Abstract

Purpose: Controversy exists as to whether a high or low tie ligation of the inferior mesenteric artery (IMA) is the preferred technique in surgeries of the left colon and rectum. This study aims to contribute to the discussion as to which is the more beneficial technique by investigating the neurovasculature at each site.

Methods: Ten embalmed cadaveric donors underwent division of the inferior mesenteric artery at the level of the low tie. The artery was subsequently ligated at the root to render a section of tissue for histological analysis of the proximal (high tie), mid and distal (low tie) segments.

Results: Ganglia observed in the proximal end of seven specimens in the sample imply that there would be disruption to the
innervation in a high tie procedure.

Conclusion: This study suggests that a high tie should be avoided if the low tie is oncologically viable.
