Hello, because the wound of minimally invasive surgery is relatively small, whether it is necessary to remove stitches depends on how the doctor sutures it and what thread to use. If it is sutured with silk thread, the suture can be seen outside the skin and needs to be removed. Generally, it can be removed seven days after operation and will not fall off. If the doctor uses absorbable suture for intradermal suture, that is, cosmetic suture, and the suture cannot be seen outside the skin, it can be absorbed without removing the suture.
