1 cases suffering from carcinoma of rectum and have underwent excisionaloperations through incisions in the abdomen and the preanal perineum or posteri-or vaginal wall are reported. Follow-up at 6 months to 3 years show that theirdefecation function was fairly satisfactory. The operation was carried out firstlyby making two incisions, one in the abdomen, and the other in the preanal per-ineum for males or in the posterior vaginal wall for females, secondly , by takingout the free rectum with the tumour and removing it; finally by end-to-end anas-tomosis and placing the rectum back into the pelvic cavity.

Its approach is more direct and the trauma is smaller ; andit has less chance of leading to complications. This technique is not limited bythe obesity or width of the pelvic cavity of the patient.
