[Benign stenosis of the papilla (author's transl)].

The diagnostics of benign stenosis of the papilla is based on the preoperative endoscopic retrograde cholangiopancreatography (ERCP) and preoperative cholangiography and debimetry with diagnostic dilatation of the papilla. The high rate of positive results achieved with these difficult procedures necessitate their use. The therapy of reversible stenosis consists of the eradication of the responsible inflammatory focus (cholecystolithiasis and choledocholithiasis). Irreversible stenoses of the papilla are without exception successfully treated with sphincterotomy or papillotomy.
