Acidose metabólica por hiperglicemia transitória pós enucleação de insulinoma pancreático

Abstract: InTRODUÇÃOO insulinoma do pâncreas é a neoplasia endócrina funcionante que acomete com maior frequência esta glân-dula, e origina-se a partir das células beta das ilhotas de Langerhans. O quadro clínico é caracterizado, fundamentalmente, pela presença de sintomas neuroglicopênicos e neurovegetativos 8 . Classicamente, a tríade descrita por Whipple em 1938, se constitui na melhor forma de identificar e diagnosticar esta neoplasia 10 . O tratamento de escolha é o cirúrgico, que consiste na enucleação ou ressecçã… Show more

“…Episodes of acute hyperglycaemia, such as those described here, can generate intense metabolic acidosis and a hyperosmolar hyperglycaemic state. 38 In these cases, insulin deficiency and an increase in counterregulatory hormones cause excessive release of free fatty acids from adipose tissues, oxidised to ketone bodies in the liver, resulting in ketonemia and metabolic acidosis. 39 This study demonstrates the importance of rigorous glycaemic monitoring in patients with GIST presenting with paraneoplastic hypoglycaemia undergoing surgical resection.…”
