Ref.	Spleen preserving %		Technical details
	LDP	ODP
Aly et al[23]	32.5	8.6	Both procedures, spleen vessel ligation were performed, leaving the short gastric vessels to supply the spleen (Warshaw)
Baker et al[24]	NA		In ODP, the benign and premalignant pathology, the spleen was routinely saved by means of the splenic vein and artery preserved
			In LDP, splenic salvage by means of Warshaw: ligating the splenic artery and vein but preserve the short gastric vessel
Butturini et al[25]	44.2	11.0	Both procedures, exposing the splenic vein up to the splenic hilum; the distal pancreas was detached from the splenic artery in the opposite direction by tractioning the parenchyma
Casadei et al[26]	NA		Mobilization of the distal pancreas from retroperitoneum and splenic vessels
DiNorcia et al[27]	15.5	15.6	For spleen preserving distal pancreatectomy, an attempt to spare the splenic artery and vein was made in all patients
Eom et al[28]	41.9	NA	For spleen preserving distal pancreatectomy, both the splenic artery and vein were preserved
Jayaraman et al[29]	18.9	14.0	When splenic preservation was performed, the splenic vein and artery were isolated
Kim et al[30]	40.9	5.70	In spleen preserving distal pancreatectomy, both the splenic artery and vein were preserved. In one case, the splenic artery was ligated with preservation of splenic vein. In the other case, both the splenic artery and vein were ligated, with preservation of short gastric vessels (Warshaw)
Vijan et al[31]	25	NA	If splenic preservation is indicated, the pancreas is dissected off the splenic vessels
