Roux-en-Y gastric bypass

a treatment for morbid obesity consisting of surgical division of the small intestine to form two arms. The jejunum is attached to a stoma into a gastric pouch, and the bypassed duodenum connects the pylorus with an end-to-side anastomosis into the lower jejunum.

Roux-en-y gastric bypass

A bariatric surgical procedure in which the superior portion of the stomach is isolated from the rest of the stomach and the jejunum is connected to it. As a result, food passes directly from the proximal stomach into the middle of the small intestine. It bypasses the majority of the stomach, which is isolated from the working portion of the stomach and from the duodenum. An opening is made in the duodenum and the jejunum, and the two organs are connected via a surgical stoma. This permits drainage into the jejunum of gastric secretions from the isolated greater curvature of the stomach. This form of gastric bypass is the most common bariatric surgical procedure and among the most successful. Since the duodenum absorbs many important vitamins and nutrients, including iron, vitamin B12, and calcium, nutritional deficiencies and iron-deficiency anemia are common complications. Others include nausea, vomiting, ulcers, and anastomotic leaks.
