Unlabelled:
Percutaneous drainage is currently the treatment of choice in liver abscess. The most commonly used technique is catheter placement but this procedure is not free of complications.
Objective:
To analyze the safety and efficacy of needle aspiration in the treatment of liver abscesses.
Patients And Methods:
Non-random, prospective study of nine patients with pyogenic liver abscess who underwent simple needle aspiration with sonographic guidance.
Results:
In all patients, aspiration identified the etiologic agent. In eight patients (88.9%) the procedure was effective and in the remaining patients, the abscess was finally drained by sonographically guided catheter placement. In five patients, aspiration was successful at the first attempt and only one abscess required more than two attempts. No complications were observed.
Conclusions:
In our experience, needle aspiration with sonographic guidance is safe and effective in the treatment of pyogenic liver abscesses. Use of catheters is reserved for cases of rapid reaccumulation of exudate without general improvement in the patient.
Insights
Needle aspiration guided by ultrasound is a safe and effective treatment for pyogenic liver abscesses. This minimally invasive approach offers a high success rate, reserving catheter drainage for complex cases.
Area of Science:
- Hepatology
- Interventional Radiology
- Infectious Diseases
Background:
- Percutaneous drainage is the standard treatment for liver abscesses.
- Catheter placement, a common technique, carries potential complications.
Purpose of the Study:
- To evaluate the safety and efficacy of needle aspiration for treating pyogenic liver abscesses.
- To compare needle aspiration with traditional catheter drainage.
Main Methods:
- A prospective, non-random study involving nine patients with pyogenic liver abscess.
- Sonographically guided simple needle aspiration was performed on all participants.
Main Results:
- Needle aspiration successfully identified the causative agent in all cases.
- The procedure was effective in 88.9% of patients, with no observed complications.
- Catheter placement was required for only two patients with persistent abscesses.
Conclusions:
- Ultrasound-guided needle aspiration is a safe and effective primary treatment for pyogenic liver abscesses.
- Catheter drainage is reserved for cases with rapid reaccumulation of exudate and lack of clinical improvement.
