The emergence of laparoscopic technology has greatly changed the way surgery is performed. Take gallbladder removal as an example, traditional gallbladder removal requires an incision of about 10 cm in the upper right abdomen, which takes at least 7 days to heal and leave a significant surgical scar in the abdomen after surgery, while laparoscopic gallbladder removal only requires a few (usually 4) 0.5-1.0 cm punctures in the abdomen to complete the surgery. The surgery is less invasive and can be discharged from the hospital in 2-3 days after surgery. Therefore, laparoscopic cholecystectomy has become the current gold standard method for the treatment of gallbladder stones. It has been 20 years since the emergence of laparoscopic technology, and the laparoscopic technique itself has been evolving. On the one hand, its application is becoming more and more extensive, and nowadays, the vast majority of diseases in abdominal surgery can be accomplished by laparoscopic techniques, such as gastric cancer, benign gastric tumors, small intestinal tumors, colorectal tumors, and pancreatic and splenic diseases. Especially for colorectal tumors, laparoscopic techniques are more widely used. On the other hand, laparoscopic techniques are developing toward fewer and more invisible incisions, such as single-port laparoscopic techniques. The single-port laparoscopic technique performs the surgery through a single puncture opening in the abdomen, and the location of the incision is usually chosen at the umbilicus, so that the postoperative scar will be hidden in the umbilical fossa and not easily detected, thus providing a significant cosmetic effect. Currently, single-port laparoscopic techniques have been used for cholecystectomy, liver cysts, ovarian cysts, appendectomy, and so on, with the more widely used being cholecystectomy. Single-port laparoscopic cholecystectomy reduces the four puncture ports scattered in the right upper abdomen and umbilicus in traditional laparoscopic cholecystectomy to one puncture port in the umbilicus, thus posing higher requirements for surgeons. Recently, the Second Department of General Surgery of Gansu Provincial People’s Hospital has successfully applied the single-port laparoscopic technique to cholecystectomy, appendectomy, and combined resection of liver cysts and ovarian cysts as well as the above organs, and achieved good clinical results.
