Percutaneous transhepatic biliary drainage. Series with a technical note.

Barium duodenography was performed simultaneously with percutaneous transhepatic cholangiography in 11 patients with failed transhepatic visualisation of the duodenum prior to percutaneous transhepatic biliary drainage (PTHBD). The advantages of this modification, not only to guide PTHBD but also in percutaneous tumour biopsy and coeliac gangliolysis, are discussed with particular reference to developing economies, where newer cross-sectional imaging modalities are not available. There were no complications related to the duodenography.
