Currently, reconstruction after esophagectomy is mainly performed using the stomach, and there is very little information on reconstruction using the colon and small intestine.

Therefore, this study aims to collect information on patients who underwent reconstruction using conduits other than the stomach, analyze the surgical performance, find clinical improvements, and build a foundation for future clinical quality improvement.
