Direct Cholangiography and Biliary Drainage

Bacteriobilia in percutaneous transhepatic biliary drainage: occurrence over time and clinical sequelaeA prospective observational study

“…PTBD was established as described previously (1)(2)(3); system was visualized after puncture with a Chiba needle, followed by puncture with a 5-Fr catheter, with needle and guide wire insertion through the stricture (if possible), dilatation, and insertion of a 10-Fr pigtail PTBD (phase 1). A few days later, dilatation with plastic bougies of increasing diameters was performed in one session, or in several sessions a few days apart, until a final PTBD diameter of 12-16 Fr was reached (16 Fr mainly to allow procedures such as cholangioscopy, etc.)…”

“…P ercutaneous transhepatic access to the biliary system via percutaneous transhepatic cholangiography (PTC) is an established method of diagnosing and treating biliary disorders, after the endoscopic retrograde approach has failed or has proved inadequate for complete drainage or treatment of difficult stones (1)(2)(3)(4). In patients with biliary pathology, biopsy or treatment usually has to be carried out by establishing a tract long enough to allow passage of a cholangioscope.…”

“…Με τη μέθοδο αυτή είναι δυνατή η λήψη υλικού για κυτταρολογική ή ιστολογική εξέταση. Οι θεραπευτικές δυνατότητες είναι παρόμοιες με αυτές της ERCP, εκτός από την σφιγκτηροτομή, αλλά εντοπίζονται περισσότερο στα κεντρικότερα χοληφόρα 60,65,66. Η διαδερμική διηπατική χολαγγειογραφία (PTC) αντενδείκνυται σε περιπτώσεις αιμορραγικής διαθέσης.…”
