The biggest advantages of laparoscopic surgery are minimally invasive, small incision, little interference to abdominal organs and little influence on immune function. After development, laparoscopic technique has been successfully extended from cholecystectomy to colorectal benign and malignant diseases, liver surgery and so on.
In addition to the characteristics of minimally invasive, laparoscopic surgery will not be "ineffective" because of "small incision". There is another advantage for the elderly, that is, the combined treatment of multiple diseases can be completed through puncture surgery, and the effect of treating multiple diseases at one operation can be achieved. Some patients with colon cancer complicated with cholecystolithiasis, hysteromyoma and other diseases can be treated at the same time through reasonable selection of puncture holes. Some multiple primary malignant tumors can also be removed together.
