Acute gastric remnant bleeding is an exceptionally rare complication when it occurs long after bariatric surgery. We present the case of a patient with a bleeding ulcer of the excluded stomach (i.e., the remnant), occurring 7 years after Roux-en-Y gastric bypass (RYGB) for morbid obesity. A computed tomography scan managed to locate the active bleeding source in the gastric remnant. During emergency laparotomy, a bleeding ulcer of the fundic region of the excluded stomach was identified. Total resection of the remnant was performed, with good post-operative recovery. To the best of our knowledge, this is the first full report of a significantly delayed haemorrhagic ulcer of the gastric remnant, occurring years after RYGB.
