Modified anoabdominal rectal resection and colonic J-pouch anal anastomosis for lower rectal carcinoma: preliminary report.

Abstract

Our results suggest that the lower half of the IAS has a more important role than the upper half in the control of defecation. Total resection of the IAS did not sacrifice continence, but preservation of at least the lower IAS resulted in a better quality of life. Careful patient selection is needed when considering the use of these procedures for tumors in the lowest part of the rectum.
