Hematochezia caused by colonic perforation of a drain, a rare cause of lower gastrointestinal bleeding. A case report

Abstract Intra-abdominal drains are often placed during surgical procedures to prevent the formation of intra-abdominal collections and to aid early detection of leaks and hemorrhage. However, on many occasions, they can cause complications, including pain, bleeding, infection, and, on rare occasions, they can erode into the bowel, causing obstruction and even perforation. When this happens, prompt treatment is needed, as the drain can now cause severe morbidity and mortality if there is no active surveillance. Therefore, surgeons must employ an individualized approach when using drains, accounting for the specific characteristics of each surgery. We present the case of an 84-year-old patient who had a drain placed after a complicated appendicitis. After discharge, he presented with hematochezia, and after prompt evaluation, the drain was seen inside the cecum. He was successfully treated and, on follow-ups, is doing well.
