LIVE INTERACTIVE SURGERY: robotic low anterior resection for a local recurrence of rectal cancer
In this live interactive surgery, Dr. Parra-Davila demonstrates a robotic low anterior resection for a local recurrence of transanally excised rectal cancer. The operative technique shown includes a robotic oncological ‘en bloc’ resection and intracorporeal anastomosis. In the patient’s history, an ulcerated villous polyp too large for endoscopic removal was addressed to surgery. Preoperative biopsies had failed to detect malignancy. The surgical procedure consisted in a transanal full-thickness resection including partial TME for lymph node sampling. Since the operative specimen revealed a pT2N1a (1/8) rectal adenocarcinoma, the patient underwent adjuvant radiochemotherapy. The following year, a single hepatic metastasis was resected, complemented by postoperative chemotherapy. After 7 years of uneventful follow-up, an anastomotic recurrence was diagnosed. Following oncologic committee discussion, the patient was advised to undergo 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.

LIVE INTERACTIVE SURGERY: laparoscopic left adrenalectomy: retroperitoneal access
Retroperitoneal adrenalectomy (posterior approach) provides a direct access to the adrenal gland, hence preventing the risk of injury to intraperitoneal organs. The retroperitoneoscopic approach shortens the mean operative time and it is critical in cases of pheochromocytoma. Consequently, it is the recommended treatment for pheochromocytoma. Blood loss and the convalescence period are also shortened with this approach. The surgical principles of retroperitoneal adrenalectomy according to Professor Martin Walz are as follows: ‘en bloc’ resection, start of dissection with the upper pole of kidney, lower pole of the adrenal gland next, control of the main adrenal vein without clips, and morcellation of the gland if necessary in a bag.

Laparoscopic resection of colorectal liver metastasis in segment VII with transthoracic port-site insertion using ultrasonography and augmented reality
We report the case of a laparoscopic resection in a patient presenting with a colorectal liver metastasis in segment VII of the liver, with transthoracic trocar insertion. The patient is placed in a lateral decubitus position. Four ports are introduced. After exploration of the peritoneal cavity and ultrasound examination, the intervention is begun with the control of the hepatic pedicle. The right liver is mobilized. As the position of the scope is not ideal, an improved vision is searched for using simulation tools. The subcostal port allows for an optimal view. The 5mm port is switched to a 12mm port, allowing for the placement of the scope. A 5mm port is then placed transthoracically in order to start the hepatotomy. The hepatotomy is performed under a full pedicular clamping, which takes 20 minutes. Dissection is started 2cm around the lesion. The specimen is placed in a bag and extracted through a slightly enlarged 12mm port. After hemostatic control, the tape around the pedicle is removed. The cavity is extensively cleansed. The pneumoperitoneum is reduced and one can observe that there is no bleeding. A thoracic drain is positioned at the level of the 5mm port placed transthoracically. The diaphragmatic port opening site is closed.

Laparoscopic right hepatectomy on cirrhotic liver after transarterial chemoembolization (TACE) and portal vein embolization (PVE) for hepatocellular carcinoma (HCC)
We reported the case of a 70-year-old man in whom an F4 cirrhosis and a well-differentiated hepatocellular carcinoma were evidenced and managed by a laparoscopic right hepatectomy after transarterial chemoembolization and portal vein embolization. The operation starts with the control of the hepatic pedicle. A Doppler ultrasound is performed. It will reveal the relation of the lesion with the vein. The different right hepatic structures are identified, clipped and divided. Mobilization of the right liver is then initiated. The gallbladder, which is kept in place, is used for traction purposes. Parenchymal transection is begun with the assistance of Ultracision®, Aquamantys®, and Dissectron®. The portal structure and the hepatic vein are identified. The parenchymotomy is carried on and the identification of the right hepatic vein is going to be achieved. The origin of the right hepatic vein is dissected at its upper part and its lower part, in order to encircle it with a tape and divide it with a stapler. Once completed, the medial part of the right triangular ligament is further divided. Mobilization is continued on the same part from both sides, changing traction. The right liver is placed in a bag and removed. The cavity is cleansed. The hemostasis and biliostasis are controlled on the transection.

Laparoscopic right hemihepatectomy with augmented reality
We report the case of a 42-year-old woman who underwent a laparoscopic right hemihepatectomy for a hepatic metastasis. The intervention is begun with the exploration of the entire peritoneal cavity and an intraoperative ultrasound exam of the liver. The lesion is identified by means of augmented reality. Dissection of the different vascular structures is then performed at the level of the hepatic pedicle. A clamping test of the right branches is achieved. The right branch of the hepatic artery and the right portal vein are clamped, hence creating the demarcation area, which is identified by means of the coagulating hook. Declamping of portal and arterial structures coursing towards the right liver is achieved. The right branch of the portal vein is divided between two clips. The right branch of the hepatic vein is also divided between two clips. After mobilization of the right liver, the hepatotomy is begun. The first superficial centimeters are divided using an ultrasonic dissector (Ultracision®). Dissection is then carried on by means of a Cusa® Dissectron® Ultrasonic Surgical Aspirator. The largest structures are subsequently dissected intraparenchymally, and then clipped and divided. Hemostasis is completed using a radiofrequency instrument. The right biliary tract is dissected intraparenchymally, clipped and divided. The right hepatic vein is divided by means of a stapler. The specimen is placed in a bag, which is extracted by means of a small Pfannenstiel incision. Hemostasis is controlled as the pneumoperitoneum is reduced. A blade is positioned in the hepatectomy area.

Laparoscopic left pancreatectomy with spleen preservation for multiple neuroendocrine tumors
Insulinoma is the most common functional neuroendocrine tumor of the pancreas. Most insulinomas are benign and solitary. Surgical resection is preferred for insulinomas and cure is achieved in more than 90% of the patients. Successful surgery requires accurate localization based on contrast enhanced CT-scan, PET-scan, and intraoperative ultrasound. This video shows a laparoscopic left pancreatectomy in a young patient presenting with typical symptoms evocative of Whipple's triad. Preoperative imaging studies identified two pancreatic tumors. Laparoscopic exploration and ultrasound identified four distinct tumors, all of them expressing somatostatin and insulin. This clinical case highlights the necessity and value of ultrasound exploration during surgery for neuroendocrine tumors.

Typical laparoscopic four-trocar transabdominal adrenalectomy for a 5cm right-sided pheochromocytoma
This is the case of a female patient presenting with a typical 5cm right-sided pheochromocytoma was operated on laparoscopically. Preoperative 3D MRI reconstruction allowed to precisely identify surgical landmarks. The procedure was carried out typically. Four ports were used, and dissection aimed to first mobilize the liver. Control of the main adrenal vein was achieved as the first operative step. Medial, superior, and inferior arteries were dissected and controlled successively. Total freeing of the gland was performed with no manipulation or effraction of the gland's capsule. The postoperative course was uneventful. Small-sized pheochromocytomas are excellent indications for a laparoscopic approach with early control of the vein.

Video-assisted parathyroidectomy using augmented reality
The effectiveness of preoperative imaging to detect parathyroid adenomas allows for a targeted minimally invasive video-assisted approach. In our department, at the IRCAD, special software is used to virtually reconstruct the neck and its structures from mere CT-scan images of the cervicomediastinal region. This virtual reconstruction helps to precisely define the location of the parathyroid adenoma in relation to the superior part of the sternum, to the inferior thyroid artery and to the thyroid gland, hence guiding the surgeon in the proper identification of anatomical landmarks.
The reconstruction also helps to control the absence of "non-recurrent" recurrent nerves showing the presence of a right brachiocephalic arterial trunk.

Robot-assisted left adrenalectomy for Conn's adenoma
As laparoscopy is the standard approach to perform an adrenalectomy, robotic assistance is considered as an effective tool to perform this resection. Surgical steps follow those established for laparoscopy (i.e., mobilization of the spleen and of the pancreas in a patient placed in a lateral position, identification of the renal vein, control and division of the adrenal vein, successive freeing of the medial, external, inferior, and finally posterior aspects of the gland. The sealing devices such as ultrasonic dissectors are well adapted to perform this resection, and to safely control adrenal arteries. Robotic assistance takes full benefit from the degrees of freedom of the tips of the instruments and allows for an easy adrenal gland mobilization and removal.

Primary hyperparathyroidism cure using 3D CT-scan reconstruction
Parathyroid surgery has largely benefited from advances in preoperative imaging modalities allowing to determine potential adenomas. Conventionally, ultrasonography and scintigraphy with 99mTc-sestamibi (MIBI) provide sufficient information to guide the surgical procedure. Specific software has been developed at the IRCAD to allow for the 3D reconstruction of the entire cervical structures. The handling of such reconstruction helps to perform a precise preoperative assessment. Arterial reconstruction allows to predict the existence of an arteria lusoria and of a non-recurrent recurrent nerve. In this case, the position of a potential adenoma in relation to the inferior thyroid artery allows to anticipate that it is not an adenoma but a thyroid nodule. A second potential target is visualized inferiorly. These two potential locations will be explored during the video-assisted surgical intervention.

Posterior approach to laparoscopic left adrenalectomy including virtual reality simulation
Since M. Gagner published the first case of a transperitoneal laparoscopic adrenalectomy in 1992, the laparoscopic adrenalectomy has gradually become the standard operation for removing adrenal tumors. Compared to a traditional adrenalectomy, a laparoscopic adrenalectomy has a number of advantages, including less blood loss, a shorter hospital stay, a quicker recovery, and fewer complications. There are many ways to approach the adrenal gland laparoscopically, such as by a lateral transperitoneal approach, anterior transperitoneal approach, lateral retroperitoneal approach, and posterior retroperitoneal approach. This video shows a posterior left adrenalectomy using virtual reality simulation.

Laparoscopic pericystectomy for an 8cm hepatic hydatid cyst with 3D reconstruction
This is the case of a female patient presenting with epigastric pain. An 8cm liver cyst is identified on the examination. Given her previous medical and clinical history, the patient has a hydatid cyst. Serologic tests remain negative. This hydatid cyst is no longer active. Surgery is indicated given the symptomatology and the patient’s strong desire for the intervention. Indications for the surgical resection of non-active hydatid cysts remain rare. They mainly concern big cysts that may generate typical clinical signs of pain, heaviness and epigastric impairment. A standard pericystectomy performed in a stepwise manner should allow to resect this cyst without any resection of the liver parenchyma.

Laparoscopic distal pancreatectomy with spleen and vessel preservation
This is the case of a female patient presenting with a 12mm endocrine tumor located at the pancreatic isthmus. To manage this case, a distal pancreatectomy is decided upon. This tumor measures 16mm in its transverse diameter and it is located just above the portal vein. The CT-scan and its 3D reconstruction helps us to plan the surgical intervention. The whole pancreas along with the splenic vessels (splenic vein and artery) are reconstructed. The objective is to precisely locate the tumor in order to determine the resection modalities. A distal pancreatectomy with preservation of the splenic vessels is therefore decided upon.

Laparoscopic left pancreatectomy with spleen preservation for a suspicion of IPMN
Laparoscopic distal pancreatectomy is suitable for benign and premalignant neoplasms located in the body and tail of the pancreas. Spleen preservation following distal pancreatectomy is known to be safe. There are two distinct approaches to preserve the spleen during the dissection of the distal pancreas. The classic design is to identify, isolate, and preserve the splenic artery and vein. Alternatively, the splenic artery and vein are ligated with the pancreas, and perfusion of the spleen is assured by the short gastric vessels. Both are accepted as appropriate techniques to address a mass in the tail of the pancreas. This video demonstrates a left pancreatic resection with spleen preservation and ligation of the splenic artery and vein.

Alternatively, the splenic artery and vein are ligated with the pancreas, and perfusion of the spleen is assured by the short gastric vessels. Both are accepted as appropriate techniques to address a mass in the tail of the pancreas. This video demonstrates a left pancreatic resection with spleen preservation and ligation of the splenic artery and vein.
Laparoscopic resection of liver segments V and VIII for colorectal metastasis
Laparoscopic liver resection in selected patients in highly specialized centers provides comparable oncological results to treatment with open liver resection for patients with colorectal liver metastases. In this video, we present the case of a patient who underwent the resection of two liver segments in the context of a colorectal pathology. Initially, this lesion was estimated as sitting in the liver’s segment IV, but using a specific software dedicated to reconstructions of CT-scan data, it was discovered that this lesion was situated across segment V and segment VIII. This reconstruction allows to obtain a perfect visualization of the different relationships between the vessels and also allows to guide the procedure and to simulate the operative maneuver.

Segment III hepatocellular carcinoma (HCC) and major liver cirrhosis: laparoscopic resection
Laparoscopy for liver resection is a highly specialized surgical field because liver surgery presents severe technical difficulties, such as control of bleeding and risk of gas embolism. This video presents the case of a 60-year-old patient presenting with significant liver cirrhosis. During follow-up, a 3cm HCC located in the left liver was diagnosed. CT-scan was reconstructed in order to precisely define the landmarks regarding position of the tumor to the vessels. A laparoscopic approach was decided upon. As expected, a major liver cirrhosis is diagnosed. A parenchyma preserving hepatectomy is performed.

Laparoscopic left adrenalectomy for Conn's adenoma: three trocar technique
Conn's disease is a condition in which the adrenal glands produce too much aldosterone. Prevalence estimates for Conn's syndrome is about 0.03-1.2% of the population with hypertension.
Many patients with Conn's disease have a high blood pressure that is difficult to control. This increases the risk of stroke, heart disease and kidney failure. When Conn's disease is caused by a tumor (benign adrenal adenoma), surgical resection is advised. This video demonstrates the case of a woman presenting with Conn’s disease. The preoperative work-up demonstrated a tumor located on the left adrenal gland. The patient presented an elevated aldosteronemia and the CT-scan demonstrated a 2cm left adrenal tumor. The patient is placed in a full lateral position, on the right side.

Laparoscopic splenopancreatectomy assisted by augmented reality for pancreatic cancer
Soper et al. in 1994 were able to establish the safety and efficacy of laparoscopic distal pancreatectomy in an animal model, with no evidence of pancreatic leaks or fistulas. Later, in 1996, Cuschieri et al. described the technique they used to perform laparoscopic distal 70–80% pancreatectomy with en-bloc splenectomy in a group of five patients with intractable pain due to chronic pancreatitis. The authors demonstrated that this operation can be performed laparoscopically within an acceptable operating time and without major complications with advantages that include smaller incisions, less pain, and shorter postoperative recovery.
Identification of anatomical landmarks is crucial for this kind of procedure expecially when treating cancer. Augmented reality is a new tool to improve oncological safety, confirming the ideal dissection plane and anatomical landmarks, and to maximize functional preservation. The objective of this video is to demonstrate how to perform a splenopancreatectomy with removal of pancreatic cancer while keeping sufficient safety margins. Augmented reality is used in order to clearly identify the position of the anatomical landmarks: the splenic vein and artery, as well as the exact position of the tumor so that a sufficient resection margin can be identified.

Minimally invasive video-assisted parathyroidectomy for primary hyperparathyroidism
In recent years, the advances in preoperative localization studies, the availability of intraoperative parathyroid hormone (PTH) assay and the introduction of cervicoscopy revolutionized the surgical treatment of primary hyperparathyroidism (PHPT).
Minimally invasive video-assisted parathyroidectomy (MIVAP) is an efficacious and feasible procedure with the same complication rate as conventional surgery and has significant advantages in terms of cosmetic results, postoperative pain, recovery, and patient satisfaction. MIVAP should be considered a valid and validated option for the treatment of sporadic primary hyperparathyroidism, especially in case of a suspected single adenoma. This video demonstrates a minimally invasive approach for the excision of a right superior parathyroid adenoma in an inter-crico-thyroid position in a 65-year-old female patient.

Laparoscopic left adrenalectomy for Conn's disease: virtual reality and exposure for vascular approach
This is a very detailed and didactic video demonstrating laparoscopic left adrenalectomy. All the critical steps are presented clearly and the surgical approach is explained at each stage. All the dissection is performed with only a hook cautery and atraumatic graspers. This is an excellent video for laparoscopic surgeons interested in learning adrenalectomy.

Key landmarks in this step are the splenic, adrenal, and renal veins—and the three main arterial pedicles of the latter that supply the left adrenal gland. The steady mobilization of the pancreas with retraction to the left with the spleen allows the authors to identify the renal vein, clear identification of which is essential. Steady dissection of the superior border of the renal vein enables positive identification of the adrenal vein. The authors dissect it circumferentially from the superior border of the renal vein up to the origin of the phrenic vein.

Laparoscopic spleno-pancreatectomy for cancer
Laparoscopic spleno-pancreatic resection performed for adenocarcinoma in the tail of the pancreas. This case demonstrates how a complex resection can be undertaken laparoscopically using a stepwise approach. Difficulty was encountered with division of the pancreas and the management of this problem is discussed.

The surgeon stands between the patient's legs with the table in the reverse Trendelenburg position. The authors place three 10-mm ports across the upper abdomen with additional 5-mm ports in the left subcostal epigastric area. The camera is placed in the supraumbilical port. The laparascopic approach provides superior visualization, and tactile assessment of the pancreas. Mobility of the tumor is important to determine feasibility of resection. Laparoscopic ultrasound can delineate the tumor and surrounding structures.

Virtual reality applied to video-assisted left superior parathyroidectomy
This video demonstrates how virtual reality is applied to video-assisted left superior parathyroidectomy. The virtual reconstruction is done from a preoperative contrast CT scan. The anatomy is then recreated layer by layer starting from the skin to the bone. Every anatomical structure can be removed or added back, in order to visualize areas that are normally not easily accessible and therefore difficult to identify. The relation with the adjacent vascular structures, arteries and veins, can also be very precisely established. A two cm horizontal neck incision is made below the sternal notch. The surgeons demonstrates a careful dissection of the anterior and lateral aspect of the thyroid. This manoeuvre allows to easily reach the area that had been previously virtually reconstructed. Once the gland is freed from its attachment the vascular pedicle is identified, isolated and clipped.
