In the anorectal clinic, we often encounter some small patients, whose young age and poor expression and cooperation ability bring a lot of inconvenience to diagnosis and treatment. In fact, most infant and child anorectal diseases are easy to identify and simple and effective to treat as long as the characteristics are grasped, so you may want to learn about them if you are interested. 1. colorectal polyps: 2-5 years old children with blood in the stool, do not think that they have hemorrhoids. In fact, the most common cause of pediatric blood in the stool is colorectal polyps. This disease is simply understood as a small lump of flesh in the intestine, which ruptures and bleeds due to friction in the stool. It is usually shaped like a small grape with a tip, and if it is close to the anal opening, it can sometimes be brought out to the outside of the anus due to defecation. However, the vast majority of pediatric polyps, benign, with the development of colonoscopy technology, the use of minimally invasive removal under colonoscopy, painless, 2-3 days after surgery can be discharged, recurrence rate is very low. The most important thing is that you can find a lot of people who are not interested in the products and services of the company. If the abscess breaks down and the pus drips out, a tube leading to the anus will form at the mouth of the breach, which is an anal fistula. However, due to the simple body structure of children, the abscesses are superficial and the fistula canal is short and straight, so it is sufficient to find the source of infection in the anus and cut it open to drain it adequately during surgery. The surgery is simple, as long as you pay attention to local cleanliness and dryness, no special changes are needed, and the trauma will be completely healed in 10 days or so. 3. Prolapse: In some children with chronic constipation or diarrhea, a circle of bright red intestinal mucosa can be seen falling out of the anus when defecating, and then it goes back after defecating or with a gentle hand. This is called prolapse of the rectum. Parents will be particularly nervous when they see the intestines falling out. In fact, this disease with young children around the anorectal muscles gradually developed and perfect, muscle strength, to about 5 years old can be more self-healing. All parents have to do is to correct constipation and diarrhea, and send back in time when prolapse occurs.
