Preoperative Computed Tomography Angiography in Multidisciplinary Personalized Assessment of Patient With Right-Sided Colon Cancer: Surgeon and Radiologist Point of View

Abstract

BACKGROUND: 3D-CT angiography has made it possible to reach a qualitatively new level in the determination of treatment tactics for patients with colorectal cancer. AIMS: This study aimed to analyze the clinical and radiological aspects that need to be discussed before surgery by a multidisciplinary team in patients with right-sided colon cancer. METHODS This study involved 103 patients with colorectal cancer who underwent preoperative 3D-CT angiography from 2016 to 2021 RESULTS: All patients underwent radical D3 right hemicolectomy. The median quantity of removal lymph nodes were 24.71±10.04. Anastomotic leakage was diagnosed in one patient. We have identified eight most common types of superior mesenteric artery. The ileocolic artery crossed the superior mesenteric vein on the anterior surface in 64 (62.1%) patients and on the posterior surface in 39 (37.9%). In 58 (56.3%) patients, the right colic artery was either absent or was a nonindependent branch of superior mesenteric artery. The distance from the root of the superior mesenteric artery to the root of the middle colic artery was 37.8±12.8 mm and that from the root of the middle colic artery to the root of the ileocolic artery was 29.5±15.7 mm. The trunk of Henle was above the root of the middle colic artery in 66 (64.1%) patients, at the same level with the middle colic artery in 16 (15.5%), and below the middle colic artery in 18 (17.5%) patients. CONCLUSIONS: Preoperative analysis of 3D-CT angiography is a key pattern in assessment of vascular anatomy and can potentially show the complexity of future lymphadenectomy and reduce the risk of anastomotic leakage.

“…A legtöbb hasonló jellegű vizsgálat nem tesz különbséget a jobb és a bal oldali vastagbélműtétek között, többségük retrospektív adatokra támaszkodik, vagy csak a radiológiailag detektált és a valós vascularis anatómia közötti különbségekre összpontosít [21][22][23][24][25][26].…”
