Study Overview

Enucleation of Pancreatic Tumor by Blocking Abdominal Trunk and Superior Mesenteric Artery

Pancreatic enucleation could preserve more healthy pancreatic tissues and functions with a low recurrence risk. However, conventional enucleation can cause significant intraoperative bleeding, especially in which tumors in the pancreatic head, neck, and uncinate process of pancreas, as these tissues are rich in blood supply, mainly including the abdominal trunk and the superior mesenteric artery. In this study, we developed a novel method to control the pancreatic blood flow in laparoscopic enucleation--blocking the abdominal trunk and superior mesenteric artery with vascular occlusion clips in the process of resection, and evaluated its effectiveness and safety.

Between March 2023 and May 2026, patients who underwent laparoscopic pancreatic enucleation by blocking both the abdominal trunk and superior mesenteric artery in the Second Affiliated Hospital of Zhejiang University would be included in our prospective study. Inclusion criteria: 1) benign or borderline tumors diagnosed pathologically, such as pancreatic neuroendocrine tumors, solid pseudopapillary tumors, and cystadenomas, without vascular invasion or distant metastasis;.2) tumors sited in the pancreatic head, neck, and uncinate process of pancreas; 3) blockade of both the abdominal trunk and superior mesenteric artery in the laparoscopic enucleation. Exclusion criteria:1) highly malignant pancreatic tumors, or tumors with infiltration or metastasis; 2) tumors of the body and tail of the pancreas;3) transfer to LPD or laparotomy. Patient characteristic including clinical, biochemical and radiological data will be recorded and analyzed. All patients will provide written informed consent before inclusion.
