The investigators improved the hybrid everted esophagogastrostomy and expected to prevent the incidence of anastomotic stricture. The purpose of this study is to determine the clinical value of this kind of operation type, and analyzes the clinicopathological factors causing the postoperative complications.

Primary Outcome Measures:
  • the incidence of anastomotic stricture [ Time Frame: three months ]
    the anastomotic stricture is defined as the diameter of the anastomotic orifice <= 0.8 cm on esophagogram

Secondary Outcome Measures:
  • The grades of dysphagia [ Time Frame: three months ]

    0:No dysphagia on solid diet

    1. dysphagia on solid diet
    2. dyspahgia on semi-solid diet
    3. dysphagia on fluid diet
    4. dysphagia with water swallowing

  • the grades of acid regurgitation [ Time Frame: three months ]

    0:no reflux on semi-supine position

    1. postprandial reflux on semi-supine position
    2. reflux with empty stomatch on semi-supine position
    3. postprandial reflux on upright position
    4. reflux with empty stomach on upright positino

  • the clinicopathological parameters in relation to postoperative complications [ Time Frame: three months ]

Detailed Description:
This randomized clinical trial compared a hybrid everted esophagogastric anastomosis with conventional hand-sewn or stapled esophagogastrostomy for prevention of anastomotic stricture. The patients were completely randomized to receive either a hybrid everted esophagogastric anastomosis (HE group), or the conventional hand-sewn (HS group), or a stapled (SA group) anastomosis, after the removal of esophageal tumor. The primary outcome measured the incidence of anastomotic stricture at 3 months after the operation (defined as the diameter of the anastomotic orifice <= 0.8 cm on esophagogram), analyzed by intention-to-treat.
