Effects of esophagogastric intramural anastomosis on the prevention of reflux esophagitis / 中华消化外科杂志

ABSTRACT

Objective To investigate the effects of esophagogastric intramural anastomosis on preventing reflux esophagitis by restoring the cardiac function after esophagectomy.Methods The clinical data of 66 esophagem or cardiac cancer patients(test group)who received esophagogastrie intramural anastomosis at Second Affiliated Hospital of Xi'an Jiaotong University from January 2002 to October 2008 were retrospectively analyzed.Sixty-five patients who received stapled anastomosis during the same period were in control group.Postoperative conditions of patients in the 2 groups were compared by chi-square test and t test.Results (1)Reflux conditionthere were 3 patients with degree I and 63 without reflux in test group,and 23 with degree Ⅰ,19 with degree Ⅱ,7 with degree Ⅲ and 16 without reflux in control group.There was a significant difference between the 2 groups(X~2=137.3,P<0.05);(2)results of barium meal fluoroscopy12 patients in test group and 41 patients in control group had barium reflux,with significant difference between the 2 groups(X~2=27.4,P<0.05);(3)results of gastroscopy9 patients in test group and 46 patients in control group had morphological changes of mucosa,with significant difference between the 2 groups(X~2=43.5,P<0.05);(4)esophageal sphincter pressurethe pressure of lower esophageal sphincter was(3.4±0.8)kPa in test group and(2.5±0.6)kPa in control group,and the pressure of upper esophageal sphincter wag(7.4±1.7)kPa in test group and(4.2±0.8)kPa in control group.There was a significant difference in esophageal sphincter pressure between the 2 groups(t=4.98,11.59,P<0.05).Conclusion Esophagogastric intramural anastomosis can partly restore the cardiac function and prevent reflux esophagitis effectively.
