    Abstract:
    BACKGROUND: Abdominal Cystic lymphangiomas (ACL) are uncommon benign masses usually presented during infancy. Although extremely rare, they may cause complications; therefore, the recommended therapy is surgical excision. The purpose of this study is to report our experience with the diagnosis and surgical treatment of ACL in pediatric population. MATERIAL AND METHODS: From January 1994 to December 2009, 10 patients (6 females; 4 males) with diagnostic confirmation of ACL were retrospectively included in study. Children's age ranged between 9 months and 8 years (mean age at diagnosis was 2.5 years). Clinical presentation, cyst location, imaging studies employed, surgical approach and pathologic features were analyzed. RESULTS: The most common symptom was abdominal pain but three cases were incidentally detected. One case had presented with acute abdomen after traumatic haemorrhage of the tumor. All patients were diagnosed with ultrasonography as first-line radiological study. MRI was used in last three cases. At surgery, concomitant bowel resection was necessary in 3 children. Location of the lesion (omentum, mesentery) did not influence the outcome but surgery was more difficult (operative time over three hours) in patients with lymphangioma affecting mesentery of the jejunum. Mean hospital stay after surgery was 6.7 days. Mean follow-up was 5.1 years. No recurrence of the cystic lymphangioma was noticed during follow-up. One case developed an intestinal occlusion due to bowel adhesions 1 year after surgery. CONCLUSIONS: ACL usually affect infants and young children and may present with spectrum of symptoms from an incidental finding to an acute life-threatening abdominal obstruction. Complete excision of the tumor is a safe and effective method in the management of ACL in pediatric population. Surgery is mandatory to avoid potential complications.
