[Ultrasound-guided puncture. Modern treatment of liver abscess]
1Département de Gastro-Entérologie, Clinique Résidence du Parc, Marseille.
Abstract:
The treatment of liver abscesses has benefitted from progress in imaging, particularly ultrasonography which allows simple and reliable aspiration and drainage. A series of 32 cases is reported, consisting of 29 pyogenic abscesses and 3 amoebic abscesses. Eighty-one per cent of patients were cured by aspiration and/or drainage, while 19% of patients had to be operated. The mean hospital stay was 11 days. Failures of ultrasound-guided aspiration are essentially due to multifocal abscesses caused by multiple organisms.
Insights
Ultrasonography enables effective liver abscess treatment through aspiration and drainage. This minimally invasive approach successfully treated 81% of patients, reducing the need for surgery.
Area of Science:
- Medical Imaging
- Gastroenterology
- Surgical Procedures
Background:
- Liver abscesses require effective treatment strategies.
- Advancements in medical imaging have improved diagnostic and therapeutic capabilities.
- Ultrasonography offers a minimally invasive option for liver abscess management.
Purpose of the Study:
- To evaluate the efficacy of ultrasonography-guided aspiration and/or drainage for liver abscess treatment.
- To report outcomes in a series of patients with pyogenic and amoebic liver abscesses.
Main Methods:
- Retrospective case series of 32 patients with liver abscesses.
- Utilized ultrasonography for diagnosis, aspiration, and drainage procedures.
- Classified abscesses into pyogenic and amoebic types.
Main Results:
- 81% of patients achieved cure with aspiration and/or drainage.
- 19% of patients required surgical intervention.
- Mean hospital stay was 11 days.
- Ultrasound-guided aspiration failure was linked to multifocal abscesses and polymicrobial infections.
Conclusions:
- Ultrasonography-guided aspiration and drainage are highly effective for liver abscesses.
- Minimally invasive procedures can significantly reduce the need for surgery.
- Multifocal and polymicrobial abscesses present challenges for percutaneous treatment.
