Laparoscopic repair of a congenital diaphragmatic hernia (CDH)
Eligibility criteria for the thoracoscopic approach in case of a congenital diaphragmatic hernia (CDH) in infants were jointly addressed at the ESPES/IPEG-ESPU Masterclass in March 2017 held at IRCAD, and also published on WeBSurg.
This video aims to show a series of technical details in case of thoracoscopy for CDH grade B according to the currently accepted international classification. At the beginning of the procedure, short intrathoracic low pressure carbon dioxide insufflation at 4mmHg and 1.5 Liter per minute was performed during hernia reduction. The posterior diaphragmatic border was then freed and a diaphragmatic suture was performed using non-absorbable separate 2/0 stitches. A GoreTex DualMesh® patch was used to complete the external suturing of the diaphragm and to achieve fixation stitches.

Inanimate model to train for the thoracoscopic repair of all varieties of left congenital diaphragmatic hernia (CDH)
We present a new low-cost model designed for training skills and strategies for the thoracoscopic repair of left congenital diaphragmatic defects. We will present guidelines to make this type of models, the educational strategy that we use in our advanced training models, the defects that can be trained, and the scope of this model. Advanced training, learning tips and tricks from experts, and the use of innovative ideas from other authors used in our model are outlined. This educational tool was developed for pediatric surgeons requiring advanced training. It reinforces the concept of advanced and continuous training, in a safe environment, and it is assisted by experienced surgeons. This model shows a scenario where dimensions and anatomical repairs are carefully preserved.
We share our vision of continuous endosurgical education to encourage all enthusiastic surgeons to train in safe and controlled environments.
Materials and methods: The model consists in a plastic 3D printed left rib cage, extracted from a 6-month-old baby CT-scan combined with simulated mediastinal structures, diaphragm, bowel, lung, and spleen made of latex, silicone, and polyester sponge respectively. A self-adhesive film is used as parietal pleura. A removable part (spare part) represents the last three ribs where the diaphragm is partially inserted, and a base as the upper abdomen is assembled to the left rib cage (ribs 1 to 9). Abdominal viscera (plastic or animal) are placed in this base. The cost of materials is 150 US$.
The model is meant to simulate the most frequent diaphragmatic defects such as type A, B, and C, with or without sac. However, other rare defects can also be simulated. Live animal tissues such as diaphragm or intestine also can be used, as it was already published by other authors. However, the main characteristic of this model is to be inanimate, portable, and easily reloadable to be reused.
The video shows a junior surgeon in his advanced training process. In the model, we perform the reduction of the viscera slid to the thorax. In this case, it is the rabbit intestine, but we usually use latex simulated intestine. The spleen is completely synthetic and bleeds if the instruments damage it during the reduction.
We use 3mm regular instruments. The repair of the defect is made with separate stitches of 2/0 or 3/0 braided polyester as usual, and we encourage trainees to practice the intracorporeal sliding knot and running suture. We collect the performance data in a specially prepared form and carry out the debriefing.
Conclusions: With this model, we can reinforce the concept of low cost, but with a high precision environment simulation, included within a standardized training program in minimally invasive neonatal surgery. We believe that it is a very useful tool. In addition, this type of models allows the use of new surgical techniques, tips and tricks given by experienced surgeons who assist in the training process.

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.

Incidental finding of a voluminous bronchogenic cyst in a 13-year-old child
This rare case of a giant bronchogenic cyst in the lower right hemithorax allows to provide the following tips: patient positioning and port placement should allow for a 180-degree reversal of the screen and free movement of the surgical team; use of a LigaSure™ vessel-sealing device used as a dissection instrument in lung surgery is helpful but does not guarantee perfect aerostasis, which should be controlled by taking enough time at the end of the procedure when reventilating an excluded lobe intraoperatively; along with low intrathoracic carbon dioxide insufflation, the use of a blocker in pediatric thoracoscopic surgery is an unconditional factor, which contributes to a satisfactory operating field.

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.
