Abstract
Background/Aim: In the present study, we investigated the acute and late phases of splenic circulation after spleen-preserving distal pancreatectomy (SPDP) involving the division of splenic vessels. Methods: An acute phase of splenic circulation was evaluated by laser flow meter and the late phase was estimated by 99mTc-galactosyl human serum albumin spleen scintigraphy. Results: Splenic blood supply, evaluated by laser flow meter immediately after SPDP, dropped to one half of the prior blood supply. However, blood supply recovered 10 days after SPDP, as estimated by 99mTc-galactosyl human serum albumin spleen scintigraphy. Conclusion: There are two variations of SPDP: SPDP without preservation of the splenic artery and vein, and SPDP with preservation of the splenic artery and vein. The disadvantage of the former is the resulting decrease in splenic blood supply. The present findings may help to make up for this disadvantage.
