Laparoscopic spleen-preserving distal pancreatectomy (LSPDP), a newly developed operative procedure, is indicated for benign and low-grade malignant disease of the pancreas. However, few studies have reported on postoperative splenic infarction after LSPDP. We report a case of complete splenic infarction and obliteration of the splenic artery and vein after LSPDP. The patient was a 69-year-old woman with a 35-mm cystic tumor of the pancreatic body who underwent LSPDP. Although the operation was completed with preservation of the splenic artery and vein, postoperative splenic infarction was revealed with left back pain and fluid collection around the stump of the pancreas on postoperative day 9. Fortunately, clinical symptoms disappeared within days and additional splenectomy was not needed. Splenic infarction was attributed to scattered micro-embolizations within the spleen after drawing strongly on the tape encircling the splenic vessels. Preserving splenic vessels in LSPDP is a demanding procedure. To prevent splenic infarction in LSPDP, we should carefully isolate the pancreatic parenchyma from the splenic vessels, and must avoid drawing tightly on the vessel loop encircling splenic vessels.
