Minimally invasive surgery for pediatric solid neoplasms.
The role of minimally invasive surgery (MIS) in children with solid neoplasms is slowly evolving. MIS appears to be an ideal way to obtain diagnostic information (i.e., tissue biopsy) in children with solid neoplasms, but its role as an ablative/curative technique is controversial. We examined the safety, reliability, and outcome of decisions made on the basis of MIS performed in children with solid neoplasms. A total of 28 children (19 boys and nine girls; age range, 14 months to 17 years) with solid neoplasms underwent 29 MIS procedures between July 1, 2000 and June 30, 2002. Complications, biopsy results, and outcomes were reviewed. Successful ablation via MIS was defined as clear microscopic margins on permanent pathology and no evidence of remnant disease on follow-up diagnostic radiological examination. There were 20 thoracoscopic and nine laparoscopic procedures. Laparoscopy included purely diagnostic without tissue biopsy or simply determination of resectability (two), incisional biopsy (two), and excisional biopsy (five; two adrenalectomy and three oophorectomy). Thoracoscopy included 15 lung biopsies and five biopsies of mediastinal masses. Diagnostic accuracy was 100 per cent in all cases. MIS as an ablative technique was successful in 10 of 10 cases. No children were found retrospectively to have been inadequately treated via MIS. We conclude that MIS can be used safely and successfully to diagnose children with suspicious solid neoplasms. Furthermore MIS may have a role as an ablative/curative technique in carefully selected circumstances.
