Introduction: There are several methods at the case of mechanical jaundice, e.g. percutan transhepatic or endoscopic retrograde drainage, stent implantation, or operative choledocho-duodenostomy. As complications cholangitis and occlusion of the stent are very frequent, and the traditional surgical procedure needs narcosis. Our new approach is a minimal invasive technique to create bilio-enteric anastomosis.

Method: The technical feasibility of the procedure was made on biosynthetic model under fluoroscopy. After canulation of the intrahepatic bile ducts in a transhepatic way a 1,5 mm canule was lead into the retroduodenal common bile duct and a guide wire was lead into the bulb of the duodenum via the working channel of a gastroscope. The rare-earth magnet (NdFeBr) which was pushed into the cannula, matched to the other one which was lead on the guide wire. On living tissue the magnets create ischemic necrosis which leads to gradual anastomosis formation between the adjacent tissues.

Result: Our experiment demonstrates a successful technical application of the magnets on the porcine biosynthetic model.
