Abstract    Double tract reconstruction is an ideal way of digestive tract reconstruction after proximal gastrectomy, It allows food to enter the distal digestive tract through two channels, which is beneficial to nutrient absorption and gastrointestinal hormone balance. It avoids the high incidence of reflux esophagitis after esophagogastrostomy. The surgical technique of double tract reconstruction is easier than the double flap technique and the requirement of residual stomach volume is lower double tract reconstruction can better guarantee the postoperative quality of life. However, the comparison of its effect on postoperative nutritional status with other anastomotic methods, as well as the efficiency and long-term effectiveness of double tract reconstruction remain to be evaluated by large-sample prospective clinical studies.

Key words: gastric cancer, proximal gastrectomy, double tract reconstruction
