We report two cases of gastric tube carcinoma (GTC) treated with endoscopic submucosal dissection (ESD) after esophagectomy. Case 1 was a 47-year-old woman who had received esophagectomy with reconstruction of the gastric tube (GT) for esophageal squamous cell carcinoma. Sixty-seven months later, endoscopy showed a carcinoma in the lower part of the GT. The removed tumor showed a 0-IIc lesion, 10 mm in diameter, diagnosed as a signet ring cell carcinoma limited to the mucosa. Case 2 was an 83-year-old woman who simultaneously underwent lower esophagectomy for basaloid-squamous cell carcinoma of the esophagus and colectomy for ascending colon carcinoma. Sixty-one months later, endoscopy showed a carcinoma in the middle part of the GT. The tumor removed by ESD showed a 0-IIa+IIc lesion, 50 mm in diameter, diagnosed as a moderately differentiated tubular adenocarcinoma limited to the mucosa. The clinicopathologic features of 48 Japanese cases, including Cases 1 and 2, with GTC were reviewed. An extended indication of endoscopic resection for gastric carcinoma was present in 12 (25%) including Cases 1 and 2. In conclusion, ESD may be safe for GTC; however, further investigations may be necessary to confirm the safety and curative potential of ESD for GTC.
