Introduction: Malignant biliary obstruction is a common complication in patients with malignant tumors of the pancreas, bile ducts, and periampullary region. In cases of advanced tumor infiltration or anatomical changes, endoscopic stenting is often impossible, requiring the use of alternative methods such as percutaneous transhepatic biliary drainage (PTBD) followed by placement of a self-expanding metal stent (SEMS).
Case report: We present a case of an 83-year-old female patient with unresectable pancreatic adenocarcinoma and liver metastases. After a failed attempt at endoscopic decompression due to tumor infiltration of the duodenum, PTBD was performed, followed by the placement of a SEMS, which restored full biliary patency.
Discussion: Percutaneous biliary stenting is an effective alternative in patients with unresectable malignant biliary obstruction and unsuccessful endoscopic access. Data from the literature demonstrate high technical and clinical success rates for this approach, comparable to endoscopic methods.
Conclusion: Percutaneous biliary stenting should be considered a reliable therapeutic option for patients with advanced malignant biliary obstruction when endoscopic access is not feasible.
