Possibility for gastro-pancreatoduodenal and pancreatoduodenal surgical resections in children with pancreatic tumors

The article is about the experience in treating of pediatric patients with tumors of the pancreas who have undergone the gastro-pancreatoduodenal resection (GPDR) and pancreatoduodenal resection (PDR) at the Research Institute of Pediatric Oncology and Hematology named after Academician L.A. Durnov with the N.N. Blokhin Russian Cancer Research Center (Moscow, Russia). These kinds of surgical interventions are performed both with local neoplasms of the pancreatic head and with the spread of the tumor process to the duodenum, distal part of the stomach, and parapancreatic tissue. Materials and methods used: 13 GPDR, PDR surgical interventions were performed in children aged 5 to 16 y/o in 2010-2022. The results of treatment of these patients were assessed as satisfactory despite the complications that arose in some patients in the early and late postoperative periods. All patients are alive. GPDR surgical interventions were performed in 6 patients, and PDR in 7. The most frequently verified were solid pseudopapillary tumor of the pancreatic head (in 10 cases), neuroendocrine tumor (in 2 cases) and paraganglioma in a single case. Discussion and conclusions: bleeding from the pancreatic branch of the splenic artery and acute pancreatitis were noted among the early postoperative complications. Recurrent phenomenon of enzyme evasion and syndrome of excessive bacterial growth were revealed in the late postoperative period. Despite the complications arisen all patients are alive without signs of recurrence of the disease. The prognosis for this category of patients with radically performed surgical intervention is favorable.
