Suture Techniques: What to Expect After Fistula Surgery - Surgery

Suture therapy


Hello Dr.
Ke, I underwent a fistula surgery on May 30 (Monday) and the string method was used.
However, isn't it supposed to take at least four weeks for the tube to fall out? Today is June 4 (Saturday), and it has only been five days, and it has already fallen out.
Is this abnormal?

The meaning of thread therapy is to pass several threads through the fistula, and then tie them off one by one in the outpatient setting.
There should not be any tubes present.
Some people also pass a rubber tube underneath the threads to protect the underlying tissue.
Since I did not perform the surgery myself, I am unsure if the tube falling out at this time is normal.
It would be better to have the surgeon check it again.

After undergoing fistula surgery, particularly with the use of suture techniques like the "string method" (串線療法), it is essential to understand what to expect during the recovery process. Your concern about the suture falling out earlier than expected is valid, and I will address your questions based on medical knowledge and common practices in post-operative care.

1. Suture Duration and Expectations: Typically, sutures used in fistula surgeries are designed to remain in place for a specific duration to allow adequate healing. In many cases, sutures are expected to dissolve or be removed within a few weeks, depending on the type of suture material used and the specific surgical technique. If your suture fell out just five days post-surgery, it may not necessarily indicate a problem, but it does warrant further evaluation. It's important to consider whether the suture was absorbable or non-absorbable, as absorbable sutures are designed to dissolve over time.

2. Signs of Complications: After fistula surgery, you should monitor for any signs of complications, such as increased pain, swelling, redness, or discharge from the surgical site. If you experience any of these symptoms, it is crucial to contact your healthcare provider promptly. The early loss of a suture could potentially lead to issues such as wound dehiscence (the reopening of the surgical wound) or infection, especially if the wound is not adequately closed.

3. Healing Process: The healing process after fistula surgery can vary significantly from person to person. Factors such as the size and location of the fistula, your overall health, and adherence to post-operative care instructions can all influence recovery. It is common for patients to experience some discomfort and changes in the surgical area as healing progresses.
4. Follow-Up Care: It is essential to attend all follow-up appointments with your surgeon or healthcare provider. They will assess the healing process and determine if any further intervention is necessary. If the suture has fallen out prematurely, your doctor may need to evaluate the site to ensure that healing is proceeding as expected and that there are no complications.

5. Post-Operative Instructions: Following your surgeon's post-operative care instructions is vital for a successful recovery. This may include keeping the area clean and dry, avoiding strenuous activities, and monitoring for any signs of infection. If you have any concerns about your recovery or the condition of the surgical site, do not hesitate to reach out to your healthcare provider for guidance.

In summary, while the early loss of a suture after fistula surgery can be concerning, it is not always indicative of a problem. However, it is crucial to monitor the surgical site for any signs of complications and to maintain open communication with your healthcare provider. They will be able to provide the most accurate assessment and recommendations based on your specific situation. Remember, every patient's recovery journey is unique, and your healthcare team is there to support you through the process.

Fistula surgery will use absorbable sutures, which may come loose if there is significant tension on the wound; this is normal as long as there is no excessive bleeding. No urgent intervention is required. If the suture is hanging outside, avoid pulling on it. You can carefully t...
