional. The intestine is connected to this small stomach pouch by means of an opening about the size of a dime. This allows food to pass directly into the intestine where it is digested. This is called a gastro-jejunostomy.
