Robotic central pancreatectomy for a well-differentiated neuroendocrine tumor
In this video, we show a robotic central pancreatectomy for a well-differentiated neuroendocrine tumor. This is the case of a 50-year-old patient admitted to the emergency department for acute pancreatitis. CT-scan and MRI demonstrate the presence of a hypervascularized lesion of approximately 15mm in diameter, at the pancreatic isthmus. Scintigraphy does not evidence any intense uptake.
The colon and the omentum are detached and the stomach is suspended laparoscopically. The robot is docked using a lateral approach. A retropancreatic passage is achieved on the mesenteric-portal axis. An intraoperative ultrasonography is performed to visualize the tumor and delimitate the resection margins. After the dissection, the anastomosis is performed between the distal part of the pancreatic remnant and the posterior gastric wall.
A postoperative pancreatic fistula grade B was reported. It was successfully managed. The presence of a well-differentiated neuroendocrine tumor was confirmed. The patient was discharged on postoperative day 22.

Robotic distal pancreatectomy with splenectomy
This is the case of a 73-year-old asymptomatic female patient who presented with an incidental pancreatic lesion on CT-scan. Her previous medical history was relevant for systemic lupus erythematosus. On the CT-scan, a single hypervascular lesion in the arterial phase was identified in the distal pancreas. The lesion size was 3.1 by 3.3 by 4.3cm. Neither suspicious nodes nor distant metastases were found. The patient was considered to be ASA2 and ECOG0.
The patient was placed in a reverse Trendelenburg position. A 12mm port was placed in the umbilicus for the camera, and three 8mm ports were inserted to accommodate the robotic arms, and another 12mm auxiliary port was used.
The greater curvature of the stomach was released from the transverse colon to expose the supramesocolic area. The neck of the pancreas was dissected close to the splenic-mesenteric confluence. The inferior mesenteric vein opening to the splenic vein was identified, clipped and cut. The splenic artery was dissected, clipped and cut close to the celiac trunk. A stapler was placed in the neck of the pancreas and it was safely stapled. The splenic vein was dissected close to the confluence, and then clipped and cut. The distal pancreas and splenic ligaments were cut and . detached. The specimen was removed using a Pfannenstiel’s incision.
The duration of the procedure was 255 minutes. The estimated blood loss was 100mL. The patient was discharged on postoperative day 5 and no complication was observed over a period of 90 days. Pathology confirmed the presence of a neuroendocrine tumor (grade 2) as a 4cm single lesion and negative margins. One positive node was detected among 10 nodes harvested.

Laparoscopic enucleation of a pancreatic tumor: posterior approach
We report the case of a 55-year-old woman with a hypervascularized lesion at the posterior aspect of the pancreatic tail, which is evocative of an endocrine tumor of the pancreas. We decided to perform a laparoscopic enucleation of this tumor using a posterior approach. The patient is positioned in a right lateral decubitus. The intervention begins with the opening of the posterior mesogastrium, which allows to tilt the entire splenopancreatic block to the right. The tumor located on the posterior aspect clearly appears. An enucleation of the tumor is then performed using the monopolar cautery hook. In order to facilitate the lesion's exposure, a traction suture will be placed. This helps to expose the tumor. The inferior border of the tumor is freed from the splenic vein and the monopolar hook allows to perform a step-by-step enucleation. An intrapancreatic freeing of the lesion's deep plane is achieved using the Sonicision™ device. The tumor is placed into a bag and extracted through a port. The extemporaneous exam confirms the diagnosis of an endocrine tumor. Hemostasis is controlled. The splenopancreatic block is put back in its original anatomical position. There is no pancreatic fistula. The patient is discharged on postoperative day 5. The final diagnosis confirms a G1 endocrine tumor.

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.

Laparoscopic radical antegrade pancreatosplenectomy
Benign inflammatory lesions, cystic neoplasms, and neuro-endocrine tumours in the body and tail of the pancreas are considered good indications for laparoscopic distal pancreatectomy and/or en-bloc pancreatosplenectomy. Laparoscopic resection of malignant neoplasms has raised concern about the radicality of resection and oncological outcomes.
This video demonstrates the technique of laparoscopic radical antegrade pancreatosplenectomy (lap-RAP), which achieves a radical resection with clear circumferential margins. The resection proceeds from right to left to include a coeliac lymphadenectomy, early division of the splenic artery, splenic vein and neck of pancreas, and medial to lateral mobilization of the pancreas posterior to Gerota's fascia to ensure an adequate posterior oncological clearance.
Lap-RAP extends the benefits of laparoscopic pancreatectomy to include malignant lesions in the body and tail of the pancreas.
This video is recommended for experienced laparoscopic surgeons.
