[Use of gastric pH-metry for peroperative evaluation of the completeness of vagotomy].

In 124 patients subjected to various types of vagotomy its completeness was tested peroperatively with Grassi test and intrastomach pH-metry. The results were compared with the Hollander test findings in 112 postoperative cases. It has been ascertained tat the peroperative pH-metry does not allow for judging on the completeness of vagotomy. The postoperative pH-metry tests show only the ability of the stomach mucous membrane to produce hydrochloric acid in response to the maximal histamine stimulation, which can be used for total evaluation of the effectiveness of the operation.
