Anal membrane atresia

　　Anal membrane atresia is a low-lying malformation and a common type, caused by developmental disorders in the late embryonic period, abnormal absorption of the anal membrane between the primitive anus and the distal end of the rectum. Sometimes, it can be accompanied by subcutaneous potential fistulae that extend to the anterior anal area, with the development of the anal canal and rectum being basically normal, and generally not accompanied by other malformations.

　　In addition to general symptoms, anal membrane atresia can also cause other diseases. The diseases that can be complicated with this disease are common, including intestinal obstruction and intestinal inflammation. Therefore, once found, active treatment is needed, and preventive measures should also be taken in daily life.

　　After birth, there is no meconium excretion, crying unrest, vomiting, and abdominal distension. There is a明显 indentation at the normal anal position, and the anal canal is covered by a layer of septum. The septum is sometimes very thin, and it can be seen through it to see the deep blue meconium retained in the anal canal and rectum. When the child cries and screams, the septum bulges outwards obviously, and there is a significant impact when the fingers touch it. Stimulation of the perianal area can cause muscle contraction of the anal sphincter.

　　Anal membrane atresia has a明显凹陷 at the normal anal position, and the anal canal is covered by a membrane. The membrane is sometimes very thin and can allow the deep blue meconium to be seen in the anal canal and rectum. This disease is a congenital malformation, with no effective preventive measures. Early treatment should be given after diagnosis to avoid serious complications.

　　The following examinations need to be done for patients with anal membrane atresia:

　　First, puncture examination.

　　Second, rectal examination:Rectal examination is a simple, convenient, and very important clinical examination method in which the doctor inserts a finger into the patient's anus. Rectal examination does not require any auxiliary equipment.

　　Anal membrane atresia is a congenital malformation. Infants do not have meconium excretion after birth, so there are no dietary taboos. The patient's diet should be light, easy to digest, eat more fruits and vegetables, and have a reasonable diet. In addition, patients should avoid spicy, greasy, and cold foods.

　　Anal membrane atresia is a common anorectal disease. If it is found, it should be treated promptly, otherwise it will have a great impact on the patient's life. Because the position of anal membrane atresia is low, the surgical operation is easy, and once diagnosed, anal membrane incision or resection can be performed.

　　1. Anal Membrane Resection:Cut the anal membrane, suck out the meconium, cut off the anal membrane along the anal margin, dilate the anal canal so that the index finger can pass through, slightly mobilize the mucosa at the lower end of the rectum, and then suture the rectal mucosa loosely to the perianal skin. Begin anal dilation 10 days after surgery, 2-3 times a week, until the anus is free of stenosis and defecation is smooth.

　　2. Anal Membrane Incision:Take a transverse incision from the anterior and posterior longitudinal incisions at the perineal anal凹陷 area, cross-cut the anal membrane, make the anal opening and outer opening communicate, and then dilate the anus to the point where the index finger can be inserted. Early dilation of the anus is required after surgery, until defecation is normal. However, many people believe that simply cutting the anal membrane has poor long-term effects, often resulting in anal stenosis and requiring further surgical treatment, so this method is rarely used.
