Abstract:
Laparoscopy for the resection of liver masses in children has remained undeveloped despite the wide acceptance of laparoscopy in the field of pediatric surgery. The authors report a case of nonanatomical laparoscopic hepatic resection of a large mesenchymal hamartoma in a 2-year-old boy. The procedure was performed using an innovative approach with a combination of different technologies that allowed for a safe and precise resection. This case demonstrates the feasibility of a nonanatomical laparoscopic hepatic resection, even for very large tumors. Both technical expertise and use of novel technologies are necessary to ensure a precise and controlled resection.
