Generally speaking, as long as it is a clinical surgery, there is a certain degree of risk. However, the degree of risk is different for different parts of the body and different types of surgeries, so minimally invasive surgeries for the elderly have a certain degree of risk. Due to a variety of reasons such as anesthesia before surgery, complexity of the patient’s condition during surgery and so on, any surgery is dangerous to a certain extent and may cause irreversible damage to the patient. Minimally invasive surgery is a popular surgical procedure, i.e., the surgery is done through a smaller incision, and the entire surgery is relatively less damaging to the patient, but it still carries a certain amount of risk and danger. Different parts of the surgery and different surgical methods have different levels of risk. Before the surgery, the doctor will recommend a suitable surgical method for the patient to minimize the risk of the surgery, and before the surgery, the patient will be asked to sign a surgical risk notification letter to inform the patient of the risk of the surgery in advance, so that the patient can carefully make a choice based on his/her own situation.
