[Primary peritonitis]
Insights
Primary peritonitis, a serious abdominal emergency in children, is most common in those aged four to eight. Mortality is higher in infants, emphasizing the need for prompt diagnosis and treatment.
Area of Science:
- Pediatric Surgery
- Infectious Diseases
- Critical Care Medicine
Context:
- Primary peritonitis represents 1-2% of pediatric abdominal emergencies.
- It is a significant cause of diffuse peritoneal sepsis (15%) in children.
- The condition predominantly affects infants and children aged 4-8 years, with a female predominance except in neonates.
Purpose:
- To review the epidemiology, etiology, and clinical presentation of primary peritonitis in children.
- To highlight risk factors and associated conditions.
- To discuss the spectrum of causative organisms and their implications.
Summary:
- Primary peritonitis incidence is higher in children with nephrotic syndrome, cirrhosis with ascites, and immunologic deficiencies.
- Common causative organisms include Staphylococcus and gram-negative bacteria.
- Mortality rates are approximately 50% in infants, decreasing to 10-15% in older children.
Impact:
- Understanding the epidemiology and risk factors can guide preventative strategies.
- Recognizing increased incidence in specific pediatric populations aids early diagnosis.
- Knowledge of common pathogens informs appropriate antibiotic selection and management, potentially reducing mortality.
Abstract:
Primary peritonitis accounts for 1 to 2 per cent of all paediatric abdominal emergencies and for about 15 per cent of diffuse peritoneal sepsis. The condition is still mainly seen in infants and in mid-childhood years, Most frequently in children four to eight years of age, with females outnumbering the males except among neonates where the males predominate. The mortality rate is about 50 per cent for infants, but drops to 10 to 15 per cent in older children. The origin of the infecting organism may be a haematogenous spread or ascension through the female genital tract, but transdiaphragmatic lymphatics and transmural migration through the gut wall may also be possible sources. The incidence of primary peritonitis is increased in children with nephrotic syndrome, postnecrotic cirrhosis with ascites and immunologic deficiency. Practically all kinds of pathogenic organisms are found, but a relative increase in staphylococcal and gram-negative infections has been noted.
