[Experimental grounds for the formation of an increased pressure zone in the area of "impaired" lower esophageal sphincter].
A method of the formation of an artificial lower esophageal sphincter (LES) with the help of superelastic threads made of a nickelide-titan alloy was developed in the experiment. An experimental model of an artificial LES was tested on cadaver organic combinations of the esophagus and stomach in ten watchdogs and ten rabbits. Tests of the esophageal passage and antireflux features of the artificial lower esophageal sphincter (LES) and assessment of morphological changes in esophageal wall layers with the emphasis on changes of the esophageal wall structure and gastroesophageal passage near the thread were made. This experiment proved that the passage in the artificial lower esophageal sphincter (LES) area is not disturbed and a zone of increased pressure is created.
