ABSTRACT

Background:

Solid pseudopapillary tumor of the pancreas is a rare low-grade malignant neoplasm. Most patients present with nonspecific symptoms until the tumor becomes large. Complete surgical resection by pancreatoduodenectomy is the treatment of choice for tumors located in the head of the pancreas

Aim:

To analyzed the clinicopathologic features, management, and outcomes of patients who had solid pseudopapillary tumor of the head pancreas and underwent surgical resection.

Methods:

Were analyzed 16 patients who underwent pancreatoduodenectomy for this condition.

Results:

Mean age was 25.7 years old, and 15 patients were female (93.7%). Nonspecific abdominal pain was present in 14 (87.5%). All underwent computed tomography and/or magnetic resonance imaging as part of diagnostic workup. The median diameter of the tumor was 6.28 cm, and surgical resection was performed with open or laparoscopic pancreatoduodenectomy without neoadjuvant chemotherapy. Postoperative complications occurred in six patients (37.5%) and included pancreatic fistula without mortality. The mean of hospital stay was 10.3 days. Median follow-up was 3.6 years, and no patient had local recurrence or metastatic disease.

Conclusion:

For these patients surgical resection with pancreatoduodenectomy is the treatment of choice showing low morbidity, no mortality, and good long-term survival.
