Abstract

Objective: Evaluate the result of percutaneous biopsy under ultrasound guidance in the diagnosis of atypical liver tumors. Subjects and methods: An observation study was conducted on 68 patients with atypical liver tumors from January 2019 to June 2021 at the Diagnostic Imaging Department, National Cancer Hospital. Post-biopsied complications, histopathology, and related factors were analyzed. Results: The average age of 68 patients with atypical liver tumors was 57.3. The male/female ratio was 1.95/1. Twenty-four cases were benign liver tumors (38.2%), and 44 were malignant liver tumors (64.7%). The rate of early complications after biopsy is 2.9%, not requiring blood transfusion or emergency surgery. Complications of tumor seeding on the biopsy route and arterioportal fistula were not recorded within the 18-month follow-up. Compared with post-surgery histopathology, percutaneous liver biopsy showed an accuracy of 96.3%, an excellent agreement with the Kappa coefficient of 0.922. Conclusion: Liver percutaneous ultrasound-guided biopsy is a minimally invasive technique with high accuracy and safety, which is supposed to be the basis for the management and treatment of atypical liver tumors.
