A technique for endoscopic balloon dilatation of pyloric stenoses

A technique facilitating the endoscopic dilatation of pyloric stenoses due to peptic ulcer disease is described. By means of a Dormia basket placed in the 3rd part of the duodenum a guide wire is obtained with the aid of which the balloon catheter can be positioned. Four patients thus treated are described. Short-term follow-up has been uneventful.
