A comparative evaluation of percutaneous catheter drainage for resistant amebic liver abscesses

A Comparative Study of Percutaneous Catheter Drainage Versus Percutaneous Aspiration in the Treatment of Liver Abscess: A Retrospective Study

“…Although, percutaneous placement of an indwelling catheter is the method most widely preferred to drain liver abscesses, recent studies have shown therapeutic needle aspiration to be a simpler, less costly and equally effective mode of treatment. 5,6,7,8,9,10 In 2007, Enver Zerem I and Amir Hadzic et al did the same comparative study and concluded that "Percutaneous Drainage is more effective than percutaneous needle aspiration in the management of liver abscess. Percutaneous needle aspiration can be used as a valid alternative for simple abscesses 50mm in diameter or smaller."…”

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

“…Similar observations were recorded by other investigators as well. [9,26] Complications such as haemorrhage, pleural effusion/empyema, persistent bile drainage, catheter displacement, sepsis, etc. have been reported with both PNA (4% in series of Baek et al).…”

“…It can be said that in recent years image-guided percutaneous treatment (Needle aspiration or catheter drainage) has replaced surgical intervention as the primary treatment for liver abscess. [6][7][8][9] The major advantages of PNA over PCD are: 1) It is less invasive and less expensive; 2) Avoids problems related to catheter care; and 3) Multiple abscess cavities can be aspirated easier in the same setting. [10,11] However, in our study we had a success rate which was significantly lower than with catheter drainage.…”

Liver abscess-various modalities of treatment and its clinical outcome

“…10,6 The studies of Jaipal Singh and Sonnenberg were on amoebic abscesses and Wong and Gerz of studied only on pyogenic abscesses with other comorbid conditions such as malignancy and biliary stents, which prolonged the duration of drainage.…”
