Introduction Among liver transplant recipients, Roux-en-Y gastric bypass (RYGB) may lead to postoperative malnutrition and nutrient deficiencies. Procedures such as the endoscopic ultrasound-directed transgastric ERCP (EDGE) can result in advantageous weight gain for liver transplant recipients with prior RYGB who do not respond to enteral or parenteral nutritional interventions. Methods We present three patients who underwent EDGE for post-transplant malnutrition and weight loss. Results EDGE resulted in weight gain across all patients. Liver transplant recipients with a history of RYGB may be at significant nutritional risk following transplant due to fat malabsorption, underestimation of resting energy expenditure, and appetite suppression mediated by neurohormonal signals. Conclusion When traditional nutritional interventions are unsuccessful, the EDGE procedure may be an effective alternative to promote post-transplant weight gain in this unique population.
