Diagnostic value of endoscopic ultrasound-guided fine needle aspiration for portal vein tumor thrombus (with video) / 中华消化内镜杂志

ABSTRACT

To evaluate the diagnostic value of endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) for portal vein tumor thrombus, data of patients with digestive system malignant tumors combined with portal vein tumor thrombus diagnosed by CT or magnetic resonance imaging who underwent EUS-FNA from April 2015 to July 2020 in the Second Affiliated Hospital of Soochow University were collected. A total of 7 patients were included, with 2 cases of primary hepatocellular carcinoma, 3 cases of primary pancreatic carcinoma and 2 cases of primary gastric cancer. EUS-FNA was successfully performed in 7 patients with portal vein embolus. Pathological examination of portal vein embolus showed 5 cases of malignant tumor. No tumor cell was found in 2 cases. There were no complications such as local hematoma, abdominal hemorrhage or infection in all patients. EUS-FNA is safe and effective for patients diagnosed as having malignant tumors with portal vein embolus.
