Alternative approaches to polyp extraction in colonoscopy: a proof of principle study.

Background And Aims: A limitation of determination of the completeness of resection in polypectomy is polyp fragmentation. When a polyp fragments, the pathologist cannot determine resection completeness. Alternative approaches to reduce polyp fragmentation include reducing shearing forces on the polyp or removing polyps through the instrument channel.

Alcohol and the Intestine.

Alcohol abuse is a significant contributor to the global burden of disease and can lead to tissue damage and organ dysfunction in a subset of alcoholics. However, a subset of alcoholics without any of these predisposing factors can develop alcohol-mediated organ injury. The gastrointestinal tract (GI) could be an important source of inflammation in alcohol-mediated organ damage.
