Abstract:

Objective To discussion the efficacy and safety of single channel and double chinese-made biliary stent in high biliary malignant hilar obstructive jaundice.Methods We reviewed the clinical data of 24 malignant hilar obstructive jaundice patients treated with single channel and double chinese-made biliary stent from October 2012 to December 2013 retrospectively.Of which 9 cases(study group)were used for single channel and double stenttreatment,and 15 cases(control group)were treated by the bilateral channel;We compared the number of intraoperative percutaneous puncture hepatic duct,radiation exposure doses,operation time,drainage effectiveness and complication rates in the two groups.Results The average number of percutaneous puncture hepatic duct in the study group was 1.44±0.53 times,which was significantly lower than the control group(3.73 ± 0.70 times).The fluoroscopy time and radiation exposure dose of study group was 1152.22±335.61s and 653.22±207.02mGy,which was slightly less than the control group(1236.93±463.43s and 727.00±348.52mGy),the difference was not statistically significant(P=0.638;P=0.572).Liver function was tested after 4W,the drainage effectiveness of study group and the control group were 88.9%(eight-nineths),86.7%(thirteen-fifteenths),the difference was not statistically significant.One case occurred bile leakage in the study group,2 patients with hemobilia in control group,both groups showed no serious complication.Conclusion The single channel and double chinese-made biliary stent to treat high biliary malignant hilar obstructive jaundice is minimally injured and effective,which can be selectively applied to treat patients with hepatic hilum malignant obstructive jaundice.
