Findings during screening colonoscopies in a Middle Eastern cohort.

Background/aims: Colorectal cancer is the most common cancer in males and the third most common cancer in females. We aim to determine the polyp and adenoma prevalence in a cohort of patients who underwent opportunistic screening colonoscopies.

Patients And Methods: A retrospective cohort study was conducted using an endoscopic reporting database of individuals seen at three tertiary care hospitals (two public hospitals and one private) in Riyadh, Saudi Arabia.

Predictors of failure of endoscopic retrograde cholangiography in clearing bile duct stone on the initial procedure.

Background/aims: The aim of this study is to predict cases where the clearance of the biliary system from stones at the initial endoscopic retrograde cholangiopancreatography (ERCP) might be of value for better risk-stratifying patients. We attempted to identify factors that are associated with a higher failure rate of clearing the biliary system on the index ERCP.

Patients And Methods: This is a retrospective study from January 2008 to January 2015.
