title: [Pedunculated polyp of the sigmoid. Initial detection by ultrasonography with compressive technique].
abstract: A man with a history of intermittent blood stained feces for 3 years was found with US to have a 3 cm polyp, presumably of the sigmoid colon. Double contrast barium enema and colonoscopy first missed the polyp, which was confirmed with surgery.
