[The use of Grüntzig-type balloon catheters for dilatation in stenoses of the pylorus and the duodenum]

The paper is concerned with original methods of balloon dilatation with high-pressure low-profile balloon catheters of Grüntzig type of pyloric and duodenal stenoses. A new informative method of recording of this procedure and its results with computer for radiography was described. In 10 patients this method was used alone as well as in combination with sparing operation--selective proximal vagotomy. In 80% of cases a positive effect of this procedure was obtained and confirmed by clinical observation and instrumental methods. No complications were noted. Therefore this methods could be recommended for a wider clinical use.
