Considering double contrast barium enema and its demise: a case for systematic videorecording of colonoscopy.

Double contrast barium enema (DCBE) continues its decline. One area where DCBE and CT colonography surpass colonoscopy is in documentation. Colonoscopy could improve documentation by systematic videorecording of examinations (or at least of the withdrawal portions). Investigation of the impact of systematic videorecording of colonoscopy on quality, cost, and medical-legal risk is warranted.
