The aim of the prospective study was to evaluated the efficacy and the comp
lications of 2,820 ERCP-examinations in 1,717 consecutive patients (perform
ed 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 sto
nes on common bile tract, 87.5% for drainage in bile tract obstruction, res
pectively. 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% chola
ngitis, 1.3% bleeding, 0.2% perforation, 0.5% other respectively). The tota
l 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 papillo
