A patient who presented with massive upper gastrointestinal hemorrhage underwent a Billroth II partial gastrectomy. He developed efferent loop obstruction due to a retained abdominal drain. Relaparotomy for removal of drain was performed. Retained drains are known complications but rarely, it is cause of efferent loop obstruction.
