This clinical trial is about the survival benefit of extended lymphadenectomy and nerve clearance versus standard lymphadenectomy in pancreaticoduodenectomy of pancreatic adenocarcinoma，which is a multicenter，prospective，ramdomized clinical trials.
The purpose of this clinical trial is for assessing the survival benefit of extended lymphadenectomy and nerve clearance versus standard lymphadenectomy in pancreaticoduodenectomy of pancreatic adenocarcinoma. And we will focus on the R0 resection using LEEPP(Leeds Pathology Protocol) methods to check whether the tumor is eradicated or not.

The investigators will implement the pancreaticoduodenectomy using the principle of "Total Peripancreas Excision" to resect the lymph node and nerve plexus. The lymph node include standard 5,6,8a,12b1,12b2,12c,12a-b,14a-b,17a-b and extended 8p,9,12a,12p,14a-d,16a2,16b1 of the abdominal lymph node.
The investigators will implement the pancreaticoduodenectomy using the standard lymphadenectomy. The lymph node include 5,6,8a,12b1,12b2,12c,12a-b,14a-b,17a-b of the abdominal lymph node.
