Animation of the gastric bypass

This is a video animation describing how the laparoscopic gastric bypass surgery alters the gut to reduce food intake.

Laparoscopic gastric bypass – PART I

This video shows you how Dr. Christou performs the first half (the “lower end”) of the laparoscopic gastric bypass procedure. This part involves exposing the back part of the stomach (the lesser sac), identifying the small bowel to be bypassed, the creation of the jejunojejunostomy and secure closure of all potential defects where small bowel can be trapped and cause an internal hernia.

Laparoscopic gastric bypass – Part II

This video shows you how Dr. Christou performs the second half (the “upper end”) of the laparoscopic gastric bypass procedure. This part involves creation of the 7-10 ml gastric pouch, the gastrojejunostomy (joining the pouch to the small intestine) and testing for leaks.

How the laparoscopic gastric bypass works

This video shows you an animation narrated by Dr. Christou explaining how the digestive system is changed by the gastric bypass and how it helps the patient eat less and lose weight.

Reversal of a gastric bypass by laparoscopy

This video shows Dr. Christou reversing a laparoscopic gastric bypass in a patient with severe emotional disturbance 2 years after his original gastric bypass. This potential complication was not identified at the psychological screening before his original surgery.

Conversion of a failed gastric banding to laparoscopic Roux-en-Y gastric bypass

This man originally requested laparoscopic adjustable gastric banding. He only managed to lose about 5% of his extra weight 2 years later. His diabetes was getting worse so he requested conversion to laparoscopic RY gastric bypass. Two years after the conversion he has lost 86% of his extra weight and his diabetes is resolved.
