Minimally invasive surgery is a surgical procedure in which the lesion is treated through a laparoscope. Minimally invasive surgery has smaller incisions and faster recovery, but it has certain limitations, including small field of vision, easy residue after surgery and high cost of surgery. 1. Small field of vision: minimally invasive surgery is performed by punching a hole and placing a cavity mirror to observe and treat the lesion, the field of vision is relatively small and it is difficult to deal with lesions with a large scope. 2. Postoperative residual: minimally invasive surgery may cause residual lesions that cannot be completely removed, which may lead to recurrence of the disease. 3. High cost of surgery: Most of the minimally invasive surgeries use disposable instruments, which will increase the cost of surgery. Overall, minimally invasive surgery has certain limitations, and the specific treatment process needs to be standardized under the guidance of clinicians.
