S.info@eco-vector.com150819624341041050811202108112021Copyright © 2021, Eco-Vector2021<p>The choice of the topic of the collection is due to the fact that in the Udmurt Autonomous Soviet Socialist Republic and especially in Izhevsk, biliary tract diseases constitute a kind of regional pathology, since, according to both the clinics of the Izhevsk Medical Institute and regional hospitals, the number of patients with biliary tract diseases is 12-13% of all diseases of internal organs. This allowed the participants of the peer-reviewed collection to collect and summarize a large clinical material. To a certain extent, this collection repeats, only in an expanded form, the collection published in 195G by the Izhevsk Medical Institute under the title "Hepatocholecystitis and Cholecystohepatitis". Now everything is presented much more fully, and the number of clinical observations is much larger.</p>Kazan Medical archiveКазанский медицинский архив
