This retrospective study reports the experience of handling SPN in a tertiary center of Eastern India over a 14-year period. Most of the 28 patients were female, and the common symptoms were abdominal pain and palpable abdominal mass. Despite the large size of the tumors, complete surgical resection was possible. The postoperative complications were relatively high, but no patients developed recurrence during the follow-up period.
Background: Solid pseudopapillary neoplasms (SPN) of the pancreas are rare tumors accounting for 0.9-2.7% of all exocrine pancreatic tumors. Very few studies comprising of more than 10 patients have been published. The aim of the present study is to report on our experience with SPNs over a period of 14 years from a tertiary center of Eastern India. Methodology: Data of all patients whose histopathology reports of surgically resected specimen confirmed SPN were retrospectively reviewed in the present study. Results: Twenty-eight patients had a pathologically confirmed diagnosis of SPN. Twenty-five (89.3%) patients were females with a median age of 26 (15-45) years. Abdominal pain (89.2%) was the most common presenting symptom. Abdominal mass was palpable in 12 (42.8%) patients. The mean size of the tumor was 9.03 cm (range, 4-25 cm). The most common location of the tumor was in the body and tail of pancreas (35.7%). The most commonly performed operation was distal pancreaticosplenectomy (n = 17, 60.7%), followed by Whipple's procedure (n = 8, 28.5%). Thirty postoperative complications developed in 23 (82.1%) patients. The operative mortality was 3.5% (n = 1). The median hospital stay was 10 (5-25) days. Over a median follow-up period of 36 months (range), no patient developed recurrence. Conclusion: Although the size of tumor was quite large at the time of initial presentation, complete surgical resection was possible in all the patients. In experienced hand, surgery can be performed with acceptable perioperative mortality and excellent long-term outcomes.
