Treatment of pyogenic liver abscess by surgical incision and drainage combined with platelet-rich plasma: A case report

Figure 1 Computed tomography of the upper abdomen before surgery. Images show multiple low-attenuation masses with vague boundaries in the right lobe of the liver. A lesion measuring 9 cm × 8 cm is located in the upper posterior segment of the right lobe. A: The abscess is completely liquefied (white arrow); B: There seems to be septa inside the abscess (white arrow).

Figure 2 Intraoperative findings. A: Filling of the abscess cavity with platelet-rich plasma (PRP) (white arrows); B: After filling with PRP, the abscess surface was covered with hemostatic gauze, and an abdominal drainage tube was placed (white arrows).

Figure 4 Radiographs taken 3 d after the procedure. A: The intrahepatic low-attenuation lesion was filled with platelet-rich plasma (white arrow); B: The drainage tube (white arrow) was visible in the abscess cavity.

Figure 5 Radiographs taken 7 d after the procedure. A: A hole in the abscess cavity was noted, representing the space where the drainage tube was placed (white arrow); B: The low-attenuation lesion was significantly smaller (white arrow).
