Hepatic Tract Plug-Embolisation After Biliary Stenting. Is It Worthwhile?

AbstractPURPOSE:
PTC and stenting procedures are associated with significant risks including life-threatening haemorrhage, sepsis, renal failure and high mortality rates. PTC tract closure methods are utilised to reduce haemorrhagic complications despite little evidence to support their use. The current study assesses the incidence of haemorrhagic complications following PTC and stenting procedures, both prior to and following the introduction of a dedicated expanding gelatin foam-targeted embolisation liver tract closure technique.
MATERIALS AND METHODS:
Haemorrhagic complications were retrospectively identified in patients undergoing PTC procedures both prior to (subgroup 1) and following (subgroup 2) the introduction of a dedicated targeted liver tract closure method between 9/11/2010 and 10/08/2012 in a single tertiary referral centre. Mean blood Hb decrease following PTC was established in subgroups 1 and 2. Kaplan-Meier life-table analysis was performed to compare survival outcomes between subgroups using the log-rank test.
RESULTS:
Haemorrhagic complications were significantly reduced following the introduction of the targeted PTC tract closure method [(12 vs. 3 % of subgroups 1 (n = 101) and 2 (n = 92), respectively (p = 0.027)]. Mean blood Hb decrease following PTC was 1.40 versus 0.68 g/dL in subgroups 1 and 2, respectively (p = 0.069). 30-day mortality was 14 and 12 % in subgroups 1 and 2, respectively. 50 % of the entire cohort had died by 174 days post-PTC.
CONCLUSION:
Introduction of liver tract embolisation significantly reduced haemorrhagic complications in our patient cohort. Utilisation of this method has the potential to reduce the morbidity and mortality burden associated with post-PTC haemorrhage by preventing bleeding from the liver access tract.
