[Colo-anal invaginations in adults].
Colo-anal intussusception is exceptional, there are only 6 published cases including ours, intussusception of the colon into the rectum is rare. It raises numerous diagnostic and surgical problems. The cause is always a tumour, usually malignant. The diagnosis is easy in the case of colo-anal intussusception, in which one may see the tumour and determine its nature. It is sometimes difficult in the case of colo-rectal intussusception, hence the interest of sigmoidoscopy and biopsy of the tumour. Surgical treatment includes simple reduction in the case of colo-rectal intussusception. On the other hand, in the case of colo-anal intussusception, one should first reduce the condition, otherwise it is very difficult to remove the tumour, but there is very frequently necrosis of the prolapsed segment, which may require removal in two stages, limited low resection of the necrotic segment and high removab after reduction. This operation is more easily carried out by two surgical teams operating simultaneously.
