Gallstones, uterine fibroids, and pediatric hernias are common conditions that require surgical treatment. Laparoscopic surgery is more effective, but traditional laparoscopic surgery still requires 3-4 holes in the abdominal wall, which will leave several scars, while the emergence of transumbilical single-hole scarless laparoscopic technique solves the above-mentioned regrets by removing the diseased organ easily with only a small hole in the belly button and leaving no scar on the abdominal wall. Traditional surgery for pediatric hernia requires dissecting the hernia sac and freeing the spermatic cord, which causes more damage and leaves a scar in the operated area, resulting in a high recurrence rate, while transumbilical laparoscopic hernia repair only requires a 0.3 cm hole in the navel and can be easily completed with a micro laparoscope as thin as a needle. It is possible to eat and move around on the same day after surgery, and to be discharged from the hospital the next day with better results. This technology was named as one of the “Top Ten Medical Breakthroughs of 2008” by Time Magazine.
