BACKGROUND: Gastric tube cancers (GTCs) are found frequently, even as the surgical outcomes of esophageal cancer improve. Diagnosing and treating early gastric tube cancer endoscopically has therefore become very important. AIMS: This study aimed to evaluate the clinical characteristics and outcomes of endoscopic resection for GTC. METHODS: We analyzed 29 patients (33 lesions) with metachronous GTC who underwent endoscopic resection from April 2005 to August 2016 and evaluated their clinical characteristics and the short-term outcomes of endoscopic resection. RESULTS: All of the cases were identified by periodic examinations. The lesions were found a median of 6.5 years after surgery (range 9 months-19 years), with six lesions found more than 10 years later. Among the total of 33 lesions, 28 resulted in curative resections (85%), and five were non-curative resections because of lymphovascular invasion, submucosal deep invasion, histological type, and size. None had received additional treatment or had a local recurrence thus far. Regarding the complications, delayed perforation occurred in a case (3%) and precordial skin burn occurred in four cases (12%). CONCLUSION: The safety and efficacy of endoscopic resection for gastric tube cancer were evaluated. Additionally, it is important to continue annual endoscopy even 5 years or more after esophageal surgery.
