Recent improvements in the survival of patients after esophagectomy have led to an increase in the occurrence of gastric tube cancers(GTC). We retrospectively examined 7 patients who were surgically treated for GTC among 13 patients who were diagnosed between April 2004 and December 2018. Partial gastrectomy with regional lymph node dissection was performed in 6 patients while total resection of the stomach was performed only in 1 patient. Postoperative complications included 1 anastomotic leakage and 1 subcutaneous abscess. We performed subtotal gastrectomy with preservation of the upper region of the gastric tube in 3 patients. In these patients, blood flow was confirmed from the remnant esophagus to the upper region of the gastric tube using indocyanine green fluorescence imaging. The pathological stage of the treated GTCs were 4 cases of Stage ⅠA, 2 of Stage ⅠB, and 1 of Stage ⅡA. Median follow-up time and postoperative survival time were 32 months and 46.5 months, respectively. Most of our surgically treated cases were early gastric carcinomas that could be radically resected.
