[Endoscopic diagnosis and therapy of benign stenosis of Vater's papilla].

Out of 921 endoscopic papillotomies (EPT) 110 (12%) were performed in patients with benign stenosis of the papilla of Vater. Among these patients were 96 after cholecystectomy and 14 with gallbladder in situ. The diagnostic aspects of the stenosis of papilla and the complications of EPT were investigated on the basis of these patients. The dilation of the bile ducts is not a specific criteria for the diagnosis of papilla-stenosis. Dilatation could develop after cholecystectomy despite the normal sphincter pressure. The complication rate in patients with stenosis of papilla of Vater is increased (13.6%) in comparison with the patients with biliary stones (8.8%). This can be account for the increased number of haemorrhage and cholangitis.
