[About the so-called ischemic-ulcerative innerwall lesion of the bowels proximal to intestinal stenoses (author's...

The ischemic ulceration resp. the ischemic necrosis of the intestine's internal wall located proximal to an obstruction is a rare complication. At present this diagnosis is established by the radiologist alone. The knowledge of this disease--which is at the time being abscure in its origin--is of great importance to the surgeon, who has to try to resect both, the obstructes and the ischemic-ulcerative regions, in order to avoid insufficiency of the anastomosis postoperatively. The oral border of the alteration can be determined by a frozen section during the operation. In this connection the fatal complications of total necrosis of the large and small intestines resp. is demonstrated for the first time.
