The Differences of Complications Between LPD(Laparoscopic Pancreaticoduodenectomy) and OPD(Open Pancreaticoduodenectomy)

Main objective: This project intends to design a simulated RCT project and clinically relevant RCT study to target, selecting the study titled "Short-Term outcomes Following Laparoscopic vs Open Pancreaticoduodenectomy in Patients With Pancreatic Ductal Adenocarcinoma: A Randomized Clinical Trial (Short-term Outcomes of Laparoscopic versus Open Pancreaticoduodenectomy in Patients with Pancreatic Ductal Adenocarcinoma)", use the cases in the Pancreatic Cancer Special Disease Cohort Database, compare the differences in complications and short-term prognosis between patients with pancreatic cancer after laparoscopic and open pancreaticoduodenectomy, investigate the efficacy and safety of laparoscopic pancreaticoduodenectomy, and provide the basis and reference of real-world data for clinical relevant studies. Secondary objective: To predict the incidence of postoperative complications and short-term outcomes of pancreatic cancer patients by comparing the difference of complications and short-term prognosis between laparoscopic and open pancreaticoduodenectomy, and to improve the treatment power of patients scheduled for surgery and postoperative patients.
