Intraoperative Ultrasound Guided Laparoscopic Spleen-Preserving Distal Pancreatectomy for Primitive Neuroendocrine Tumors in a Pediatric Patient With MEN-1.

This case details the presentation and surgical management of a 15-year-old male patient with multiple endocrine neoplasia syndrome type 1 (MEN1) who required distal pancreatectomy for multiple nonfunctional pancreatic tumors. An intraoperative ultrasound was utilized to allow for proper location of the distal pancreatectomy, as well as visualization of the splenic vessel relationships and to ensure all lesions were contained within the specimen. Pathology demonstrated 5 well-differentiated neuroendocrine tumors with no evidence of malignancy. This case utilized innovative technology and a multidisciplinary approach in a challenging case to achieve a safe minimally invasive resection. The use of ultrasound intraoperatively provided confidence that all lesions had been identified, as well as demonstration of safe planes separate from the nearby vasculature.
