Perianal soft warts

Introduction A disease characterized by perianal soft palate or skin wrinkles, now known as infantal perianal pyramidal protrusions. The disease occurs in young children, usually women, and lesions occur in the anterior midline to the anus and can resolve over time. Generally no treatment is needed.

Cause

The symptoms associated with the conical bulge of the infant's perianal horn are due to the oral administration of the drug to the pregnant woman at the beginning of pregnancy, or congenital causes, leading to the embryo's primary anal developmental disorder. Rectal development is basically normal, with the blind end at the edge of the urethral bulbar muscle, or near the lower end of the vagina, and the puborectalis muscle surrounding the distal rectum. And often accompanied by dysplasia of the perineum, flat and so on.

Anal examination, rectal examination, anal reflex, anal examination

(1) digital rectal examination

Anal relaxation, contraction of the anal canal sphincter and anorectal ring contraction is not obvious and completely disappeared, if caused by injury, the anus can be scarred and scar tissue, incomplete incontinence can be diagnosed and the sphincter contractility is weakened.

(2) Endoscopy

Proctoscopy can observe the presence or absence of deformity in the anal canal, the mucosal state of the anal canal, and the closure of the anus. Fibrous colonoscopy can be used to observe the presence or absence of colitis, Crohn's disease, polyps, cancer and other diseases. The presence of complete rectal prolapse can be observed with a hard tube colonoscopy.

(3) Defecation angiography

The anatomical structure of the anal canal sphincter, anal canal and rectum can be measured. The X-ray barium examination of the dynamic functional state can observe the incontinence and its severity. Inadvertent leakage of a large amount of expectorant is a sign of incontinence.

(4) anal canal pressure measurement

The internal and external sphincters and the puborectal muscles can be measured for abnormalities. Anorectal inhibition of reflexes, to understand its basic pressure, systolic blood pressure and rectal expansion tolerance capacity. Incontinence patients with anal canal basis, reduced systolic blood pressure, internal sphincter reflex relaxation disappeared, and rectal sensation expansion tolerance capacity decreased.

(5) Electromyography measurement

The range of sphincter function can be determined to determine the degree of voluntary muscle involuntary muscle and its nerve damage and recovery.

Differential diagnosis

Identification: common perianal diseases in children have anal mucosal valgus, anal canal inflammation, red buttocks, perianal abscess, anal fistula and so on.

1. Congenital intestinal atresia: no meconium is discharged after birth, the anal area is covered with skin, and the anal area has a sense of impact when crying. Inverted position on the X-ray lateral slice, the end of the rectum is located on the shame line or slightly below it. Ultrasound and puncture method measured the blind end of the rectum to about 1.5cm from the skin of the anus.

2. The intestine is narrow.

3. Intestinal obstruction: No meconium is discharged after birth, and symptoms such as vomiting and abdominal distension are soon appearing. Local examination, the center of the perineum is flat, and the part of the anus is covered with skin. In some cases, there is a pigmentation with obvious depressions and radiation wrinkles, which stimulate the ring muscle contraction reaction. When the baby is crying or holding his breath, there is a protrusion in the center of the perineum. The finger can be placed in the area to have a sense of impact. The baby is placed in the low position of the hip and the lower part of the anus is diagnosed as a drum sound.
