title: Clinical characteristics and management of gastric tube cancer with endoscopic submucosal dissection.
abstract: OBJECTIVE
  To identify the characteristics of gastric tube cancer (GTC) and the complications associated with endoscopic submucosal dissection (ESD) for GTC.
  
  
  METHODS
  Between 2007 and 2012, 11 individuals with early gastric cancer in the reconstructed gastric tube after esophagectomy who underwent ESD in this hospital were studied. The characteristics of GTC were identified, and the complications of ESD for GTC were analyzed at three phases: preoperative, intraoperative, and postoperative.
  
  
  RESULTS
  A total of 11 consecutive patients with 11 GTCs were selected for this study. All cases underwent en bloc resections by ESD. The median procedure time was 142 min. The average GTC diameter was 26.1 mm, and the average size of the resected lesions was 45.5 mm. The histopathological diagnosis in all cases was a differentiated adenocarcinoma. In the preoperative phase, anastomotic strictures (5/11, 45%) and food residues (4/11, 36.4%) in the gastric tube were the main complications. In the intraoperative phase, bleeding was observed in 5 cases (45%). The postoperative complications observed were delayed bleeding in 2 cases (18.2%) and stenosis in one case (9.1%). The case with stenosis was successfully treated using endoscopic balloon dilatation.
  
  
  CONCLUSIONS
  Minor complications were frequently observed. However, all GTCs underwent en bloc resection with ESD without any serious complications. ESD is considered a useful treatment for GTC.
