[The lower esophageal sphincter after sclerosing of varices]

Fiberendoscopic paravasal sclerotherapy of esophageal varices with Polidocanol at concentration of 1%, is a palliative therapy of a serious sickness. Due to the location of esophageal varices, paravasal sclerotherapy with all its alteration of the esophageal wall takes place in the lower third with its lower sphincter. Twenty middle-aged patients, both sex, with esophageal varices (stadium II-IV due to Paquet) underwent clinical, endoscopic and esophagomanometric control after completion of sclerotherapy. By reaching the therapeutic goal--the subepithelial layers--no pathologic change of the motility of the esophagus has been seen.
