Clinical efficacy of ultrasound-guided percutaneous catheter drainage in treatment of liver abscess

Abstract

Objective To compare the clinical efficacy of ultrasound-guided percutaneous catheter drainage versus incision and drainage in the treatment of liver abscess. Methods Thirty-two liver abscess patients who underwent ultrasound-guided percutaneous catheter drainage from June 2015 to June 2016 at our hospital and 32 liver abscess patients who underwent incision and drainage from January 2014 to January 2015 at our hospital were included in this study. The cure rate, time to recovery of body temperature to normal, time to recovery of white blood cell count, time to extubation, hospitalization length, hospitalization cost, and occurrence of complications were compared between the two groups. Results The cure rate was significantly higher in the catheter drainage group than in the incision and drainage group (96.88% vs 84.38%, χ2 = 2.94, P>0.05). The time to recovery of body temperature to normal, time to recovery of white blood cell count, time to extubation, and hospitalization length were significantly shorter in the catheter drainage group than in the incision and drainage group [(3.13 ± 1.04) d vs (7.09 ± 1.42) d, (4.06 ± 1.32) d vs (7.28 ± 1.30) d, (10.03 ± 1.18) d vs (14.06 ± 1.16) d, (14.03 ± 1.15) d vs (18.03 ± 1.21) d; t =12.197, 9.831, 13.784, 14.091, P<0.05], respectively. The hospitalization cost was significantly less in the catheter drainage group than in the incision and drainage group [(8288.81 ± 355.43) yuan vs (12 771.98 ± 337.93) yuan, t = 51.711, P<0.05]. The complication rate was significantly lower in the catheter drainage group than in the incision and drainage group (3.13% vs 15.63%, χ2 = 6.56, P<0.05). Conclusion Ultrasound-guided percutaneous catheter drainage has the advantages of precise and easy operation, mild trauma, quick recovery, and low complication rate over incision and drainage in the treatment of liver abscess.
