Core Tip	Rectal foreign bodies (RFBs) are occasionally encountered, and most cases involve self-insertion for sexual pleasure. They are common in young male patients, and because patients often delay seeking medical attention due to embarrassment, complications such as perforation and peritonitis may already be present at diagnosis. Physicians must remain mindful of the possibility of RFB insertion and conduct history-taking and physical examinations with sensitivity to patient embarrassment. We report the first case of penetrating peritonitis caused by long-term RFB retention, which did not present as an acute abdomen because the perforation was confined to the retroperitoneal space.
