      MORPHOLOGICAL PARTICULARITIES OF HEPATIC, CISTIC AND COLEDOC CHANNELS (Astract): By dissection and the study of colangiographies on a number of 28 cases, we obtained a number of morphological peculiarities of the site and mode of formation of the hepatic, cystic and bile ducts. The right hepatic duct was formed from two branches (anterior and posterior) in 67.86% of cases, and in 32.14% of cases in three branches. In 53.57% of cases the right hepatic duct was more voluminous than the left hepatic. The left hepatic duct was formed from two branches (lateral and medial) in 78.57% of cases, in 21.43% of cases consisting of 3 branches. It is longer than the right hepatic duct, in 25% of cases being curled. In 17.86% of cases it was more voluminous than the counterpart on the right side. The common hepatic duct was formed from two hepatic ducts in 75% of cases, in 25% of cases with 3 hepatic channels. In 7,14% of cases, the hepatic duct confluence was intrahepatic, in 50% of the cases in the hepatic hilum, 1-1,5 cm from the surface of the liver, “high confluency”, and in 42,86% of the cases it was “low confluence”, near half the distance between the liver and the first part of the duodenum. The cystic duct in 82.15% of cases had a corrugated tract, of which in 7.14% of the cases it had an italic “S” trace. In 7,14% of cases it had an ascending tract, and in the remaining cases its trajectory was transverse or descending (most frequently). In 51.14% of cases, the cystic duct present, before joining the common hepatic duct, a tract associated with it (in the “rifle tube”), being attached either to the right lateral side of the common hepatic duct or to its posterior or posterolateral side, this last variant being encountered in 21.43% of cases. To the end of the cystic duct in the hepatic duct we described the following variants: high (28.57% of cases), the confluence being about 1 cm below the liver; middle, (25% of cases), halfway between the liver and the first part of the duodenum; low (43% of cases), with 3 variants: above the first part of the duodenum (32.14%), retroduodenal (10.71%), retropancreatic (7.14% of cases).
