Laparoscopic Excision of a Large Intra-abdominal Cystic Lymphangioma in a Six-Month-Old Infant

Lymphatic malformation is a rare vascular anomaly caused by abnormal lymphatic system development during embryogenesis. Intra-abdominal lymphatic malformations are uncommon in children, and surgical excision is considered the gold standard for treatment. However, few reports of minimally invasive laparoscopic approaches have been documented. This case report presents a six-month-old infant with a large intra-abdominal cystic lymphangioma, diagnosed prenatally and treated laparoscopically. The lesion was excised en bloc using low-impact laparoscopy, with an uneventful intraoperative and postoperative course. This case highlights the feasibility and safety of laparoscopic excision in young patients, even for large masses. Further studies are needed to establish the role of minimally invasive surgery in pediatric patients with large intra-abdominal lymphatic malformations.
