Core Tip
Core Tip: This article evaluated a retrospective study by Qiu et al, which demonstrated that ultrasound-guided percutaneous catheter drainage for non-liquefied pyogenic liver abscesses reduced hospitalization duration, accelerated fever resolution, and promoted abscess volume reduction compared to traditional “wait-for-liquefaction” management, with no increased procedural risks. Current clinical practice recommends early percutaneous catheter drainage for patients with severe symptoms or compromised immunity, whereas antibiotic therapy remains the primary approach for small abscesses or mild cases. Dynamic imaging reassessment and multidisciplinary collaboration are critical for individualized management. Large-scale multicenter prospective randomized controlled trials are still required to validate the efficacy of this precision-driven paradigm shift in pyogenic liver abscess treatment.
