RESUMO
The main target of our investigations was the development of antireflux, bilio-cholecysto (cystico) enteral anastomosis method for the surgical treatment of extrahepatic biliary duct obstruction. We were using the cholecystic duct spiral valve (Lutkens valve, Haister valve) as the antireflux structure. In this case the bile drains into the biliary cyst not through the cholecystic duct but through the extrahepatic biliary duct - the bilio-cholecystic anastomosis. Such an interposition of cholecystic and spiral valves promotes inhibition of chemical reflux between extrahepatic ducts and gastrointestinal tract, from digestive tract into the cholecystic and intrahepatic biliary tracts. Method developed and tested by us involves creation of blio-cholecystic (cystico) entero anastomosis, namely creation of biliary duct-cholecystic (cystico)-duodenoanastomosis. 3 successful experimental operations have been performed using the above presented approach. Sutures were taken of on the seventh day, animals were housed under investigations for 10-14 days, faecal masses had normal appearance.
