L’anastomose (du grec anast\u00f3m\u014dsis<\/em>, \u00ab ouverture \u00bb) est une connexion naturelle ou cr\u00e9\u00e9e chirurgicalement entre des structures anatomiques creuses, telles que les vaisseaux sanguins, les canaux lymphatiques ou certaines parties d’organes creux (par exemple, l’intestin).<\/p>\n\n

Les anastomoses naturelles jouent un r\u00f4le physiologique important en assurant une circulation sanguine collat\u00e9rale (pontage). Les anastomoses chirurgicales sont r\u00e9alis\u00e9es pour r\u00e9tablir la continuit\u00e9 d’un organe apr\u00e8s la r\u00e9section d’une partie de celui-ci ou pour former un pontage (shunt).<\/p>\n\n

Classification et principes de formation<\/strong><\/h2>\n\n

Les anastomoses chirurgicales sont class\u00e9es selon le type de connexion tissulaire\u00a0: \u00ab\u00a0bout \u00e0 bout\u00a0\u00bb, \u00ab\u00a0c\u00f4t\u00e9 \u00e0 c\u00f4t\u00e9\u00a0\u00bb et \u00ab\u00a0bout \u00e0 c\u00f4t\u00e9\u00a0\u00bb. Le succ\u00e8s de leur formation et de la gu\u00e9rison d\u00e9pend du respect de principes chirurgicaux stricts\u00a0:<\/p>\n\n

    \n
  • Une irrigation sanguine ad\u00e9quate des zones \u00e0 connecter.<\/li>\n\n\n\n
  • Pas de tension sur la ligne de raccord.<\/li>\n\n\n\n
  • Garantie de la bonne \u00e9tanch\u00e9it\u00e9 de la connexion.<\/li>\n\n\n\n
  • Alignement minutieux des couches homog\u00e8nes des parois de l’organe.<\/li>\n<\/ul>\n\n

    Importance clinique<\/strong><\/h2>\n\n

    L’anastomose est une \u00e9tape cl\u00e9 dans la chirurgie abdominale, vasculaire et oncologique. La complication principale et la plus dangereuse est la d\u00e9faillance des sutures de l’anastomose, qui entra\u00eene l’apparition d’h\u00e9morragies (anastomoses vasculaires) ou de p\u00e9ritonites (anastomoses intestinales), une septic\u00e9mie, et qui n\u00e9cessite souvent une nouvelle intervention chirurgicale.<\/p>\n\n

    Au cours de la p\u00e9riode postop\u00e9ratoire \u00e0 long terme, une st\u00e9nose anastomotique peut se d\u00e9velopper. Il s’agit d’un r\u00e9tr\u00e9cissement du tissu cicatriciel qui alt\u00e8re la perm\u00e9abilit\u00e9 de l’organe.<\/p>\n\n

    Diagnostic diff\u00e9rentiel<\/strong><\/h2>\n\n

    L’anastomose ne doit pas \u00eatre confondue avec une fistule. Une anastomose est une connexion th\u00e9rapeutique form\u00e9e d\u00e9lib\u00e9r\u00e9ment, tandis qu’une fistule est un passage pathologique qui se forme spontan\u00e9ment \u00e0 la suite d’une maladie ou de complications.<\/p>\n","protected":false},"excerpt":{"rendered":"
