Effectiveness of external drainage of the common bile duct

: Influence of different methods of external drainage of the biliary tract on dynamics of inflammation in the biliary tracts was evaluated based on the data examination of bioimpedance, specific electric conductivity and general microbial number of bile received during surgery and from drainage of the common bile duct during 9 days after surgery in 197 patients with cholelithiasis complicated by bile outflow disturbances. It is demonstrated that each type of external drainage has own indications depending on the degree of bacterial contamination, macroscopic structure, biophysical parameters of bile, and planned treatment policy after surgery. Right fixation of the drainage tube in the common bile duct improves immediate results of surgical treatment of patients with cholelithiasis.
