Objective@#To explore the value of Hisense computer-assisted surgical systems (CAS) for precise surgery of pediatric solid pseudopapillary tumor.@*Methods@#A total of 5 cases with pancreatic solid pseudopapi-llary tumor who were admitted at the Affiliated Hospital of Qingdao University from June 2015 to September 2018 were adopting.Upper abdominal 64-slice dynamic enhanced computed tomography (CT) scan was performed.3D models were created by computer-assisted surgery systems.Based on 3D model, surgical planning, preoperative simulated tumor resection, intraoperative assisted guidance were performed.Operation time, intraoperative blood loss volume, blood transfusion rate were analyzed.@*Results@#Hisense CAS three-dimensional reconstruction could clearly show the adjacent relationship between pancreas, tumor and peripheral vascular organs.According to the preoperative virtual resection, pancreatic tumor resection was more accurate.Postoperative pathological results were solid pseudopapillary tumor of the pancreas.Among them, 2 tumors were located in the head of the pancreas, 1 case was located in the pancreatic neck, and 2 cases in the tail of the pancreas.The operation time was 150-360 min, with an average of 279 min.The average intraoperative blood loss was 40 mL, of which the minimum amount of bleeding was 5 mL, and the blood transfusion rate was 40%(2/5 cases). Surgical tumor removal was achieved successfully in 5 cases.All children were followed up for 6 months to 3 years, and no recurrence or metastasis was observed.@*Conclusions@#Three-dimensional reconstruction of computer-assisted surgery system can clearly show the adjacent relationship between tumor and surroun-ding vascular organs, and help to make the best surgical plan before surgery to improve the accuracy and safety of the operation.

RESUMO
Introducción. El tumor sólido pseudopapilar del páncreas (TSP) es un tumor epitelial de baja malignidad que afecta principalmente a mujeres jóvenes y comprende aproximadamente 1-2% de todas las neoplasias de páncreas. Presentamos un caso de este tipo de tumor tratado en el Hospital General de Tijuana en el Servicio de Cirugía Pediátrica, así como una revisión de la literatura. Caso clínico. Se presenta el caso de un paciente femenino de 12 años de edad con la única sintomatología de tumor palpable en epigastrio de crecimiento progresivo. Es diagnosticada con un tumor sólido pseudopapilar localizado en la cola del páncreas y tratada exitosamente con pancreatectomía distal sin esplenectomía. Se egresa a los 3 días de postquirúrgico. Discusión. Se concluye que el TSP es un diagnóstico diferencial ante la presencia de masas a nivel del páncreas, aunque por su rareza no debe ser la primera opción a descartar, especialmente en pacientes pediátricos. La cirugía por sí sola representa el mejor tratamiento para esta entidad patológica, ya que demuestra un nivel de curación excelente, y se debe intentar en todos los casos independientemente del tamaño de la lesión pancreática.
Background: Solid pseudopapillary tumor (SPT) of the pancreas is a low-grade epithelial malignant tumor principally affecting young women and represents ~1-2% of all pancreatic neoplasms. We present a case of this type of tumor treated at the General Hospital of Tijuana in the service of pediatric surgery. We also present a review of the literature. Case: We present the case of a 12-year-old female with symptomatology of a progressively growing palpable tumor in the upper abdomen. She was diagnosed with SPT located in the tail of the pancreas. It was treated successfully with distal pancreatectomy without splenectomy. The patient was discharged on the third post-surgical day. Discussion: SPT is a differential diagnosis with the presence of a mass at the level of the pancreas. Due to its rarity, it is not the first option to rule out, especially in pediatric patients. Surgery alone represents the best treatment for this pathological entity and should be attempted in all cases, independent of the size of the pancreatic lesion.
