Ultrasound-guided drainage of subcutaneous abscesses on the trunk is feasible

Abstract

Introduction: Subcutaneous trunk abscesses are frequent, and current treatment options generally involve incision. By contrast, the standard care for breast abscesses is ultrasound-guided drainage. The aim of this study was to evaluate the feasibility of ultrasound-guided drainage combined with antibiotics in the treatment of subcutaneous abscesses on the trunk.

Material and methods: In this prospective study, 27 patients were treated with ultrasound-guided needle aspiration and oral antibiotics. Follow-up was performed at a 3-6-day interval, and the procedure was repeated if the abscess was not obliterated.

Results: Treatment was initially successful in 25 of the 27 participants (93%); two patients went on to surgery. The median time from first treatment to the final control visit was nine days. The 25 patients with initial successful treatment were contacted after a median of 84 days, and six (24%) of these reported recurrence of an abscess at the puncture site. 88% of the patients reported that they were satisfied or very satisfied with ultrasound-guided drainage.

Conclusion: Our results indicate that ultrasound-guided drainage combined with antibiotics is feasible in the treatment of small subcutaneous abscesses on the trunk. Ultrasound-guided drainage was well-tolerated, had a high degree of success and short healing times. Additional randomised studies are needed to verify our findings.
