Optimal timing of pyogenic liver abscess evacuation: The role of early ultrasound-guided intervention

Figure 1 Percutaneous treatment of multiple liver abscesses (a total of 10) using needle aspiration for those < 30 mm and catheter drainage for those > 30 mm. A and B: Abscess collections prior to the intervention; C: Catheter placed in one of the abscess collections; D and E: The same liver region six weeks after the intervention; F: Same patient as in panels A-E, with six catheters visible shortly after the procedure.

Figure 2 Percutaneous drainage of a double abscess collection in the right liver lobe, formed two weeks after appendectomy. A: Two abscess collections in the right liver lobe; B: Transhepatic access to the abscess collection using the trocar technique; C: Vigorous irrigation of the abscess cavity with a 50/50 mixture of iodine and saline through a catheter; D: Scar formation in liver tissue three weeks post-intervention.
