Brief Summary:
To compare transhiatal / transabdominal approach with thoracoabdominal approach for Siewert II adenocarcinoma of esophagogastric junction

Condition or disease Intervention/treatment Phase
Adenocarcinoma of Esophagogastric Junction Procedure: transhiatal/transabdominal approach Procedure: thoracoabdominal approach Not Applicable

Detailed Description:

Objective: To compare the safety and clinical efficacy between transhiatal/transabdominal and thoracoabdominal approach for Siewert Ⅱ adenocarcinoma of esophagogastric junction.

Methods: A prospective, multi-center, randomized, controlled study will be performed. Patients who meet the eligibility criteria will be registered in the study and undergo radical surgery via transhiatal/transabdominal or thoracoabdominal approach. The data of preoperative, intraoperative, postoperative and follow-up will be recorded and analyzed.

The primary endpoints :3-year disease-free survival. The secondary endpoints:(1) Surgery and oncology indicators ;(2) The incidences of postoperative complications and mortality.

Primary Outcome Measures :
  1. 3-year disease-free survival [ Time Frame: 3 years after surgery ]
    Proportion of patients without tumor recurrence from surgery to the end of the 3-year follow-up

Secondary Outcome Measures :

    The proportion of patients undergoing radical resection in all surgical patients

  2. The number of lymph node dissections and the positive [ Time Frame: About 10 days after surgery ]
    The number of lymph node dissections and the positive

  3. The duration of postoperative hospitalization [ Time Frame: Within 6 months after surgery ]
    Time from end of surgery to discharge

  4. The incidences of early postoperative complications [ Time Frame: Within 30 days after surgery ]
    The incidence of postoperative complications such as pneumonia, pleural effusion, anastomotic stenosis, anastomotic leakage, duodenal stump fistula, pancreatic fistula, abdominal abscess, and deep vein thrombosis (%).

  5. The incidence of perioperative mortality [ Time Frame: Within 30 days after surgery ]
    The incidence of death due to the surgery
