Abstract:

Objectives: In this study, we aimed to present our results and experience in percutaneous metallic stenting in patients with malignant biliary obstruction. Materials and Methods: Between June 2013 and August 2017, 40 patients (21 female, 19 male) with malignant biliary obstruction treated with percutaneous self-expandable uncovered metallic stents were retrospectively evaluated. Demographic data, diagnoses, number and type of procedure, technical and clinical success rates, time from placement of the first catheter into the biliary system to stenting, survival time, 30-day mortality, stent patency and complications were evaluated. Results: The mean age of the patients included in the study was 65 years (range: 40-90 years). The patients were diagnosed with pancreatic cancer (n=21), cholangiocellular cancer (n=7), gastric cancer (n=5), metastatic cancer (n=3), duodenum cancer (n=2) and hepatocellular cancer (n=2). A total of 66 stents were successfully implanted in the biliary system. The technical success, clinical success in the first week and in the first month of the procedures was 95%, 88% and 85% respectively. The survival time of the patients was 5.3 months (range: 1.5-9.5 months) and the 30-day mortality was 27.5%. Stent patency was 3.7 months (range: 1.5-6.5 months), the average time from catheter insertion to stenting in the first month was 10 days (range: 1-22 days) and in all patients the average was 30 days (range: 1-210 days). Conclusion: Percutaneous self-expandable uncovered metallic stenting process in patients with malignant biliary obstruction who are not suitable for surgery and endoscopic treatment or endoscopic treatment is unsuccessful, is a reliable and effective method as palliative treatment.
