Study on esophageal motor function against reflux after esophagogastric anastomosis with mucosal valve / 中华胃肠外科杂志

ABSTRACT

<p><b>OBJECTIVE</b>To find an effective operative procedure against reflux after esophagogastric anastomosis with mucosal valve.</p><p><b>METHODS</b>Four hundred and sixty-four patients with esophageal or cardiac cancer were randomly divided into three groups according to anastomosis modes. Group A underwent esophagogastric anastomosis with mucosal valve (175 cases), group B with mechanical stapler (151 cases) and group C one layer anastomosis with handcraft suture (138 cases). The gastroesophageal reflux index (GERI) was examined by isotope,and 24 h esophageal pH was also monitored. The esophageal motor function was compared among three groups.</p><p><b>RESULTS</b>The reflux rates were 0, 33.3%, and 6.7% in group A, B, C respectively. The esophageal motor function and the 24 h esophageal pH monitoring indicated that the various indexes were approaching to the normal level in group A, but the various indexes in group B and C were significantly different from the normal values (P< 0.05).</p><p><b>CONCLUSION</b>The esophagogastric anastomosis with mucosal valve has better antireflux effect and can prevent the reflux esophagitis after esophageal or cardiac cancer eradication.</p>
