Abstract
Insulinomas represent <10% of pancreatic tumors. It is a functional neuroendocrine tumor that can cause recurrent and severe episodes of loss of consciousness due to hypoglycemia. Surgical removal is the only curative treatment. The selection of the optimal surgical technique must be individualized for each patient. Currently, there are emerging innovations in less invasive techniques that reduce morbidity. We present the case of a 23-year-old woman who underwent enucleation of an insulinoma localized at the tip of the pancreatic tail after laparoscopic surgery, with a focus on vascular and splenic preservation. The tumor was safely identified during surgery and enucleated without injury to the spleen and adjacent vascular structures or postoperative complications.
