Measuring performance is essential for high quality colonoscopy. National registries have the potential to collect these data with minimum effort from the endoscopist. This study reports on the Dutch experience of linking registries for colonoscopy quality and adverse events, allowing calculation of national estimates of cecal intubation rate and adverse events, such as bleeding, perforation, and mortality.

Snare, avulsion, and thermal techniques have all been described for removal of benign nonlifting colorectal polyps but are associated with higher recurrence rates compared to their use for easily lifted polyps. In this study, cap-assisted endoscopic mucosal resection (EMR-C) for nonlifting polyps was shown to be effective with few adverse events. Although recurrence rates were similar to those with other approaches, and one third of polyps required an adjunctive technique, EMR-C seems to be another helpful tool for a tricky problem.
