Prior abdominal surgery as a potential risk factor for colonic diverticulosis or diverticulitis.

Background: Abnormal colonic pressure profiles have been associated with an increased risk of colonic diverticulosis. A surgical history is a known risk factor for abdominal adhesions and these may lead to increased intraluminal colonic pressure.

Aim: To assess whether previous abdominal surgery is associated with colonic diverticulosis or diverticulitis.
