Current status of IBD and surgery of Crohn's disease in Thailand

Abstract

Inflammatory bowel disease (IBD) consists of two diseases: ulcerative colitis (UC) and Crohn's disease (CD). The incidence of IBD is much higher in Western countries compared to Asian countries, especially in Thailand. The incidence of UC in Thailand is quite low and seems less aggressive than in Western countries. Over the past two decades, the evolution of UC management in Thailand has led to a reduction in hospitalization and colectomy rate. Regarding CD, the majority of patients have an inflammatory phenotype at diagnosis. Diagnosis of CD remains challenging in Thailand as the time from onset of symptoms to diagnosis is quite delayed, possibly due to unawareness and difficulty in the differential diagnosis between CD and other infectious entero-colitis such as intestinal tuberculosis. With a significant trend to early initiation of immunomodulators and biologics, the cumulative rate of surgery after diagnosis has been improved. To improve the outcomes of CD treatment in Thailand, physicians need more awareness to recognize the disease, which results in early diagnosis, prevention of long-term complications, and reduction in the rate of surgery.
