Objective：To appraise the postoperative anti-reflux function of vertical esophagogastic valve-plasty anastomosis for cardiac cancer.
Methods：Forty patients with cardiac cancer were randomly divided into study group and surgery control group, with 20 patients in each group.The study group underwent vertical esopagogastric valve-plasty anastomosis, while the surgery control group underwent conventional esophagogastrostomy. Ten healthy volunteers were recruited as normal control group. A 24-hour esophageal pH monitoring and endoscopy check-up was carried out in all experimental subjects at 90 days postoperatively.
Results：All of the pH monitoring indexes in study and surgery control groups were higher than those in normal control group (P＜0.05), and those in surgery control group were higher than those in study group (P＜0.05), and the degree of gastro-esophageal reflux and histological mucosal inflammation in study and surgery control groups were higher than those in normal control group (P＜0.05), while those in surgery control group were higher than those in study group (P＜0.05).
Conclusions：The operative type of vertical esophagogastric valve-plasty anastomosis has some reflux phenomenon, but it has marked antireflux effect compared to the traditional operation.
