The research contents of this study include: patients with insulinoma near the main pancreatic duct in the head and neck of the pancreas were randomly divided into two groups: the preoperative pancreatic duct stent enucleation group (stended EN), the direct en group (DEN), the Sen group asked a digestive endoscopist to place the pancreatic duct stent before surgery, and the next day or the next day after surgery, and the den group received enucleation directly. The safety of the two groups was compared, including the evaluation of surgical effect Postoperative complications and long-term prognosis based on follow-up data analysis; At the same time, the differences between the two groups were evaluated from the perspective of health economics.
The purpose of this study is to compare the clinical efficacy and economic cost of enucleation after placement of pancreatic duct stents before surgery with that of direct enucleation alone, and to evaluate its safety and feasibility.
