Splenic vessel preservation versus Warshaw's technique during spleen-preserving distal pancreatectomy: a meta-analysis and systematic review

Splenic preservation can be achieved through splenic vessel resection by Warshaw’s technique (WT) or by preserving the splenic vessels. This meta-analysis aims to provide evidence-based comparison regarding the perioperative outcome and long-term benefits between patients with and without splenic vessel preservation (SVP) during spleen-preserving distal pancreatectomy. A meta-analysis was performed to evaluate studies comparing splenic vessel preservation versus resection groups. Ten retrospective studies including 699 patients were eligible for an analysis of general, perioperative, and long-term outcomes. A further analysis composed of five subgroups was also conducted in terms of laparoscopic approach. Warshaw’s technique related to significant shorter operation time (P
