Purpose: We aimed to investigate the extent of heterogeneity in medical terminology between South and North Korea by comparing medical terms related to the colorectal system.
Methods: North Korean medical terms were collected from the sections on diseases of the small intestine and colon in a surgery textbook from North Korea, and those terms were compared with their corresponding terms in a South Korean medical terminology textbook. The terms were categorized as either identical, similar, showing disparity, or not used in South Korea.
