[Surgical treatment of insulinoma. Experience at the Salvador Zubiran National Nutrition Institute].
Eighteen cases of insulinoma treated at the Instituto Nacional de la Nutricion in Mexico City are presented. The cases were operated on between 1959 and 1988, and include 10 women and 8 men with a mean age of 38. The duration of symptoms ranged between 4 and 96 months with a median of 27; 78% of the patients had neuropsychiatric symptoms, 61% seizures, and 55% loss of consciousness. One of the patients had evidence of type I multiple endocrine neoplasia. Diagnosis was established in all the patients with the demonstration of Whipple's triad and also with an elevated insulin determination in the last nine patients. In six cases the insulinoma was enucleated; in two a Whipple procedure was performed; in nine a distal pancreatectomy and in the remaining patient only resection of hepatic metastases; 67% of the tumors were diagnosed as benign solitary adenomas, 16.5% as carcinomas and the same number as hyperplasia. Operative mortality was 5.5%, and morbidity 44%. The three carcinomas survived 6, 8 and 36 months. Disappearance of the hypoglycemic symptoms was obtained in 93% of the cases of adenoma and hyperplasia.
