Improvement of successfulness of endoscopic retrograde cholangiopancreatography

Background and aim: Imaging of aimed duct and performing of planned endoscopic therapy are unsuccessful in 10–20% of endoscopic retrograde cholangiopancreatographies (ERCPs). The aim was to evaluate the possibilities for improvement of successfulness in a prospective study. Method: 84.0% out of 1012 ERCPs (including 41 cases of previous unsuccessful attempts of other examiners) were performed successfully in last 3-yr-period. The causes of failure were pyloric or duodenal stenosis in 26 patients (2.6%), duodenal diverticulum (DD) in 25 patients (2.5%), Billroth II. partial gastrectomy (B II) in 19 patients (1.9%…
