Laparoscopic Resection of Pancreatic Tumors in Children: Results of a Multicentric Survey.

OBJECTIVE

This study aimed to report the results of a multicentric survey about laparoscopic treatment of pancreatic tumors in children.

METHODS

The data of patients operated using minimally invasive surgery (MIS) for a pancreatic tumor in 5 International centers of Pediatric Surgery in the last 5 years were retrospectively reviewed. We recorded data relating to the clinical presentation, diagnostic evaluation, surgical technique, and outcome.

RESULTS

Fifteen patients (average age 2.2 years) were identified. The most common symptoms at presentation were related to the hypoglycemic hyperinsulinism, followed by abdominal pain and vomiting. Tumor types were insulinoma (n = 4), congenital hyperinsulinism of infancy (CHI) diffuse type (n = 3), CHI focal type (n = 3), solid pseudopapillary tumor (n = 2), and cystic malformation (n = 3). The diagnostic assessment was completed using ultrasound associated with computed tomography (CT) scan in all centers; 18FDOPA positron emission tomography in combination with CT was adopted in 2 centers. The MIS procedures performed were as follows: tumor enucleation (n = 4), distal pancreatectomy (n = 8), subtotal pancreatectomy (n = 2), and pancreatico-jejunostomy (n = 1). Average operative time was 110 minutes. As for postoperative complications, we recorded 1 persistent hypoglycemia, requiring redo-surgery (IIIb Clavien-Dindo) and 1 thrombosis of splenic vein, not requiring any treatment (I Clavien-Dindo).

CONCLUSIONS

Laparoscopic resection can be considered a safe and effective treatment with minimal morbidity and excellent outcomes for most pediatric pancreatic tumors. Suspension of the stomach with a transparietal stitch and use of new hemostatic devices as Starion TLS3 or Ligasure are key factors for the success of the procedure. A long-term follow-up is mandatory in these patients to evaluate postoperative complications and long-term outcome.
