There are 1 or 3 scars for appendicitis surgery, depending on the type of surgery used. A traditional open surgery with a pilot vein will leave a 3-5 cm surgical incision at the location of the McKay’s point. If there is a perforation of the appendix or a large periappendiceal abscess, the incision will be lengthened accordingly, which will facilitate the operation. In case of larger abscesses, a postoperative abdominal drainage tube may need to be threaded next to the incision to observe the internal recovery. Therefore, in the traditional surgical approach, there may be 1 scar or 2 scars, that is, 1 normal surgical incision and 1 scar of drainage tube. With the trans-laparoscopic appendectomy, it is 3 scars, but very faint and very small spots, which are all less than 1 cm long. These 3 scars are the umbilicus, the upper and lower margins of the umbilicus and the antimaculature point, and 1 is the external and external connection between the two. The scar left by the trans-laparoscopy in this area is very large and is an intradermal suture, so the scar is very inconspicuous when applied postoperatively with, for example, silicone gel scar removal medication for a long time, which will have a fading effect.
