CEPERO VALDES, Manuel et al. Usefulness of intraoperative echography for resection of a insulinoma located in the head of pancreas. Rev Cubana Cir [online]. 2011, vol.50, n.2, pp. 157-203. ISSN 1561-2945.

The insulinoma is the more frequent neoplasms among the neuroendocrine tumors of pancreas. The aim of present paper is to describe the clinical picture, laboratory and imaging examinations and the surgical features as well as the complications in a patient diagnosed with insulinoma without evidences by preoperative images. Surgery was prescribed on the base of clinical and analytic evidences of hypoglycemia and hyperinsulinism and the carrying out of an exploratory laparatomy without any lesion with direct palpation of pancreas. Intraoperative echography was used to locate a 0,8cm nodule in the head of pancreas. After enucleation the only postoperative complication was a low-flow pancreatic fistula with a spontaneous remission. The histological diagnosis was a benign insulinoma. Patient had a clinical reversion of symptoms in addition to normalization of glycemia values, compared to those intraoperative.
