The incidence of the CD was increased significant in KKUH from 77 patients diagnosed as Crohns disease from ( ) to 42 new patients with CD within ( ) The incidence of the CD was increased significant in KKUH from 77 patients diagnosed as Crohns disease from ( ) to 42 new patients with CD within ( ) The patients had more severe disease and more colonic involvement.

Conclusion This study shows an increase in the incidence of CD in Saudi population in tertiary centre especially in the last 3 years This study shows an increase in the incidence of CD in Saudi population in tertiary centre especially in the last 3 years national data registry is needed for the true prevalence of crohns diasease in Saudi Arabia national data registry is needed for the true prevalence of crohns diasease in Saudi Arabia
