I understand that patients often ask online what the success rate of surgery is (how certain it is) and what the risks are, but it is really difficult to answer these questions, and even if you do, it may not have much practical significance for the individual patient. First of all, the concept of “success rate” is ambiguous. If the surgery saves life, but there are different degrees of neurological deficits (such as hemiplegia, facial palsy, diplopia, choking on water, loss of vision, or even coma), is it successful or unsuccessful? Secondly, the so-called “success rate” is a statistical result of a group of cases, such as the total number of surgeries in a year, how much mortality, how much coma, how much hemiplegia, etc. It is a comprehensive statistical result of various cases, which is not significant for individual patients. If the doctor tells you that the “success rate” is 99%, if you are unfortunate enough to happen, then you may be the 1% (please understand that the analogy is not appropriate!!) Third, the so-called “success rate” has a lot to do with the location of the surgery, the age of the patient, the presence of underlying diseases, whether or not to operate again, etc., and cannot be generalized. For example, the mortality rate and neurological dysfunction rate of brainstem and nearby locations are higher than those of other locations; fourth, surgery is not a simple mechanical operation and repetition, the surgeon facing each case is concentrating his wisdom and physical strength in the battle with the disease, and his own experience and limits in the battle, even if a surgeon’s first 100 operations are successful, he cannot guarantee that the 101st case will be as successful as the previous 100 cases! Even if the first 100 operations are successful, there is no guarantee that the 101st case will be as successful as the first 100! Every surgery is a challenge, and the success of the previous surgery does not necessarily mean the same for the next one. It can be said that every surgeon’s life has surgery-related deaths and serious surgery-related complications, and we know how many families are involved in every surgery with a bad outcome, and often the families spend a lot of money! But medicine is a science, there are still many unanswered questions and unknowns, not every disease can be cured, and not every surgery can be exactly what you want! All we can do is to be wholehearted! Dedication to duty! Patients trust me, entrust me with their lives, this is a solemn trust, we can only use their knowledge and skills, do their best, do not consider their own honor and disgrace gain or loss, to operate wholeheartedly to diagnose and treat patients, for the best results, if we do our best, bad results still happen, I hope you can understand the doctor! Doctors and family members alike want the patient’s surgery to be successful! Fifth, if any doctor tells you that his surgical success rate is how much, I guess that is also he said casually, basically there is no scientific basis, as mentioned above, is the success rate of 99%, and who can guarantee that you are in that 99% within it? You will choose doctor A because his “success rate” is 99%, doctor B’s “success rate” is 95%, and doctor A? Therefore, it is not very meaningful to ask about the success rate, the key is to see whether the doctor is dedicated, dedicated, dedicated!
