Should patients with unresectable gallbladder cancer with hilar involvement undergo unilateral or bilateral percutaneous biliary drainage in the setting of cholangitis?

Abstract

Aim of the studyThis study aimed to evaluate the outcomes of patients with unresectable gallbladder cancer (GBC) with hilar involvement and cholangitis undergoing percutaneous transhepatic biliary drainage (PTBD).Material and methodsThis retrospective study comprised consecutive patients with unresectable GBC with cholangitis who underwent PTBD. The procedures were categorized as unilateral or bilateral. Bilateral PTBD was classified as simultaneous or sequential. The mean reduction in bilirubin at two weeks was recorded. Complications and mean overall survival were also recorded.ResultsThirty-three patients (mean age 54.5 years, 12 males) were included. Thirty patients underwent unilateral drainage. Sequential drainage of the contralateral system was performed in 11 patients. Simultaneous bilateral PTBD was performed in 3 patients. PTBD was technically successful in all patients. Mean reduction in bilirubin was 41.5% in the unilateral group. The fall of bilirubin in the simultaneous bilateral PTBD group was 39%. The mean follow-up duration was 36.5 days. No major complications were encountered. At the last follow-up, 7 patients were alive. The mean overall survival was 34.6 days.ConclusionsPatients with unresectable GBC and cholangitis frequently require bilateral drainage. However, prospective studies should be performed to evaluate whether a sequential or simultaneous PTBD should be performed.
