Abdominal distention is commonly massive and characteristically tympanitic over the gas-filled, thin-walled colon loop. Overlying or rebound tenderness raises the concern of peritonitis due to ischemic or perforated bowel. The patient may have a history of episodes of acute volvulus that spontaneously resolved; in such circumstances, marked abdominal distention with minimal tenderness may occur.
