Figure 1. Diagram of gastric bypass anatomy shows a small gastric pouch (GP) created with stapling (dotted line) of the stomach; anastomosis of the pouch to a Roux-en-Y limb (straight thick black arrows); route of gastric contents to the efferent loop (white arrows); oversewn jejunal loop (curved arrow), or blind loop, of the Roux-en-Y limb; and jejunojejunal anastomosis (thin black arrows).
