Laparoscopic Revision of Omega Loop Bypass to Roux-en-Y Gastric Bypass

Bariatric surgeons who evaluate patients for possible revisional surgery should be aware of the potential of aberrant bypass anatomy. The “Omega loop gastric bypass” is a nondivided, antecolic loop gastric bypass with a Braun entero-enterostomy. The omega loop bypass is not a condoned weight loss procedure due to the lack of published evidence regarding risks and benefit. We present a patient who underwent a “gastric bypass” procedure that presented to our office with chronic abdominal pain.

In this video, we discuss the importance of surgeon-performed endoscopic evaluation combined with upper GI contrast studies to evaluate the anatomy of patients presenting for possible revisional surgery. We also discuss the potential complications associated with loop bypass procedures.

Our video demonstrates a minimally invasive technique to revise an Omega loop bypass into a Roux-en-Y gastric bypass by resecting the afferent limb of the Omega loop.
