ABSTRACT
Objective To analyze the therapeutic effect of percutaneous transhepatic cholangial drainage (PTCD) in the treatment of bile duct obstruction in patients with malignant hilar bile duct carcinoma,and to discuss the clinical application and practical value of PTCD.Methods A total of 55 patients with malignant biliary obstruction were divided into the PTCD group (30 cases who recieved percutaneous transhepatic cholangial drainage) and the control group (25 cases who recieved endoscopic stent implantation).Observed the preoperative and postoperative biochemical indexes of PTCD group,including serum total bilirubin (TB),serum direct bilirubin (DB),serum alanine aminotransferase (ALT) and serum glutamic acid amino turn shift of aspartate aminotransferase(AST) and serum alkaline phosphatase(AKP).Compared the effect rate and postoperative survival time of the two groups through postoperative follow-up.Results The TB,DB,ALT,AST and APK of PTCD group one week after operation changed obviously compared with the relative index before opreation with statistically significant differences (P<0.05), which indicated a significant improvement of biochemical indicators.The treatment efficiency of the PTCD group and the control group were 83.3% and 64.0% respectively, and survival time of the two groups were(7.5±2.6)months and(4.8±2.8)months respectively.Results of the PTCD group was significantly better than that of the control group,and the differences were statistically significant(P<0.05).Conclusion All the patients with PTCD get better biochemical indicators and longer postoperative survival time,and the interventional therapy PTCD can be used as an effective clinical treatment method for bile duct obstruction with malignant hilar bile duct carcinoma.
