The advantages of open surgery include clear vision, easy operation and thorough treatment; the disadvantages include large trauma, slow recovery and large scar. Advantages: Open surgery is the traditional open surgery, in which a knife is used to cut through the surface of the body layer by layer, exposing the area to be operated on. The field of vision exposed by this type of surgery is sufficient, and it is easy and convenient to operate, and the treatment such as excision is also more thorough. Disadvantages: Open surgery is more traumatic, with more intraoperative bleeding, slower wound healing, easier formation of scar after surgery, and slower recovery of normal feeding after surgery, which takes a longer time to heal compared with minimally invasive surgery. It is recommended to go to a regular hospital for consultation and obtain professional advice.
