INTRODUCTION: Distal pancreatectomy with spleen preservation and splenic vessel excision is a commonly used technique. However, it produces significant gastrosplenic circulation and splenic function changes. PURPOSE: The aim of this work was to determine the immediate consequences on gastrosplenic circulation, late consequences on splenic function, and development of varicose veins. METHODS: Thirty-five patients with pancreatic tumors and anatomical feasibility were included. Preoperative splenic circulation was evaluated by dynamic contrast-enhanced computed tomography (CT) scans. Early splenic perfusion was assessed by CT 7 days after surgery and late changes in gastrosplenic circulation 6 months after surgery. Varicose veins were evaluated by CT and endoscopy 6 months after surgery. Pitted cells and Howell-Jolly bodies were used as markers of splenic function. Postoperatory findings included changes in splenic perfusion 7 days and 6 months after surgery, development of varicose veins on CT scans and endoscopy, and detection of markers of splenic hypofunction on blood smears. RESULTS AND CONCLUSION: Seven days after surgery, 63% of patients had some degree of splenic hypoperfusion, and 6 months after surgery, 83% of patients had normal perfusion. CT scans showed varices in 26 patients, and endoscopy revealed varicose veins in 11. Two patients experienced bleeding; markers of splenic hypofunction were found in 59% of cases.
