Developing the Laparoscopic Gastric Bypass

  • Cássio Renato Montenegro de Lima


Bariatric surgery remains the only effective and enduring treatment for morbid obesity, which includes gastric bypass. The principles of gastric bypass surgery were developed by Mason and Ito in 1967 and have become the gold standard procedure in bariatric surgery. The first laparoscopic approach to Roux-en-Y gastric bypass (LRYGB) was described by Wittgrove. Nowadays, LRYGB is now utilized in approximately 90% of all gastric bypass procedures.

A laparoscopic approach has significant potential to reduce perioperative complications and recovery time. It reduces postoperative pain, allows faster recovery, diminished parameters of systemic injury, showed a dramatic reduction in the frequency of wound infection, and delayed ventral hernias.

Laparoscopic gastric bypass is a technically feasible procedure, which can be accomplished with acceptable morbidity, reasonable operating times, and excellent clinical results. It deserves a place in the operative repertoir of modern bariatric surgeons.

Gastric bypass has evolved over the 30 years following its initial description to include multiple modifications. On modern times, the laparoscopic approach is technically challenging but with experience can be mastered. Not only the surgeon but the whole team needs to be familiar with the special setting.

Varying techniques have been performed to the development of gastric bypass, but the anatomic and physiologic principles of the gastric bypass operation were identical between open and laparoscopic techniques. Evidences suggest that long-term weight loss is similar between open and laparoscopic techinques.
