Overview

Surgery is the mainstay of treatment for insulinoma. It can be 80 to 100% curative in experienced surgical hands. The feasibility of surgery depends on the stage of insulinoma at diagnosis.

Surgery

Surgery is the mainstay of treatment for benign and resectable malignant insulinoma. It can be 80 to 100% curative in experienced surgical hands.[1][2]

Benign Tumors

Small well-encapsulated, solitary tumors:[1][2][3]

  • Tumors are localized with palpation in 70 % cases during surgery. Intra-operative ultrasound (IOUS) localizes in 86% of times. Palpation and IOUS together localize tumor in 83-98% cases.[4][5]
