Anastomose (do grego anast\u00f3m\u014dsis<\/em> \u2014 abertura) \u00e9 uma conex\u00e3o natural ou criada cirurgicamente entre estruturas anat\u00f4micas ocas, como vasos sangu\u00edneos, ductos linf\u00e1ticos ou se\u00e7\u00f5es de \u00f3rg\u00e3os ocos (por exemplo, o intestino).<\/p>\n\n

As anastomoses naturais desempenham um papel fisiol\u00f3gico importante, proporcionando circula\u00e7\u00e3o sangu\u00ednea colateral (bypass). As anastomoses cir\u00fargicas s\u00e3o criadas para restaurar a continuidade de um \u00f3rg\u00e3o ap\u00f3s a ressec\u00e7\u00e3o de parte dele ou para formar um desvio (shunt).<\/p>\n\n

Classifica\u00e7\u00e3o e princ\u00edpios de forma\u00e7\u00e3o<\/strong><\/h2>\n\n

As anastomoses cir\u00fargicas s\u00e3o classificadas de acordo com o tipo de conex\u00e3o tecidual: “terminal-terminal”, “lateral-lateral” e “terminal-lateral”. O sucesso da sua forma\u00e7\u00e3o e cicatriza\u00e7\u00e3o depende da observ\u00e2ncia de princ\u00edpios cir\u00fargicos rigorosos:<\/p>\n\n

    \n
  • Suprimento sangu\u00edneo adequado para as \u00e1reas a serem unidas.<\/li>\n\n\n\n
  • Sem tens\u00e3o na linha de sutura.<\/li>\n\n\n\n
  • Assegurar a firmeza da conex\u00e3o.<\/li>\n\n\n\n
  • Combina\u00e7\u00e3o cuidadosa de camadas homog\u00eaneas das paredes dos \u00f3rg\u00e3os.<\/li>\n<\/ul>\n\n

    Import\u00e2ncia cl\u00ednica<\/strong><\/h2>\n\n

    A anastomose \u00e9 uma etapa fundamental em cirurgias abdominais, vasculares e oncol\u00f3gicas. A principal e mais perigosa complica\u00e7\u00e3o \u00e9 a falha das suturas da anastomose, que leva ao desenvolvimento de sangramento (em anastomoses vasculares) ou peritonite (anastomose intestinal), sepse e, frequentemente, requer uma nova cirurgia.<\/p>\n\n

    No per\u00edodo p\u00f3s-operat\u00f3rio prolongado pode ocorrer estenose anastom\u00f3tica, ou seja, um estreitamento do tecido cicatricial que prejudica a permeabilidade do \u00f3rg\u00e3o.<\/p>\n\n

    Diagn\u00f3stico diferencial<\/strong><\/h2>\n\n

    \u00c9 importante distinguir uma anastomose de uma f\u00edstula. Uma anastomose \u00e9 uma conex\u00e3o terap\u00eautica formada deliberadamente, enquanto uma f\u00edstula \u00e9 uma passagem patol\u00f3gica que se forma espontaneamente como resultado de doen\u00e7a ou complica\u00e7\u00f5es.<\/p>\n","protected":false},"excerpt":{"rendered":"
