Comparison of Prognosis Between Open Pancreatic Surgery With Vein Resection and Reconstruction Versus Minimally Invasive Pancreatic Surgery With Vein Resection and Reconstruction for Pancreatic Cancer

The prognostic differences between open and minimally invasive radical pancreatic surgery combined with venous resection and reconstruction remain controversial, and there is a lack of high-quality evidence-based medical evidence to support either approach. Therefore, this study intends to conduct a retrospective cohort analysis, planning to enroll pancreatic cancer patients who have undergone radical pancreatic surgery (open vs. minimally invasive) combined with venous resection and reconstruction from multiple hospitals both domestically and internationally, and to collect relevant data. The primary objective is to evaluate the differences in postoperative thrombosis and the incidence of severe complications between the two groups. Furthermore, prognostic data will be collected to assess the impact of open versus minimally invasive pancreatic surgery combined with venous resection and reconstruction on both short-term and long-term all-cause mortality in pancreatic cancer patients.
