Overview

The purpose of this study is to determine whether robotic surgery has limitations in terms of patient age, tumor size, location, and vascular relationship when compared to open surgery for pancreatic cancer. Whether robotic surgery has advantages over intraoperative bleeding, operative time, postoperative complications (bleeding, infection, pancreatic fistula) and postoperative hospital stays compared to open surgery.And the differences in lymph nodes harvest and postoperative survival between two groups.
