Single-port laparoscopic surgery and conventional laparoscopic surgery are performed in the same way in the abdominal cavity. The only difference is that single-port laparoscopy has only one puncture hole in the abdominal wall of the abdominal cavity, and the main operations include the establishment of surgical access, microscopic exploration and microscopic operation. 1. Establishment of surgical access: The most commonly used surgical access for single-port laparoscopy is the transumbilical approach, in which the electronic endoscopic system enters the abdominal cavity through the umbilicus and observes the internal situation of the abdominal cavity through the electronic monitor. This approach has the advantage of beautiful incision compared with traditional laparoscopic surgery. 2. Scopic exploration: after the surgical operation system also enters the abdominal cavity through a single hole, it is necessary to further explore the abdominal cavity to observe the lesion location, scope, degree of lesion, etc., and know the next operation. 3. Microscopic operation: after finding the lesion, it is necessary to perform specific operations on the lesion, such as freeing the tissue, resection, hemostasis, suturing, etc. At present, single-port laparoscopic surgery is more and more widely used in the clinic, but it should be operated by specialized doctors.
