The foreign body is usually directly inserted into the rectum, but an ingested foreign body may also become trapped in the rectum. The most common and serious complication of a rectal foreign body is perforation of the rectum or sigmoid colon. Perforation superior to the peritoneal reflection is associated with intraperitoneal free air and peritoneal signs. Perforation inferior to the peritoneal reflection often causes retroperitoneal injuries and presents with more nonspecific complaints. Determine the size, shape, and number of objects to assess the risk of perforation. In children, rectal foreign bodies usually present as rectal bleeding. Imaging is indicated if there are significant concerns for perforation.
