[The reflux-esophagitis in patients with duodenal ulcer, complicated by pyloroduodenal stenosis].

The function of esophago-gastric junction is studied in 147 patients with ulcer pyloroduodenal stenosis before and after the selective proximal vagotomy (SPV) procedure. The frequency of reflux-esophagitis was 71.9%. It is determined that reflux develops due to gastric evacuatory disorders, reduction of lower esophageal sphincter tone and contraction of abdominal part of esophagus. Reflux-esophagitis develops as the consequence of aggressive gastric juices action on the esophageal mucosa. Authors reconstruct the esophageal sphincter mechanism by performing the modified fundoplication and fundoesophagocruropexy.
