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.
