Indocyanine green (ICG) is a nontoxic, fluorescent iodide dye with rapid hepatic clearance that has been used in medical applications since the mid-1950s. In abdominal surgery, ICG can be used to identify anatomical structures such as the biliary tract, urinary tract, blood vessels, tissue perfusion on different organs, or anastomosis in the digestive system. The application of ICG during bariatric surgery may be useful in primary and revisional procedures at different steps of the surgery.

Roux-en-Y gastric bypass (RYGB) is one of the best procedures for the treatment of obesity and associated comorbidities. However, the percent of revisional procedures after a gastric bypass by weight regain has been increased, therefore several surgical options are available for the treatment of weight regain. In this case report, we combined a biliary limb distalization with endoscopic transoral outlet reduction (eTOR).

RYGB represents one of the best alternatives for weight loss in obese patients achieving a weight loss of up to 60% and a resolution of comorbidities of 70%. Revision surgery contemplates multiple techniques including the conversion from one surgical technique to another, structural changes to the primary technique, among others. GERD is now a long-term problem for patients who have undergone LGS.
