Anastomosis

Definición

Es una conexión quirúrgica entre dos estructuras. Generalmente quiere decir una conexión creada entre estructuras tubulares, como los vasos sanguíneos o las asas del intestino.

Por ejemplo, cuando se extirpa quirúrgicamente parte de un intestino, los dos extremos restantes se cosen o se unen con grapas (se anastomosan) y el procedimiento se denomina anastomosis intestinal.

Información

Los ejemplos de anastomosis quirúrgicas son:

  • La fístula arteriovenosa (una abertura creada entre una arteria y una vena) para diálisis.
  • La colostomía (una abertura que se crea entre el intestino y el abdomen).
