Abdominal ascites is a common problem in general surgery. The causes include parasitic diseases, tuberculosis, malignancies, hypoalbuminemia, abdominal inflammatory diseases, and peritonitis. Eosinophilic gastroenteritis (EG) has also been reported to be an infrequent cause. To our knowledge, most instances of abdominal ascites from EG have occurred in adults and been reported by physicians or gastroenterologists. Herein, we report a small series of children who presented with eosinophilic ascites from a surgeon’s perspective.

Five children with EG (male: 3; female: 2) were selected for review of medical data and diagnostic reports.

The patients typically presented with intermittent abdominal pain (n = 5), diarrhea and nausea (n = 2), abdominal distension (n = 2), fever (n = 2), and histories of allergic disease (n = 3). Peripheral eosinophilia was regularly noted, three children showing elevated IgE levels. Abdominal ultrasound and CT performed in each instance demonstrated abdominal ascites. Surgical intervention was elected in two patients. Dietary control and a methylprednisolone regimen were then instituted in all children, followed by full clinical remissions. After a regular follow-up, all patients are doing well.

Surgeons should be aware of EG as a rare cause of ascites, even in a pediatric population and especially in children with strong histories of allergic diseases, peripheral blood eosinophilia, and/or family histories of EG. It is important to avoid unnecessary surgical intervention, because dietary control and methylprednisolone treatment are effective remedies.
