Core Tip
Core tip: This multi-center study is the first nationwide report on the surgical outcomes of Korean ulcerative colitis (UC) patients and reflects the recent status of surgically treated Korean UC patients. The authors found that most Korean UC patients experienced early disease exacerbation or complications. Approximately 10% of UC patients had colitis-associated cancer (CAC), and UC patients with CAC had a later diagnosis, a longer disease duration, and less steroid treatment than UC patients without CAC.
