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.).

Comparative StudyAssessing the realism of colonoscopy simulation: the development of an instrument and systematic comparison of 4 simulators.
No useful comparative data exist on the relative realism of commercially available devices for simulating colonoscopy. ⋯ The CSRQ is a useful instrument for quantifying simulator realism. There is no clear "first choice" simulator among those assessed. Each has unique strengths and weaknesses, reflected in the differing results observed across 9 subscales. These findings may facilitate the targeted selection of simulators for various aspects of colonoscopy training.

Psychomotor recovery and blood propofol level in colonoscopy when using propofol sedation.
It is commonly recommended that patients refrain from driving for 24 hours after endoscopy for which sedation is given. ⋯ Although consistent findings on the number connection test and driving simulation (psychomotor recovery) test are present as early as 1 hour after propofol sedation, a study of additional numbers of patients as well as different patient populations are needed before these results can be universally recommended.

Validation of a novel method for assessing competency in polypectomy.
There is a gap in the formal assessment of technical skills in polypectomy that is now considered an integral part of colonoscopy. Polypectomy has been shown to reduce the incidence of colorectal cancer but does have associated complications. Polypectomy competency assessment should arguably be a part of the certification process for all endoscopists. A polypectomy competency assessment tool (Direct Observation of Polypectomy Skills [DOPyS]) has been developed and its reliability examined. This study examined the ability of the DOPyS to reliably distinguish between endoscopists with different levels of experience, ie, its construct validity. ⋯ The results of the analysis suggested that the DOPyS could reliably differentiate between polypectomies performed by endoscopists of different levels of experience, but only if the assessors were trained in the use of the assessment tool. Training is therefore required to use this tool reliably.

Comparative StudyComparison of EUS-guided rendezvous and precut papillotomy techniques for biliary access (with videos).
Precut papillotomy after failed bile duct cannulation is associated with an increased risk of pancreatitis. EUS-guided rendezvous drainage is a novel alternative technique, but there are no data comparing this approach with precut papillotomy. ⋯ In this study, the EUS-guided rendezvous technique was found to be superior to precut papillotomy for single-session biliary access. Prospective randomized trials are needed to confirm these preliminary but promising findings.
