ABSTRACT
Objective To explore the effects and safety of endoscopic parallel placement of double metal stents on unresectable hilar malignant obstruction.Methods The clinical data of 11 patients with malignant hilar obstructive jaundice due to advanced carcinoma who were treated with parallel placement of double biliary stents from January 2011 to September 2012 were retrospectively analyzed.Results Out of 11 patients,10(90.9％) were successfully embedded with double biliary stents and 4 were dead during the follow-up.There was no sign of stent occlusion during the follow-up period.The survival time ranges from 128 to 185 days.One case was lost during the follow-up and 5 others are still alive.Conclusion The endoscopic parallel placement of double biliary stents is effective and safe for patients with unresectable malignant hilar obstruction.
