New technique for pouch-anal reconstruction after total mesorectal excision.
OBJECTIVE
Surgical options in metachronous or recurrent rectal cancer after anterior or low anterior resection are limited and frequently result in abdominoperineal rectal extirpation sacrificing the sphincter or in straight coloanal reconstruction. Decreased capacity and distensibility in straight coloanal reconstruction after proctectomy correlate well with increased daily stool frequency, urgency, and incontinence. A new technique for coloanal pouch reconstruction using the ileocecal segment is proposed.


METHODS
A pedunculated ileocecal segment was rotated 180 degrees counterclockwise and placed between the sigmoid colon and anal canal. Ileal end of the pouch was then anastomosed end-to-end with the transected sigmoid colon and proximal end of the ileum with distal end of the ascending colon. Functional results and defecation quality of a 67-year-old woman are described 6 and 12 months after ileocolonic interposition pouch replacing the tumor-bearing rectum.


RESULTS
Twelve months postoperatively, the patient is free of disease with an excellent defecation quality, has full anal continence without soiling, is having two solid stools in 24 hours. Functional control revealed normal anal sphincter pressure and large rectal capacity and compliance. Neither outlet obstruction nor incomplete evacuation have been observed.


CONCLUSIONS
The ileocecal interposition pouch (cecum pouch) represents an alternative technique for coloanal reconstruction in low rectal cancer, recurrent rectal cancer, or metachronous low rectal cancer with intact sphincter function. This new method presents some attractive features compared with techniques presently in use.
