Intraportal stent placement combined with right portal vein embolization against advanced gallbladder carcinoma

We describe herein the first successful implementation of intraportal stent placement combined with right portal vein embolization as preoperative management against far advanced gallbladder carcinoma. The patient was a 66-year-old woman with obstructive jaundice, in whom computed tomography confirmed that gallbladder carcinoma had invaded the liver and that massive lymph node metastases involved the hepatoduodenal ligament. Portography also revealed severe stenosis of the main portal trunk to less than 2 mm in diameter. To prevent the contribution of intraportal thrombosis and ensure postoperative liver functional reserve, an intraportal metallic stent implantation was conducted simultaneously with right portal vein embolization via a single route using the percutaneous transhepatic approach. There were no complications following this technique, and the patient subsequently underwent hepato-ligament-pancreatoduodenectomy. The resected specimen disclosed a well-expanded stent containing no thrombus. This method could therefore be an amenable strategy for the preoperative treatment of far advanced biliary malignancies in selected patients.
