Dilation and Curettage, and Future Pregnancy

Introduction

Dilation and curettage (D&C) is a procedure undertaken to effectively remove the uterine lining following a miscarriage or abortion. Following this procedure, women often proceed with planning for future pregnancies. There are chances for conception again, it is important to note that associated complications may affect subsequent pregnancies. It is to be understood that the implications of D&C are not uniform across all individuals, as they can be influenced by a range of other factors as well.

What Is Dilation and Curettage?

Dilation and curettage, commonly known as D&C, is a surgical procedure where the cervix is dilated, and a slender instrument is introduced into the uterus to remove tissue from its inner lining; this process is referred to as curettage. D&C serves both diagnostic and therapeutic purposes, particularly in cases of abnormal uterine bleeding or suspected uterine abnormalities. It is also done to remove pregnancy tissue in miscarriage or first-trimester abortion. D&C can be a preparatory step before a hysterectomy, utilizing a slender illuminated scope to visualize the uterine interior. The procedure is typically conducted by a healthcare professional in a hospital or surgical center setting.

The procedure involves the insertion of laminaria, a slender rod made from natural or synthetic materials, into the cervix to gently expand the opening of the cervix. In some cases, medications may be administered to soften the cervix, sometimes accompanied by anesthesia to ensure patient comfort. A specialized instrument called a curette is introduced, facilitating the removal of the uterine lining tissue. Also, vacuum aspiration or suction curettage might be done in the procedure.

Complications are infrequent; they can include bleeding, infection, or unintended uterine perforation due to the instrumentation. After the procedure, patients can return home within a few hours and can resume their regular activities within one to two days.

What Are the Complications Following Dilation and Curettage?

Dilation and curettage (D&C) typically have low complication rates, but potential risks include:

• Uterine Perforation: In some cases, the surgical instrument may accidentally perforate the uterus. This risk is higher in women who have been pregnant recently or are in menopause.

• Cervical Damage: The cervix could tear during the procedure, leading to bleeding. This may require medications or sutures to stop bleeding and promote healing. Dilation using rigid dilators can result in cervical trauma.

• Asherman's Syndrome: Scar tissue formation within the uterus, known as Asherman's syndrome, can occur after D&C, particularly following miscarriage or delivery.

• Infection: While rare, infections can develop following D&C.

• Prolonged Pain and Cramps: Some individuals might experience heightened pain and abdominal cramps lasting beyond 48 hours post-procedure.

It is important to note that these complications are infrequent, and D&C is generally a safe procedure.

Does Dilation and Curettage Affect Future Pregnancy?

• Asherman's Syndrome: It is a condition that can develop as a consequence of Dilation and Curettage (D&C). This syndrome is characterized by the formation of scar tissue following the procedure. These scar tissues tend to adhere and unite, effectively partitioning the uterus into sections and reducing the total uterine volume. This condition can manifest with varying intensity, ranging from mild to severe, and potentially lead to the absence of menstrual cycles and infertility. Asherman's syndrome has two primary symptomatic presentations:

1. Lack of Menstrual Cycle: One key symptom involves the absence of regular menstrual cycles. The scar tissue can disrupt the normal uterine lining shedding process, resulting in the irregular or complete absence of periods.
2. Impaired Uterus for Implantation: Another significant symptom relates to the uterus's compromised ability to facilitate embryo implantation. The scar tissue can create an environment unsuitable for successful embryo attachment, potentially leading to infertility.

• Undergoing dilation and curettage will not affect the ability to get pregnant again. Dilation and curettage may increase the risk of experiencing a preterm delivery in a future pregnancy.

• It is found that the rate of preterm birth increases among women who had a history of dilation and curettage for first-trimester miscarriage of pregnancy termination.

• This can be prevented by adopting non-invasive management techniques and adopting medical management in case of termination of pregnancy.

• A rise in postpartum hemorrhage was reported among patients with a prior history of dilation and curettage.

• Dilation and curettage cause miscarriage, cervical incompetence, or preterm birth in subsequent pregnancies.

• It should be noted that not all pregnancies following a D&C will result in complications. The chances vary depending on the health of the women and how the D& C procedure was carried out.

• The decision to undergo D&C should be made considering all the factors and reducing all the possible associated risks. The risk for future pregnancies or infertility depends on the medical condition, the health of the patient, how well the procedure is carried out, and how the body organs react to the procedure. Dilation and curettage do not have an important role in future fertility. Proper conversation with the health care professional and taking suggestions related to future pregnancy should be cleared.

How to Reduce the Risk Following Dilation and Curettage?

• After an incomplete or missed abortion, assess outcomes before going ahead with surgical Management.

• Non-surgical methods offer safe and effective alternatives with minimal short- and long-term complications.

• Opting for a conservative approach reduces healthcare risks. Patients widely accept and find satisfaction in conservative management.

• Patients should be given the choice to select treatment after being informed about risks and alternatives.

• If surgical management is chosen, premedication using cytotec and laminaria placement to dilate the cervix helps minimize mechanical cervical injury.

• Proper follow-up after the procedure. Look for any unusual signs and symptoms. If any, report to the doctor immediately.

• Seek medical help while planning for future pregnancy.

Conclusion

Dilation and curettage is a diagnostic and therapeutic procedure that involves the removal of the uterine lining for diagnostic purposes or after a miscarriage or abortion. D&C should only be performed when necessary, carefully considering the patient's health and the procedure's safety.

Patients should be provided with comprehensive information about the procedure and its associated risks, allowing them to make informed choices about the treatment. Opting for non-surgical or conservative surgical methods provides favorable outcomes with minimal complications.

It is not always true that dilation and curettage can affect the future pregnancy. There are chances that it can pose some risk, and it depends upon the health of the patient and how well the body reacts to the previous dilation and curettage procedure.
