Transsacral approach to the rectum.
While the proximal or upper third of the rectum is readily accessible through the lower abdomen, lesions of the distal rectum are difficult to reach both from abdomen and the perineum. The transsacral approach (Kraske) gives excellent exposure of the mid and lower rectum. The experience using this approach in sixteen cases for various indications which include local excision of benign tumours, segmental excision, repair of recto-vesical fistula, perineal excision of rectum and abdominal excision of rectal carcinoma and low colo-rectal anastomosis with preservation of ano rectal sphincters is reported. In some cases where wider exposure of the rectum is required, this was easily achieved by excising the last three pieces of sacrum and/or extending below by dividing the external sphincter. While incontinence is not a long term problem, attention to technical details and creation of a temporary colostomy are necessary for all cases of excision and end-to-end anastomosis to prevent leakage and septic complications. Temporary colostomy is not required for excision of part of the circumference of the rectum as in the treatment of most benign lesions.
