Using the Root of the Mesentery to Guide a Novel Operative Approach for Laparoscopic Insulinoma Resection

Insulinoma is a functioning endocrine neoplasm appearing primarily in the tail and body of the pancreas, although it is also rarely found in the uncinate process. The sole treatment for insulinoma is surgical resection. However, for insulinoma in the uncinate process, traditional laparoscopic surgery is controversial owing to the fact that it is a complex operation and carries a high surgical risk. Herein, we report a novel approach to complete the exposure of uncinate process and tumor resections starting from the root of the mesentery.
