RESUMO

O objetivo deste estudo foi determinar o padrão eletromiográfico do reflexo gastrocólico no cólon esquerdo (sigmóide), através da avaliação da atividade elétrica de controle (AEC), atividade elétrica de resposta (AER) e complexo motor migrante (CMM). Foram avaliadas 15 pacientes, do sexo feminino, submetidas à histerectomia, sem alteração clínica do trato gastrointestinal. A idade média foi de 40,2 anos. As pacientes foram controles de si próprias, tendo sido comparado o período pré com o per e pósprandial. Eletrodos bipolares cobertos por Téflon foram implantados a nível da tênia anterior do cólon esquerdo. Após a recuperação do íleo paralítico, realizou-se a coleta dos dados. Foi utilizado um sistema de aquisição de dados (DATA Q Série 200), que captou frequência entre 0,02 a 10 Hz e um software de análise de dados, (WINDAQ 200) que funcionou no ambiente Windows. Os resultados obtidos evidenciaram que a AEC e AER de curta duração (n/h) não apresentaram diferença estatística. A AER de longa duração (n/h, apresentou uma diminuição estatisticamente significativa. O CMM apresentou aumento estatístico. A conclusão do estudo foi que houve diminuição da atividade elétrica de resposta colônica de longa duração e um aumento da atividade motora do cólon esquerdc após a alimentação.

Descritores: Reflexo gastrocólico; Atividade elétrica; Motilidade.


ABSTRACT

Our aim in this study was to settle the patterns of the myoelectric activity on the left colon ( sigmoid) regarding the gastrocolic reflex by analysing the Electric Control Activity (ECA), the Electric Response Activity (ERA), the Migrating Colonic Contractions. We included 15 patients, with no gastrointestinal tract complaints, who underwent histerectomy. The mean age was 40,2 years. Patients were control of themselves and registers were compared with each other before, during and after meal. Bypolar electrodes covered with teflon were implanted on the anterior left colon taenia. After postoperative recovery, data collection was put together. There was taken a DATA Q 200 system for the collection data which reaches frequencies between 0,02 and 10Hz and a software that runs in the Windows environment. Our results showed that there was no significant difference neither in the ECA nor in the short duration ERA ( number/hour) between the groups. The long duration ERA showed a significant decrease regarding its number/hour. There was a statistically significant difference in the Migrating Motor Complex between the registers before and during meal. Regarding the left colon, we concluded that while the electric activity decreased, the motor activity increased after meal.

Key words: Gastrocolic response; Electric activity; Motility.
