Randomized Controlled Trial Comparative StudyRandomized trial comparing the 22-gauge aspiration and 22-gauge biopsy needles for EUS-guided sampling of solid pancreatic mass lesions.
To overcome limitations of cytology, biopsy needles have been developed to procure histologic samples during EUS. ⋯ Diagnostic sufficiency, technical performance, and safety profiles of FNA and FNB needles are comparable. There was no significant difference in yield or quality of the histologic core between the 2 needle types.

Randomized Controlled TrialHyoscine N-butylbromide does not improve polyp detection during colonoscopy: a double-blind, randomized, placebo-controlled, clinical trial.
Colonoscopy is used for the detection of neoplastic polyps, although a significant miss rate has been reported. Limited data suggest that the administration of the antispasmodic hyoscine N-butylbromide during colonoscopy improves polyp detection. ⋯ ISRCTN25405865.).

Randomized Controlled TrialStrategies for training in diagnostic upper endoscopy: a prospective, randomized trial.
Training simulators have been used for decades with success; however, a standardized educational strategy for diagnostic EGD is still lacking. ⋯ Structured simulator training supplementing clinical training in upper endoscopy appears to be superior to clinical training alone. Simulator training alone does not seem to be sufficient to improve endoscopic skills.

Randomized Controlled Trial Multicenter Study Comparative StudyPropofol sedation alone or in combination with pharyngeal lidocaine anesthesia for routine upper GI endoscopy: a randomized, double-blind, placebo-controlled, non-inferiority trial.
In patients undergoing routine upper EGD, propofol is increasingly used without pharyngeal anesthesia because of its excellent sedative properties. It is unclear whether this practice is non-inferior in regard to ease of endoscopic intubation and patient comfort. ⋯ Topical pharyngeal anesthesia reduces the gag reflex in patients sedated with propofol even though it does not seem to have an influence on the ease of the procedure and on patient or endoscopist satisfaction in adequately sedated patients.

Randomized Controlled Trial Comparative StudyA prospective, randomized study of EUS-guided celiac plexus neurolysis for pancreatic cancer: one injection or two?
The technique of alcohol injection during EUS-guided celiac plexus neurolysis (CPN) in patients with pancreatic cancer-related pain has not been standardized. ⋯ There were no differences in onset or duration of pain relief when either 1 or 2 injections were used. There was no difference in safety or survival between the 2 groups.
