Post-Thyroidectomy Care: Key Questions on Imaging and Infection Management - Surgery

After total thyroidectomy


Hello, Doctor.

1.
I had a contrast agent injection in the emergency room of Far Eastern Memorial Hospital on June 3 for a hematoma check after a total thyroidectomy.
I would like to know how long I need to wait before undergoing a lung examination that requires another contrast agent injection.
2.
After undergoing minimally invasive total thyroidectomy on May 27, I developed a postoperative infection near the Adam's apple, where there was a previous lump.
It was painful when I pressed on it with my fingernail, but the lump has decreased in size, and the hematoma has resolved.
Could this be caused by a bacterial infection? Should I see an otolaryngologist for an endoscopic examination, or should I consult an infectious disease specialist or a hematologist-oncologist?
3.
On June 7, I visited the rehabilitation department at Far Eastern Memorial Hospital for a cervical spine X-ray.
During the rehabilitation session, I underwent traction, which caused some pain in my neck.
Is it appropriate to undergo this treatment so soon after surgery?
4.
I would like to go to the rehabilitation department at Fu Jen Catholic University Hospital for an examination.
Is it possible to have an X-ray done there? Will there be any radiation exposure?
5.
After completing the iodine-131 scan on July 5, I would like to have a liver ultrasound.
Will this affect my health in any way?
Thank you for your assistance.

Hello, Cool Dragon.

1.
Since you are scheduled for iodine-131 treatment on July 18, if you need to receive a contrast agent, you should wait until after the treatment is completed.

2.
It is difficult to determine whether it is a bacterial infection based on your description; you should consult the doctor who initially treated you.
It seems more like a hematoma or an infection.
Since you have already experienced relief, if you are not feeling uncomfortable, observation is sufficient.
Surface lumps cannot be examined with an endoscope; they can only be visualized with an external ultrasound.

3.
It has been a month since your surgery; using a rehabilitation brace should be fine as long as it does not pull on the wound.

4.
X-rays involve radiation, so they should only be taken when the doctor truly believes it is necessary.

5.
Ultrasound does not have any adverse effects on the body.

Post-thyroidectomy care is crucial for ensuring a smooth recovery and monitoring for any complications. Your questions touch on several important aspects of post-operative management, including imaging studies, potential infections, and rehabilitation. Let's address each of your concerns in detail.

1. Timing for Imaging Studies Post-Contrast Administration: After receiving a contrast agent for imaging, such as during your thyroidectomy, it is generally advisable to wait at least 48 hours before undergoing another imaging study that requires contrast. This waiting period allows your body to clear the contrast material and reduces the risk of any potential adverse reactions. If you are planning to have a lung scan that requires contrast, consult with your healthcare provider to ensure that the timing is appropriate based on your specific situation.

2. Post-Surgical Infection Concerns: The presence of a painful lump near your throat after thyroid surgery could indicate a hematoma or an infection. Since you mentioned that the lump has decreased in size, this could be a positive sign. However, it is essential to monitor for symptoms such as increased redness, warmth, or discharge, which could indicate an infection. If you suspect a bacterial infection, it would be prudent to consult with an ENT specialist, as they can perform a thorough examination and may use an endoscope to visualize the area more clearly. If the infection is confirmed or suspected to be severe, a referral to an infectious disease specialist may also be warranted.

3. Rehabilitation and Physical Therapy: After thyroid surgery, it is common to experience some discomfort, especially when engaging in physical therapy or rehabilitation exercises. If you are experiencing pain during neck exercises, it is crucial to communicate this to your physical therapist. They can modify your rehabilitation program to accommodate your recovery stage. Generally, light stretching and gentle movements are encouraged, but any activity that causes significant pain should be avoided until you have healed further.

4. X-ray and Radiation Exposure: X-rays do involve exposure to radiation, but the amount is typically low and considered safe for most patients. If your healthcare provider deems an X-ray necessary for your recovery, it is usually because the benefits outweigh the risks. If you have concerns about radiation exposure, discuss them with your physician, who can provide reassurance and explain the necessity of the imaging.

5. Post-I-131 Treatment Imaging: After receiving radioactive iodine (I-131) treatment, it is generally safe to undergo an abdominal ultrasound. Ultrasound does not involve radiation and poses no risk to your health. It is a non-invasive imaging technique that can help assess your liver or other abdominal organs without any adverse effects related to your previous treatment.

In summary, post-thyroidectomy care involves careful monitoring for complications, appropriate timing for imaging studies, and effective management of any potential infections. Always keep an open line of communication with your healthcare providers, and do not hesitate to seek further evaluations if you have concerns about your recovery. Regular follow-ups are essential to ensure that any issues are addressed promptly, and your overall health is maintained.
