Has entered middle age, with the work and life of the old king of stability, do things are energetic, are given. However, recently Wang found himself eating a large amount of up, after eating not much will feel hungry again, not only feel full, and once hungry, you have to hurry to eat something. Otherwise, both hands shaking, sweating, and blackness in front of the eyes. In his words is constantly in front of the eyes of the gold stars ah. Gradually he had a countermeasure, as long as you feel hungry, you can always eat a piece of sugar, or drink a bowl of sugar water, you can feel much better. Slowly everyone knows that Wang is a willing eater of sugar, but also do not understand why he loves to eat sugar. However, the old king recently found himself with a new trouble. Not only did he find his weight getting heavier and heavier, but also in the early morning or in the morning he felt unbearably hungry; sometimes he slept too much to be woken up by others; or he could not control himself to shout and scream. Reactions are also slowly dulling, slow to speak, and emotionally unstable. People familiar with the old Wang is not a mental problem, are suggested that he went to the hospital to check. The doctor told Wang that he had a relatively rare disease, a pancreatic islet cell tumor. Simply put, there is a major problem with the command that regulates the stability of the body’s blood sugar, and surgery must be done quickly. After he went to the hepatobiliary and pancreatic surgery, he received a tumor removal surgery after the diagnosis and the location of the tumor were clear. After recovering his health after the surgery, Wang finally no longer needs to eat sugar, and no longer looks like he can’t eat enough, and his weight is gradually returning to normal, so he can work and live with peace of mind again. Insulinoma is a rare endocrine tumor of the pancreas. In layman’s terms, the patient mainly presents with frequent episodes of hypoglycemic symptoms; the symptoms can be relieved by supplementing sugar during the episodes; and the blood sugar is below the lower limit of normal level during the episodes. If the patient’s insulin level is tested, it is usually higher than normal. With the above symptoms, this condition should be highly suspected. The treatment of this condition mainly relies on surgery. The site and size of the tumor should be further defined and then a specific treatment plan should be developed and surgically removed. The key to treating this disease is to find the location of the tumor in the pancreas. We can usually perform ultrasound, CT, MRI (magnetic resonance imaging) and other imaging examinations, which can usually determine the location of the tumor. However, some tumors are also difficult to locate using the above methods. My personal experience is that DSA examination can be performed. Because the tumor is rich in blood supply, it can be visualized mostly. Ultrasound examination can be used to further determine the tumor site during surgery. After removal of the tumor, the diagnosis can be confirmed by intraoperative rapid pathological examination, and the patient’s blood glucose level should be monitored in time. If the blood sugar gradually increases, the tumor can be considered successfully removed. Otherwise, the remaining pancreatic tissue should be further explored to prevent missing multiple tumors.
