[Clinical epidemiological research of antigastroesophageal reflux after cardiac plasty by anastomosis of esophageal mucosa and gastric wall].

A new operative method was designed for preventing gastroesophageal reflux after esophageal and cardiac cancer operation. From April, 1994 to December, 1995, sixty-one patients after resection of esophageal and cardiac cancer were randomly divided into two groups: experimental group with 34 patients and control group with the others. All patients were observed, monitored and followed up. It was found that no case in the experimental group showed symptoms of gastroesophageal reflux or marked reflux by esophagoscopy and barium meal examination. 10 patients (37%) in the control group had the symptoms of heartburn and regurgitation and inflammation and obvious gastroesphageal reflux were observed under esophagoscopy and barium meal examination. The pH values of anastomotic ostium were 7.0249 +/- 0.9996 and 4.6667 +/- 2.4573 in the experimental and control groups, respectively. Significant difference (P < 0.01) was observed between two groups with t test. The results showed that the advancement of operative method plays a key rolein prevention of gastroesophageal reflux.
