BILIARY-GASTROINTESTINAL FISTULA-FORMING TUBE

摘要

PROBLEM TO BE SOLVED: To provide a biliary-gastrointestinal fistula-forming tube preventing bile from being easily leaked in inserting the tube, forming a fistula wall in an early stage after placement, and being less likely to cause contraction after removal of the tube in the biliary-gastrointestinal fistula-forming tube for creating a bypass between the gallbladder or biliary tract, and the digestive tract to form the fistula for discharging the bile.;SOLUTION: The biliary-gastrointestinal fistula forming tube for creating a bypass between the gallbladder or biliary tract, and the digestive tract to form a fistula for discharging bile, comprises; a tubular body composed of a bioabsorbable material or a non-bioabsorbable material; and a porous tubular body disposed at the outside of the tubular body and composed of a bioabsorbable material.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2019,JPO&INPIT
