Hirschsprung’s disease: Treatment, symptoms, advice and help
About Hirschsprung’s disease
Hirschsprung’s disease is a congenital disease involving the muscles of large intestines. It results from absence of nerve cells in a segment of large intestines which leads to impaired muscular contraction of intestinal muscles. It is usually diagnosed in first few weeks after birth. It is not a curable disease but it can be treated with appropriate surgical correction.
Hirschsprung’s disease: Incidence, age and sex
Hirschsprung’s disease is not a very common occurrence in the general population. It is present since birth and has about four times higher predilection for males as compared to females.
Signs and symptoms of Hirschsprung’s disease: Diagnosis
The clinical features of Hirschsprung’s disease are evident within a few weeks after birth, in most of the cases. Inability to pass meconium (first stool) within 24 hours of birth is usually the first sign of this disease. Milder form of disease may be difficult to detect during early infancy. However, other features like distended abdomen, vomiting, diarrhoea and poor weight gain may appear later and lead to suspicion of Hirschsprung’s disease.
Loops of swollen bowel may be detected on palpation during a clinical evaluation. Sigmoid colon or rectum is usually affected. The diagnosis can be established by rectal biopsy wherein small tissue sample is taken and studied microscopically. Absence of nerve ganglion cells in the tissue sample confirms the diagnosis of Hirschsprung’s disease. Other investigations like rectal manometry or barium enema may be considered, if needed.
Causes and prevention of Hirschsprung’s disease
Hirschsprung’s disease results from the absence of nerve cells in the muscles of the large intestine especially the sigmoid colon and rectum. The exact cause of absence of these nerve cells is not clear. In normal individuals, the food in the intestines moves forward by rhythmic contractions of the intestinal muscles. These contractions are termed as peristalsis. However in Hirschsprung’s disease, a particular segment of the large intestine does not have nerve cells to stimulate and coordinate muscle contractions. Absence of such muscle contractions leads to accumulation of food matter in the affected segment.
Hirschsprung’s disease: Complications
There are high chances of rupture or even infection of the affected intestinal segment. Longstanding cases may result in malnutrition and poor weight gain.
Hirschsprung’s disease: Treatment
Hirschsprung’s disease is incurable but it can be surgically managed. Surgery includes resection of the involved segment followed by re-suturing of colon with anal canal. Most of the affected individuals show improvement after surgery. Sometimes persistent diarrhoea may be complained of, post surgery. Alternatively, another procedure known as rectal irrigation may be considered wherein the affected bowel segment is decompressed to relieve high pressure.
