[The classification of obstructive jaundice severity].

It was analyzed the results of examination and surgical treatment of 338 patients with obstructive jaundice. The patients were operated in 2004-2012 years. 148 patients had benign jaundice and 190 patients had malignancy genesis of jaundice. It was determined laboratory data (bilirubin total, protein total, prothrombin index) as well as complications of obstructive jaundice (cholangitis, renal failure, hepatic encephalopathy, gastrointestinal bleeding, sepsis) indicating to the severity of obstructive jaundice and it was taken into consideration the malignant origin of jaundice. The selected attributes were assigned marks from 1 to 3. Each complication as well as factor of malignancy was evaluated two times higher than mark of bilirubin. The grade of jaundice severity (A, B, C) was determined by combination of the marks that identified the attributes. It was analyzed the influence of prothrombin index and blood serum protein on the results of severity grade formation of obstructive jaundice with the postoperative results (lethality, complications). It was done for simplification of classification. The absence of significant differences in assessing of the severity obstructive jaundice class with and without attributes of a "total protein" and "prothrombin index". To simplify the classification and to get more reliable information about the difference of postoperative results between the grades (A, B, C) are possible by exception of total protein attributes and prothrombin index.
