Minimally invasive surgery for appendicitis are relatively small, mainly because most of them are operated by single-hole laparoscopy, where a poke card incision of about 1 cm is made around the navel and the appendix can be completely removed through the main operating hole. Since the incision is made in the folds of the skin around the navel, the scar is not very visible and does not affect the aesthetics. For patients who require cosmetic results, scar formation can be prevented by actively preventing infection after surgery, and also by applying scarling or some scar patches during the recovery period. For patients with hyperplastic scars, surgical excision or laser polishing can also be used for secondary treatment of the surgical scars, which can effectively reduce or minimize the surgical scars.
