I remember a period of time when I don't know where it started. Some patients were extremely afraid of sutures. Before any surgery, no matter how big or small, they would pester the doctor and ask him to give them good sutures that could be absorbed by the human body. These people were afraid of leaving foreign objects in their bodies. I don't know where they heard the rumor that leaving these sutures in the body would kill people.
It is obvious that this statement is impossible. Absorbable sutures were invented later. According to this statement, all the patients who underwent surgery before were killed by non-absorbable sutures.
When considering which suture to use in medicine, the first thing the doctor should think about is not whether the suture can be absorbed by the human body, but the tensile strength of the suture material.
Regarding the tension of human tissue, we have talked about it since the first surgery using a retractor. After anesthesia, as long as the tissue is alive and moving, there will always be contraction tension.
In medicine, sutures are used to close wounds in order to pull the two ends of the wound together to allow the wound to heal. If the suture tension is not strong enough, it will not be able to resist the contraction tension of human tissue. In this way, when the human tissues on both sides of the anastomosis repeatedly contract, this tension can easily directly break the thread, causing the wound to split again, resulting in suture failure.
How terrible is a failed suture? If the wound is opened again, won't it cause heavy bleeding? Or will it leak fluid? The wound never heals, the anastomosis leaks, and there are repeated infections and systemic sepsis. It's really a death sentence - all the doctors can think of are these more terrifying things.
Some patients are afraid of rumors that leaving sutures in the body can kill people. If it refers to suture infection, now all sutures are strictly sterilized and the incidence rate is too low. And if non-absorbable sutures have the risk of infection, absorbable sutures also have the risk of infection. Absorbable sutures are not absorbed by the body immediately after being sewn, which would make the suture meaningless. It has to wait until the wound heals before being absorbed by the body. This process can be as short as a few days or as long as more than a month.
What these patients are actually afraid of is the rejection of sutures. The problem is that medical technology has already developed to the point where there are strict regulations on the use of various surgical materials, and there are clear signs of which ones cannot be left in the human body and which ones can remain in the human body for a long time. All materials that can remain in the human body must undergo tests and studies on their compatibility with human tissues, and can only be used clinically after passing the review. This has been discussed in orthopedic materials. Complex orthopedic materials can do this, and small sutures have long crossed this threshold.
Having said that, it can be seen that these people's concerns are nonsense.

Indeed, in clinical practice, some doctors will ask patients whether to use absorbable sutures before surgery. Where are these sutures that can be selected by patients generally used? They are not harmful to the skin layer, which is not very important to the patient's life. After all, some patients are financially constrained and can only afford limited medical expenses. In those days, these absorbable sutures were called cosmetic sutures and were very expensive and had to be paid for by the patient.
When it comes to the choice of sutures, which concerns the patient's life, it is impossible for a doctor to hand over such a professional matter to a patient who does not understand medicine to make the choice on his own. That is equivalent to handing a knife to someone to commit suicide.
Back to polypropylene thread, it is most commonly used in blood vessels.
The advantage of this single-strand thread is that it is less susceptible to infection than multi-strand threads. Its smoothness causes less damage when passing through human tissue, and it has a low rejection response when it stays in the human body for a long time.
