Background:
Percutaneous transhepatic biliary drainage (PTBD) is a common procedure for biliary obstruction jaundice caused by biliary tract obstruction. PTBD can be performed using external or external-internal methods, by the right or left lobe approach. However, differences in both the method used and the hepatic approach may affect success rates and complications. Therefore, this study aimed to examine the outcomes and complications of PTBD and compare them according to different methods and hepatic approaches.
Methods:
Patients who underwent PTBD procedures in our interventional radiology department due to benign or malignant pathologies between March 2021 and March 2024 were included in the study. The diagnoses of the patients, and total and direct bilirubin values before and after the procedure were recorded. The clinical results and the complications of PTBD were compared statistically according to the hepatic approach and method. Univariate logistic regression analysis was performed to determine significant factors associated with PTBD success and complications.
Results:
Sixty patients were included in our study (32 men, 28 women; mean age: 67.14±13.61 y). The most common indication was malignant bile duct obstruction (90%). The obstruction was mostly at the level of the common bile duct (46.7%). The success rate of PTBD was the highest with the left-side external biliary drainage approach (left-side external biliary drainage, 81.2%; right-side internal-external biliary drainage, 77.8%; right-side external biliary drainage, 69.2%; P =0.596). The complication rate was higher for right-side access (right side 15.9%, left side 12.5%, P =0.744). Univariate logistic regression analysis revealed that PTBD success in females was 5 times higher than in males [Exp( B ): 5.000, β: 1.609, P <0.05]. Univariate logistic regression analysis revealed that methods used, entry lobes, and entry levels did not significantly affect PTBD success and complication incidence ( P >0.05).
Conclusion:
All approaches and methods used during PTBD were associated with low complications and high success rates. Nevertheless, external biliary drainage with right hepatic access has the lowest clinical success rate and a higher complication rate than the left-lobe approach. We observed that left-sided external biliary drainage was the most successful method and had fewer complications.
