    Abstract:
    OBJECTIVES: To evaluate therapeutic outcomes of intraluminal brachytherapy (ILBT) for malignant obstructive jaundice (MOJ) against stent alone. METHODS: The PubMed, EMBASE, Cochrane Library, CNKI, Wan Fang, VIP and ClinicalTrials.gov databases were searched for all relevant comparative studies from the earliest available date up to 1 May 2017. Subgroup analyses were performed according to the type of study design and type of stent. RESULTS: Twelve studies that compared ILBT versus stent alone were eligible. A total of 641 participants with MOJ were included in our meta-analysis. A total of 340 participants were treated with intraluminal brachytherapy (ILBT); the other 301 participants were treated with biliary stent alone (stent group). ILBT was associated with lower risk of stent occlusion (OR 0.19; 95% CI 0.13-0.28; P < 0.00001) and better mean survival (MD = 3.15; 95% CI 2.64-3.66; P < 0.00001) compared with stent alone. However, the two groups were similar in number of complications (OR 0.84; 95% CI 0.45-1.56; P = 0.578), post-treatment reduced level of total bilirubin (TBIL) (MD = 22.71; 95% CI - 7.24-52.65; P = 0.14), post-treatment reduced level of direct bilirubin (DBIL) (MD = - 3.67; 95% CI - 14.09-6.75; P = 0.49), post-treatment reduced level of alanine aminotransferase (ALT) (MD = 21.09; 95% CI - 5.09-47.28; P = 0.11) and post-treatment reduced level of aspartate aminotransferase (AST) (MD = 20.86; 95% CI - 45.86-87.58; P = 0.54). CONCLUSIONS: ILBT was significantly superior to stent alone in terms of stent occlusion and mean survival. Meanwhile, ILBT had comparable outcomes to stent alone in terms of complications and post-treatment reduced levels of TBIL, DBIL, ALT and AST. Therefore, ILBT may be considered a preferable technique for MOJ.
