The 5–5–1 criteria (> 5 minutes – 5 cannulation attempts – 1 unintended pancreas duct cannulation) were proposed by the European Society of Gastrointestinal Endoscopy to define difficult biliary cannulation. However, the criteria may be inappropriate for trainee-involved procedures. The authors developed criteria for difficult cannulation in trainee-involved procedures.
To optimize colonoscopy quality, several performance measures have been developed. These are usually assessed without distinction between the indications for colonoscopy. This study aimed to assess the feasibility of linking two national registries (one for colonoscopy and one for adverse events of gastrointestinal endoscopies in the Netherlands), and to describe the results of colonoscopy quality per indication.
Suboptimal lifting increases complexity of endoscopic mucosal resection (EMR) for benign colorectal polyps. Cap-assisted EMR (EMR-C) may allow fibrotic polyp tissue to be captured in the snare. This study evaluated the efficacy and safety of EMR-C for benign nonlifting colorectal polyps.
