Abstract

Purpose: To evaluate the safety and effectiveness of core needle biopsy (CNB) under the assistance of hydrodissection (HDS). Materials and Methods: Of 2325 patients requiring biopsy of thyroid lesions, 21 high-risk patients with subcapsular nodules smaller than 10 mm were recruited into this study. All patients underwent HDS with 0.9% saline solution followed by ultrasound (US)-guided CNB with an 18-gauge semi-automated biopsy needle. The separation success rate (SSR) of the HDS, technical success rate (TSR) of CNB, histopathologic success rate (HSR), and complications were assessed. Results: Both the SSR of HDS and TSR of CNB were 100% (21/21). The HSR of the thyroid nodules was 85.7% (18/21). No major complications were recorded. Conclusion: HDS before CNB can successfully lead to safe biopsy of small subcapsular thyroid nodules.
