Abstract. Functional state of the liver after external drainage of bile ducts in patients with a high level of obstructive jaundice. Kutovyi O.B., Balyk D.V., Kysilevskyi D.O. The results of the examination and treatment of 67 patients with a high level of obstructive jaundice were analyzed. Diagnosis of obstructive jaundice syndrome was based on the data of anamnesis, complaints, physical, laboratory and instrumental research methods. Among the latter we performed ultrasound investigation (USI) of abdominal organs and bile ducts as a screening method, fibrogastroduodenoscopy (FGDS), computed tomography(CT), magnetic resonance cholangiopancreatography (MRCPG) was carried out if necessary. The cause of a high level of obstructive jaundice: pancreatic head cancer - 27 (40.3%); choledocholithiasis - 21 (31.3%); Klatskin tumour - 5 (7.5%); cancer of the large duodenal papilla - 4 (6.0%); chronic pseudotumor pancreatitis - 4 (6.0%); choledoch cancer - 3 (4.5%); choledochal stricture - 3 (4.5%). The first stage of treatment started from the implementation ofpercutaneous and hepatic external drainage of the bile ducts under ultrasound control. The functional state of the liver was evaluated according to the level of total bilirubin and its fractions, aspartate aminotransferase (AST), alanine aminotransferase (ALT) and alkaline phosphatase (ALP). The researches were performed at the admission ofpatients to the clinic and on day 1, 3 and 7 after external drainage of the bile ducts. Patients were divided into 2 groups, depending on the bile flow rate on the first day after decompression of the biliary tract. It was concluded that the degree of hepatitis in the early period after the performed procedure is directly associated with the bile flow rate during the first day after external drainage of the bile ducts.

Problems of timely diagnosis and effective treatment of pancreatic biliary diseases, which are complicated by the development of the high level of obstructive jaundice presently remain relevant and in the most cases they are not solved [5, 9]. Nowdays a lot of authors tend to the two-stage tactics for treating this pathology. The results of treatment of high level of obstructive jaundice depend on the prescription hyperbilirubinemia duration, the level and causes of bile duct obturation[3, 4, 10]. Surgical interventions which are performed in the first stage, at the height of jaundice, are directed to the decompression of the biliary tract and the elimination of jaundice [1, 2, 6]. At the same time, presently there are no clear notions about liver functions after external drainage of bile ducts on the background of the high level of obstructive jaundice and the prevention of liver failure, as a consequence of the rapid decompression of the biliary tract syndrome [8, 11].
The purpose of the study was to estimate the functional status of the liver in patients with the high level of obstructive jaundice depending on poor bile flow (debit) on the first day after external drainage of the biliary tracts.
MATERIALS AND METHODS OF RESEARCH
From the general group of patients with a high level of obstructive jaundice, who were on treatment in I.I. Mechnikov Regional Clinical Hospital in the city Dnipro, 67 patients aged 45 to 77 years were selected. Among them there were 38 (56.7%) women and 29 (43.3%) men. The average age of the patients was 64.4±12.1 years. The criterion for exclusion were viral hepatitis, portal hypertension, concomitant cardiac pathology and the age over 80 years.
The causes of the high level of obstructive jaundice were: pancreatic head cancer - 27 (40.3%); choledocholithiasis - 21 (31.3%); Klatskin tumour -5 (7.5%); cancer of the large duodenal papilla -4 (6.0%); chronic pseudotumorosis pancreatitis -4 (6.0%); choledoch cancer - 4.3% (95% CI 1.86.1); stricture of choledochus - 3 (4.5%).
Diagnosis of mechanical jaundice syndrome was based on the data of anamnesis, complaints and physical, laboratory and instrumental research methods. Patients underwent ultrasound investigation (USI) of the abdominal organs and bile ducts as a scrining method, fibrogastroduodenoscopy (FGDS), computed tomography (CT), magnetic resonance cholangiopancreatography (MRCPG), if necessary. Assessment of the functional state of the liver was performed according to the level of total bilirubin in the serum of blood and its fractions, aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (ALP).
The first stage of treatment started from drainage of the bile duct under ultrasound control. Drainages were presented by Fr10 tubes of 9 and 8 diameters. In case of cholangitis antibacterial drugs were prescribed. The functional state of the liver was examined on admission, on the first, third and seventh days after external drainage of the biliary tracts.
Patients were divided into two groups, depending on the bile flow on the first day after drainage of the biliary tract. Group I (n=33) - patients with the total bile amount of up to 300 ml, group II - (n=34 -patients with the total bile amount of more than 300 ml). According to age and the level of indicators of functional activity of the liver during the investigation before drainage, the patients of both groups were comparable (p>0.05).
The statistical processing of the data was carried out using Statistica v.6.1 statistical software application (Statsoft Inc., USA, license number AJAR909E415822FA). The methods of descriptive and analytical biostatistics were used, in particular, the verification of the distribution of quantitative attributes for compliance with the normal law according to the criterion of Shapiro-Wilka. The critical level of statistical significance in checking all hypotheses was taken <5% (p<0.05) [7].
RESULTS AND DISCUSSION
When analyzing the results of external drainage of the biliary tract, it was determined that the most common complications were: bleeding into the abdominal cavity in 1 case - 1.5%; dislocation of drainage tube in 1 case - 1.5%. Violations of drainage were observed in 2 cases - 3.0% of patients.
The dynamics of the level of almost all investigated indicators of the functional state of the liver after external decompression of the biliary tract was not the same. So, after drainage of bile ducts different trend in the changes of levels of total bilirubin was observed (Fig. 1).
Patients in both groups showed a tendency to increase in the index on already the 1st day after drainage of the biliary tracts. On the third day in patients of group I the level of the total bilirubin showed a tendency to decrease. At the same time in patients of group II the level of the index increased and decreased only on the 7th day after decompression of the biliary tract. It should be noted that the rates of the total bilirubin in patients of groups I and II on the 3d and 7th day differed significantly (p<0.01).
In contrast to changes in the total blood serum bilirubin content, the level of its direct fraction during the examination tended to decrease, approximately, equally in patients of both groups (Fig. 2 ).

МЕДИЧН1ПЕРСПЕКТИВИ / MEDICNIPERSPEKTIVI
bile in the first day after decompression of the biliary tract on the third stage of the study was accompanied by hyperenzymemia, which indicates the progression of hepatocyte cytolysis, and an increase in bilirubin levels due to indirect fraction in the liver. Thus, the degree of functional state of the liver after external decompression of the biliary tract directly depended on the daily amount of bile.
The results of the research show the dependence of the main indicators of the functional state of the liver on the loss of bile during the first day after external drainage of the biliary tract in patients with high level of mechanical jaundice. However, the evaluation of the significance of these changes in terms of the final results of treatment requires
further analysis of the presented material. If the obtained data are really important, it is possible that it would be rational to artificially prevent the loss of a large amount of bile in the appropriate period after the drainage of the hepatic ducts or not to drain them at all, and to perform conditionally radical surgery at the height of jaundice.
CONCLUSIONS
Thus, bile flow (debit) on the first day after external drainage of biliary tract more than 300.0 ml, is a prerequisite for the development of hepatargia in the early period after biliary decompression.
The authors declare that there is no conflict of interest.
