Abstract

<p>A 58-year-old woman underwent laparoscopic distal gastrectomy for gastric cancer and laparoscopic-assisted partial resection of the small intestine for an arteriovenous malformation. Follow-up contrast-enhanced abdominal CT showed a peripherally enhanced mass lesion of 19 mm in diameter in the tail of the pancreas. Contrast-enhanced MRI also showed a mass lesion at the same site. There was no evidence of recurrence. The patient was diagnosed with a pancreatic neuroendocrine tumor, and laparoscopic spleen-preserving distal pancreatectomy was performed. She was subsequently discharged without postoperative complications. A histopathological examination revealed an epithelial cyst arising in the intrapancreatic accessory spleen, which is relatively rare and difficult to diagnose preoperatively. However, there is a need to pay attention to blood flow in the residual stomach while performing distal pancreatectomy in patients with a medical history of gastrectomy. Herein, we report a case of laparoscopic spleen-preserving distal pancreatectomy for an epithelial cyst arising in an intrapancreatic accessory spleen after distal gastrectomy.</p>
