Clinical analysis of digital subtraction angiography-guided percutaneous transhepatic cholangial drainage in treatment of acute obstructive suppurative cholangitis
Objective To investigate the clinical effect of digital subtraction angiography(DSA)-guided percutaneous transhepatic cholangial drainage(PTCD)in treatment of acute obstructive suppurative cholangitis(AOSC).Methods The relevant data of DSA-guided PTCD in treatment of AOSC patients were collected to analyze its safety and effectiveness.Results Among the 70 patients,there were 2 cases of bleeding,1 case of drainage tube blockage,and 1 case of drainage tube detachment,and no other serious surgical related complications occurred.The symptoms of 66 patients were improved from 3 to 7 d after PTCD compared with those before PTCD,and 4 patients died during hospitalization.The average daily bile drainage volume of patients was(650±130)m L,and the changes of leukocyte,total bilirubin,alanine aminotransferase and alkaline phosphatase indexes before and after surgery were statisti-cally significant(P<0.05).Conclusion DSA-guided PTCD in treatment of AOSC is a safe and effective minimally invasive method with high technical success rate,which can timely relieve obstruction,improve symptoms,reduce mortality,and create opportunities and conditions for secondary surgery or interventional therapy.
