Percutaneous treatment of large pyogenic liver abscess

Percutaneous needle aspiration versus catheter drainage in the management of liver abscess: a systematic review and meta-analysis

“…In addition, a recent retrospective study revealed that decreases in success rates are associated with subsequent aspiration attempts. 24 This finding confirms the conclusions of three of the RCTs. [19][20][21] The second reason for the low rate of success achieved by PNA relates to the size of the liver cavity or the volume of the abscess.…”

“…Thus, even with repeat aspirations, the success rate of PNA remains inferior to that achieved with PCD. In addition, a recent retrospective study revealed that decreases in success rates are associated with subsequent aspiration attempts . This finding confirms the conclusions of three of the RCTs .…”

“…also reported a larger mean volume of abscesses (425 ml) in patients in whom PNA failed in comparison with that in patients in whom it was successful (178 ml) ( P < 0.05). Other authors have drawn similar conclusions . Thick viscous pus and the rapid accumulation of pus are important causes of failure in both PNA and PCD .…”

“…Major procedure‐related complications were rare in either group. Recent studies report a low incidence of minor complications …”

Anterior Abdominal Wall Abscess Revealing a Pyogenic Liver Abscess - A Case Report

“…In fact, inflammatory phenomena linked to hepatic sepsis may cause thrombosis of the portal system or hepatic veins. [8] [9] More rarely, large abscesses may rupture either into the peritoneal cavity or into adjacent structures (including the pleural and pericardial spaces). To our knowledge, no case of rupture into the parietal wall of the abdomen has been reported before.…”
