ABSTRACT
BACKGROUND:
The aim of this study was to evaluate the efficacy and safety of endoscopic bilateral biliary metal stent placement for hilar malignant obstruction. PATIENTS ANDMETHODS:
Twenty patients with unresectable malignant hilar biliary obstruction who had undergone endoscopic bilateral Y-configured biliary drainage with metal stents were enrolled as a study group (YMS group). Thirty-seven patients who had undergone bilateral drainage with plastic stents were selected as a historical control (PS group). Two newly designed metal stents for bilateral Y-configured placement were endoscopically deployed in a partial stent-in-stent manner in one session. Technical success, early complications, and stent patency were evaluated.RESULTS:
The technical success rate in the YMS group was 100%. Mild post-endoscopic retrograde cholangiopancreatography pancreatitis occurred in one patient in the YMS group and in two in the PS group. The success rate of biliary decompression was 95% in the YMS group and 89% in the PS group (P=0.65). During a median follow-up period of 7.3months, the incidence of stent occlusion in the YMS group was significantly lower than that in the PS group (30% vs 62%, P=0.028). Mean stent patency in the YMS group was 250days and that in the PS group was 115days (P=0.0061). Risk factors for stent occlusion were bile duct cancer (P=0.035) and the PS group (P=0.07) by multivariate analysis.CONCLUSION:
Single-session endoscopic bilateral biliary placement of newly designed metal stents for hilar malignant obstruction is safe and useful with a high technical success rate and a long patency period.
