To investigate the clinical effects of Warshaw and Kimura resection of splenic arterio-venous resection in the treatment of benign and borderline pancreatic tumors.

Clinical data of 60 patients treated from January 2015 to October 2018 who underwent laparoscopic caudectomy due to benign pancreatic body and tail tumors and some borderline tumors were retrospectively selected and divided into Kimura group according to different surgical methods（Kimura method caudectomy，n=34 cases）and Warshaw group（Warshaw coyotectomy，n=26 cases）. SPSS 23.0 software was used for data analysis. Postoperative complications were represented as［cases（%）］，and χ² test was used for comparison between groups. Measurement data such as perioperative indicators were represented by（

The amount of intraoperative blood loss in Kimura group was higher than that in Warshaw group（P<0.05），but there was no significant difference in operative time，postoperative anal ventilation time and hospital stay between the two groups（P>0.05）. The total complication rate in Kimura group was lower than that in Warshaw group（5.9% vs. 34.6%，P<0.05）. No tumor recurrence or gastric varicose bleeding occurred in both groups during postoperative follow-up.

Laparoscopic splenic-preserving pancreato-caudal resection is effective in the treatment of benign tumors and some borderline tumors. Compared with Warshaw method，Kimura method has more blood loss，but it is beneficial to spleen blood supply and functional protection，and has lower postoperative complications，which has certain advantages and is worthy of clinical application.
