A Prospective Clinical Study Using an Artery-first Intermediate Approach in Robot-assisted Pancreaticoduodenectomy
February 23, 2023 updated by: The First Affiliated Hospital of University of South China
A Prospective Clinical Study of the Safety and Efficacy of Robot-assisted Pancreaticoduodenectomy Using an Artery-first Intermediate Approach
Pancreaticoduodenectomy, as a standard surgical procedure for malignant tumors of the head of the pancreas, ampulla and distal common bile duct, has brought the hope of clinical cure for these diseases.In the whole surgical process, the resection of the uncinate process of the pancreas is considered to be a major difficulty in the whole operation, which can affect the rehabilitation process and long-term prognosis.
Two main methods have been developed around the dissection of the uncinate process of the pancreas.
One is the Venous-first approach based on the portal vein-superior mesenteric vein axis.
The other is the Artery-first approach that first explores whether the superior mesenteric artery is invaded by the tumor to judge resectable.
The latter is gradually promoted in clinical practice because it can reduce intraoperative bleeding, reduce postoperative complications, and improve long-term prognosis.
The intermediate approach is a surgical approach based on the Artery-first approach and adapted to the layout of the robot arm.
The area between superior mesenteric artery and superior mesenteric vein was used as an intermediate area to treat the uncinate process of the pancreas in order to reduce perioperative complications and achieve better surgical results.
However, the safety and effectiveness of intermediate approach have not been verified,in this prospective clinical study, the investigators will use a robotic surgical platform to perform robot-assisted pancreaticoduodenectomy surgery through the intermediate approach to verify its safety and efficacy.

Detailed Description
Firstly, according to the inclusion and exclusion criteria, all patients from the First Affiliated Hospital of the University of South China who were to undergo robot-assisted pancreaticoduodenectomy were randomized into two groups, namely the standard approach group and the intermediate approach group.
The two groups were under the management of the same surgical team throughout the perioperative period, and were managed according to standardized Enhanced recovery after surgery approach.
The brief procedure includes: (1) Placement of the trocar in appropriate place; (2) An ultrasonic knife was used to cut the appetizing colonic ligament and expose the pancreas.
The superior mesenteric vein, common hepatic artery, proper hepatic artery and gastroduodenal artery were exposed, and the adjacent lymph nodes were dissected.
The right gastric artery and gastroduodenal artery were resected to expose the portal vein.
Dissect the common bile duct and peel the gallbladder from the bile fossa; The free common bile duct was dissected and suspended with a vascular sling.
(3) Resection of distal stomach and jejunum.
The pancreas was cut off with ultrasonic knife.
(4) Child reconstruction - pancreaticojejunostomy (pancreatic duct to jejunal mucosa anastomosis) , cholangiojejunostomy and gastrojejunostomy were adopted.
(5) Thoroughly rinse the abdominal cavity and place the abdominal drainage tube properly after checking for no active bleeding.The key point of surgery in the standard approach group was to first reveal portal vein-superior mesenteric vein and gradually complete the resection of the uncinate process of pancreas based on the reference of portal vein-superior mesenteric vein.
In the intermediate approach group, the area between superior mesenteric vein and superior mesenteric artery was defined as the intermediate area and dissection was performed in this area to achieve the removal of the uncinate process of pancreas.
Subsequently, data related to intraoperative conditions (such as operation time, amount of blood loss, etc.) and postoperative complications were collected and statistically analyzed to verify the safety of the intermediate approach, and short-term prognostic data was collected to verify its effectiveness.

Experimental: The intermediate approach
The key point of surgery in the standard approach group was to first reveal portal vein-superior mesenteric vein and gradually complete the resection of the uncinate process of pancreas based on the reference of portal vein-superior mesenteric vein.
|
The area between superior mesenteric vein and superior mesenteric artery was defined as the intermediate area and dissection was performed in this area to achieve the removal of the uncinate process of pancreas.
