Core Tip

Core Tip: Anastomotic leakage is a serious complication following McKeown esophagectomy. In this single-center retrospective cohort study, shorter right gastroepiploic artery length measured by preoperative computed tomographic angiography was associated with a higher incidence of anastomotic leakage. A cohort-specific threshold was identified, suggesting that preoperative assessment of vascular anatomy may assist in perioperative risk stratification. These findings provide confirmatory evidence supporting the role of quantitative preoperative anatomical evaluation, while underscoring the need for prospective validation before routine clinical implementation.
