Thoracoscopy for voluminous left thoracic neuroblastoma in a 2-year-old girl
Video-assisted oncological surgery should be performed in strict compliance with surgical oncology requisites: complete excision, no risk of cancer cell dissemination, and no additional operative risks. Radical surgery requirements must be respected and adjacent organs must be preserved. Our team contributed to research articles on neurogenic tumor surgery, published in international medical journals in 2007 (J Pediatr Surg, 2007; 42 (10): 1725-8 and J Laparoendosc Adv Surg Tech A 2007; 17 (6): 825-9).
Our case study further demonstrates that the thoracoscopic resection of neurogenic tumors perfectly meets oncological surgery requirements, offering the parietal benefits of minimally invasive surgery. A magnified operative field is a major asset because it allows performing surgery safely. It is now possible to gain a perfect knowledge of the patient and tumor anatomy preoperatively by using a 3D modeling tool and preoperative CT-scan images of the patient.

Subtotal laparoscopic splenectomy for hemolytic disorders in a 5-year-old girl
In case of hemolytic disease, subtotal splenectomy is an alternative to total splenectomy, the efficacy of which has been evidenced in the literature (Inter J Surg 2010;8:48-51). This procedure is particularly relevant in young children as it precludes risks of infection related to total splenectomy. Subtotal splenectomy should reduce the size of the splenic parenchyma by 80% in order to prevent recurrence and completion surgery in the short term. In 2008, we had already reported a first multicentric study on subtotal splenectomy (Surg Endosc 2008;22:45-9).
Technically, it is interesting to have access to an inconstant artery draining the superior pole of the spleen, which is then left in place (Surg Endosc 2006;21:1678). When this artery is not present, the superior pole of the spleen will be preserved as it is vascularized by one or two short vessels of the gastrosplenic omentum.

Pheochromocytoma: laparoscopic right adrenalectomy in a child
In the context of major headaches in a 9-year-old patient whose brother had been operated on for pheochromocytoma, a right adrenal pheochromocytoma with severe arterial hypertension was found.
The given video aims to demonstrate the usefulness of performing a 3D reconstruction of the tumor (using Visible Patient™ 3D reconstruction tool). It is essential to have precise preoperative information and work out a surgical strategy taking into account observed anatomical anomalies, since tumor and/or vascular anatomy may have numerous variations in case of pheochromocytomas.
A reconstruction model can be easily manipulated on a touch screen. It can be oriented in such a way that the angle of view changes allowing for a better understanding of the anatomy, so that an approach to vessels or neighboring organs is easily decided upon. Additionally, the option of adding or deleting this or that anatomical element allows for a simplified visual approach, which usually represents a potential difficulty during dissection.
Finally, the 3D reconstruction of this patient perfectly corresponds to her real anatomy. Thanks to a mere scanning based on the reconstruction, the vascularization mode of the tumor as well as the existence of a hidden part of healthy tissue can be verified.

Laparoscopic partial nephrectomy on non-functional, symptomatic right lower pole of the kidney
In this video, we present the case of a 13-year-old girl presenting with a complicated urological anomaly discovered very late. The lower part of her right kidney is dysplastic (or destroyed) with pseudocystic pyelocalyceal cavities filled with stones and cloudy urine. The first hypothesis is that we are dealing with a true renal duplicity with a destroyed non-functional inferior pole. In this case, there is one ureter per kidney pole. As a result, polar ureteronephrectomy does not cause any potential vascular problems.
In this case, thanks to 3D reconstruction (Visible Patient™, a spinoff of IRCAD), it is clear that there is no kidney duplicity, but a pyelic bifurcation. It means that we should manage the only ureter, which drains the superior and inferior pelvis. For that reason, the placement of a double J catheter is essential prior to partial nephrectomy. This catheter should be pulled up until the superior pelvis.
Tridimensional reconstruction of the CT-scan images of a patient with a malformation is extremely helpful to better understand the original and unique anatomy of the patient and to determine a tailored operative strategy.
This video demonstrates a laparoscopic partial nephrectomy on non-functional, symptomatic right lower pole of the kidney in a 13-year-old girl as an outpatient surgery.
