Description

<jats:p><jats:italic>Background and Aim</jats:italic>. The clinical outcomes of endoscopic submucosal dissection (ESD) for gastric tube cancer (GTC) after esophagectomy remain unclear. The aim of this study was to evaluate the clinical outcomes and safety of ESD for GTC. <jats:italic>Patients and Methods</jats:italic>. Twenty GTC lesions in 18 consecutive patients who underwent ESD between February 2008 and June 2018 were included in this retrospective study. The endpoints were the treatment outcomes of ESD (i.e., <jats:italic>en bloc</jats:italic> resection rate, complete <jats:italic>en bloc</jats:italic> resection rate, and curative resection rate), the adverse events following ESD, and the long-term outcomes. <jats:italic>Results</jats:italic>. The <jats:italic>en bloc</jats:italic> resection rate was 100%, while the complete <jats:italic>en bloc</jats:italic> resection rate and curative resection rate were 80% each. Adverse events were observed in 16.7% (3/18) of patients: one postoperative bleeding, 1 intraoperative perforation that required emergency surgery, and 1 pyothorax that required chest drainage. The 1-, 3-, and 5-year overall survival rates were 100%, 70.9%, and 70.9%, respectively. Although local recurrence was detected in 1 case of noncurative resection, no GTC- or ESD-related deaths were observed. <jats:italic>Conclusion</jats:italic>. ESD for GTC was feasible and acceptable to enable <jats:italic>en bloc</jats:italic> resection and to prevent cancer death. However, ESD for GTC should be performed more carefully than common gastric ESD because serious adverse events specific to the gastric tube may occur.</jats:p>
