Percutaneous Transhepatic Cholangiodrainage (PTCD)-Related Hepatitis B Virus Reactivation in Obstructive Jaundice.

Background: Obstructive jaundice is a common clinical condition, often caused by malignant tumors such as hepatocellular carcinoma (HCC) or cholangiocarcinoma (CCA). Percutaneous transhepatic cholangiodrainage (PTCD) is a widely used intervention method to relieve biliary obstruction in patients with obstructive jaundice; however, the impact of PTCD on hepatitis B virus (HBV) reactivation has not been thoroughly studied. Methods: A retrospective analysis was conducted from January 2016 to December 2024 on 235 patients with obstructive jaundice who underwent PTCD. Demographic, clinical, and procedural data were collected, and multivariate logistic regression was used to identify risk factors for HBV reactivation. Additionally, Cox regression was used to evaluate the time-to-reactivation variables. Results: The HBV reactivation rate in the PTCD group was 21.7%, significantly higher than the 8.9% in the non-PTCD group. Key risk factors for HBV reactivation in the PTCD group included the absence of antiviral prophylaxis, postoperative infection, elevated preoperative HBV-DNA levels, and multiple biliary punctures. Moreover, Cox regression revealed that a lack of antiviral therapy and postoperative infection were associated with earlier HBV reactivation. Conclusions: PTCD significantly increases the risk of HBV reactivation in patients with obstructive jaundice, especially in those with high preoperative HBV-DNA levels and without antiviral prophylaxis. Early detection of HBV reactivation and the initiation of antiviral therapy are critical to improving patient outcomes. These findings underscore the need for careful monitoring of HBV status in patients undergoing PTCD.
