title: [Endoscopic perfusion manometry: diagnosis of functional biliary disorders].
abstract: During the last years the endoscopic perfusion manometry developed many new recognitions about the courses of pressure and motility at the sphincter Oddi. The clinical and experimental application of the method concentrated itself to the proof of functional disturbances. Many results are contradictory and a whole series of questions is unsolved. The own investigations concentrated themselves on pressure measurements in the common bile duct in patients with removed gallbladder, in whom by comprehensive diagnostic measures no organic disease of the biliary tract could be found. Two groups of patients were compared. Patients of group 1 (n = 14) had no biliary symptoms after cholecystectomy. The patients of the second group (n = 20) continued to have biliary complaints after cholecystectomy, or they again occurred after symptom-free interval. At the beginning of the investigation the pressure in the common bile duct was the same in the two groups. In group 1 the pressure remained constant also during the manometry and the patients remained without any complaints. However, in group 2 a gradual increase of pressure and biliary complaints developed during manometry. These occurred after an average pressure increase of 8 Torr. The velocity of the increase of pressure well correlated with the intensity of the complaints. The symptoms during manometry were identical with those cited in the anamnesis. The pressure increase in the common bile duct is regarded as an expression of a functional disturbance of the sphincter of Oddi. The constant perfusion rate (1.3 ml/min) in this group of patients is sufficient as volume load, in order to detect a disturbed drainage capacity of the papilla. On its part the increase of the pressure is responsible for the evocation of the complaints.
