Efficacy of Percutaneous Catheter Drainage in Management of Liver Abscesses Compared With Needle Aspiration

Background Liver abscesses differ in their aetiology, location, and number. Image‐guided percutaneous drainage techniques are the currently used management for liver abscesses. We conducted our study to compare the clinical safety and efficacy of percutaneous needle aspiration (PNA) to percutaneous catheter drainage (PCD). Methods A systematic review of major reference databases was undertaken in February 2022 for randomized controlled trials (RCTs) that compare PNA to PCD in treating liver abscess patients. The quality of the included trials was assessed using the Cochrane tool. Statistical meta‐analysis was conducted using RevMan and open meta‐analyst software. Results Fifteen RCTs were included in this review, with 1676 patients enrolled. The overall quality of the included trials was moderate, with most domains of unclear risk. PCD was superior to PNA in the success rate (RR = 1.23; 95% CI [1.12, 1.36], P < 0.00001), time for achieving 50% reduction of cavity size (MD = −2.32; 95% CI [−3.07, −1.57], P < 0.00001), and time for clinical improvement (MD = −1.92; 95% CI [−2.55, −1.28], P < 0.00001). The two modalities did not differ in the days of hospital stay, duration of IV antibiotics, and time needed for total or subtotal reduction of cavity size (P = 0.36, P = 0.06 and P = 0.40, respectively). High heterogeneity levels were detected. Regarding major complications, the two modalities were equally safe (P = 0.39). Conclusion PCD has a higher success rate and results in a faster 50% reduction in the abscess cavity size and clinical improvement. The two modalities are equally safe.
