How to check infant Hirschsprung's disease

Infants with Hirschsprung's disease require standardized medical examinations, including imaging studies, rectal biopsy, and stress testing, to confirm the diagnosis and evaluate the condition.

1. Imaging examination: understanding intestinal morphology and function

aPlain abdominal X-ray: By taking an abdominal X-ray, it is possible to detect whether there are signs of intestinal obstruction, intestinal dilatation, etc. This is an effective tool for preliminary screening.

b Barium enema: This is a classic diagnostic method. By injecting barium into the intestine and then performing an imaging examination, the location and range of megacolon can be clearly shown, and the narrowed area of ​​the intestine can also be observed.

2. Rectal mucosal biopsy: to determine whether there is ganglion cell loss

Rectal biopsy is the "gold standard" for diagnosing congenital megacolon. The doctor will take a small sample of rectal mucosa and observe whether there are ganglion cells under a microscope. If the ganglion cells are abnormally developed or missing, congenital megacolon can be diagnosed. This procedure is usually completed through the anus, which is less invasive and highly safe.

3. Rectal pressure test: assessing intestinal nerve function

Rectal pressure measurement Anorectal pressure reflex testing can help evaluate whether the anorectal nerve reflex is normal and assist in the diagnosis of megacolon nerve reflex disorder. This test is non-invasive and suitable for infants who cannot tolerate biopsy.

4Other auxiliary examinations: comprehensive assessment of health status

If necessary, routine blood tests, ultrasound and other examinations should be performed to assess the presence of complications such as secondary infection and intestinal perforation to ensure the safety and completeness of treatment.

If a baby has symptoms such as abdominal distension, constipation, and vomiting, you should be alert to the possibility of congenital megacolon. Seeking medical attention in time to make a clear diagnosis through the above examinations can avoid misdiagnosis. Only by obtaining medical help in time can we buy time for further treatment and ensure the healthy growth of the child.
