[A case of gastric cancer developed in the gastric tube 11 years after subtotal esophagectomy for esophageal cancer].

A case of adenocarcinoma developed in the reconstructed gastric tube after esophagectomy was reported. The patient was 66 years old man and he had received subtotal esophagectomy for the carcinoma of the esophagus 11 years previously. The follow-up examination of upper GI series revealed an ulcerative lesion in the lower part of the gastric tube and endoscopic biopsy showed adenocarcinoma. The partial resection of the lower gastric tube with mediansternotomy was performed because of limiting the invasion of the carcinoma. Pathological examination showed that poorly differentiated adenocarcinoma with signet ring cells had invaded muscularis propria. The postoperative course was uneventful and he is well without any recurrence 6 months after the operation. A double carcinoma, such as esophageal cancer concomitant gastric cancer is not rare, but a carcinoma of the gastric tube which was substituted for the esophagus is rare. Recently, the incidence of carcinoma of the gastric tube is increasing due to the increasingly long-term survival rate of patients who had esophageal carcinoma. In order to ensure the early detection of a second carcinoma which can minimalize damage from curative resections, follow up examinations should be conducted with the utmost diligence.
