[Functional results of laparoscopic antireflux surgery and causes of postoperative dysphagia]
Abstract:
Results of functional examination of 176 patients with gastroesophageal reflux disease are presented. 94 patients were were followed up from 1 month to 4 years after laparoscopic antireflux operation (82--by Nissen and Nissen--Rossetty, 6--by Dor, 6--by Toupet). After Nissen operation the pressure in the region of lower esophageal sphincter (LES) increased more than after partial fundoplication and remained the same during 4 years of follow-up (p < 0.05). Postoperative dysphagia in the majority of cases was associated with excessive increase of pressure and length of LES region, decrease of it capacity to relaxation during swallowing (p < 0.05). 360 degrees-fundoplication can not be recommended only in complete loss of contractile capacity of the esophagus.
