The 10-year-old boy Tian Tian found it difficult to concentrate in class because his attention was all on his stomach. Tian Tian told reporters that from time to time he would feel his stomach rise uncomfortably, and it was difficult to concentrate in class, and in gym class he could only sit on the sidelines and watch, and his beloved soccer could not kick. The mother of Tian Tian is very anxious, she said, her child has this situation for three months, thought it was eating bad stomach to eat medicine will be good, did not expect the pain one after another for such a long time, the results also fell very obvious. The cause of the abdominal pain was originally the appendix that was not cut off a year ago After a recommendation, Tiantian was brought to the hospital gastroenterology department by his mother, and the traces of abdominal pain were found after the consultation. After asking about the medical history, it was found that Tiantian had a history of acute appendicitis a year ago, but instead of surgical removal of the appendix, he was treated conservatively. After a fine catheterization, Tiantian found that the appendiceal cavity was unevenly thick and thin with segmental stenosis. Prof. Zhang used a balloon to expand the stenosis and then put in a plastic stent to continuously support and expand the stenosis. Tiantian finally got rid of the lower abdominal pain and his academic performance was restored. When it comes to a “capricious” appendix, should it be “cut” or “left”? Both Mr. Yang and Mr. Lu, who came to the follow-up clinic, were unable to be diagnosed in time for surgery due to the lack of obvious symptoms of appendicitis, and their conditions recurred after receiving conservative treatment. Professor Zhang Guoxin used endoscopic treatment to carefully insert a thin catheter into the appendiceal cavity to flush out the pus, and then put in a stent to drain the pus, which reduced the patient’s pain, gradually normalized his body temperature, and decreased his blood count. Now Mr. Yang and Mr. Lu are free from the trouble and restored to health. Usually, once a typical acute appendicitis is diagnosed, within 72 hours of the onset of the disease, doctors usually recommend the patient to have the appendix removed for the purpose of radical treatment. If the appendix is swollen beyond 72 hours, the risk of surgery is significantly higher and clinical norms do not allow surgeons to risk surgery again. Of course, a perforated appendix is a different story, and that requires immediate surgery. However, there are often a variety of atypical acute appendicitis in clinical practice, which may not be easily diagnosed in the early stage, and by the time the diagnosis is clear, it is no longer suitable for surgery; or the patient himself may be hesitant to operate, and by the time he makes up his mind, the time for surgery is lost. At this time, doctors mostly recommend conservative treatment and consider surgery when the next acute attack occurs, so patients have the worry of not knowing when and where they will get the disease again. At present, the gastroenterology team has completed more than 20 cases of appendiceal imaging, irrigation and treatment, all of which have achieved good results. This new method of endoscopic treatment of acute and chronic appendicitis provides rapid relief for patients who have missed the timing of surgery for acute appendicitis, new diagnostic and treatment ideas for chronic appendicitis that cannot be clearly identified, and a new way to identify appendicitis for unexplained right lower abdominal pain. The pain of acute appendicitis is initially located in the upper abdomen or around the umbilicus. Many people cannot distinguish between appendicitis and gastroenteritis. The pain of acute appendicitis is initially located in the upper abdomen or around the umbilicus, resembling stomach pain and may be accompanied by mild nausea. This is the earliest manifestation of acute appendicitis and is easily misdiagnosed as acute gastroenteritis or gastric disease. Because this early epigastric or periumbilical pain is pain that is transmitted through visceral nerves, patients often cannot pinpoint the site of pain. After several hours or more of epigastric or periumbilical pain, the pain shifts and becomes fixed in the right lower abdomen. The pain is persistent and gradually worsens, or it may worsen paroxysmally on top of the persistent pain, and most of the pain is relatively mild and tolerable. Acute appendicitis usually has a normal temperature at the onset of the disease, and after a period of time, low or moderate fever may appear, while high fever is less common. The patient has pressure pain and rebound pain in the right lower abdomen. Generally speaking, the degree of rebound pain in the right lower abdomen directly reflects the degree of the disease, if the rebound pain is mild, the disease is also mild, on the contrary, the disease may be more severe, or even perforated. The above symptoms should be promptly sent to the doctor for treatment. Once the diagnosis of acute appendicitis is clear, we generally strive to remove the appendix as soon as possible in order to cure it.
