ABSTRACT
Insulinomas represent the most common cause of organic hypoglycemia. They are rare tumors: a review of the world literature reported a total number of 2000-3000 cases. The clinical diagnosis is based on the Whipple triad, which consists of: a) symptoms of hypoglycemia, b) blood glucose level: 40-50 mg/dl during the crisis, c) relief of symptoms after oral or intravenous administration of glucose. The most ticklish problem is the settlement of the accurate location of the tumor. Nowadays, there are many diagnostic methods; one of the best appears to be intra-operative ultrasonography. The authors analyse a series of 16 patients, operated between 1985 and 2002 in "I. Juvara" Surgical Clinic and present their opinions concerning tactic and technical aspects of different surgical procedures, with their advantages and limits. The results of the surgical treatment are detailed. There are also mentioned new imagery techniques and laparoscopic procedures, from recent medical issues.
