A Multicenter Prospective Randomized Controlled Study of RPD Versus LPD

laparoscopic pancreaticoduodenectomy(LPD) and Robot Pancreaticoduodenectomy (RPD), as two minimally invasive methods of pancreaticoduodenectomy(PD), have obvious advantages over traditional open pancreaticoduodenectomy(OPD) in terms of reducing surgical trauma and hospitalization time, but there are few studies on their perioperative safety and prognostic effects.However, there are few studies on the perioperative safety and prognostic effects of both procedures. In this trial, the perioperative data and prognosis of both procedures were collected and analyzed through a prospective, multicenter approach to investigate the advantages and disadvantages of both procedures.
