title: Percutaneous transhepatic cholangiography: Ibadan experience.
abstract: Our experience using the teflon method in carrying out transhepatic cholangiography is described. A teflon needle (20 gauge) was used instead of the conventional Chiba needle. The number of successful examinations and their complication rate are comparable with examination carried out with Chiba needle. The ease of the procedure with the teflon needle and its relative cheapness make this technique preferable, although not without risks, especially in the developing countries where inadequate funds are available for health care.
