Introduction

Posterior colpotomy is a procedure in which fluid is withdrawn from the posterior fornix for examination. It is commonly used clinically to diagnose and treat conditions such as pelvic masses and pelvic effusion. During the procedure, accurate placement of the puncture site is essential to avoid injury to the uterus or intestines. To prevent bodily harm, it is recommended that the procedure be performed under the guidance of a qualified physician. After the procedure, maintain a light diet and avoid spicy or irritating foods.

Generally, posterior fornix puncture is a procedure in which fluid is drawn from the vaginal fornix for examination. Clinically, it is commonly used to diagnose and treat conditions such as pelvic masses and pelvic effusion. The specific steps are as follows:

1. Position the patient in the lithotomy position, disinfect the external genitalia, and administer local anesthesia.

2. After the anesthesia has taken effect, use a vaginal speculum to expose the cervix and vaginal fornices, then disinfect the area again.

3. Use cervical forceps to grasp the posterior lip of the cervix and pull it forward to fully expose the posterior fornix of the vagina.

4. Using a specialized needle, insert it into the center of the posterior fornix, approximately 1 cm below the junction of the cervical and vaginal mucosa, advancing parallel to the cervical canal.

5. Once the needle passes through the vaginal wall and a sensation of "loss of resistance" is felt, immediately aspirate using the syringe. If no fluid is obtained, slowly withdraw the needle while continuing to aspirate.

6. After aspiration is complete, remove the needle.

During the procedure, ensure accurate placement of the puncture site to avoid injury to the uterus or intestinal tract. To prevent bodily harm, this procedure should be performed under the guidance of a qualified physician. After the procedure, maintain a light diet and avoid spicy or irritating foods.
