There are many types of absorbable sutures, various manufacturers are different, the early ones were called sheep’s intestines and the absorbable sutures used today are basically synthetic. Absorbable sutures can be used for knotting and suturing in the abdominal cavity, as well as for suturing at incisions and subcutaneous incisions. The advantage of absorbable sutures is that they do not leave knots in the body, and after they are completely absorbed, there is no foreign body substance in the body. However, the rejection of absorbable sutures is more severe than that of ordinary silk sutures. It is possible that the patient may experience rejection even half a year after discharge from the hospital, even causing infection of the incision, and if necessary, the absorbable suture will have to be removed completely, and the wound will be re-sutured with a new medication.
