Randomized Controlled Trial
Hyoscine butylbromide administered at the cecum increases polyp detection: a randomized double-blind placebo-controlled trial.
Removal of colonic polyps prevents progression of colonic neoplasia. Miss rates of polyps range from 5 % to 32 %. The effect of colonic contractility on polyp detection has not been studied adequately. Hyoscine butylbromide results in colonic spasmolysis and may improve polyp detection. ⋯ Hyoscine butylbromide administered at the cecum aids polyp detection. Further studies are required to determine the contribution of colonic spasm to polyp miss rates.

Fine-needle aspiration (FNA) guided by endoscopic ultrasonography (EUS) is important in mediastinal staging of non-small cell lung cancer (NSCLC). Training standards and implementation strategies of this technique are currently under discussion. The aim of this study was to explore the reliability and validity of a newly developed EUS Assessment Tool (EUSAT) designed to measure competence in EUS - FNA for mediastinal staging of NSCLC. ⋯ Competency in mediastinal staging of NSCLC using EUS and EUS - FNA can be assessed in a reliable and valid way using the EUSAT assessment tool. Measuring and defining competency and training requirements could improve EUS quality and benefit patient care.
