title: [Parallel and spiral anomalies of the cystic duct].
abstract: Parallel and spiral anomalies of the cystic duct, that are found in every fourth--fifth patient, are of certain importance for the practical surgery. When at cholecystectomy a hidden long stump of the anomalous cystic duct is left it might result in the same complications which are described when a long external stump of the cystic duct is left. Analysing anatomical peculiarities and positions of the anomalous cystic ducts as regards to the common hepatic duct, found in 51 patients at operations, it was revealed: the length of the anomalous course of the cystic duct in 13 patients was 20-25 mm, in 30 patients--from 30 up to 50 mm, in 10 patients--60--75 mm. The parallel anomalies were revealed in 18 patients, the spiral ones--in 23 patients. In the latter cases the cystic duct adjoined the anterior, posterior and even the medial walls of the common hepatic duct and had not only an oblique-spiral course, but a transversal one, too. For these 6 variants certain working terms were suggested. In 10 patients mixed anomalies of the cystic ducts were found with its parallel and spiral disposition. Four types of the mixed anomalies were distinguished and they were also given certain working terms. The terms suggested for the variants of the cystic ducts could be helpful for medical documentation and for exact statistics of these anomalies.
