Abstract

Backgrounds/Aims: To understand the changing demands for hepatic resection (HR), we collected data regarding HR performed in a tertiary centre over a period of 10 years.
Methods: We carried out extensive search of institutional databases to identify HR cases performed between January 2005 and December 2014. A study cohort of 9,016 patients were divided into 5 disease categories, namely hepatocellular carcinoma (HCC), intrahepatic cholangiocarcinoma (ICC), intrahepatic duct stone disease (IHDS), colorectal cancer liver metastasis (CRLM), and uncommon/rare diseases (URD).
Results: There were 5,661 (62.8%) HCC cases, followed by 1441 (16.0%) CRLM, 942 (10.5%) ICC, 638 (7.1%) IHDS and 334 (3.7%) URD. The number of annual HR cases gradually increased from 443 in 2005 to 1,260 in 2015. Annual HCC cases also gradually increased, but the annual proportion of HCC cases fluctuated narrowly between 58.3% and 70.2%. Annual CRLM cases increased rapidly, and their proportion increased progressively from 4.7% to 20.5%. Annual ICC cases increased slowly, and their annual proportion fluctuated between 7.2% and 15.6%. Annual IHDS cases decreased slowly, and their annual proportion decreased progressively from 17.2% to 3.4%, while annual URD cases fluctuated, with annual proportions varying between 2.3% and 5.6%.
Conclusions: Annual cases of HR increased over the last 10 years in a tertiary center probably due to a center-specific centralization effect. The number of CRLM cases increased rapidly; those of HCC and ICC increased gradually, and those of IHDS declined gradually. We believe that these results reflect real changes in the types of liver disease requiring HR
