Feasibility analysis of ultrasound-guided percutaneous catheter drainage for pyogenic liver abscess in non-liquefied stages

This letter systematically evaluated a retrospective comparative study by Qiu <i>et al</i> investigating ultrasound-guided percutaneous catheter drainage (PCD) for pyogenic liver abscess management during the non-liquefaction phase. The results demonstrated that early ultrasound-guided PCD significantly shortened hospitalization duration, accelerated fever resolution, and promoted > 50% abscess volume reduction compared to delayed intervention after liquefaction, without increasing procedural risks. While challenging the conventional "wait-for-liquefaction" paradigm, the evidence quality limitations warrant caution, highlighting the need for multicenter prospective randomized controlled trials. Current clinical practice recommends early PCD for severe manifestations (persistent fever, leukocytosis) or immunocompromised patients (including those with diabetes), while prioritizing antibiotic therapy for small abscesses (diameter < 3 cm) or mild cases. Dynamic imaging reassessment and multidisciplinary collaboration remain essential for individualized management. This study provides critical evidence supporting the paradigm shift from empirical observation to precision intervention in pyogenic liver abscess management, though risk-benefit evaluation should precede widespread clinical adoption.
