[CT typing and surgical approach for adenocarcinoma of the esophagogastric junction].

Objective: To investigate the feasibility, safety and efficacy of preoperative CT in the classification of adenocarcinoma of the esophagogastric junction. Methods: A total of 517 consecutive patients from May 2012 to June 2016 with esophagogastric junction carcinoma in the department of general surgery of Henan Cancer Hospital was retrospectively analyzed, according to the clinical pathological data of three type four layer method and statistics of various types of surgery in patients with preoperative enhanced CT. Results: 517 patients were successfully received surgery, including 152 cases of type Ⅰ(131 cases of complete abdominal surgery, 21 cases of abdominal incision diaphragm in thoracic surgery), 239 cases of type Ⅱ (177 cases of complete abdominal surgery, 62 cases of abdominal incision diaphragm in thoracic surgery), Ⅲ/Ⅳ type choice of chest abdominal surgery in 126 cases. The operation time was (102±17) min, the amount of hemorrhage was (136±18) ml, the dominant anastomotic fistula happened in 16 cases, 5 cases of pancreatic fistula, 7 cases of intestinal obstruction, anastomotic stenosis in 3 cases, thoracic and abdominal sensation in 12 cases, all the complications were cured by conservative treatment. The average value of esophageal resection margin was(5.1±0.6)cm, 2 cases with positive residual tumor margin and average length of stay was (8.9±1.6)d. Conclusion: Using preoperative enhanced CT in the adenocarcinoma of the esophagogastric junction to choose surgical approach can ensure the safety margin. What's more, unnecessary thoracotomy is reduced which is expected to be a new classification method for the operation of esophagogastric junction cancer.
