Laparoscopic spleen‐preserving distal pancreatectomy: A novel technique with splenic artery resection and splenic vein preservation

Abstract

AbstractIntroductionLaparoscopic spleen‐preserving distal pancreatectomy (LSDP) is widely performed to treat benign and low‐grade malignant diseases. Although preservation of splenic vessels may be desirable considering the risk of postoperative complications, it is sometimes difficult due to tumor size, inflammation, and proximity of the tumor and splenic vessels. Herein, we present the first case of LSDP with splenic artery resection and splenic vein preservation.Materials and Surgical TechniqueA 40‐year‐old woman with a pancreatic tumor was referred to our hospital. Contrast‐enhanced computed tomography (CT) revealed a tumor in the pancreatic tail that was in contact with the splenic artery and distant from the splenic vein. The splenic artery and vein were separated from the pancreas near the dissection line. The splenic artery was resected after pancreatic dissection using a linear stapler. After the pancreatic tail was separated from the splenic hilum while preserving the splenic vein, the distal side of the splenic artery was resected, and the specimen was removed. The postoperative course was uneventful and the patient was discharged on postoperative Day 9. Four months after surgery, postoperative follow‐up CT findings showed neither splenic infarction nor gastric varices.DiscussionThis technique is an alternative method of splenic preservation when there is no attachment of the tumor to the splenic vein or uncontrolled expected bleeding of the splenic artery using the Kimura technique.
