Ms. Zhang, a 30-year-old secondary school teacher, has been working under more pressure since she became a classroom teacher. Some time ago, blood suddenly appeared in the stool, but the amount is not a lot, Ms. Zhang did not take it seriously. But one morning after the bowel movement, the anal opening suddenly came out of a piece of things, and constantly spraying blood, which can be Zhang teacher scared, in fact, she is bleeding hemorrhoids, there is no big problem, after treatment can be completely back to normal. However, Ms. Zhang was still very nervous and asked: Isn’t hemorrhoid a minor disease? How can it bleed so much? Will the operation be painful? Will it recur in the future? What should I pay attention to in the future? Hemorrhoids are one of the most common diseases in anorectal surgery, and there is often a saying that “ten people have nine hemorrhoids”. According to the different parts of the disease, hemorrhoids can be divided into internal hemorrhoids, external hemorrhoids and mixed hemorrhoids. The main clinical manifestations of hemorrhoids are blood and prolapse, which can be complicated by thrombosis, incarceration, strangulation and defecation difficulties. According to the symptoms of internal hemorrhoids, according to its severity can be divided into 4 degrees. i degree: blood, dripping blood, bleeding can be stopped by itself, no hemorrhoids prolapse. ii degree: often have blood in the stool, hemorrhoids prolapse during defecation, can be self-contained after defecation. iii degree: may have blood in the stool, defecation or standing for a long time, and coughing, exertion, weight-bearing hemorrhoids, need to use the hand to return the hemorrhoids. iv degree: may have blood in the stool, the hemorrhoids continue to prolapse, or easy to come out of the hemorrhoids after the return. i, ii degree can generally be treated with medication, and can also be used for treatment. ii degree: can be used for treatment of the hemorrhoids. The symptoms of I and II degrees can be improved by medication, while III and IV degrees need surgery. There are many surgical methods for treating hemorrhoids, and it is important to make a personalized choice based on the patient’s specific situation. Traditional surgery, such as external peeling and internal ligation, is the most classic surgical method of hemorrhoidal surgery, but due to the disadvantages of large surgical trauma, slow recovery, and many complications, it has gradually been replaced by minimally invasive techniques. Nowadays, minimally invasive techniques in hemorrhoid surgery include PPH and TST. PPH is suitable for III and IV degree internal hemorrhoids with cyclic prolapse and II degree internal hemorrhoids with repeated bleeding, while TST is especially suitable for internal hemorrhoids with point prolapse, which can maximally preserve normal anal canal tissues, and for patients with severe prolapse of internal hemorrhoids or combined with prolapse of rectal mucosa, the large-diameter anastomosis with a diameter of 36mm is still able to achieve minimally invasive treatment results. The treatment effect of the 36mm large diameter anastomosis can still be minimally invasive. The first step in preventing hemorrhoids is to prevent prolonged sitting and standing. For teachers who need to stand for a long time, surgeons, police and long-term sedentary bank employees, office workers, white-collar workers, etc., should pay attention to regular changes in position, in the work gap to strengthen the whole body and local muscle movement, especially the anal contraction exercise. The key to preventing hemorrhoids is “how to use the anus”. Should develop good defecation habits, to achieve regular defecation, to maintain smooth, to eliminate defecation when reading newspapers, play cell phones and other bad habits. Secondly, if there is constipation and diarrhea, it should be treated in time. Long-term constipation or diarrhea patients, due to prolonged defecation time or increased frequency of defecation, can make the abdominal pressure increases, anorectal congestion and varicose veins, anal sphincter relaxation, easy to form hemorrhoids. So timely prevention and treatment of constipation, diarrhea is very important. Finally, pay attention to anal hygiene. Adopt the habit of washing the anus and warm water bath before going to bed, promote anorectal blood circulation, can reduce the possibility of hemorrhoids. Therefore, as long as usually pay attention to a little, there will be no after the “stock” worry.
