AN ASSESSMENT OF OUTCOMES OF HEPATIC ABSCESS MANAGED BY PERCUTANEOUS NEEDLE ASPIRATION VERSUS PERCUTANEOUS CATHETER DRAINAGE - A COMPARITIVE STUDY

Résumé fourni par la source

Introduction: Liver abscesses are localized collections of pus in the liver, commonly caused by infections such as bacteria, fungi, or parasites. The most frequent causative organisms include Klebsiella pneumoniae and Escherichia coli, while amoebic liver abscesses are less common. Without proper treatment, the mortality rate can be high, but early detection and appropriate drainage techniques, such as percutaneous needle aspiration (PNA) and percutaneous catheter drainage (PCD), can improve outcomes. PCD, especially when combined with antibiotics, is generally preferred for its higher success rates and lower risks. Aim And Objectives: The aim of this study was to evaluate the therapeutic efficacy of ultrasoundguided percutaneous needle aspiration (PNA) and ultrasound-guided indwelling Pigtail/Malecot catheter drainage (PCD) in the treatment of amoebic and pyogenic liver abscesses. Objectives included comparing the recurrence rates, complications, duration of hospital stay, and cost of treatment between the two modalities. Methodology: This prospective study was conducted from August 2023 to February 2025 at Rajkiya Medical College, Orai, Jalaun, involving 100 patients diagnosed with liver abscesses. Patients were randomly divided into two groups: Group I received ultrasound-guided PNA, while Group II underwent ultrasound-guided PCD. Both groups were treated with anti-amoebic (metronidazole) and antibiotic therapy. Post-discharge follow-up lasted six months to assess outcomes. Results And Conclusion: The study showed no significant differences between the groups in terms of age, co-morbidities, or hematological parameters. However, Group II, which received PCD, exhibited a lower recurrence rate, fewer complications, and a shorter hospital stay compared to Group I. Both treatments were similarly effective in improving clinical outcomes, with PCD offering a slight advantage in managing larger or more complex abscesses. These findings suggest that PCD may be a more effective treatment modality for certain liver abscess cases.
