A prospective study of minimally invasive techniques in pediatric surgical oncology: preliminary report

Abstract

MIS was practical in every fourth patient in our experience so far. It proved to be an excellent approach in diagnostic interventions and tumor biopsies, whereas efficacy is limited in tumor resections. Further factors (tumor recurrence, trocar site recurrence, tumor growth, and dissemination after CO(2) insufflation) have to be evaluated. Our data encourage the continuation of the study.

Role of diagnostic and ablative minimally invasive surgery for pediatric malignancies

“…The conversion rate was higher than one-third in both laparoscopies and thoracoscopies. This corresponds with the results of our previous preliminary report 13 and indicates that problems due to limited visibility may not be overcome with increasing experience. However, we found minimally invasive tumor resection to be safe.…”

“…3,4,23 The spectrum of malignancies included the whole range of pediatric abdominal, retroperitoneal, and thoracic tumors, such as neuroblastoma, nephroblastoma, hepatoblastoma, rhabdomyosarcoma, teratoma, lymphoma, and numerous others. 3,4,8,13,[23][24][25][26] The conversion rate was less than 5%, the diagnostic accuracy of biopsies was up to 100%, and there were no major intra-or postoperative complications. 13,23,24,26 Our data confirmed an excellent feasibility of minimally invasive biopsy with an accuracy of 98% and a conversion rate of 15% in laparoscopic and 7% in thoracoscopic biopsies.…”

Bleeding during laparoscopic biopsy of a neuroblastoma necessitated 1 conversion.…”

“…4,10,11 However, minimally invasive resection of solid tumors in children is not yet generally accepted, and its feasibility remains to be determined. 4,12,13 The aim of the present study was to evaluate the diagnostic and ablative role of MIS in a consecutive series of children with malignancies.…”

Endosurgery in Diagnosis of Tumor Diseases in Children

“…В 6 случаях потребовалась конверсия в связи с воз-никшими осложнениями. Авторы пришли к выводу, что лапароскопическая биопсия является надеж-ным диагностическим инструментом при опухоле-вом поражении брюшной полости у детей [16]. А на основании оценки пятилетнего опыта применения эндохирургии у детей со злокачественными ново-образованиями установлено, что этот метод должен быть включен в комплекс диагностических методов обследования при опухолевом процессе, так как позволяет не только визуализировать опухоль, но и выполнить биопсию, оценить распространенность процесса [15].…”
