Richter's hernia: an unusual presentation.

: Richter's Hernia is an unusual form of herniation. The incarceration accompanying the hernia invariably leads to bowel ischemia. Chronic incarceration of the antimesenteric border of the intestine, presenting with a long-standing history of signs and symptoms with no dire consequences is unusual. We present a case with a typical acute presentation, and the only case we are aware of with a chronic incarceration leading to a true diverticulum of the hepatic flexure.
