SOD should be considered in the differential diagnosis of gastric bypass patients with pancreatobiliary pain after cholecystectomy. When the clinical history is supported by laboratory and magnetic resonance cholangiopancreatography data, TS can be undertaken with low morbidity and good patient outcomes. SOD is a notable disorder in the gastric bypass population. With appropriate patient selection, TS can be beneficial.
