Design outcomes

Primary

Measure	Time frame
The risk of colonic adenomas is calculated. The risk of colonic adenomas in the study group is compared with a group of patients screened for livertransplantation with gastroduodenoscopy and colonoscopy in the same period. In this control group patients are excluded with a disease with an increased risk of coloncancer (i.e. Primary biliairy cholangitis).	—
