Laparoscopic cholecystectomy has become a routine treatment for gallbladder stones, cholecystitis, and gallbladder polyp disease because of its minimal trauma, mild postoperative pain, and rapid recovery. With the gradual promotion of this technology, surgical instruments and methods have also been greatly improved. At present, it has been developed from the 4-hole method 20 years ago to the 3-hole method, and even the 2-hole method and the single-hole method. At present, the most commonly used method in China is the 3-hole method. The size of the abdominal wall hole has also improved a lot, shortening the incision from about 1.6 cm long to 0.7 cm long. Therefore, the same laparoscopic cholecystectomy is also called minimally invasive surgery difference but very big. Patients seek a less painful and aesthetically pleasing surgery, while doctors seek medical perfection, and both doctors and patients want to reduce the number of incisions and the length of incisions. The most perfect surgery is the scarless abdominal wall surgery. Tian Mingguo, Department of Hepatobiliary Surgery, People’s Hospital of Ningxia Hui Autonomous Region A more practical clinical scarless (or hidden scar) cholecystectomy is transumbilical single-hole laparoscopic cholecystectomy, which has just started in China and abroad and has been carried out in our hospital. The surgical results are obvious (Figure 1 below). In comparison, the modified 2-hole approach laparoscopic cholecystectomy is more practical. This method only shows a 0.7 cm long scar in the upper abdomen, and the rest is almost not shown (Figure 2 below), but the operation time is significantly shorter than that of the single-port method. Figure 1 Transumbilical single-port method: the incision is all in the umbilical port. Figure 2 Improved 2-hole method: only a scar of about 0.7 cm in length is shown in the upper abdomen.
