Insulinoma Misdiagnosed as Dumping Syndrome after Bariatric Surgery

Abstract: Hypoglycemic episodes after obesity surgery are not always related to dumping syndrome. The persistence of hypoglycemia in spite of nutritional counseling should raise the possibility that there may exist other causes. Insulinoma, the most common cause of endogenous hyperinsulinemia, should be investigated in these patients, since it is a tumor that can be cured.

“…Intriguingly, pancreatic histology from some patients with neuroglycopenia suggests the possibility of islet expansion (so-called 'nesidioblastosis') [7,8]. Likewise, insulinomas have also been identified in post-bypass patients [14,15]. By contrast, other studies have not found increased beta cell mass in patients with post-bypass hypoglycaemia compared with BMI-matched autopsy controls, but rather increased nuclear diameter, which is potentially consistent with hyperfunctional islets [16].…”

“…Além disso, 70% destes pacientes referiram mudanças alimentares no intuito de prevenir os sintomas, de certa forma privando-se da ingestão de alimentos calóricos, cabendo observar que embora os mecanismos fisiopatológicos relacionados à síndrome de dumping ainda permaneçam obscuros, sua associação com a ingestão de alimentos calóricos já é descrita na literatura desde o início do século passado, e mantém-se presente na avaliação do dumping em pacientes submetidos a procedimentos bariátricos 21 . Zagury, descreve a síndrome de dumping como um efeito colateral benéfico, uma vez que auxiliaria na perda de peso dos pacientes operados, que tendem a limitar a quantidade de comida ingerida -em muitos casos, os pacientes se disciplinariam para evitar a síndrome através de mudanças na quantidade e qualidade dos alimentos 22 . Schauer 21 e Marema 23 propõem até que o reganho de peso observado em alguns pacientes cerca de dois a três anos após a operação de bypass gástrico estaria associado à amenização dos sintomas de dumping, entre outros fatores.…”
