Abstract: RACIONAL: A doen a do refluxo gastroesofágico é uma das enfermidades do trato gastrointestinal mais frequentes atualmente. A fundoplicatura de Nissen-Rossetti é técnica operatória muito empregada para o tratamento cirúrgico, sendo a migra o intratorácica da válvula uma das principais complica es. OBJETIVO: Avaliar a incidência da migra o da fundoplicatura e seus fatores de risco. MéTODO: Analisou-se retrospectivamente 207 prontuários de pacientes submetidos à fundoplicatura videolaparoscópica pela técnica de Nissen-Rossetti para tratamento da doen a do refluxo. As variáveis analisadas foram: sexo, idade, esofagite, grau de esofagite, tamanho da hérnia, alargamento da cárdia, encurtamento esofágico. Para as variáveis quantitativas, foi considerado o teste t de Student. Para as nominais, foi considerado o teste de Qui-quadrado ou o teste exato de Fisher. Valores de p<0,05 indicaram significancia estatística. RESULTADOS: Do total, 135 eram mulheres (65,22%) e 72 homens (34,78%), com média de idade de 47,43 anos. O tamanho da hérnia variou entre 2 e 6 cm. Duzentos pacientes tinham esofagite (96,62%), sendo 113 (56,50%) grau I, 75 grau II (37,50%) e 12 grau III ou IV (6%). Alargamento de cárdia e es fago de Barrett foram vistos em 153 (73,91%) e 13 (6,28%) casos, respectivamente. Um paciente apresentava encurtamento esofágico. Dentre as mulheres, 33 (24,4%) apresentaram migra o e entre os homens, apenas seis (8,3%) (p = 0,005). A idade média dos pacientes com e sem migra o foi de 54,03 e 45,89 anos, respectivamente (p = 0,001). CONCLUS O: A incidência da migra o da fundoplicatura foi de 18,8%. O gênero feminino e possuir maior idade influenciam na probabilidade dessa migra o. O grau de esofagite, tamanho da hérnia e alargamento da cárdia n o se mostraram fatores de risco para migra o intratorácica da fundoplicatura.

Abstract: As altera es funcionais da motilidade antroduodenal ainda n o foram bem caracterizadas até a presente data. O marca-passo gástrico, possivelmente localiza-se junto à grande curvatura, próximo ao fundo gástrico. A partir dele, ondas de despolariza o dirigem-se ao est mago, duodeno e às demais partes do intestino delgado. OBJETIVO: Avaliar a influência do marca-passo gástrico sobre a motilidade gastroduodenal em c es. MéTODOS: O protocolo experimental constou de três etapas. Na primeira, realizou-se esofagostomia cervical seguida de manometria antroduodenal eletr nica e pH-metria em 20 c es (grupo controle), durante 4 horas. Na segunda etapa, realizou-se a ressec o de parte do fundo gástrico e da área do marca-passo gástrico, com técnica videolaparoscópica. Na terceira, decorridos três meses, repetiu-se a manometria antroduodenal e a pH-metria gástrica. RESULTADOS: No grupo controle observou-se tra ado típico de motilidade antroduodenal, com complexo interdigestivo de motilidade (IMC) com fases 1, 2 e 3; na pH-metria, observou-se padr o de acidez com linha de base em pH de 1,15. Após a ressec o gástrica parcial, a manometria apresentou, no geral, aumento na freqüência de contra es, aumento da participa o relativa da fase 2 e diminui o da participa o relativa da fase 3. No pH gástrico, observou-se aumento no percentual de pH 0 - 1 e pH 1 - 2, bem como diminui o na porcentagem de pH 6 - 7, com conseqüente diminui o do pH gástrico e redu o no tempo prandial. CONCLUS O: Pela retirada da área do marca-passo gástrico ocorreram altera es de motilidade antroduodenal, permanecendo porém a ocorrência de IMC's completos.
