Patient: Dr. Li: Hello, I saw you on the website as a specialist in anorectal diseases! I want to ask you something, my baby was born with congenital low anal atresia disease, three days after the surgery, now that the surgery is done, is it necessary to do the dilation surgery? And how can I help my baby dilate? I heard that if you don’t dilate, it will grow back naturally, right? Can you give a tutorial or text steps to dilate the anus, because the place of surgery and the current residence is not in the same Cheng city, so back to the hospital no longer, want to self to dilate the anus, since I should be able to do it, right? I’d like to ask why there is congenital anal atresia? I don’t have any heredity and I didn’t take any drugs during pregnancy! I heard that it is caused by chromosomal errors? If the chromosomes are really caused by the surgery, then is it possible to grow up to be mentally retarded? I’m so worried, Dr. Lee, I hope you answer in detail! Thank you very much! Dongguan People’s Hospital Anorectal Department Li Xingqian: Hello pediatric anal atresia is a kind of anorectal malformation. The incidence is about one in 5,000, most occurring in the 4 – 8 weeks of gestation, any link during this period of abnormalities can form congenital anorectal malformations, this is a congenital disease, but there is no obvious relationship with genetics, do not worry. Your baby had the surgery earlier, which means that the treatment was timely and he should be able to defecate normally now, but he still needs the later treatment of anal dilation. Doctors should teach parents how to do this. Because this treatment is a chronic process, the child has to suffer more pain, and the parents should not stop because the child cries, otherwise the anal stenosis will have an impact on the child’s development later. There is no clinically formed anal dilator yet, we usually ask the family to prepare a sharp and smooth pen at one end instead, and return to the hospital every month to check and guide the next month’s treatment according to the anal condition, which usually takes more than six months. Good, wish your baby a speedy recovery! Patient: Thank you Dr. Li for your answer! For the treatment of post-surgical anal dilation, can you tell me more about how a process? How many days after the surgery can I start dilation? And you refer to the family to prepare a pointed and smooth pen instead, is it once a day for six months? How deep should I put the tip of the pen during each session? And is it a back and forth pumping or a stay there after inserting the time degree? Dr. Lee: I’ll wait for your detailed answer again! I want to dilate myself for a while first, and then go to your hospital halfway to help my baby review, because my baby has been operated for ten days now, I want to help my baby dilate in the near future? I need your help to answer! Thank you very much! Dongguan People’s Hospital Department of Anorectal Medicine Li Xingqian: Hello: You are welcome. I hope you have time to come to our hospital for a checkup. I was busy when I called yesterday, so my answer was not very clear. Anal dilation is a gradual process, and the dildo needs to stay for a few minutes after entering. It can be done once every two days. Li Xingqian Patient: Dr. Li, thank you for your sincere answer, your answer above about the dilation process really helped me a lot! I’m sorry to interrupt your busy schedule, but I’d like to ask you why my child’s stool is not like the one he used to have every day after the surgery. I need to extend my little finger after the second dilation to pull it out? I was worried that the anus had become narrower. I was worried that the anus had become narrower. But it’s only 11 days after the surgery, right? It can’t be narrowing, right? Sometimes there seems to be a tiny pus-like substance in the anus, but it’s just a little bit! I think it’s white, so I’m thinking too much about it and I think it’s inflammation of the rectum caused by finger dilation. The actual fact is that you will be able to get a lot more than just a few of these. The people’s hospital in Dongguan, the Department of anorectal Li Xingqian: Hello: I hope to take the time to come to the hospital to check, face to face communication will be more direct.
