A single-port thoracoscopic procedure was started this year. Let’s summarize a little bit.　　We have mastered this more cutting-edge thoracoscopic surgical approach at present. This procedure has its drawbacks, but overall the right patient still gets the benefit, after all, the surgery is only done with a single hole in the anterior intercostal space, and no more holes are opened in the narrower posterior intercostal space. The postoperative pain of the patient is significantly reduced. The speed of recovery is accelerated. However, it is still not as safe as the traditional three-hole procedure when dealing with more complicated cases. Therefore, it is more important to choose the right patient and not to decide on a surgical approach in pursuit of a single orifice. Of course, many times the surgical plan can be modified during the procedure. The development of single-port can also contribute to the development of three-port lumpectomy techniques. After mastering the single-port procedure, it is obvious that the three-port procedure is more comfortable.
