Meta Analysis Comparative StudyMeta-analysis of randomized trials comparing the patency of covered and uncovered self-expandable metal stents for palliation of distal malignant bile duct obstruction.
Self-expandable metal stents (SEMSs) are used for palliation of malignant biliary obstruction. ⋯ CSEMSs have a significantly longer duration of patency compared with USEMSs in patients with distal malignant biliary obstruction. Stent dysfunction occurs at a similar rate, although there is a trend toward later obstruction with CSEMSs.

Randomized Controlled TrialTraining on an ex vivo animal model improves endoscopic skills: a randomized, single-blind study.
Animal models are used for training of different endoscopic procedures. Whether this really improves endoscopic skills remains controversial. ⋯ Hands-on training by using an animal ex vivo model improves endoscopic skills in both hemostasis and perforation closure. In clinical practice, the training improves the outcome of hemostatic procedures.

Training to competency in colonoscopy: assessing and defining competency standards.
How to define competency in colonoscopy, how to assess it, and how much training is required are questions that experts in endoscopy have grappled with since the advent of the procedure. ⋯ Learning curves for core colonoscopy skills are described. MCSAT scores of 3.5, cecal intubation rates of 85%, and intubation times of less than 16 minutes are recommended as minimal competency criteria. It takes on average 275 procedures to achieve competence in colonoscopy. This is more than previous gastroenterology training recommendations and far more than current training requirements in other specialties.
