Clinical outcomes and radiological assessment of vascular anatomy in patients who underwent D3 left hemicolectomy.

Background: Adequate blood supply is one of the key factors for colorectal anastomosis healing. Various variants of vascular anatomy often come as a surprise to surgeons during operations.

Objectives: The aims of this study were to carry out a comparative analysis of three-dimensional-computed tomography (3D-CT) angiography data with intraoperative data and a detailed analysis of variants of the anatomy of splenic flexure.
