Managing a Large Ovarian Cyst During Early Pregnancy: Key Considerations - Obstetrics and Gynecology

At 6 weeks pregnant, an ultrasound examination revealed an 11 cm cyst?


Hello Dr.
Tsao,
My wife is currently 5 to 6 weeks pregnant.
Last Friday, we went for her first prenatal check-up, and it was discovered that she has a large cyst measuring approximately 11 cm x 6 cm, which appears to have a significant amount of black shadowing (possibly liquid).
The doctor suspects it is a chocolate cyst similar to endometriosis, located above the embryo.
Due to its size, the doctor recommends removing the cyst after the embryo reaches 13 weeks of maturity and believes that laparoscopic removal may not be feasible due to the size and potential difficulty of the procedure.
My questions are: Do I need to consider terminating this pregnancy (miscarriage) to address the cyst first? This is our first pregnancy, and it is a very difficult decision.
If we do terminate, will this surgery affect future pregnancies? If we choose to terminate, can we opt for a surgical method that is safer for the mother, such as laparoscopic surgery? I apologize for asking so many questions, and I greatly appreciate your help.

Hello, each physician has different opinions.
In my view, if there are no discomforts, it's best to continue the pregnancy and keep the baby.
Wishing you good health.

Managing a large ovarian cyst during early pregnancy can be a complex and emotionally charged situation, especially when it involves the first pregnancy. Your concerns are valid, and it's important to approach this matter with careful consideration of both maternal and fetal health.


Understanding the Situation
You mentioned that your wife is approximately 5-6 weeks pregnant and that an 11 cm x 6 cm cyst has been detected, which the doctor suspects to be an endometrioma (chocolate cyst). These cysts are often associated with endometriosis and can be filled with old blood. The fact that it is located above the embryo adds another layer of complexity to the situation.


Key Considerations
1. Monitoring the Cyst: In early pregnancy, especially in the first trimester, many cysts can be monitored rather than immediately treated. The recommendation to wait until around 13 weeks for potential surgical intervention is common, as this allows the embryo to develop further and reduces the risk of miscarriage associated with surgery during the early stages of pregnancy.

2. Impact on Pregnancy: Generally, a large ovarian cyst can pose risks such as torsion (twisting of the ovary), rupture, or complications during delivery. However, if the cyst is not causing any immediate symptoms (like severe pain or bleeding), it may be safe to continue the pregnancy while monitoring the cyst's size and condition.

3. Surgical Options: If surgery becomes necessary, the method of removal will depend on the cyst's size, location, and the overall health of the mother and fetus. While laparoscopic (minimally invasive) surgery is often preferred, larger cysts may require an open surgical approach. Your doctor’s recommendation against laparoscopic surgery due to the size of the cyst is not uncommon.

4. Considering Termination: The decision to terminate a pregnancy is deeply personal and should be made with careful consideration of the potential risks and benefits. If the cyst poses a significant risk to your wife's health or the viability of the pregnancy, this option may need to be discussed with your healthcare provider. However, many women with large cysts go on to have healthy pregnancies.

5. Future Fertility: If a decision is made to terminate the pregnancy, it is crucial to discuss with your healthcare provider how this may impact future fertility. Generally, if the surgery is performed carefully and the reproductive organs are preserved, future pregnancies can still be possible. However, each case is unique, and factors such as the underlying cause of the cyst and any additional treatments may play a role.

6. Consulting Specialists: Given the complexity of your situation, it may be beneficial to seek a second opinion from a specialist in maternal-fetal medicine or a reproductive endocrinologist. They can provide additional insights into managing the cyst during pregnancy and the implications for future pregnancies.


Conclusion
In summary, while the presence of a large ovarian cyst during early pregnancy raises valid concerns, it does not automatically necessitate terminating the pregnancy. Close monitoring and a collaborative approach with your healthcare team can help ensure the best outcomes for both your wife and the baby. Open communication with your healthcare provider about your concerns and preferences is essential in making informed decisions that align with your family's goals.
