The patient was male, 68 years old, with a history of diabetes for nearly 20 years, and his blood glucose control had been poor. Because a small wound appeared on his foot, causing redness and swelling of both toes, he was changed daily in the endocrine department of the hospital, and the wound was not treated with good results, and he was transferred to the burn unit, where he did not get better for about 3 weeks before and after, but continued to spread in all directions. Then we were transferred to the vascular surgery department of another hospital, and the doctor was also worried about the recurrence of stenting and the low success rate, saying that the limb would still be amputated in the end, meaning that it would be better to amputate the limb from the beginning. But the old man can still walk at the moment, and we really don’t know what to do. The above is the consultation of a real case, and I will mainly talk about the following issues in his case: I. The problem of the consultation department. This patient was initially seen by the endocrinology department, but was transferred to the burn department when the endocrinology department failed, and then to the vascular surgery department when the burn department failed. This is one of the reasons why I advocate the establishment of a multidisciplinary joint treatment center, patients do not know what department to go to when they are sick. Second, there was no treatment for local trauma. The patient did not debride the wound when he came to our hospital, which is one of the main reasons why the infection was not controlled. One of the first tasks is to do debridement of the infected necrotic inflammatory tissue, which can reduce the germ load and help control the infection, and also help provide conditions for the growth of new tissue. Therefore, it is necessary to clear the wound. Third, it is surprising that toe infections have to be amputated. In fact, this is very common in the field of general surgery or orthopedic treatment of diabetic foot, because there is no better way to control wound infection, only where the blood vessels are blocked to where the amputation is good! However, we still do not take into account the consequences of amputation, such as wound infection again after amputation faces another or even multiple surgeries, and the mortality rate is also very high. Fourth, the stent issue is also a point of controversy that we have been, the doctor did not inform the family of all the stakes before doing, I think this must be changed in the future treatment, must let the patient and family know as much as possible, so that they can participate in the development of treatment plans. Of course, each person’s situation is different and the problems encountered are diverse. Therefore, it is all the more important for us to set up special departments to treat them, so that patients cannot arrive at the hospital without knowing where to go, and that they cannot be treated more and more severely and end up having to have their limbs amputated. Of course, all these need us all to work together.
