As for what you want them to do: internal medicine is to support medicine. Such as heart disease, hypertension and cerebral thrombosis. When the physician is sure to learn, he will not give it to surgery. Similarly, surgeons sometimes deal with some cases that even the family members of patients think are necessary for surgery, and surgeons can also carry out medical treatment through their own treatment methods. Especially those who think they need surgery because of some inflammation, they should be injected with anti-inflammatory drugs first, but sometimes the patients will get better wonderfully, and even they can judge that they have recovered well and don't need surgery, so they don't need surgery. This is the medical treatment in surgery. However, the patients who enter the operation are still the most.
Under normal circumstances, patients in surgery will not be handed over to internal medicine.
