Insights
Non-operative management for pediatric liver abscesses showed healing in 37% of cases. Solitary left-sided liver abscesses in children often require early surgical drainage for successful outcomes.
Area of Science:
- Pediatric Gastroenterology
- Hepatology
- Infectious Diseases
Background:
- Liver abscesses in children are uncommon but can lead to serious complications.
- Both pyogenic and amoebic infections can cause liver abscesses.
- Non-operative management is a common initial approach.
Purpose of the Study:
- To evaluate the outcomes of non-operative management for pediatric liver abscesses.
- To identify factors associated with successful non-operative treatment.
- To determine the optimal management strategy for different types of liver abscesses.
Main Methods:
- Retrospective review of 124 children with liver abscesses treated between 1974 and 1990.
- Analysis of abscess location, type (pyogenic vs. amoebic), and management approach.
- Clinical and ultrasonographic follow-up to assess treatment success.
Main Results:
- Overall, 37% of children treated non-operatively achieved healing.
- Multiple abscesses had a higher response rate (60%) to non-operative management.
- Solitary left-sided liver abscesses frequently required drainage (14/16) and had a higher risk of rupture.
Conclusions:
- Non-operative management can be successful for pediatric liver abscesses, particularly multiple ones.
- Solitary left-sided liver abscesses in children warrant early surgical intervention due to higher complication rates.
- Prompt diagnosis and appropriate management are crucial for favorable outcomes in pediatric liver abscesses.
Abstract:
A total of 124 children aged less than 14 years with a liver abscess were seen in a 16-year period (1974-1990) and treated by non-operative initial management. Of the abscesses 98 occurred in the right liver and 26 in the left. The abscesses were solitary in 93 patients. Overall, 77 of the solitary and 21 of the multiple abscesses were confined to the right liver. In 78 of the right-sided and 20 of the left-sided abscesses the infection was primarily pyogenic in nature with Staphylococcus aureus being the usual organism cultured. The remainder were of amoebic origin. Clinical features were similar in patients with amoebic and pyogenic abscesses. Clinical and ultrasonographic follow-up demonstrated successful non-operative management and healing in 37 per cent of all patients submitted to an initial protocol of medical supportive care and antibiotic therapy. Of the multiple abscesses 60 per cent responded to non-operative management. Fourteen of the 16 solitary left-sided liver abscesses required drainage and three left-sided abscesses ruptured before drainage. Patients with a solitary left-sided abscess warrant early operative intervention.
