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 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.

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.

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.

Ovarian tissue cryopreservation
The French law on bioethics dated August 6 2004 now states the possibility for any person to benefit from a gamete or a germinal tissue collection as well as its preservation. Collection and preservation are planned when the patient’s management may induce a fertility alteration or when the patient’s fertility may be prematurely altered. Young girls who have not reached the age of puberty and who are about to undergo high-dose chemotherapy and/or major radiation therapy for cancer, can benefit from a cryopreservation of their ovarian tissue. It will allow to preserve fertility when these patients have a wish for pregnancy. Once collected, preserved ovarian cortical strips are systematically sent for frozen section to the pathology department in order to be processed for cryopreservation. Later on, when these young women have been healed and wish to become pregnant, the thawing of preserved ovarian cortical strips and the orthotopic autograft can take place. We suggest to collect the anterior cortex from both ovaries, which allows to preserve the two remaining ovaries. Another technique, which is performed by other teams, involves a unilateral oophorectomy for ovarian tissue preservation. A bilateral hemicortical sampling on both ovaries is well accepted by patients and their parents. Indeed, the video does not present an oophorectomy, which is considered as a definitive procedure, but a bilateral sampling which leaves two ovaries in place. The ovaries are reduced in size but are anatomically and functionally healthy.

Laparoscopic enucleation of a cystic tumor of the pancreas in a child
This short video describes the laparoscopic enucleation of a benign congenital excretory cyst of the pancreas in a 13-year-old girl.
No prenatal diagnosis had been envisaged and this teen girl was admitted in an emergency setting, with iterative abdominal pain followed by vomiting and weight loss (3Kg) over the last two months.
The entire work-up allowed to rule out the presence of parenchymal tumor involvement and the perfectly regular isolated and apparently normal nature of a cyst situated on the posterior aspect of the pancreatic head, which is totally separate from the biliary tract and from the duodenum.
In these conditions, the diagnosis of Frantz tumor was ruled out and the most probable hypothesis was that of a congenital cystic pancreatic tumor which had recently increased in size. The specificity of the technique used consisted in a pancreatic detachment using a Kocher’s maneuver. The posterior aspect of the pancreatic head was then detached in order to "plicate" or fold the pancreas upon itself.
Once turned over 180 degrees to the left, the posterior aspect of the pancreatic head was perfectly exposed. In addition, after puncture of the cyst, the clear fluid content of the cyst was replaced by a blue dye in order to perfectly identify it through a thin layer of pancreatic parenchyma.
The cyst’s enucleation was subsequently facilitated. No adhesion impaired its detachment from the remainder of the pancreatic tissue. Since the pericystic area was preserved, the risk of secondary pancreatic fistula was prevented, especially because the cyst had been previously opacified, which allowed to rule out any potential communication with the excretory ducts of the pancreas.

Laparoscopic management of a catecholamine-secreting paraganglioma in a 15-year-old boy
We report the case of the surgical removal of a paravesical paraganglioma located on the right vesicoureteric junction in a 15-year-old boy who was screened positive for SDHB gene mutation, which his father suffers from. Indeed, his dad died of a metastatic paraganglioma, notably including bone and cerebral metastases.
The patient has been complaining of major headaches for some time, which were triggered off during urination to the point that he held in urine as long as possible during daytime in order to avoid urinating, and this seemed to be immediately related to the onset of severe headaches.
The tumor location allowed to correctly understand the phenomenon intraoperatively since every bladder mobilization would induce abrupt bouts of high blood pressure.
Resting blood pressure did not evidence any particular anomaly. However, there were high fluctuations in blood pressure, notably when headaches were reported. The tumor was located exactly at the vesicoureteric junction. It necessitated the resection of the lower ureter and the placement of a vesical patch.
Complete surgical resection allowed to eliminate all symptoms. The patient’s clinical and biological work-up is strictly normal more than one year after the intervention.
The resection was performed without paying attention to the potential difficulties related to the type of reconstructive surgery which entailed. Reconstruction of the vesicoureteric junction was achieved without any major problem on a slightly reduced bladder. A minimal vesicoureteric reimplantation was performed according to the Lich-Gregoir technique, with bladder closure onto a vesical drain and a vesicoureteric double J catheter.
Immediate outcomes were uneventful and control performed more than one year postoperatively testified to the absence of tumor recurrence and to the very good functioning of the vesicoureteric junction.

Laparoscopic management of a pediatric bronchogenic cyst in a 6-year-old boy
We report the case of a 6-year-old boy who presented with an infectious bronchopulmonary episode during which a plain anterior chest X-ray was performed. The X-ray showed an opacity at the right apex. A thoracic CT-scan allowed to demonstrate the presence of a right superior and posterior mediastinal cystic structure, which could be either a non-communicating cystic duplication of the esophagus, or a bronchogenic cyst.
The 3D CT-scan image modeling analysis allowed the surgeon to become familiar with a benign superior mediastinal cystic tumor including its surrounding anatomical structures. The tumor was immediately found above the arch of the azygos vein laterally to the superior vena cava and to the right phrenic nerve, and anteriorly to the right vagus nerve.
The resection was performed thoracoscopically, without any difficulty after a small opening of the mediastinal pleura in order to provide direct access to the paramedian cyst.
Pathological findings demonstrated the presence of a bronchogenic cyst without any communication with the airway tree or the esophagus. Postoperative outcomes were uneventful and the patient was rapidly discharged from hospital.

Hybrid lung malformation with intralobar pulmonary sequestration and congenital cystic adenomatoid malformation (CCAM): thoracoscopic left lower lobectomy (LLL)
This is the case of an infant presenting with a hybrid left lower lung malformation with intralobar pulmonary sequestration and congenital cystic adenomatoid malformation (CCAM).
The systemic arterial vascularization of the sequestration originated from the thoracic aorta. The infant was 8 months old when the thoracoscopic procedure was performed. Prenatal diagnosis helped to identify the uncomplicated lung malformation. A CT-scan was performed when the patient was 6 months old before surgery was scheduled. The surgical intervention, a left lower lobectomy, was immediately preceded by a bronchial endoscopy in order to control the anatomy, the good health of the airway tree, and to place a blocker in the left main bronchus. The first operative step consisted in a ligation-division of the systemic artery as close to the diaphragm as possible. The second operative step consisted in a conventional left lower lobectomy with primary treatment of pulmonary arteries, veins, and bronchi.

Laparoscopic right ureterovesical reimplantation according to Lich-Gregoir
In 2010, François Varlet from Saint Etienne, France, proposed the laparoscopic extravesical transperitoneal approach according to the Lich-Gregoir technique for the treatment of vesicoureteral reflux in children. If the position of the ureterovesical junction is not ectopic, and by avoiding megaureters, this technique is safe with success rates similar to the open technique. Discussions remain as to a bilateral simultaneous approach, which could lead to bladder dysfunction.

Laparoscopic management of a left diaphragmatic hernia in a newborn
Laparoscopic treatment of delayed diaphragmatic hernias in children has been described in 1995 by Klaas Bax and David Van der Zee. Since 2001, we managed to convince the community of pediatric surgeons that it was probably easier to choose a thoracoscopic approach. In some particular conditions, newborns with a congenital diaphragmatic hernia could be treated by thoracoscopy. Until now, more than 400 newborns have been operated on by thoracoscopy to treat a diaphragmatic hernia. Guidelines to specify the appropriate group of newborns for this approach remain discussed in the literature.

Laparoscopic transperitoneal nephrectomy for nephroblastoma
Laparoscopy may be suggested to manage total nephrectomy in specific cases of Wilms’ tumor in children.
Minimal access surgery in pediatric oncology should remain extremely prudent. Some tumors can readily be treated laparoscopically since there is no risk of seeding. On the contrary, in case of seeding, the prognosis would be endangered during surgery for Wilms’ tumor.
Consequently, the decision as to whether or not choose laparoscopy should absolutely be discussed.
Indications for laparoscopic nephrectomy involve tumors treated according to the SIOP treatment guidelines, including primary chemotherapy.
Laparoscopy is mostly decided upon in the presence of a stage I tumor, more rarely in the presence of a stage II tumor without distant metastasis and without tumor thrombus of the renal vein and/or of the vena cava.
Patients with a bilateral tumor are excluded from such therapeutic strategy. Therefore, they will be offered an open nephron-sparing surgery.
Contraindications to laparoscopy include massive post-chemotherapy residual tumor sizes and tumors located proximal to the hilum, since the risk of injuring the tumor during the primary vascular dissection is high.
