Tóm tắt

RACIONAL: O insulinoma é uma neoplasia que pertence ao grupo de tumores neuroendócrinos do pâncreas; embora raro, é o mais freqüente entre eles. OBJETIVO: Avaliar os resultados clínico e imunohistoquímico de doentes com insulinoma de pâncreas submetidos a tratamento cirúrgico. PACIENTES E MÉTODOS: Foram detalhados o quadro clínico, exames laboratoriais e de imagem, dando ênfase aos aspectos cirúrgicos, complicações e acompanhamento, a médio e longo prazos, de 12 doentes portadores de insulinoma. A cirurgia foi indicada para todos, com base nas evidências clínicas e laboratoriais de hipoglicemia e hiperinsulinemia. RESULTADOS: Em sete doentes conseguiu-se a localização prévia da lesão; em cinco, sua localização foi identificada durante a cirurgia mediante palpação e através do ultra-som intra-operatório. O procedimento mais freqüentemente utilizado foi a ressecção pancreática em oito doentes. A complicação cirúrgica mais freqüente foi a fístula pancreática, observada em sete doentes. Dois apresentaram tardiamente diabetes mellitus. Não houve mortes na presente casuística. CONCLUSÃO: Na totalidade dos doentes obteve-se a reversão clínica dos sintomas, caracterizada pelo desaparecimento da tríade de Whipple, além de normalização ou aumento dos níveis de glicemia, quando comparados aos valores do pré-operatório.
