Surgical Management of Solid Pseudopapillary Neoplasm of the Pancreas-an Experience from Tertiary Care Centre

Solid pseudopapillary neoplasm (SPN) is uncommon and constitutes to 1-2% of pancreatic tumours. Owing to its rarity, literature is sparse on its clinicopathological characteristics and surgical outcomes. Our study is a retrospective analysis of prospectively maintained data of patients with histologically proven SPN between January 2012 and December 2019. Patients' demography, clinical presentation, preoperative imaging, operative details, perioperative outcomes, and long-term follow-up were recorded and analyzed. A total of 14 patients were included in the study, all were females with a median age of 19.5 years (range 15-35 years). All presented with pain abdomen. Eight (57.1%) out of 14 patients were correctly diagnosed with contrast-enhanced computed tomography (CECT) abdomen. CECT revealed solid cystic well-encapsulated lesions in 12(85.7%) and homogenous mass lesions without cystic changes in 2 (14.2%) patients. The most common tumour location was head/uncinate process (57.1%). Eight (57.1%) underwent pancreaticoduodenectomy and 6 (42.8%) had undergone distal pancreatectomy. The median size of tumour was 10 cm (4.5-14 cm). The median postoperative stay was 9 days (range 4-20 days). Seven patients (50%) developed postoperative pancreatic fistula (Grade-A-6/7, Grade-B-1/7) and delayed gastric emptying (DGE) was noted in two (14.2%). R0 resection could be achieved in 13 patients (92.8%). Median follow-up period was 49.5 months. One patient had postoperative recurrence after 48 months of surgery. SPN is a rare tumour of pancreas. Surgical resection is associated with acceptable morbidity and is required for potential cure.
