Background:
Bilateral endoscopic drainage is difficult in malignant hilar biliary obstruction. Recently, unilateral drainage in malignant hilar biliary obstruction has been shown to be equally effective. However, contrast injection leads to cholangitis. There have been no reported studies on contrast-free metal stenting in malignant hilar biliary obstruction. The present study was undertaken to evaluate the results of contrast-free unilateral metal stenting in type II malignant hilar biliary obstruction.
Methods:
We prospectively studied the results of unilateral metal stenting in type II malignant hilar biliary obstruction without contrast injection in 18 patients.
Results:
A successful endoscopic drainage was achieved in 100% (18/18) of patients with hilar strictures. Cholangitis and 30-day mortality occurred in none.
Conclusions:
Unilateral endoscopic metal stenting without contrast in type II malignant hilar biliary obstruction is a safe and effective method of palliation.
