[Colo-anal intussusception of the adult. A new case (author's transl)]

Report on a case of intestinal obstruction due to a sigmoido-rectal and afterwards anal intussusception of a malignant tumor : review of the literature. Colo-anal intussusception remain very rare as, since Lataste in 1975 related six cases, this one is unique. On the contrary seven new cases of colo-rectal intussusception have been reported. Diagnosis can be difficult. The variability of the mass revealed by successive examination and the intussusception pictures sometime provided by the barium enema may give the correct direction. In this case, treatment consists in the perineal resection of the sigmoid intussusception and its causal tumor followed by an end to end primary anastomosis with an iliac colostomy. This treatment seems to be more suitable for old and deficient people where carcinologic problem is not of first importance.
