Laparoscopic Duodenum-Preserving Pancreatic Head Resection: A Technique for the Treatment of Benign or Low-Grade Malignant Tumors (10 Cases Report).

Background: Laparoscopic duodenum-preserving pancreatic head resection (LDPPHR) is a surgical procedure that involves the removal of the pancreatic head while aiming to preserve the integrity of the digestive and biliary tracts. With advancements in laparoscopic techniques, the utilization of LDPPHR has been increasing. Methods: We retrospectively analyzed the clinical data of 10 patients who underwent laparoscopic duodenum-preserving total pancreatic head resection (LDPPHR-t) at our center from June 2019 to October 2021. Additionally, we analyzed the use of indocyanine green (ICG) in the initial stage of LDPPHR, based on current reports. Results: LDPPHR-t was successfully performed in all patients. After surgery, 3 patients experienced pancreatic fistula (Grade B), 2 patients experienced bile leakage, and 2 patients experienced postoperative hemorrhage. However, no patient exhibited recurrence or required secondary surgery. Conclusion: LDPPHR-t is a new method for treating benign and low-grade malignant tumors in the pancreatic head. However, it is associated with a high incidence of postoperative complications. In the initial stage, the use of ICG can assist surgeons in identifying the biliary duct and pancreaticoduodenal artery arcade.
