Abstract

Background:Persistent enlargement of major salivary glands (SGs) is one of the main risk factors for B-cell lymphoma in primary Sjögren’s syndrome (pSS). The Ultrasound-guided Core Needle Biopsy (US-guided CNB) could be a novel technique for the management of SGs enlargement in pSS (1).Objectives:To evaluate the procedure safety and the patient tolerance of US-guided CNB in pSS patients with major SGs enlargement.Methods:Consecutive patients, with either definite or clinically suspected pSS, and with clinical indication for SGs biopsy due to persistent glandular enlargement were screened for US-guided CNB from September 2019 to December 2020. All patients were evaluated clinically between 1 and 2 weeks and 12 weeks following US-guided CNB. All patients were asked to complete a questionnaire to report post-procedural complications (Figure 1, English version) and intra- and post-procedural pain Visual Analogue Scale (VAS). The complications were classified as transient (<12 weeks) or persistent (≥12 weeks).Results:US-guided CNB was performed in 21 glands (12 parotid and 9 submandibular glands) in 20 pSS patients. 16/20 (80%) patients fulfilled the ACR-EULAR classification criteria for pSS (2). The mean age at the time of biopsy was 62.1 (±11.7) years. US-guided CNB was well tolerated, no long-term complications were reported in the follow-up period (mean 9.5 ±5.7 months). Only transient complications were noticed in 11 patients (55%). In particular, two cases of local swelling at the biopsy site lasting no more than 6 days, one case of local bleeding and subsequently hematoma of the submandibular area, one case of transient facial paresis (lasting less than one hour), seven cases of post-procedural mild local pain, that resolved within 10 days without the need of analgesics (Table 1). The procedure was well tolerated, with a very low reported intra-operative pain (mean VAS 1.74 ±2.49) and a mean post-operative pain VAS of 1.39 (±2.33). The biopsy sampling was diagnostic in 19/20 patients (95%).Conclusion:US-guided CNB represents a novel approach for the management of pSS patients with SGs enlargement. This procedure shows a remarkable patient safety and tolerance, allowing an adequate glandular sampling and definite diagnosis in almost all the studied patients.
