The learning curve for EUS-guided FNA (EUS-FNA) is formidable. Development of a phantom to assist in teaching the technique may be beneficial. This study assessed the feasibility of using a low-cost phantom made of commonly available materials to practice EUS-FNA. ⋯ Once validated, an EUS phantom made of simple components may become an invaluable educational tool for teaching EUS-FNA. Further studies are needed to determine how it affects the skills of gastroenterologists with and without EUS experience.

Randomized Controlled Trial Clinical TrialSingle bolus of midazolam versus bolus midazolam plus meperidine for colonoscopy: a prospective, randomized, double-blind trial.
The aim of this study was to determine whether a single bolus of meperidine in addition to midazolam improves patient tolerance during colonoscopy. ⋯ The addition of a single bolus of meperidine to midazolam improves patient tolerance and lessens pain during colonoscopy without significantly increasing the frequency of side effects or prolonging recovery time.

Diagnostic potential of near-infrared Raman spectroscopy in the colon: differentiating adenomatous from hyperplastic polyps.
Near-infrared Raman spectroscopy is a promising optical technique for GI tissue diagnosis. This study assessed the diagnostic potential of near-infrared Raman spectroscopy in the colon by evaluating its ability to distinguish between adenomatous and hyperplastic polyps. ⋯ Near-infrared Raman spectroscopy differentiated adenomatous from hyperplastic polyps with high diagnostic accuracy. To our knowledge, this is the first demonstration of the potential of near-infrared Raman spectroscopy for differentiation of colonic polyps during GI endoscopy.

Comparative StudyEffectiveness of open-access endoscopy in routine primary-care practice.
Direct referral of patients for endoscopic procedures without prior consultation (open-access endoscopy) has become commonplace. However, the effect of open-access endoscopy on the care of patients in routine clinical practice has not been studied. ⋯ Open-access endoscopy in the primary-care setting is effective to the extent that subsequent GI consultations are rare and the level of compliance with endoscopist recommendations is high. However, documentation of communication of the results of endoscopy with the patient can be improved.
