Abstract:
Peritoneal inflammation without a discernible intraperitoneal source is referred to as primary peritonitis. Only 2% of pediatric acute abdominal crises are diagnosed preoperatively. Association with other infections is uncommon and is often limited to hepatic and urinary pathogens. Here, we describe a case of primary peritonitis in a one-month-old child who had laparotomy and appendicectomy as per the recommended treatment plan. There were no accompanying hepatic and urinary diseases. In this instance, methicillin-resistant Staphylococcus aureus (MRSA) was the responsible bacteria. The use of linezolid, as per the culture sensitivity report of intraperitoneal pus, ensured a smooth recovery in this case.
Insights
Primary peritonitis, inflammation without a clear source, is rare in children. This case highlights methicillin-resistant Staphylococcus aureus (MRSA) as a cause in an infant, successfully treated with linezolid.
