Laparoscopic ligation of middle sacral artery and dissection of sacrococcygeal teratoma to decrease intraoperative hemorrhagic risk
Sacrococcygeal teratomas are the most common teratomas presenting at birth. Life-threatening bleeding is a major complication during tumor excision in children. In this video, we demonstrate our technique for the laparoscopic division of the middle sacral artery during dissection of sacrococcygeal teratomas in two pediatric patients.
Two female infants diagnosed with type IV and type III sacrococcygeal teratomas underwent preoperative evaluation in the postnatal period. The first patient was an 18-month-old female patient who presented with a metastatic type IV teratoma resected after neoadjuvant therapy. The second patient was a 6-day-old female infant with a prenatal diagnosis of cystic type III teratoma. Using laparoscopy in both patients, the presacral space was reached by opening the peritoneal reflection with blunt dissection and the middle sacral artery was identified. It was then carefully isolated and divided with a 5mm LigaSure™ vessel-sealing device. The pelvic components of the tumors were partially dissected using laparoscopy. The first patient’s tumor resection was completed using a posterior sagittal approach and the second patient required a standard Chevron incision.
Both patients underwent a successful laparoscopic division of the middle sacral artery and resection of the sacrococcygeal teratomas without complications. As a result, laparoscopic middle sacral artery division before sacrococcygeal teratoma excision offers a safe approach which can reduce the risk of hemorrhage during surgery.

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.

Laparoscopic Mitrofanoff continent diversion in children
Neobladder surgery is often complex. It is readily proposed lately in a child’s life when he agrees to undergo a fairly heavy surgical operation, which will allow him to acquire a social body cleanliness. The poor vesical volume capacity may necessitate either a chemical enlargement with iterative Botox injections into the detrusor muscle, or a vesical enlargement surgery using a bowel segment.
Self-catheterization using natural orifices is often particularly uneasy in boys or in obese or handicapped patients. This mandates to leave an open vesicourethral neck, which however does not prevent potential urinary leaks. This mode of vesical voiding has an alternative, namely Mitrofanoff continent diversion using the appendix.
This procedure was described in 1980. The vesico-appendiceal junction is fashioned by means of an anatomical anti-reflux mechanism. The skin approximation onto the anterior abdominal wall can be performed either in the umbilicus, or in the inguinal region depending on different decisional criteria.
This procedure can now be envisaged laparoscopically. It is a demanding intervention, which requires advanced skills.

The vascular hitch: a simpler procedure for vascular pyeloureteral junction obstruction (PUJO)
Ureteropelvic junction obstruction may occur in about 10% of cases, the origin of which is not an intrinsic organic obstruction in this transitional area between the renal pelvis and the ureter, but it is rather secondary to an extrinsic obstruction, related to the presence of aberrant lower pole vessels.
It is an intermittent ureteropelvic junction obstruction syndrome, which is usually diagnosed late and in which renal function is most often preserved. The operating technique was already described more than 60 years ago. It is a simple technique.
The greatest difficulty is not technical but lies in the indication which must be relevant. The main difficulty is to preoperatively and intraoperatively evaluate either the totally extrinsic nature or conversely the mixed nature of the obstruction, which in that case requires a pyeloplasty according to Anderson-Hynes with division of the ureterovesical junction posteriorly to the vessels and reconstruction of the ureteropelvic junction once enlarged, anteriorly to the lower pole vessels.
