[Quality and competence in endoscopic cholangiography. Towards certainty].

Introduction: The American Society of Gastroenterology (ASGE) and the American College of Gastroenterolog (ACG) have established indicators to recognize high-quality studies in endoscopic retrograde cholagiopancreatography (ERCP). The indicators were: a) Pre-procedure: adequate indication, informed consent, assessment of the degree of difficulty of the procedure and antibiotic prophylaxis. b) Intraprocedure: cannulation, choledocholithiasis extraction and stents placement rates. c) Postprocedure: full documentation and complications rates.

Methods: Between October 2010 and October 2012 we performed a retrospective, descriptive, observational and self-evaluative study to assess the compliance with ERCP quality indicators proposed by the ASGE.

Results: Preprocedural indicators were evaluated in 734 studies. Cannulation, choledocolithiasis extraction and stents placement under the hiliar bifurcation rates were 96.2%, 95.4% and 100%, respectively. The complication rate was 5.6% and the mortality was 0.27%. The severity of complications was evaluated according to the classification of Masci (30 mild, 7 moderate and 4 severe).

Conclusions: Quality is a basic tool that allows the comparison between our actions and the indicators already predetermined as suitable. The appropriate indication is an indicator to improve. We believe that 12% of registered normal studies could be due to a difficult accessibility to magnetic resonance cholangiography in our health system. Achievement of the internationally validated indicators place us as a high-quality endoscopic cholagiography unit and as a training center with appropriate expertise.
