Comparison of Endoscopy and Esophagram for the Routine Evaluation of Anastomosis After McKeown Esophagectomy

This retrospective cohort study reviewed patients who underwent McKeown esophagectomy. All patients routinely underwent either endoscopy or esophagram for the evaluation of anastomosis on postoperative day 7. The initiation of oral intake depended on the status of anastomosis according to the assessment result of endoscopy or esophagram. All patients were followed up for six months after the assessment of anastomosis.
