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

This study tests a surgical technique for removing small pancreatic tumors (enucleation) that uses a nerve block to temporarily reduce blood flow to the pancreas. This allows surgeons to remove the tumor more precisely while minimizing bleeding and preserving as much healthy pancreas tissue as possible. **You may be eligible if...** - You are an adult with a small pancreatic tumor suitable for enucleation (tumor removal without removing a large portion of the pancreas) - You are healthy enough to undergo abdominal surgery **You may NOT be eligible if...** - Your tumor is too large or positioned in a way that makes enucleation unsafe - You have conditions that make blocking the abdominal blood supply risky - You are pregnant - You have severe clotting or vascular disorders Talk to your doctor to see if this trial is right for you.
