Abstract: Purpose: This study evaluated the safety and efficiency of laparoscopically treated liver cysts in children. Methods: From September 2001 to July 2004, 34 patients underwent laparoscopic treatment of hydatid cysts of the liver. All patients had chest x-ray, abdominal sonography, and hydatid serology. The different stages of the procedure were the same as in open surgery: puncture, aspiration, injection of scolicidal agent, reaspiration, removal of proligerous membrane, and resection of the dome. Results: The patients'' mean average age was 7 years and 7 months (range, 3-14 years). The number of cysts ranged from 1 to 10 with a diameter of 40 to 150 mm (mean diameter, 65.5 mm). One case had a mesenteric associated hydatid cyst, another splenic hydatid cyst. The average length of hospital stay was 5 days (range, 4-14 days). No per- or postoperative complications were reported. At 12 to 45 months follow-up, no recurrence has been reported. Conclusion: Laparoscopy represents an excellent approach for the treatment of hydatid cyst of the liver in children. [Copyright &y& Elsevier]

Abstract: Renal hydatid disease is rare in children. Open surgery is the traditional method of treatment, but minimally invasive techniques are being increasingly used. Herein, we report our experience with laparoscopic management of renal hydatid cyst in four children via a transperitoneal approach in three cases and a retroperitoneoscopy in one. We conclude that transperitoneal laparoscopy can be offered for the management of hydatid renal cyst associated with other intraperitoneal localizations, whereas the retroperitoneoscopy is limited for the treatment of isolated hydatid renal cysts.

Abstract: An infant with congenital pancreatic cyst with Ivemark II syndrome is reported because it is a rare association. The infant had associated situs inversus, asplenia, and complex congenital heart disease. The pancreatic cyst was successfully managed by cystoduodenostomy because of connection to the biliary tract. The infant succumbed as a result of heart failure at age 2 months. Prognosis depends on the presence of life-threatening malformations. [Copyright &y& Elsevier]

Abstract: Lipoblastoma is a rare, benign, fatty tissue tumor that occurs in childhood. The location of this tumor in the mediastinum and extension to the chest wall is uncommon. We describe a 12-month-old male infant with a mediastinal lipoblastoma discovered because of a chest wall swelling. Computed tomography showed the deep component and fatty content of the lesion suggestive of the diagnosis. Total excision of the mass was carried out. The histologic examination of the lesion confirmed the diagnosis of lipoblastoma. Mediastinal lipoblastoma should be considered among the possible diagnoses of a fatty mediastinal tumor in childhood.
