Filter by:Aim of the study : To evaluate the effect and safety of "Heidelberg Triangle" dissection (TRIANGLE operation) combined with Pancreatoduodenectomy or Distal Pancreatectomy on the prognosis of pancreatic cancer and periampullary cancer . Methods : Patients who underwent pancreatoduodenectomy or Distal Pancreatectomy between 01 September 2016 and 30 December 2022 will be included in this retrospective analysis. 3D reconstruction is performed with preoperative enhanced CT, then the region of "Heidelberg Triangle" is categorized . The operation is completed by the same operation team. According to the operation mode, patients were divided into TRIANGLE group and non-TRIANGLE group and And followed up until recurrence, death or missed.
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.
the study is designed to compare the blood loss between laparoscopic vs open pancreaticoduodenectomy in a randomized clinical trial
Pancreaticoduodenectomy (PD) is one of the most complicated surgical procedure and one of the standard treatments for benign and malignant disease of pancreatic head and periampullary region. Improvements in surgical techniques and the perioperative management of patients undergoing PD have reduced the surgical mortality rates to less than 3% in high-volume medical centers. However, the incidence of postoperative complication remains high, which ranges from 30% to 50% and the pancreatic fistula rate ranges from 5% to 40%. The key point of PD is still the enteric reconstruction of pancreatic stump. There were different techniques of enteric reconstruction, including: invagination pancreaticojejunostomy, binding pancreaticojejunostomy, duct-to-mucosa pancreaticojejunostomy, Roux-en-Y pancreaticojejunostomy, and pancreaticogastrostomy and each technique had its advantages and disadvantages. We established a new digestive reconstruction technique named shark mouth modified pancreaticojejunostomy, which had theoretical advantages including easier performed; lower tension and less complication. The shark mouth modified pancreaticojejunostomy is an end-to-end pancreaticojejunostomy procedure which is between invagination pancreaticojejunostomy and binding pancreaticojejunostomy.The remnant of jejunum is shaped as shark mouth and then sutured with the pancreas remnant. After the surgery, the patients will be well followed up. The pancreaticojejunostomy time, post-operation complication, mortality and hospital stay will be documented to study the safety, efficiency and advantage of this new procedure.
Despite the fact that pancreatoduodenectomy is the standard treatment of malignant tumor at periampullary area, the morbidity and mortality rate with intra-abdominal collection, post pancreatectomy hemorrhage, and delayed gastric emptying, is still high at approximately 50-60%. The causes of these complications usually come from post-operative pancreatic fistula. Nowadays, several methods have been reported to reduce the incidence of pancreatic fistula after undergoing pancreatoduodenectomy, such as pancreatic stenting, the use of intravenous somatostatin, the use of sealant material and wrapping anastomosis by soft tissue. Wrapping pancreato-jejunal anastomosis with omentum is not a complicate procedure and requires no extra treatment expenses of the patient. It has been reported this technique has been applied in the non-randomized controlled trials and their data have significantly shown that the technique could reduce pancreatic fistula rate. Therefore, the researchers want to conduct an RCT study to compare complication rates between omental roll-up pancreato-jejunal anastomosis and non-omental roll-up groups.
