19. General Overview of the Laparoscopic Roux-en-Y Gastric Bypass
Department of General Surgery, Rowan University, Stratford, NJ, USA
The laparoscopic Roux-en-Y gastric bypass (LRYGB) is both a restrictive and malabsorptive procedure. Patients are placed under general anesthesia for the procedure. During the procedure, the stomach is made into a very small pouch. This is the restrictive part of the procedure by reducing the amount of food that can be consumed during meals. Once the stomach is stapled into a small pouch, the antrum, pylorus, duodenum, and 40 cm of the jejunum are divided. The jejunum at this point is attached to the stomach. The bypassed duodenum is then attached to the jejunum 80–150 cm from its site of attachment to the stomach. This is where Roux-en-Y gastric bypass got its name . This is the malabsorptive part of the procedure.
