Inferior
Defecatory dysfunction after colon cancer resection. The role of inferior mesenteric artery tie
Background: Although oncological results for resection of colon cancer with inferior mesenteric artery (IMA) ligation at its origin (high tie) or immediately below the left colic artery (low tie) are similar, injury of the superior hypogastric plexus may be caused when the IMA is tied at its origin, thus impairing defecatory functions. Aim: The importance of IMA tie location on defecatory dysfunction in patients undergoing laparoscopic sigmoidal resection without preoperative radiation therapy was studied.
