Figure 1 Roux-en-Y Procedure

Diagram of Roux-en-Y gastric bypass surgery. In this procedure, a small stomach pouch is created at the gastroesophageal junction (arrow, A), resulting in restricted intake. In addition, the jejunum is brought up and sewn to the new stomach pouch (arrow, B), bypassing the majority of the absorptive stomach and duodenum, creating a mildly malabsorptive state. The proximal jejunum is then anastamosed to the side of the distal jejunum (arrow, C), creating the jejunojejunostomy and allowing for egress of secretory fluids and bile acids.
