Culdocentesis - Overview

Definición:

Es un procedimiento para verificar la existencia de líquido anormal en el espacio justo detrás de la vagina (fondo de saco).

Forma en que se realiza el examen:

Primero, se realiza un examen pélvico. Luego, el médico sostendrá el cuello uterino con un instrumento y lo levantará ligeramente.

Se inserta una aguja larga y delgada a través de la pared vaginal, justo debajo del útero, y se toma una muestra de cualquier líquido que se encuentre en ese espacio. Luego se extrae la aguja.

Preparación para el examen:

A usted le pueden solicitar que camine o permanezca sentada durante un tiempo corto antes de realizar el examen.

Lo que se siente durante el examen:

Se puede experimentar una sensación molesta de calambres cuando se agarra el cuello uterino. Asimismo, se presenta un dolor agudo y breve a medida que se inserta la aguja.

Razones por las que se realiza el examen:

Este procedimiento se realiza cuando hay dolor en el abdomen bajo y en la pelvis, y cuando otros exámenes sugieren que puede haber líquido en el fondo de saco. Igualmente, se puede realizar cuando el médico sospecha de ruptura de un embarazo ectópico o un quiste ovárico.

En la actualidad, este procedimiento rara vez se hace, debido a que el líquido en el fondo de saco generalmente se puede detectar con una ecografía.
