    Abstract:
    BACKGROUND: Solid pseudopapillary tumor (SPT) of the pancreas is a rare low-grade malignant tumor. Here, we aimed to determine the safety and feasibility of laparoscopic parenchyma-sparing pancreatectomy for SPT located in the pancreatic head. METHODS: From July 2014 to February 2022, 62 patients with SPT located in the pancreatic head were operated laparoscopically in two institutions. These patients were divided into two groups according to the operative strategy: laparoscopic parenchyma-sparing pancreatectomy (27 patients, group 1) and laparoscopic pancreaticoduodenectomy (35 patients, group 2). The clinical data were retrospectively collected and analyzed in terms of demographic characteristics, perioperative variables, and long-term follow-up outcomes. RESULTS: The demographic characteristics of the patients in the two groups were comparable. Compared to the patients in group 2, those in group 1 required less operative time (263.4 ± 37.2 min vs. 332.7 ± 55.6 min, p < 0.001) and experienced less blood loss (105.1 ± 36.5mL vs. 188.3 ± 150.7 mL, p < 0.001). None of the patients in group 1 had tumor recurrence or metastasis. However, 1 (2.5%) patient in group 2 showed liver metastasis. CONCLUSION: Laparoscopic parenchyma-sparing pancreatectomy is a safe and feasible approach for SPT located in the pancreatic head, with favorable long-term functional and oncological results.
