Two cases of the idiopathic rupture of normal colons have been reported and as many as 26 cases have been obtained from the medical literature. 18 cases of them were involved in sigmoid, 5 cases in rectum, and two cases in tranverse colon.
It is difficult to explain the cases of the mechanism of perforation, but there can be seen many kinds of theories on the cause of rupture. The impaction of the hard fecal mass in colon may lead to the causes of necrosis and perforation.
On the antimesenteric wall of the colon, the blood-supply is poorest. The intraabdominal pressure at evacuation may cause the perforation in the rectum.
There were 13 deathes among 28 patints, but any better improvement of perforation may give a promising perspective for the earlier recovery of the idiopathic rupture.
