Background/Aims:
To evaluate the technical feasibility and clinical efficacy of double endoscopic nasobiliary drainage (ENBD) as a new method of draining multiple bile duct obstructions.
Methods:
A total of 38 patients who underwent double ENBD between January 2004 and February 2010 at the Asan Medical Center were retrospectively analyzed. We evaluated indications, laboratory results, and the clinical course.
Results:
Of the 38 patients who underwent double ENBD, 20 (52.6%) had Klatskin tumors, 12 (31.6%) had hepatocellular carcinoma, 3 (7.9%) had strictures at the anastomotic site following liver transplantation, and 3 (7.9%) had acute cholecystitis combined with cholangitis. Double ENBD was performed to relieve multiple biliary obstruction in 21 patients (55.1%), drain contrast agent filled during endoscopic retrograde cholangiopancreatography in 4 (10.5%), obtain cholangiography in 4 (10.5%), drain hemobilia in 3 (7.9%), relieve Mirizzi syndrome with cholangitis in 3 (7.9%), and relieve jaundice in 3 (7.9%).
Conclusions:
Double ENBD may be useful in patients with multiple biliary obstructions.
