There are currently no studies that define the incidence of IBD in Egypt. This is the first multicentre study that was designed to determine the frequency of colonoscopic diagnosis of UC and CD in four university hospitals and compare their findings.Patients matching the diagnostic colonoscopic criteria of ulcerative colitis (UC) or Crohn’s disease (CD) were selected and their findings were tabulated and included for each patient.The present study reported male predominance over female regarding IBD in Egypt.
