| Objective: To compare the results of percutaneous biopsy and EUS-guided tissue acquisition (EUS-TA) for liver tumors. Methods: Patients in which biopsy was attempted for histological diagnosis of liver tumors between January 2019 and February 2024 were retrospectively reviewed. Percutaneous biopsy was performed using an 18G needle. EUS-TA was performed with rapid-onsite evaluation(ROSE) using FNB needle. Results: 70 patients were included. 42 were percutaneous biopsy group (P group) and 28 were EUS-TA group (E group). The reasons for selecting EUS-TA were: simultaneous examination with other lesions (pancreatic masses, lymph nodes) in 14, difficulty of percutaneous biopsy in 6, and others in 8. The accurate diagnosis rate was 90% in P group and 100% in E group (P=0.13). 3 patients (7%) in P group had pain requiring analgesic. In one patient with hepatocellular carcinoma, tumor hemorrhage from a different site than the puncture site was observed 4 days after the EUS-TA. Although hemorrhage stopped spontaneously, 10 days after the initial hemorrhage there was a second hemorrhage due to tumor rupture and he died. Conclusion: EUS-TA for liver tumors shows good diagnostic performance and is effective in cases where percutaneous biopsy is difficult, such as caudate lobe tumors. It can also be added if it is difficult to obtain sufficient specimens during EUS-TA targeting pancreatic masses or lymph nodes. |
