Background: Mesenteric cysts are rare intraabdominal masses in the paediatric age group with varied presentation, ranging from an asymptomatic mass to acute abdomen. This study reviews ourexperience in the diagnosis and treatment of 17 mesenteric cysts in our centre, with especial reference to acute abdominal symptoms.Patients and Methods: Seventeen patients (age less than 10 years) withmesenteric cysts were managed in our hospital. The age ranged from 15 days to 10 years. Patients were admitted with acute or chronic symptoms. They were evaluated with complete history, clinical examination,blood investigations and radiological investigations (x-ray abdomen erect, ultrasound abdomen (USG) and computed tomography (CT) scan in selected cases) to reach a provisional diagnosis. The diagnosis was proven on laparotomy and histologically confirmed.Results: The main presenting symptoms were abdominal pain or lump. The most common mode of presentation was acute small intestinal obstruction. USG was not conclusive in all. Abdominal CT scanwith intravenous contrast was diagnostic in nine patients. Five patients had volvulus on exploration. Cysts were located in small intestinal mesentery in14 cases and three were in the sigmoid mesentery. Seven patients had complete excision, intestinal resection was required in four and marsupialisation with cauterisation of margins was done in six patients.Histologically, all were lymphangiomatous mesentericcysts. Conclusion: The diagnosis of mesenteric cysts should be kept in mind in any patient presenting with acute abdominal symptoms. Small bowel volvulus with mesenteric cyst constituted a significant numberin children with acute abdominal symptoms. Early diagnosis and treatment yields excellent outcome.
