The main difference between minimally invasive surgery for male circumcision and ordinary surgery is the use of a circumcision anastomosis. The anastomosis can remove the foreskin circumferentially in a short period of time, with a neat cut edge, less bleeding, less pain and shorter time, which is a good advantage compared to ordinary surgery. However, the anastomosis is not the best choice for patients with narrow circumcision or for those who are circumcised. Most of the circumcision procedures are done by traditional surgery to separate the narrowing of the foreskin and then circumcise the foreskin. However, the disadvantage of the anastomosis is that there is a possibility of postoperative bleeding, and when the patient is circumcised at one time, sometimes the mechanization of the cut does not allow for fine human trimming. Even if the cut edges are neatly trimmed, the overall appearance is not aesthetically pleasing, and traditional surgery cannot be completely replaced by the circumcision anastomosis.
