The surgical scars on the abdomen of patients can be repaired. Different repair methods can often be adopted mainly according to whether the patient belongs to scar body and the size of the scars: i. If the patient does not belong to scar body and the volume of the surgical scars on the abdomen is small, at this time, external application of Ruyi Jinhuang cream and Xizheto ointment and appropriate massage can be used to improve the blood circulation at the scars and promote the softening and absorption of the scar tissue by itself. After active treatment, most patients can have their local scars completely faded in 2-3 months, and the treatment effect is better. Second, if the volume of abdominal scars is large and the patient belongs to scar body, in this case, simple external drug physiotherapy is not able to make the scars absorb and subside by themselves. Liquid nitrogen freezing and laser cauterization can be used to make the scar tissue coagulate and necrosis to fall off by itself. If necessary, surgical treatment can be used to remove the fibrous tissues from the scars and use intradermal suturing to remove the surgical scars.
