与明亮的、粉红色的、有活力的肠相比梗死的小肠呈暗红色，梗死是由于手术后发生粘连导致的绞榨性疝。梗死的肠已经失去了血液供应。
The dark red infarcted small intestine contrasts with the light pink viable bowel. The forceps extend through an internal hernia in which a loop of bowel and mesentery has been caught. This is one complication of adhesions from previous surgery. The trapped bowel has lost its blood supply.
