Assessment of the Percutaneous Procedures Results
Ninety-seven LLDs with biliary complications underwent one to four sessions of interventional radiology assisted percutaneous procedures. Eighty-five of them underwent transhepatic or transperitoneal perihepatic bilioma drainage and no any drainage catheter was placed in 18 of these patients because the aspirated fluid was serous/purulent rather than bilious. Median time from LDH to percutaneous bilioma drainage was 21 days (min-max: 6-317 days). Median time from LDH to PTBD catheter insertion was 33 days (min-max: 24-78 days). Among 12 LLDs had a PTBD catheter insertion, ten underwent PTBD catheter assisted HJ, of which 7 had external and 3 had internal-external PTBD catheters.
