Effect of percutaneous transhepatic cholangial drainag + radiofrequency ablation combined with biliary stent implantation on the liver function of patients with cholangiocarcinoma complicated with malignant obstructive jaundice.

objectiveTo investigate the effect of percutaneous transhepatic cholangial drainage (PTCD) + radiofrequency ablation (RFA) combined with biliary stent implantation on the liver function of patients with cholangiocarcinoma complicated with malignant obstructive jaundice.

methodsRetrospective analysis of 120 patients with cholangiocarcinoma complicated with malignant obstructive jaundice were divided into the research group (n=60) and the control group (n=60) according to different treatments. The research group received PTCD + RFA combined with biliary stent implantation, while the control group received only PTCD combined with biliary stent implantation. The changes of liver function indexes before and after treatment, the condition of postoperative jaundice in different periods after operation, toxicity and survival time were observed.

resultsThere was no statistically significant difference between the two groups in general data (P>0.05). Before treatment, there was no statistically significant difference between the two groups in albumin (ALB), alkaline phosphatase (ALP), glutamyltranspeptidase (GGT), total bilirubin (TBil) and direct bilirubin (DBil) (all P>0.05). After treatment, the above indicators were all decreased (all P<0.05), and the patient's condition improved, but there was no significant difference between the research group and the control group (P>0.05). There were patients with postoperative jaundice in the two groups at 1 month, 3 months, and 6 months after surgery. The total incidence of postoperative jaundice in the research group and the control group within 6 months was 11.67% and 30.00%, respectively (P<0.05). After treatment, the aftereffects were observed in the research group (15.00%) and the control group (25.00%), including infection, cholangitis, and biliary bleeding, without statistical significance (P>0.05). There was no statistical significant difference in progression-free survival between the two groups (P>0.05), while patients in the research group had higher median survival and 1-year survival rates than those of the control group (both P<0.05).

conclusionAfter PTCD + RFA combined with biliary stent implantation was performed on the patients with cholangiocarcinoma complicated with malignant obstructive jaundice, the number of patients with postoperative jaundice at different time points was reduced; 1-year survival rate and median survival were increased; patents' liver function and condition were improved. Thus, this method is worthy of promotion and application.
