[Success and complication rates of diagnostic and therapeutic endoscopic retrograde cholangiopancreatography--a prospective study].

The aim of the prospective study was to evaluated the efficacy and the complications of 2,820 ERCP-examinations in 1,717 consecutive patients (performed over a three-year period). The rate of success was 82.8% for diagnostic ERCP, 96.6% for endoscopic sphincterotomy, 76.8% for the extraction of stones on common bile tract, 87.5% for drainage in bile tract obstruction, respectively. The rate of all complications amounted to 7.9% (4.9% diagnostic ERCP, 9.2% therapeutic ERCP, in detail: 3.8% acute pancreatitis, 2.1% cholangitis, 1.3% bleeding, 0.2% perforation, 0.5% other respectively). The total mortality was 0.1% (three cases of death). The frequency of complications increased with the number of procedure at the papilla Vateri in patients, who underwent needle knife papillotomy in combination with standard papillotomy.
