The laparoscopic approach of neuroblastoma.

Neuroblastoma is one of the most common solid tumors, and the biopsy and excision of this tumor are often required as part of a planned multimodal treatment. In 1995, Holcomb and coworkers first reported endosurgical procedures for the diagnosis and treatment of pediatric malignancies; however, the usefulness of laparoscopic procedures for abdominal neuroblastoma is still unclear. Twenty-five laparoscopic biopsies for advanced abdominal neuroblastoma and nine laparoscopic excisions for localized abdominal neuroblastoma performed at Saitama Children's Medical Center were evaluated. The laparoscopic procedures significantly reduce the time to start postoperative feeding as well as the time to start postoperative chemotherapy and the duration of hospital stay. Also, the blood loss of laparoscopic excision of localized neuroblastoma was significantly little compared with that of open excision. Precise indications of laparoscopic procedure for the diagnosis and treatment of abdominal neuroblastoma provide better prognosis and quality of life for infants and children.
