The aim of this study was to evaluate the clinical efficacy and safety of the ultrasound-guided fine needle biopsy (UG-FNB) of the spleen in a large population of patients. We collected retrospectively the findings concerning the application of UG-FNB of the spleen from eight Italian clinical centers that utilized this technique for at least ten years. A data schedule was sent to all centers to collect information about techniques, results, and complications of UG-FNB of the spleen. We analyzed 398 biopsy procedures both on focal lesions (257 cases) and on splenic parenchyma (141 cases). The overall accuracy was 90.9% for the series as a whole, 84.9% for cytological sampling, 88.3% for microhistological sampling, and 90.3% for both cytological and histological sampling (double biopsy). Tissue core biopsy yielded better overall accuracy in patients with suspected splenic involvement by lymphoma (90.9% vs. 68.5% for cytology). The complication rate was low (no death cases, less than 1% for major complications, and 5.2% for all complications). No predictive factors were able to detect high-risk situations. The operator's skill (higher number of performed procedures) was significantly related to better overall accuracy. Conversely, the complication rate was not affected. UG-FNB of the spleen is a very effective diagnostic procedure with low risk for the patient. Aspiration cytology and core needle biopsy showed similar diagnostic yields, except for the diagnosis of splenic lymphoma, in which core needle biopsy obtained better results.
