Types of MTP Surgery

Introduction

Medical Termination of Pregnancy (MTP) is a legally and medically approved method to end a pregnancy under specific circumstances. In India, MTP is governed by the Medical Termination of Pregnancy Act, which was first enacted in 1971 and later amended in 2021 to broaden its scope and ensure greater access and safety for women. Abortion, when conducted under professional medical supervision, is both safe and effective. MTP offers an important option for women who face unwanted pregnancies due to health concerns, contraceptive failures, or socio-economic conditions. MTP procedures are generally categorized into two primary approaches: medical abortion and surgical abortion. While medical abortions involve medications, surgical procedures are used when pregnancies are beyond a certain gestational age or when medications are not advisable. Each type of MTP surgery has its own indications, advantages, limitations, and safety considerations.

Choosing the right procedure depends on various factors like the gestational age, the woman’s medical history, and the presence of any complications. Different types of  MTP Surgery are used for terminating a pregnancy, especially when medical management is not suitable or effective.

Types of MTP Surgery

1. Manual Vacuum Aspiration (MVA) :- Manual Vacuum Aspiration is one of the most commonly used methods for terminating early pregnancies, typically up to 12 weeks of gestation. It is a minimally invasive procedure that uses a specially designed manual suction device to remove the contents of the uterus. MVA can be performed in a clinic or hospital setting and is often completed within 15 to 30 minutes. The procedure involves dilating the cervix slightly and then inserting a sterile cannula attached to a hand-held syringe that generates suction. The uterine contents are gently evacuated using negative pressure, without the need for electric-powered equipment. Because of its simplicity, low cost, and high safety profile, MVA is widely used in low-resource settings and is endorsed by the World Health Organization (WHO). Patients often receive a local anesthetic to reduce discomfort. Recovery is usually quick, with minimal complications when performed by trained professionals. MVA is a preferred option for women in early pregnancy who want a surgical method with low risks and fast results.

2. Electric Vacuum Aspiration (EVA) :- Electric Vacuum Aspiration is another surgical option for terminating a pregnancy and is generally suitable for pregnancies up to 12–14 weeks. This method is similar to MVA but uses an electric pump instead of a manual syringe to create the necessary suction. EVA is often preferred in high-volume clinical settings because it is faster and less physically demanding for the provider. The procedure begins with cervical dilation, followed by insertion of a cannula connected to an electric vacuum aspirator. The uterine contents are gently suctioned out, and the entire process usually takes 10–15 minutes. Patients may receive a local anesthetic, conscious sedation, or even general anesthesia depending on the clinical setting and the patient’s preference. Electric Vacuum Aspiration is extremely effective and is associated with a low risk of complications when conducted in a sterile environment by experienced healthcare professionals. Recovery time is short, and most patients can return to their normal activities within a day or two. EVA is particularly suitable in institutional settings where electricity is available, and where speed and efficiency are required.

3. Dilation and Curettage (D&C) :- Dilation and Curettage is a more traditional method of surgical abortion and is typically used for pregnancies up to 15 weeks, though it can also be performed for diagnostic purposes or to manage miscarriage. The procedure involves dilating the cervix and using a surgical instrument called a curette to scrape the lining of the uterus and remove pregnancy tissues. D&C is generally performed under general or regional anesthesia in a hospital setting. Because it involves mechanical scraping, it is considered more invasive than MVA or EVA. The risk of complications like uterine perforation, infections, or damage to the uterine lining is slightly higher, which is why D&C is now less commonly used solely for abortion purposes unless medically indicated. However, D&C may be chosen in cases where other methods are not effective or when a complete evacuation is not achieved through suction alone. It may also be used in combination with other procedures to ensure the uterus is completely emptied. Despite its invasiveness, D&C remains a reliable and effective method when performed by trained specialists and under strict aseptic conditions. Recovery typically involves mild cramping and light bleeding for a few days, and patients are usually discharged the same day.

4. Dilation and Evacuation (D&E) :- Dilation and Evacuation is the preferred surgical method for terminating pregnancies between 13 to 24 weeks. This procedure combines suction and surgical instruments to remove the fetus and other uterine contents. It is often used in second-trimester abortions, which may be necessary due to fetal anomalies, maternal health risks, or delayed diagnosis. The procedure begins with gradual dilation of the cervix, which may take several hours or require medications administered the day before the surgery. Once sufficient dilation is achieved, a combination of vacuum suction and forceps is used to remove the pregnancy tissues. D&E is performed under general or regional anesthesia to ensure patient comfort. D&E requires a skilled provider and is considered safe when done by experienced professionals. However, because the procedure is more complex and involves greater manipulation of the uterus, the risk of complications like bleeding, infection, or injury to the uterus is slightly higher compared to early abortion methods. Despite these risks, D&E is highly effective and often medically necessary for second-trimester terminations. Postoperative care includes monitoring for signs of infection, providing pain relief, and offering emotional support. Most women recover within a few days but may need follow-up consultations for complete recovery and counseling.

Conclusion

Surgical methods of MTP play a crucial role in reproductive healthcare, offering women safe, controlled, and medically supervised options to end a pregnancy when necessary. The choice of procedure depends on several factors, including the gestational age, medical history, patient preference, and available medical facilities. Each type be it MVA, EVA, D&C, or D&E has specific advantages and limitations, but when performed by skilled professionals under sterile conditions, all are considered safe and effective.

Access to legal and safe abortion methods like MTP is fundamental to women’s health and rights. It empowers women to make informed decisions about their reproductive lives while ensuring their physical and emotional well-being. With proper awareness, timely intervention, and compassionate medical care, surgical MTP procedures can be life-saving and liberating, offering a path to healing and renewed hope.
