[Stenosis of the papilla of Vater--clinical picture and possibilities of therapy].

Stenosis of the ampulla of Vater is encountered in as many as 10% of patients with biliary diseases. In general it is classified as tumourous, inflammatory of functional stenosis. In the clinical picture biliary dyspepsia associated with cholestasis predominates. The cause of functional stenosis of the ampulla of Vater is not known. In the development of inflammatory stenosis most frequently iatrogenic damage of the ampulla during revision of the biliary pathways participates or repeated passage of concrements in cholecystolithiasis. Treatment of tumours of the ampulla of Vater is surgical, treatment of inflammatory stenosis is endoscopic by endoscopic papillotomy. In the treatment of functional stenosis a useful drug is hymecromon, as a rule combined with metoclopramide.
