Anal ectopic

Anal ectopic introduction The anus is the end of the anorectal and is also an organ of the human body. It is located between the buttocks. In traditional Chinese medicine, the anus is also called "the door", which is made by the five internal organs. "Making" has the meaning of an envoy in ancient times, that is, the lesions of the five internal organs can be reflected to the anus. Anal ectopic means that the anus is not in the normal position, located near the ankle or scrotum, but the bowel movement is smooth. basic knowledge The proportion of illness: 0.005%-0.008% Susceptible people: no specific population Mode of infection: non-infectious Complications: urinary infection

Anal ectopic cause

The disease is a congenital malformation and the cause is unknown.

Anal ectopic prevention

Diet: No special restrictions, a diet with a lot of spices can cause a burning sensation in the skin. Light diarrhea with low slag digestible diet, severe diarrhea for intestinal bactericidal drugs or compound camphor sputum treatment. Constipation should eat more food to increase the amount of feces and drink more water, take liquid paraffin or Ma Renzi spleen pills to make the stool soft and smooth.

Skin protection: It is very important to protect the skin. Moisture and exudation can cause leakage of feces and fecal odor. The skin is then coated with a skin protectant to prevent intestinal contents from coming into contact with the skin and avoid irritation.

Anal ectopic complications Complications, urinary infections

It is easy to complicated the infection of organs such as the scrotum near the anus.

Anal ectopic symptoms common symptoms anal or anal canal narrow anal sphincter relaxation

Visual anus is not in the normal position, located near the ankle or scrotum, but generally no defecation disorder, and some with small anus or anus without sphincter.

1. X-ray findings of the abdominal position flat film showed low colonic obstruction. In the photos of the lateral and anterior and posterior positions of the barium enema, the typical sacral segment and the dilated bowel segment can be seen. The function of sputum excretion is poor. After 24 hours, there are still sputum retention. If the sputum is not washed out in time, vermiculite can be formed. In the case of enteritis, the intestinal wall of the dilated bowel is serrated, and the expansion of the intestine in the neonatal period is more than half a month after birth. If you still cannot be diagnosed, do the following.

2, biopsy taken from the anus more than 4cm above the rectal wall of the rectal wall and a small layer of muscle layer, check the number of ganglion cells, the lack of ganglion cells in children with megacolon.

2, anorectal manometry to determine the reflex pressure changes of the rectum and anal sphincter, can diagnose the congenital megacolon and identify constipation caused by other causes. In normal children and functional constipation, when the rectum is stimulated by swelling, the internal sphincter immediately undergoes reflex relaxation and the pressure drops. The internal sphincter of the congenital megacolon not only does not relax, but also causes obvious contraction and increases the pressure. This method can sometimes produce false positive results in newborns within 10 days.

3, biopsy taken from the anus more than 4cm above the rectal wall of the rectal wall and a small piece of muscle layer, check the number of ganglion cells, megacolon children lack of ganglion cells.

4, rectal mucosal histochemical examination method is based on the submucosal and myometrial ganglion cells lacking hyperplasia, hypertrophic parasympathetic preganglionic fibers continue to release a large amount of acetylcholine and choline enzyme, chemically determined Both the number and activity are 5-6 times higher than normal children, which is helpful for the diagnosis of Hirschsprung's disease and can be used for newborns.

Anal ectopic diagnosis

diagnosis

Diagnosis can be based on medical history, clinical symptoms, and laboratory tests.

Differential diagnosis

High malformation

1, high malformation

(1) Anorectal hypoplasia: 1 rectal prostatic urethra fistula: fistula opening in the posterior urethra, no anal internal sphincter, external sphincter is not obvious, blind end is located on the PC line.

2 innocent: there may be a fiber-optic band connection between the blind end and the urethra, no anal internal sphincter, only external sphincter marks, blind end flat or higher than PC line.

(2) rectal atresia: the rectal blind end stops at different heights, the anus and anal canal are normal, there are anal internal and external sphincter and levator ani muscle, and maintain normal relationship with the anal canal.

2, the middle position deformity

(1) rectal urethral bulbar fistula: the rectal blind end of the rectum is located above the corpus cavernosum muscle, the puborectalis muscle surrounds the rectum blind end fistula, the anal internal sphincter is absent, and the rectal blind end is located between the PC line and the I line. .

(2) anal hypoplasia, innocent: the rectal blind end of the urethral bulb above the cavernosal muscle, the puborectalis muscle surrounds the rectal blind end. The anal internal sphincter is absent, the external sphincter only shows traces, and the rectal blind end is located between the PC line and the I line.

3, low malformation

(1) Anal skin spasm: The fistula is open to the anus to any part of the midline of the back of the urethra, and the scrotum is mostly. The anal canal is lobed and the fistula is covered by a thin skin flap. The puborectal muscle is normal.

(2) Anal stenosis: the anus and internal and external sphincters are normal.
