ObjectiveTo explore the safety and feasibility of the uncinate-process-first superior mesenteric artery (SMA) right posterior approach in laparoscopic pancreaticoduodenectomy (LPD). MethodsThe clinical data of 5 patients admitted to the Second Affiliated Hospital of Chongqing Medical University from December 2022 to May 2023 were retrospectively analyzed, all patients underwent uncinate-process-first SMA right posterior approach during LPD. ResultsAll 5 cases of LPD with uncinate-process-first SMA right posterior approach were successfully completed. The operative time was (366±51) min, the intraoperative blood loss was (140±42) mL, and the postoperative hospital stay was (11±2) days. All the postoperative pathological findings reached R0 resection. None of the 5 patients suffered from biliary leakage, bleeding, or gastrointestinal empties, and 2 patients suffered from biochemical fistula, the postoperative follow-up time was (7±2) months, and there was no recurrence during the follow-up period. ConclusionThe uncinate-process-first SMA right posterior approach is a safe and feasible surgical approach, especially for tumors with no obvious vascular invasion and diameter ≤2 cm.
