The Efficacy Of Biliary Stent Placement Malignant Biliary Obstruction Through Endoscope;the Efficacy Of Biliary Stent Placement To Treat Malignant Biliary Obstruction Through Endoscope

Objectives To investigate the efficacy of biliary stent placement through endoscope to treat malignant biliary obstruction and compare it with surgical palliation.Methods Analysed the data of 31 cases of malignant biliary obstruction patients treated by biliary stent placement and the data of 29 cases of this kind disease patients treated by surgical palliation retrospectivelyResults (1)The percent of the successful biliary stent placement is 93.55%.(2)The function of liver can be protected through both biliary stent placement and surgical palliation, and their degree for it is not different obviously(p>0.05). (3)The rate of recent complications is 9.68% in the group of biliary stent placement while it is 17.24% in the surgical palliation group. It is not different obviously(p>0.05)between the two groups.(4)The median time in hospital of the patients treated by biliary stent placement is 5 days. It is shorter than this time of the patients who have surgical palliation which is 13 days(p<0.05). (5)The average unobstructed time of biliary after stent placement is 154.95 days and this time is 223.37 days in surgical palliation group. They are not different obviously(p>0.05).(6) In stent group,the average live time of patients is 182.06 days and it is 239.37 days in surgical palliation group. The two time is not different obviously(p>0.05).Conclusions (1)Bliary stent placement is safe and efficient. It has efficacy to malignant biliary obstruction.(2) The efficacy of stent placement is not worse than surgical palliation. So to the malignant biliary obstruction patients in advanced stage,the billiary stent placement can almostly replace the surgical palliation.
