Introduction:
Treatment of major iatrogenic and non-iatrogenic bile duct injury (BDI) often requires delayed surgery with interim external biliary drainage. Percutaneous transhepatic cholangiography (PTC) with biliary catheter placement and endoscopic retrograde cholangiography (ERC) with stent placement have been used to bridge defects. In some patients, bridging the defect cannot be achieved through ERC or PTC alone.
Materials and methods:
Two patients with major BDIs, one iatrogenic and one non-iatrogenic underwent an extraluminal PTC/ERC rendezvous with placement of a fully covered self-expandable metal stent (SEMS) for the acute management of BDI with substantial loss of bile duct length.
Results:
In both patients the intraperitoneal PTC/ERC rendezvous with SEMS placement was successful with no complications after 12 and 18 months follow-up, respectively.
Discussion:
This study is the first to report a standardized approach to the acute management of iatrogenic and non-iatrogenic major BDIs using extraluminal intraperitoneal PTC/ERC rendezvous with placement of a fully covered SEMS. The described technique may serve as a "bridge to surgery" strategy for patients where definitive management of BDIs are deferred. However, long-term data of the success of this technique, specifically the use of a SEMS to bridge the defect, are lacking and further investigation is required to determine its role as a definitive treatment of BDIs with substance loss.
Conclusion:
PTC/ERC rendezvous with restoration of biliary continuity and internalization of bile flow is particularly useful for patients who have previously failed ERC and/or PTC alone, and in whom immediate surgical repair is not an option.
