Post-operative concerns after suture removal?


Hello, doctor.
I would like to ask about an injury I sustained due to work.
My left thumb was struck by a metal plate, resulting in a fracture of the nail area.
I was injured on December 23, 2023, and had my stitches removed on January 12, 2024.
It wasn't until the scab fell off on March 2, 2024, that I discovered there is still a 3 cm long piece of suture left.
Do I need to undergo another surgery to have it removed?

Xiao Wen, 30~39 year old female. Ask Date: 2024/03/02

Dr. Li Zhonghuai reply Surgery

Take care! Changhua Hospital cares about you!

It sounds like you have been through quite an ordeal with your injury and subsequent surgery. The presence of a remaining stitch or suture after a surgical procedure can understandably cause concern. Here’s a detailed response to your question regarding the remaining stitch and what steps you might consider taking.

First, it’s important to understand that sutures are used to hold tissues together during the healing process. In many cases, sutures are absorbable, meaning they dissolve on their own over time. However, if the sutures are non-absorbable, they need to be removed by a healthcare professional. If you have discovered a 3 cm long stitch that was not removed during your follow-up appointment, it is advisable to consult with your surgeon or a healthcare provider as soon as possible.

Here are some considerations regarding the remaining stitch:
1. Assessment of the Stitch: The first step is to assess whether the stitch is causing any pain, irritation, or signs of infection (such as redness, swelling, or discharge). If the stitch is protruding from the skin and causing discomfort, it may need to be removed. If it is not causing any problems, it might be safe to leave it, but this should be evaluated by a medical professional.

2. Consulting a Healthcare Provider: It is crucial to contact your surgeon or a healthcare provider to discuss your concerns. They can evaluate the situation and determine whether the stitch needs to be surgically removed. If the stitch is embedded in the tissue, they may need to perform a minor procedure to extract it.

3. Potential Risks: Leaving a non-absorbable stitch in the body can lead to complications such as infection, inflammation, or the formation of a granuloma (a small area of inflammation). In some cases, the body may eventually expel the stitch on its own, but this is not guaranteed and can lead to discomfort.

4. Follow-Up Care: If you are advised to have the stitch removed, the procedure is typically straightforward and can often be done in an outpatient setting. After removal, your healthcare provider may give you specific instructions for care, including how to clean the area and signs to watch for that might indicate complications.

5. Healing Process: If the stitch is removed, your healthcare provider will also assess the healing of the surrounding tissue. It’s important to follow any post-operative care instructions to ensure proper healing.

In summary, it is advisable to seek medical attention regarding the remaining stitch. While it may not always require surgical intervention, a healthcare professional can provide the best guidance based on your specific situation. Remember, it’s always better to err on the side of caution when it comes to post-surgical concerns. Your health and comfort should be the priority, so don’t hesitate to reach out for help.
