What is ectopic pregnancy puncture

Many people may not be so clear about the examination method of ectopic pregnancy puncture. In fact, the effect of this examination is relatively good and can reduce the chance of misdiagnosis. However, some drugs still need to be injected locally after the puncture. In this way, we can better understand the specific cause of ectopic pregnancy. Only after the cause of the disease is found can targeted treatment be given, which makes the chance of improvement relatively greater.

Indications

1. If there is suspected fluid, blood or pus in the pelvic cavity, a puncture and fluid extraction examination can be performed to understand the nature of the effusion.

2. Puncture drainage and local injection of drugs for pelvic abscess.

3. During delivery, if an ovarian cyst is found to be incarcerated in the pelvic cavity and hinders delivery, after excluding malignancy, emergency puncture can be performed to extract the cyst fluid and allow the fetal presenting part to descend naturally. If conditions permit, a cesarean section and cystectomy should be performed.

4. If the pelvic mass is located in the rectouterine fossa, puncture the posterior fornix and directly aspirate the contents of the mass for smear and cytological examination. If a malignant tumor is highly suspected, puncture should be avoided. Once the puncture is diagnosed as malignant, surgery should be performed promptly.

5. After an ectopic pregnancy ruptures, blood from the abdominal cavity can be drawn from the posterior fornix to confirm the diagnosis.

Contraindications

Puncture is contraindicated for women who have no sexual life, those who are clinically highly suspected of having a malignant tumor, women who are menstruating, those with inflammatory adhesions on the posterior wall of the uterus, and those with severe pelvic adhesions.

Surgical procedures

The general steps of the surgery:

1. Take the lithotomy position.

2. Use a vaginal speculum to expose the cervix and vaginal vault.

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

4. Between the posterior lip of the cervix and the posterior wall of the vagina, insert 2 to 3 cm in a direction parallel to the cervix and slightly backward, and then aspirate.

5. After suction is completed, remove the needle.

Postoperative complications

Injury to the uterus or rectum.

Precautions

During the operation, pay attention to the accuracy of the puncture site and avoid injuring the uterus and intestines.

Postoperative diet

Eat a light diet and avoid raw, cold, spicy and greasy foods.

Posterior vaginal fornix puncture is a simple and important diagnostic operation commonly used in gynecological clinic. It is mainly used to understand whether there is fluid accumulation in the rectouterine fossa and its nature; or to be used to closely follow the characteristics of the contents of the rectouterine fossa, so as to explore the cause and make a clear diagnosis. Occasionally it is also used to treat certain diseases.
