Are there any surgical and radiological correlations to the level of ligation of the inferior mesenteric artery after sigmoidectomy for cancer?

In conclusion, the surgical and radiological correlations are low as the intraoperative estimation of the level of IMA ligation was correlated with CT findings in less than 50% of cases. No risk factors for non-correlation were identified, and there was no impact on lymphadenectomy. Overestimation of the level of ligation was the most frequent situation but did not appear to have any impact on tumor staging or on patient management in this group of patients.
