Abstract
The prevalence of insulinomas is 1–3 cases per million population per year of which 4–14% tumor is malignant. Weight gain is one of the symptoms of the disease, often resulting in morbid obesity with indications for surgical treatment. The presented clinical case demonstrates the successful treatment of malignant insulinoma with the manifestation of hypoglycemic syndrome after carrying out biliopancreatic bypass with longitudinal gastrectomy for morbid obesity.
