Multicenter Study Comparative StudyAn adequate level of training for technical competence in screening and diagnostic colonoscopy: a prospective multicenter evaluation of the learning curve.
Various training programs in colonoscopy recommend that trainees should perform at least 100 to 200 procedures to be considered technically competent at diagnostic colonoscopy. ⋯ Competence in technically efficient screening and diagnostic colonoscopy generally requires experience with more than 150 cases. Also, factors associated with prolonged cecal intubation for typical trainees did not differ from those for experienced colonoscopists.

Randomized Controlled Trial Comparative StudyClinical efficacy of dexmedetomidine alone is less than propofol for conscious sedation during ERCP.
Propofol is an accepted method of sedation for an ERCP and generally achieves deep sedation rather than conscious sedation, and dexmedetomidine has sedative properties of equivalent efficacy. ⋯ Dexmedetomidine alone was not as effective as propofol combined with fentanyl for providing conscious sedation during an ERCP. Furthermore, dexmedetomidine was associated with greater hemodynamic instability and a prolonged recovery.

Multicenter StudyAn evaluation of endoscopic indications and findings related to nonvariceal upper-GI hemorrhage in a large multicenter consortium.
The majority of studies on upper-GI hemorrhage (UGIH) to date have been based on clinical experience at academic centers. There is limited information about patients with UGIH who are evaluated by endoscopy at nonacademic settings, which comprise the majority of endoscopic practices in the United States. ⋯ These results allow association of EGD findings with patient presentation. Furthermore, it allows us to characterize endoscopic findings in a particular patient population (those patients with UGIH) in clinical practice, outside of traditional academic medical centers. The CORI database is a valuable resource for characterizing the epidemiology of endoscopic findings and, in particular, patient populations and across diverse practice settings, thus, enabling the development of hypotheses for future studies.
