Introduction: There are few reports of surgery which preserve the function of pancreas for benign or low malignant tumors. While we have introduced laparoscopic pancreaticoduodenectomy (LPD), we have also performed laparoscopic pancreas-sparing duodenectomy (LPSD). In the present study, we investigated surgical techniques and results of LPSD.
Materials and methods: Between October 2019 and January 2022, 3 patients were underwent LPSD. The procedure was performed after obtaining approval from the Ethics Review Committee of our hospital.
Results: Three patients conducted LPSD were all males with a median age of 74 years, and diagnoses were adenomas of duodenum in 2 cases and gastrointestinal stromal tumor of duodenum in 1 case. The median blood loss was small amount. The median operative time was 430 minutes, and the median postoperative hospital stay was 13 days. One of the cases was performed with conversion to HALS. In LPSD, an intraoperative ultrasonography and an intraoperative radiographic contrast study were performed to confirm that the ampulla of Vater was preserved. There were no postoperative complications.
Conclusion: We experienced cases performed LPSD in our hospital. We need further research for feasibility and safety of the procedure.
