I. What is anorectal disease? Anorectal diseases are common and frequent diseases that are unique to human beings. The incidence rate is high, in a broad sense: all kinds of diseases occurring in the anus and large intestine are called anorectal diseases, there are more than 180 kinds. In a narrow sense: various diseases occurring on the anus and rectum, there are more than 30 common ones, such as: internal hemorrhoid, external hemorrhoid, mixed hemorrhoid, anal fissure, anal fistula, perianal abscess, anal skin disease, anal sinusitis, proctitis, rectal ulcer, export constipation, rectal prolapse, rectal prolapse, rectal prolapse, rectal stenosis, anal incontinence, anal canal cancer, rectal cancer, anal papilloma, rectal polyp, anorectal tuberculosis The following are some of the most common types of anorectal cancer: anorectal nerve disease, acromegaly, anorectal congenital malformation, anorectal trauma, etc. According to the authoritative data of the Chinese Anal and Intestinal Association, the incidence of anal and intestinal diseases is 59.1%, of which the incidence of hemorrhoids is the highest, accounting for 87.25% of the total number of cases. More importantly, many people do not know enough about the dangers of anorectal diseases, and often think it does not matter; or purchase some drugs to relieve symptoms when the disease strikes. In fact, if anorectal diseases are not treated scientifically and effectively, constipation, blood in the stool and prolapse in the light cases; swelling and pain in the heavy cases, rupture of blood vessels and inability to defecate, bringing great inconvenience to the lives of patients and families. Second, the cause of the high incidence of anorectal disease? 1, bad defecation habits: squatting position to read a book and newspaper when going to the toilet, resulting in squatting and prolonged defecation time, easy to cause stasis of blood in the anorectum and induce disease. Smoking when going to the toilet can buffer the brain’s defecation reflex, which is very easy to cause constipation. Excessive force during defecation, some people do not care whether the feeling of defecation is strong, blindly and constantly violently struggle, can only make the rectum anus and pelvic floor muscles increase unnecessary burden and local stasis, leading to the occurrence and development of disease. 2, defecation abnormalities: diarrhea and constipation are important factors in the pathogenesis of anal diseases. Constipation is the biggest bane, long-term retention of toxic substances in the rectum can not only induce rectal cancer, and the accumulation of feces, affecting blood circulation. The effort to solve the dry fecal mass will certainly put the anus under greater pressure, producing a series of pathological changes such as stasis, swelling and fissures. Diarrhea is often a clinical manifestation of colon disease, diarrhea can also increase the chances of local anal infection, producing anal sinusitis, inflammatory external hemorrhoids, perianal abscesses and other diseases. 3, dietary factors: in daily life, it is natural that dietary patterns or dietary varieties inevitably change. Such as the quality of food coarse and fine, the change in the type of vegetables and the amount of increase or decrease, the amount of protein, fat, starch, fiber and other content, water intake, can directly affect the fecal composition, causing anorectal disease. The incidence of anorectal diseases has increased significantly due to the fact that alcohol and spicy food can stimulate the mucous membrane of the digestive tract, causing vasodilation and colon dysfunction. National census data show that the incidence of spicy food is 61.6%, and the incidence of those who like to drink alcohol is 64.6%, both significantly higher than the total incidence. 4, occupational factors: long-term standing or sedentary. Because of the upright or sedentary posture, the anorectum resides in the lower part of the body, and the hemorrhoid veins do not reflux well. 5, chronic diseases: such as long-term malnutrition, physical weakness, causing anal sphincter relaxation and weakness. Long-term chronic bronchitis, emphysema, coughing and wheezing caused by the rise in abdominal pressure, pelvic stasis. Chronic hepatitis, hepatic steatosis, diarrhea, colitis, etc. are all triggers for the occurrence of anal diseases. Therefore, in prevention, we should pay attention to the patient’s systemic status and take reasonable and effective preventive measures.
