Background And Objectives:
EUS-guided biliary drainage (EUS-BD) has emerged as a complementary technique for primary drainage or as a rescue technique after failed endoscopic retrograde cholangiography. The objective of this study was to demonstrate the feasibility of EUS-BD for malignant hilar stenosis (MHS), both as an initial and rescue procedure.
Patients And Methods:
This study was a retrospective work based on a prospective registry of patients with malignant drainage stenosis of the hilum. For this analysis, only patients who underwent EUS-BD drainage were included. The drainage procedure could be performed by EUS-BD alone or in combination with another technique, for initial drainage or reintervention.
Results:
Between January 2015 and September 2018, 20 patients were included. The mean patient age was 68 years. Seven patients had primary liver tumors and 13 had obstructions caused by metastasis. Four patients had Type II stenosis, 7 had Type IIIA, 2 had Type IIIb, and 7 had Type IV stenosis. Sixteen patients underwent EUS-guided hepaticogastrostomy (EUS-HGS) for initial drainage and four as reintervention. For initial drainage, 2 patients underwent EUS-HGS alone and 14 underwent EUS-HGS in combination with another technique: 11 combined with endoscopic retrograde cholangiopancreatography (ERCP), 2 with percutaneous transhepatic drainage, and 1 with ERCP and percutaneous transhepatic drainage. The technical success rate for EUS-HGS in the drainage of MHS was 100%, and the clinical success rate was 95%. The mean percentage of liver drained was 84%, with an average 1.7 endoscopic sessions and an average 2.7 protheses. The early complication rate was 35% and the mortality rate was 5%. Five EUS-HGS/ERCP combination drainage procedures were performed in one session and six were performed in two sessions with similar complication rates and percentages of liver segments drained.
Conclusion:
EUS-BD is a feasible and safe technique for initial drainage and for reintervention procedures. The EUS-HGS/ERCP combination seemed to be useful in cases of complex stenosis and could be performed during the same session or in two sessions.
