[Intestinal invagination caused by submucous pedunculated lipoma of the large intestine].

A case of colo-colic invagination caused by lipoma of the splenic flexure which led to emergency operation is reported. Colon lipomas are benign neoformations of the submucosa with prevalence of the right colon and with a frequency of from 0.3% to 5.8% in the whole population depending on clinical or autoptic series. Radiological and endoscopic investigations provide orientative elements for diagnosis. The most frequent complications are bleeding and intussusception in 50% of cases. Surgical removal may be carried out, preferably segmentary resection, so as not to be forced to operate on a complication in emergency conditions.
