How is the RNY Surgery done?

A lot of AMOS members already know how this proceedure is done. I am posting this info for those members that DO NOT know. ------------------- Roux-en-Y: How the Divided Gastric Bypass is Performed 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 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 functional portion of the stomach, while the large lower segment connected to the duodenum becomes the non-functioning portion of the stomach. 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. Following the gastro-jejunostomy anastomosis (connection), the jejunum is then reconnected in the shape of a "Y" (hence, the name Roux-en-Y) by means of another anastomosis about 25 inches below the first. Secretions form the lower, non nonfunctional segment of the stomach and the duodenum empty into the jejunum well below the upper (gastro-jejunostomy) anastomosis. Thus, food ingested through the small upper stomach pouch will mix with secretions from the lower stomach pouch and duodenum at this point. From here on, digestion and absorption of food nutrients are carried on in a completely normal fashion.
