Effect of left colonic artery preservation on perfusion at the anastomosis in rectal cancer surgery evaluated with intraoperative ultrasound.

ABSTRACT:

Purpose

Intraoperative ultrasound was used to assess the flow velocity in the marginal vessel arch adjacent to the anastomosis, critical for evaluating the anastomotic blood supply. This technique also enabled us to investigate the potential effects of preserving the left colonic artery on the perfusion of the anastomosis.

Methods

This prospective study included 40 rectal cancer patients who underwent laparoscopic anterior resection between January 2021 and January 2023. The length of the inferior mesenteric artery (IMA) was measured from its origin to the first branch, and the diameters of the mesenteric vessel IMA, left colonic artery (LCA), and marginal mesenteric artery (MMA) were recorded. Blood flow velocity and Doppler ultrasound waveforms of the MMA near the anastomo
