The study hypothesized that a narrow gastric conduit(less than 3cm in width) would minimize anastomotic leakage following minimally invasive esophagectomy. Therefore we raise this random-controlled research, and investigate the leakage ratio from different widths of gastric conduit formed during the operation.

Patients underwent minimally invasive esophagectomy in Zhongshan Hospital of Fudan University will be enrolled and be assigned to wide or narrow gastric conduit group randomly. Intra-operative blood supply and vascular SaO2 will be observed during the operation, and the rate of anastomotic leakage, together with its clinical details will be recorded in the two groups.

Inclusion Criteria:

1. Patients underwent minimally invasive esophagectomy(three-hole procedure)
2. Clinical Staged T1-3N0M0 esophageal cancer patients or: patients who were restaged as T1-3N0M0 esophageal cancer after neo-adjuvant therapy

Exclusion Criteria:

1. With previous cancer history
2. Severe Co-morbidity
