THE INSERTION METHOD BY THE COMBINATION OF LONGOVERTUBE AND EXPANSION BALOON FOR ESOPHAGUS IN MALIGNANT DUODENAL STENOSIS

Abstract

This time, to get rid of stent insertion trouble in the self-expandable metallic stent (SEMS) treatment of the malignant duodenal stenosis, a new insertion method was divised. In 8 cases of malignant duodenal stenosis, the insertion method by the use of the combination of longovertube and expansion balloon for esophagus was practised. At the result of the use of this new stent insertion method, the insertion trouble experienced in the longovertube method was prevented, and moreover it is supposed to prevent of perforation at the duodenal portion. This method is surpassing in certainity and safety for stent insertion, and it is suitable to use in all cases of malignant gastrointestinal stenosis from gastric antrum to treitz without multiple malignant gastrointestinal stenosis.
