简要总结
In the past years, the adenocarcinoma of the esophagogastric junction (AEG) has been increasing obviously in China. It may be caused by the reason of increased body weight, alcohol consumption, gastroesophageal reflux disease and premalignant. In western countries, the 5-year rate of advanced AEG was less than 30%, it was the same in China. There was significant difference in epidemiology, pathogenic mechanism, biological characteristics and prognosis between AEG and antrum tumors, so AEG was regarded as a kind of independent disease. Up till now, the scope of lymph node dissected, the selection of operation approach, the resection range and the digestive tract reconstruction for the treatment of AEG were in dispute, especially in the reconstruction of digestive tract after operation. The purpose of this study is to investigate the efficacy and safety of the proximal gastrectomy combined with Giraffe anastomosis for early adenocarcinoma of esophagogastric junction.

In the past years, the adenocarcinoma of the esophagogastric junction (AEG) has been increasing obviously in China. It may be caused by the reason of increased body weight, alcohol consumption, gastroesophageal reflux disease and premalignant. In western countries, the 5-year rate of advanced AEG was less than 30%, it was the same in China. There was significant difference in epidemiology, pathogenic mechanism, biological characteristics and prognosis between AEG and antrum tumors, so AEG was regarded as a kind of independent disease. Up till now, the scope of lymph node dissected, the selection of operation approach, the resection range and the digestive tract reconstruction for the treatment of AEG were in dispute, especially in the reconstruction of digestive tract after operation.
The digestive tract reconstruction methods for AEG II were determined by the surgical approach. The controversy exists regarding whether reconstruction method with low esophageal reflux should be used to treat AEG patients. The gastric tube reconstruction, the antrum-preserving double-tract reconstruction and the Roux-en-Y reconstruction were the common methods. Some studies showed that the 24-h pH profile in the patients with gastric tube reconstruction was similar to the healthy person, but it may be related to the increasing incidence of gastroesophageal reflux disease in the healthy person and the anti-reflux medication used in the patients. Although the antrum-preserving double-tract reconstruction have a good function of anti-reflux, the complicated operation and too many anastomotic stomas increased the rate of postoperative happened. The common physiological mechanism of anti-reflux was caused by the lower esophageal sphincter, esophagogastric junction, His angle and so on. Therefore, in our center, we use a new reconstruction which combine the advantages of gastric tube reconstruction with rebuilding the His angle and fundus of gastric. We call it Gastric tube interposition esophagogastrostomy with reconstruction of His angle and fundus (Giraffe anastomosis).
