[Endoscopic perfusion manometry of the common bile duct in the post-cholecystectomy syndrome].

In 14 cholecystectomized patients with recurrent attacks of pain endoscopic manometry of the c.b.d. was carried through after thorough exclusion of organic diseases. Two different conspicuous types of pressure behaviour became evident: In 8 pat. the pressure in the c. b. d. increased steadily during perfusion and finally triggered pain, identical to the spontaneous one according to localization and character. In 6 pat. even after prolonged perfusion no pain emerged and the c. b. d.-pressure remained unchanged. As the increase in c. b. d.-pressure connected with provocation of pain was reproducible, perfusion manometry in the c. b. d. seems to be a mean of delimitating and objectifying functional disturbances of the bile duct.
