Robotic-assisted laparoscopic surgery for pediatric tumors: a bicenter experience

Abstract

Mini-invasive surgery is more and more integrated in pediatric surgery. The robotic-assisted surgery brought new advantages from which the patient and the surgeon could benefit compared to laparoscopy. Its use in oncological surgery is still controversial. 12 robotic-assisted tumor resections with the da Vinci Surgical Robot (Intuitive Surgical, Sunnyvale, CA) were attempted in 11 children (mean age 7.65 years; age range 0.75-16.75 years; mean weight 30.3 kg; weight range 8.6-62 kg) in two centers. Mean total operative time was 145 min (range 72-263 min). 1 procedure (8.3%) was converted. The pathology included renal tumors (n = 2; one nephroblastoma, one metanephric adenoma), adrenal tumors (n = 9; three neuroblastomas, two pheochromocytomas, two adrenocortical adenomas, one cystic lymphangioma, one paraganglioma) and a pancreatic tumor (n = 1; one pancreatic cyst). 4 tumors (33.3%) were malignant. Every patient underwent a R0 resection. 1 child (8.3%) developed a post operative complication. Mean length of hospitalization was 3.0 days (range 2-5 days). Followup averaged 3.3 years with no recurrence. All children are alive. Robot-assisted MIS seems to be safe and feasible in pediatric tumors. The oncological surgical principles were respected in our series with low morbi/mortality and good long-term results. Robotic surgery and its technical advantages bring potential benefits for children with cancer. It has a role to play in pediatric oncological surgery but its place and indications still need to be better defined.
