While relieving patients' pain,Single Port Laparoscopic as much as possible to reduce their iatrogenic trauma,Single Port Laparoscopic it has always been the main theme of medical development. Therefore,Single Port Laparoscopic the development direction of minimally invasive surgery technology should be: to make surgery more minimally invasive, to further improve the quality of life of patients,Single Port Laparoscopic and to achieve a perfect combination of minimally invasive and cosmetic.

NOTES came into being in this context. Its advantages are that it can reduce or hide surgical scars, reduce postoperative pain, promote postoperative recovery,Single Port Laparoscopic and realize a true scar-free surgery. Its appearance is minimally invasive surgery. Infused with new vitality,Single Port Laparoscopic it represents a new concept and leads the development direction of minimally invasive surgery.

In recent years, in order to reduce surgical trauma as much as possible,Single Port Laparoscopic laparoscopic cholecystectomy has developed from the classic four-hole technique to the current conventional three-hole technique and the few two-hole techniques, and now combined with umbilical laparoscopy and transvaginal abdominal cavity Mode of microscopic cholecystectomy.

Compared with single-hole laparoscopic cholecystectomy,Single Port Laparoscopic the scar of combined surgery is more concealed. Compared with NOTES through the gastrointestinal tract, the operation of combined surgical incision and suture is simple, there are fewer infections and other short-term and long-term complications,Single Port Laparoscopic and there is no risk of fistula. The distance from the vaginal entrance to the posterior fornix is short,Single Port Laparoscopic and it is quick and easy to enter the abdominal cavity. The wall is rich in elastic fibers, has strong ductility,Single Port Laparoscopic easy to expand, no pain, and can take out larger specimens.

The first umbilical and transanal laparoscopic sigmoidectomy performed first has achieved initial results. The combined operation method is to first insert an anastomotic device in the intestine and then to separate the intestinal tube,Single Port Laparoscopic thereby effectively avoiding the possibility of the intestinal content flowing into and contaminating the abdominal cavity,Single Port Laparoscopic and to a certain extent, reducing the complications of infection at the postoperative closure Incidence rate.

However, there are some problems with this combined technique. When the surgeon performs anastomosis,Single Port Laparoscopic it must be guided by an external magnet, which increases the difficulty and failure rate of the operation. This is the bottleneck of the current promotion of the operation.
