[Effectiveness of external drainage of the common bile duct]. / Otsenka éffektivnosti naruzhnogo drenirovaniia obshchego zhelchnogo protoka.

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.

Specific electrical conductance (SEC) of the hepatic bile in 94 patients with cholelithiasis and concomitant pancreatitis was increased (p < 0.001) and depended on the degree of cholestasis and the morpho-functional state of the liver. The value of SEC of the intraoperative bile higher than 193 S/m is taken for a criterion of the diagnostics of biliary pancreatitis. The electrical conductance of urine during the first 4 days of observation decreased in patients with acute pancreatitis (p < 0.05), impaired carbohydrate metabolism and concomitant renal dysfunction. The value of SEC of urine lower than 238 S/m corresponds to acute pancreatitis. The investigation of physico-chemical indices of biological liquids in patients with a pathology of the pancreato-biliary system allows to objectively control the course of the disease and to correct the treatment methods.

The electric conductivity of the hepatic bile received during and 24 hours after surgery from the drainage introduced into the common hepatic duct was studied in 94 patients with cholelithiasis. It is demonstrated that conductivity increases in cholestasis, inflammatory process in the biliary tract and depends on the hepatic morphofunctional status. The specific electric conductivity of intraoperative bile that is more than 192 S/m is considered to be criteria for the diagnosis of cholangitis. The electric conductivity of urine before and in first 4 days after surgery decreases in inflammation of the biliary tract and depends on the degree of concomitant renal dysfunction and electrolyte disturbances. There was a decrease in the conductivity of bile and urine in all studied groups. Detection of biophysical parameters of biological fluids may objectively control the postoperative period and correct treatment policy.
