ABSTRACT
OBJECTIVE:
Anastomotic leakage is one of the most severe complications after esophagectomy. However, a diagnostic gold standard for anastomotic leakage has not been established yet. This retrospective cohort study aimed to evaluate the potential use of routine postoperative contrast-enhanced computed tomography findings as an early predictor of anastomotic leakage in patients who underwent esophagectomy for esophageal cancer.METHODS:
This study included 75 patients who underwent Mckeown esophagectomy, of whom 22 developed anastomotic leakage after surgery. The computed tomography findings for this patient cohort were categorized into 3 grades based on mural enhancement patterns observed at the anastomotic site. Both semiquantitative and quantitative analyses were performed, and the interobserver agreement between the 2 experienced radiologists was assessed.RESULTS:
It was found that poor enhancement in both the early and portal venous phases (grade 2) had a robust association with the occurrence of anastomotic leakage. The computed tomography enhancement ratio that is used to estimate wall degeneration and ischemia was significantly higher in patients with anastomotic leakage.CONCLUSIONS:
Routine postoperative contrast-enhanced computed tomography could be beneficial for the early detection of anastomotic leakage, even in asymptomatic patients, after esophagectomy.
