Sessile serrated lesion (SSL) detection is an important colonoscopy quality indicator; however, the optimum modality for detection is not known. This single-center randomized controlled trial compared narrow-band imaging (NBI) with linked-color imaging (LCI) for SSL detection. There was no difference in outcomes between the two modalities. Operator experience, good bowel preparation, and longer withdrawal times were associated with higher SSL detection rates.

Gastrointestinal endoscopy is largely dependent on medical devices, and the European Union has recently introduced stricter rules and regulations for the approval of such devices. This paper discusses the requirements of the new legislation and its implications for endoscopy, including the increased need for clinical trials and for endoscopists with suitable expertise to consider becoming members of the expert panel for endoscopy devices.
