Background/aims: The aim of this study was to evaluate the usefulness of 3D-CT simulation in pediatric minimally invasive surgery.Methodology: adenomatoidPreoperative 3D-CT simulation was performed using data from contrast enhancement MDCT and SYNAPSE VINCENT software.The images of 3D CT simulation were installed to iPad, and were used as intra-operative images.From 2011 to 2015, three cases who underwent minimally invasive surgery were enrolled.

(hepatoblastoma (n = 1), Congenital cystic aednomatoid malformation (CCAM) (n = 1) and mediastinal tumor (n = 1)).Results: Case 1: 1y-6m male with hepatoblastoma (PRETEXT I, S5) underwent laparoscopic surgery after the preoperative chemotherapy tenga flip orb (CDDP 4 course).On preoperative 3D-CT simulation, the positional relationship between the lesion, vasculature and bile duct had been described well.And the laparoscopic tumor resection (partial hepatectomy) was lightemupsequences.com safely performed.

Case 2: 11 m female with Congenital Cystic Adenomatoid Malformation (CCAM) underwent thoracoscopy-assisted lobectomy.On preoperative 3D-CT simulation, the positional relation ship between the lesion, vasculature and bronchus had been described.Furthermore, 3D-CT described the aberrant-V2 which was arisen from inferior pulmonary vein to drain the right upper lobe.And the thoracoscopy-assisted resection of right upper lobe was safely performed.

Case 3: 6-years-old male with mediastinal cyst (e.g.bronchogenic cyst) underwent completely-thoracoscopic tumorectomy.On preoperative 3D-CT simulation, the positional relationship among the lesion, bronchi, cardiovascular system, and esophagus.

Conclusions: Preoperative 3D-CT simulation and intraoperative navigation for pediatric minimally invasive surgery were useful and feasible.Keywords: Hepatoblastoma, CCAM, Mediastinal cystic tumor.
