A Multicenter Prospective Randomized Controlled Study of RPD Versus LPD

In this trial, subjects proposed for PD were randomly divided into two groups, LPD and RPD, according to inclusion and exclusion criteria. Patients in both groups were operated and received perioperative management under the same surgical team and were operated according to the standard PD surgical approach. Subsequently, perioperative clinical data and long-term prognostic data of subjects in both groups will be collected and statistically analyzed to explore a better surgical approach.
