Long-term Prognosis of Ulcerative Colitis and its Temporal Change Between 1977 and 2013: A Hospital-based Cohort Study from Korea

Abstract

Thiopurines and anti-TNF agents are used increasingly more frequently and earlier, while the colectomy rate has decreased over the last 30 years in Korean patients with UC. Korean UC patients may have a better clinical course than Western cases, as indicated by a lower colectomy rate.
