Abstract

Background
In Mongolia 2020, there are 1,414 respiratory diseases, 1,833 gastrointestinal diseases, 1,268 cardiovascular diseases, 1,084 urogenital diseases, 598 injuries, poisonings and other external diseases per 10,000 population in our country, and compared to 2019, the leading causes of diseases are decreased by 12,685. As of 2020, there were 353 cases of acute hepatitis virus infection nationwide, which is 1.1 per 10,000 population, which is 1.1% of the total infectious diseases. Compared to last year, the number of reported cases decreased by 174 cases or 0.6 per 10,000 population.
Methods
The survey will be conducted among 155 clients who underwent liver transplant surgery between March 2011 and April 2022, based on the Organ Transplant Center of the Ulaanbaatar City Hospital, with the approval of the Ethics Committee.
Results
Regardless of the type of grafts or biliary reconstruction, the overall incidence of BC's in recipients ranges from 7.4% to 25%; leaks occur in 5%–18%, Pand strictures occur in 6%–20%.
Conclusions
Anastomosis and non-anastomosis stenosis after liver transplant surgery are affected by the duration of warm and cold ischemic time, stenosis and occlusion of the hepatic artery.
