Insulinomas do pâncreas: diagnóstico e tratamento

BACKGROUND Despite its rarity, the insulinoma is the most common pancreatic neuroendocrine tumor. OBJECTIVE Analyze clinical and immunohistochemical data from surgical resection of the pancreas insulinoma. METHOD Twelve cases are described, concerning surgical aspects, complications and medium-long term outcome of patients. They underwent surgical treatment due to clinical suspicion and biochemical diagnosis of hypoglycemia and hyperinsulinism. RESULTS The insulinoma was identified preoperatively in seven patients, while intraoperative ultrasonography and palpation were necessary for diagnosis in the other cases. Eight patients underwent pancreatic resection and pancreatic leak was observed in seven cases. Two patients developed diabetes mellitus and no mortality occurred in the current series. CONCLUSION All patients presented satisfactory outcome and remained asymptomatic with normal glicemia levels.

Hemorragia digestiva por fístula de artéria subclávia direita anômala com o esôfago

Bleeding from an arterio-esophageal fistula is a rare and nearly lethal condition and surgical treatment is the only curative option. We report a case of bleeding from a fistula from an aberrant right subclavian artery to the esophagus. Diagnosis was made only at necropsy, despite of three previous laparotomies. This anatomical variation is found in 0.5% of the general population. Development of a communication between this artery and the esophagus, secondary to aneurysmatic dilatation or to prolonged nasogastric intubation, as probably occurred with this patient, is a extremely rare condition. Surgical treatment depends on the early recognition of clinical signs of the arterio-esophageal communication, before the onset of systemic complications of hypovolemic shock.Bleeding from an arterio-esophageal fistula is a rare and nearly lethal condition and surgical treatment is the only curative option.
