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.

A Novel Model to Predict Inadequate Bowel Preparation Prior to Colonoscopy Incorporating Patients' Reactions to Drinking the Laxative.

Background And Aims: Prior studies have identified predictors of inadequate preparation with limited success. We aimed to build a model that could predict the likelihood of inadequate preparation by also including factors related to the patient's reaction to drinking the laxative preparation.

Methods: Demographic, clinical, and preparation-related data were prospectively collected on patients undergoing colonoscopy.
