Risks of Cyst Removal Surgery: What You Need to Know - Dermatology

Excision of the tumor?


Hello Dr.
Wu, I apologize for bothering you again! A few days ago, I underwent a cyst removal surgery at the dermatology department of the hospital.
Before the surgery, I asked the attending physician about any risks, and the doctor replied that it was just a minor procedure and to be cautious about avoiding infection afterward.
However, I later realized that the surgery was performed in the dermatology treatment room, and there was no blood test conducted beforehand.
I would like to ask you: 1.
Hair transplant procedures typically require blood tests to check for HIV, but why is there no blood test required for a cyst removal surgery? 2.
Is there a risk of infection, such as HIV or other viruses, when undergoing a cyst removal surgery without a blood test? After all, we ordinary people do not know if the surgical instruments were thoroughly sterilized.
Thank you for your clarification, I greatly appreciate it.

Generally, cyst surgery does not require blood tests.
Additionally, I cannot understand why you suspect that the surgical instruments were not sterilized.
In Taiwan, whether in clinics or hospitals, sterilization of instruments is a fundamental practice.

When it comes to cyst removal surgery, understanding the associated risks and precautions is crucial for ensuring a safe and successful outcome. Cyst removal, often considered a minor surgical procedure, typically involves excising a benign growth from the skin or underlying tissue. However, even minor surgeries carry inherent risks that patients should be aware of.

1. Preoperative Testing: Generally, blood tests are not routinely required for minor procedures like cyst removal unless there are specific concerns about the patient's health or medical history. For instance, if a patient has a history of bleeding disorders or other significant health issues, preoperative blood work may be warranted. In the case of hair transplant surgeries, blood tests are often performed to rule out infectious diseases, including HIV, due to the nature of the procedure and the potential for blood exposure. However, for a straightforward cyst removal, the necessity for blood tests is less common unless indicated by the patient's medical history.

2. Infection Risks: The risk of infection is a concern with any surgical procedure, including cyst removal. While the likelihood of contracting a virus such as HIV from a properly performed cyst removal is extremely low, it is not entirely absent. The primary risk of infection arises from the surgical site itself, particularly if proper sterile techniques are not followed. Healthcare facilities are required to adhere to strict sterilization protocols for surgical instruments to minimize the risk of infection. If you have concerns about the sterilization practices at the facility where your procedure was performed, it is advisable to discuss these with your healthcare provider.

3. Postoperative Care: After cyst removal, patients should be vigilant about monitoring the surgical site for signs of infection, which may include increased redness, swelling, warmth, or discharge. Keeping the area clean and following the surgeon's postoperative care instructions is essential for minimizing infection risks. If any unusual symptoms arise, such as fever or excessive pain, patients should seek medical attention promptly.

4. Complications: While complications from cyst removal are rare, they can occur. Potential complications include:
- Infection: As mentioned, this is a primary concern. Proper wound care is essential.

- Scarring: Depending on the size and location of the cyst, scarring may occur post-surgery.

- Recurrence: In some cases, cysts may recur if the entire cyst wall is not removed during the procedure.

- Nerve Damage: If the cyst is located near nerves, there is a slight risk of nerve damage, which could lead to numbness or tingling in the area.

5. Follow-Up: It is important to attend any scheduled follow-up appointments to ensure proper healing and to address any concerns that may arise post-surgery. During these visits, your healthcare provider can assess the surgical site and provide guidance on further care.

In conclusion, while cyst removal is generally a safe procedure with minimal risks, it is essential to be informed about potential complications and the importance of postoperative care. If you have specific concerns about the procedure you underwent, including the lack of blood tests or sterilization practices, it is advisable to discuss these with your healthcare provider for reassurance and clarity. They can provide you with the most accurate information tailored to your situation and help alleviate any concerns you may have.
