To investigate the clinical efficacy and satety of robotic ultrasonic-coagulation-suture in spleen-preserving distal pancreatectomy with the Kimura the technique.

The study retrospectively analyzed 31 patients undergoing robotic pancreaticoduodenectomy and distal pancreatectomy from Oct, 2014 to Jan. 2020 in the affiliated of hospital of Qingdao University. The operation time, bleeding during placement, postoperative drainage volume, postoperative drainage fluid amylase, surgical expenses, drainage tube removal time, postoperative hospitalization days and the pathology were compared between the observation group and the control group.

There were 8 patients in the observation group, including 1 males and 7 females, age 23-62 years old, average age 43 years old; In the control group, there were 23 patients, including 5 males and 18 females, aged 19-75 years with an average age of 49 years. The single-factor analysis of the experimental group and control group showed: gender (P=0.584), age (P=0.445), postoperative complications (P=0.036), operation time (P=0.992), intraoperative bleeding (P=0.909), postoperative hospitalization(P=0.403), surgery expense(P=0.527).

Robotic ultrasonic-coagulation-suture is safe, reliable, simple. It is worthy of widespread promotion.
