A restorative procedure currently used is construction of a neorectum using descending colon referred to as a colonic pouch. Studies have shown that the colonic pouch-anal anastomosis provides better functional outcomes than a straight coloanal anastomosis (Dehni et al., 1998; Joo et al., 1998).
In this procedure, the diseased rectum and appropriate tissues are removed and the colonic pouch is constructed in the shape of a "J" using 6 to 10 centimeters of colon.
