{Abstract}: UNASSIGNED: Biliary stent dysfunction is challenging to treat in clinic. The retrograde track method (RTM) has a promising clinical application in the reopening of dysfunctional biliary stents. This study aimed to evaluate the clinical value of the RTM in reopening dysfunctional biliary stents.
UNASSIGNED: From February 2013 to January 2020, 151 patients underwent percutaneous transhepatic biliary interventional procedures for reopening dysfunctional biliary stents at the First Affiliated Hospital of Zhengzhou University, and 25 patients (12 females, 13 males; mean age 63.12 years old) underwent the RTM after anterograde reopening dysfunction biliary stent failure. Technical success, clinical success, irradiation dose, procedure time, complications, and overall survival (OS) were recorded, and levels of total bilirubin (TBIL), direct bilirubin (DB), alanine aminotransferase (ALT), albumin (ALB), and carbohydrate antigen-199 (CA-199) were compared before treatment and 1 month after treatment.
UNASSIGNED: The technical and clinical success rates were 100% and 96%, respectively, and the irradiation dose and procedure times were 774.07±330.80 mGy and 45.16±9.48 min, respectively. Two patients (8%) experienced major complications. The median OS was 10.73 months [95% confidence interval (CI): 9.37-12.09]. Compared with pretreatment values, the mean levels at 1 month after RTM administration for TBIL (189.47±59.20 vs. 44.65±16.12 µmol/L), DB (144.21±55.83 vs. 27.95±13.86 µmol/L), ALT (89.62±30.85 vs. 49.44±14.25 U/L), and CA-199 (584.59±269.82 vs. 176.76±100.68 U/mL) showed significant decreases, while that of ALB (36.32±2.05 vs. 40.22±1.95 g/L) showed a significant increase (all P values <0.05).
UNASSIGNED: RTM is an effective alternative treatment method when anterograde reopening of a dysfunctional biliary stent occurs.
