Hirschsprung’s disease, also known as congenital aganglionic megacolon, is a rare condition that affects the large intestine (colon) and causes chronic constipation. The disease is caused by the absence of nerve cells in the lower part of the colon, which
results in a lack of peristalsis (the coordinated contractions that move stool through the colon). In this blog, we will discuss in detail the types, symptoms, causes, risk factors, prevention, diagnosis, stages, treatment and management, road to recovery and aftercare, and frequently asked questions about Hirschsprung’s disease.
There are two types of Hirschsprung’s disease: congenital and acquired. Congenital Hirschsprung’s disease is present at birth and is caused by genetic mutations. Acquired
Hirschsprung’s disease, on the other hand, develops later in life and is caused by other factors such as infections or other medical conditions.
Another way to classify Hirschsprung’s disease is based on the length of the colon affected. Short-segment Hirschsprung’s disease affects only the rectum and a short segment of the colon, while long-segment Hirschsprung’s disease affects a longer segment of the colon. Total colonic aganglionosis is the most severe form of the disease, affecting the entire colon.
The symptoms of Hirschsprung’s disease can vary depending on the severity and extent of the condition. Some infants may show symptoms from birth, while others may develop symptoms later in infancy or childhood. Here are some of the most common symptoms of Hirschsprung’s disease:
1. Chronic constipation: This is the most common symptom of Hirschsprung’s disease. Infants with the condition may have difficulty passing stool, or may not pass stool for several days at a time.
2. Abdominal distension: Infants with Hirschsprung’s disease may have a swollen or distended abdomen due to the build-up of stool and gas in the colon.
3. Failure to thrive: Infants with Hirschsprung’s disease may have difficulty gaining weight and growing properly due to the chronic constipation and digestive issues.
4. Vomiting: In severe cases, infants with Hirschsprung’s disease may experience vomiting, which can be a sign of a blockage in the intestine.
5. Diarrhoea: In some cases, infants with Hirschsprung’s disease may have episodes of diarrhoea, which can be a sign of a partial blockage in the intestine.
6. Intestinal obstruction: In severe cases, infants with Hirschsprung’s disease may develop an intestinal obstruction, which can cause severe abdominal pain, distension, and vomiting.
7. Rectal bleeding: In rare cases, infants with Hirschsprung’s disease may experience rectal bleeding, which can be a sign of a serious complication.
If your child is experiencing any of these symptoms, it is important to speak with a paediatric gastroenterologist for a proper diagnosis and treatment plan. Early detection and treatment of Hirschsprung’s disease can prevent serious complications and improve outcomes for affected children.
It occurs due to the absence of nerve cells in a portion of the large intestine. The exact cause of this absence of nerve cells is not known, but there are some theories regarding the cause of Hirschsprung's disease.
1. Genetic factors: Hirschsprung's disease is known to run in families, suggesting that there may be a genetic component to the condition.
2. Environmental factors: Some studies have suggested that environmental factors, such as exposure to certain chemicals or toxins, may play a role in the development of Hirschsprung's disease.
3. Abnormalities during foetal development: This could include problems with the migration of nerve cells to the intestine during development.
4. Other medical conditions: Some medical conditions, such as Down syndrome, can increase the risk of developing Hirschsprung's disease. While the exact cause of Hirschsprung's disease is not fully understood, it is likely that a combination of genetic and environmental factors. Early detection and treatment can prevent serious complications and improve outcomes for affected children.
Hirschsprung's disease is a rare condition that affects approximately 1 in 5,000 births.
While the disease's exact cause is unknown, several risk factors have been identified.
They are:
1. Family history: Hirschsprung"s disease is known to run in families, suggesting that there is a genetic component to the condition. Children who have a sibling or parent with Hirschsprung's disease have a higher risk of developing the disease.
2. Gender: Boys are four times more likely to be affected by the disease than girls.
3. Down syndrome: Children with Down syndrome are at an increased risk of developing Hirschsprung's disease.
4. Other genetic conditions: Hirschsprung's disease has been associated with several other genetic conditions, including Waardenburg syndrome, Mowat-Wilson syndrome, and neurofibromatosis.
5. Prematurity: Premature infants are at an increased risk of developing Hirschsprung's disease. This may be related to the incomplete nervous system development in premature infants.
6. Maternal smoking: Maternal smoking during pregnancy has been associated with an increased risk of Hirschsprung's disease.
There is no known way to prevent Hirschsprung’s disease, as it is a congenital condition that is caused by genetic mutations. However, early detection and treatment can help prevent serious complications and improve outcomes for children with the disease.
Diagnosing Hirschsprung’s disease can be challenging, as the symptoms can be similar
to other gastrointestinal conditions. The following tests may be used to diagnose the
disease:
1. Barium enema: This test involves injecting a contrast dye into the colon and taking X-rays to look for abnormalities.
2. Anorectal manometry: This test measures the pressure in the rectum and anus and can help determine if there is a lack of nerve cells in the area.
3. Biopsy: A small tissue sample is taken from the colon and examined under a microscope to look for the absence of nerve cells.
Hirschsprung’s disease is typically classified into three stages:
Stage 1: The new-born period, during which symptoms such as failure to pass
meconium and abdominal distension may occur.
Stage 2: The transition period, which occurs around 2-3 weeks of age, during which symptoms such as chronic constipation and poor feeding may become more pronounced.
Stage 3: The established disease period, during which Hirschsprung disease symptoms such as enterocolitis and bowel obstruction may occur.
Hirschsprung disease treatment involves surgery to remove the portion of the colon that
is affected by the absence of nerve cells and create a new connection between the healthy portion of the intestine and the anus, allowing for normal bowel function. The specific type of surgery will depend on the extent and severity of the disease.
1. Pull-through surgery: This is the most common surgical procedure for Hirschsprung's disease. During a pull-through surgery, the affected portion of the colon is removed, and the healthy portion of the colon is pulled through to the anus.
2. Colostomy: In some cases, a colostomy may be necessary if the disease is severe or if the child is not healthy enough to undergo a pull-through surgery. Stool passes through the stoma and is collected in a bag outside the body.
Following surgery, the child may need to stay in the hospital for several days to monitor for any complications. Pain medication and other supportive care may be necessary during this time. Once the child is discharged from the hospital, they will need ongoing care and management to ensure the new connection between the healthy portion of the
colon and the anus is functioning properly.
1. Diet modifications: Children with Hirschsprung's disease may need to follow a special diet to ensure adequate nutrition and promote healthy bowel function. This may include avoiding certain foods that can cause constipation or diarrhoea and increasing fibre and water intake.
2. Medications: Certain medications, such as laxatives or stool softeners, may be necessary to promote regular bowel movements and prevent constipation.
Follow-up appointments: Children who have undergone surgery for Hirschsprung's disease will need regular follow-up appointments with a healthcare provider to monitor their progress.
While surgery is the primary treatment for Hirschsprung's disease, ongoing care and
management are important for long-term success. With proper treatment and management, most children with Hirschsprung's disease can live healthy and normal lives.
The road to recovery for a child with Hirschsprung’s disease can be challenging, as the
child may need to undergo surgery and may experience complications such as enterocolitis. After surgery, it is important for the child to get plenty of rest and follow a diet that is high in fibre and fluids to promote healthy bowel function.
Regular follow-up visits with a paediatric gastroenterologist are also important to monitor the child’s growth and development and to detect any complications.
Is Hirschsprung’s disease a genetic condition?
Yes, Hirschsprung’s disease is caused by genetic mutations that affect the migration of neural crest cells during foetal development.
Can Hirschsprung’s disease be prevented?
There is no known way to prevent Hirschsprung’s disease, as it is a congenital condition.
What are the Hirschsprung disease symptoms?
The most common Hirschsprung disease symptoms include chronic constipation, failure to pass meconium in the first 48 hours of life, abdominal distension, and pain, vomiting, delayed growth and development.
How is Hirschsprung’s disease diagnosed?
Hirschsprung’s disease can be diagnosed using tests such as barium enema, anorectal manometry, and biopsy.
What is the treatment for Hirschsprung’s disease?
The main treatment for Hirschsprung’s disease is surgery to remove the affected portion of the colon and reattach the healthy portions.
What are the possible complications of Hirschsprung’s disease?
Complications of Hirschsprung’s disease may include enterocolitis, bowel obstruction, and poor growth.
Can Hirschsprung’s disease be cured?
Surgery to remove the affected portion of the colon can effectively cure Hirschsprung’s disease, but regular follow-up visits and ongoing management are still necessary.
Can a child with Hirschsprung’s disease lead a normal life?
With appropriate treatment and management, most children with Hirschsprung’s disease can lead normal, healthy lives.
What should I expect during my child’s recovery from Hirschsprung’s disease
surgery?
After surgery, your child may need to stay in the hospital for a few days to recover. They may need to have a temporary colostomy, which will be removed later. Your child may experience pain and discomfort and may need to follow a special diet for a period.
Can Hirschsprung’s disease be diagnosed in adults?
While Hirschsprung’s disease is typically diagnosed in infancy or childhood, it is possible for adults to develop the condition. Adult-onset Hirschsprung’s disease is rare and may be mistaken for other gastrointestinal conditions.
