[State of the valvular function of the cardia in patients with duodenal ulcer before and after vagotomy and methods of its correction].

The authors studied the valvular function of the cardia in 714 patients who were kept under regular medical observation and in 138 patients who had been operated on for duodenal ulcer. Changes were found in the cardia of 9.4% of patients who underwent regular medical examination and in 17% of these subjected to operation. The valvular function of the cardia was impaired after vagotomy in all cases. Fundoesophagocrurorhaphy is the best method for correction of cardiac dysfunction.
