Objective To explore the value of dual-channel anastomosis of residual stomach and jejunum in radical resection of the upper gastric cancer. Methods Forty patients with upper gastric cancer had undergone proximal gastrectomy and dualchannel digestive tract reconstruction, including esophagus-jejunum side to side anastomosis, residual stomachjejunum anastomosis, and jejunum-jejunum anastomosis. Results The cutting margin away from tumor in all the cases was more than 5 cm and no carcinoma residual. The number of lymph nodes dissection was 21±6, reaching the requirement of D2 radical surgery. There was no case appearing complications such as anastomotic leakage, obstruction or bleeding. Barium meal examination after operation showed that most of barium was directly into the jejunum, the remaining went through the duodenum into the jejunum without gastroesophageal reflux. Followed up 6-30 months with average 18 months, there were no visible reflux esophagitis in all the cases, and only 1 case appeared minor dumping syndrome. The hemoglobin increased and the quality of life was satisfactory after operation. Conclusions In regard to dual-channel anastomosis of residual stomach and jejunum, resection range is reasonable, dissection scope accords with the protocol and residual stomach has a certain pouch effect. The anastomosis has a favorable prevention from reflux esophagitis and dumping syndrome and retains the duodenum pathway, so that improves the quality of patients’ life and is a relatively ideal digestive tract reconstruction.
