Understanding Hirschsprung’s Disease: Causes Symptoms and Treatment

Hirschsprung’s disease, also known as colonic aganglionosis, is a rare condition that affects the large intestine or bowel. In this article, we will explore the definition of Hirschsprung’s disease and its causes.

We will also discuss the symptoms that infants and older children may experience. By the end of this article, you will have a better understanding of this congenital condition.

Definition of Hirschsprung’s Disease

Hirschsprung’s disease is a congenital condition, meaning it is present at birth. It occurs when there are missing ganglion cells in the wall of the intestine.

Ganglion cells are responsible for coordinating muscle movement in the bowel. Without these cells, the affected portion of the bowel cannot relax.

This results in a blockage and prevents the movement of stool, leading to significant complications. Causes of Hirschsprung’s Disease

The exact cause of Hirschsprung’s disease is not yet fully understood.

However, researchers believe that it may be due to a combination of genetic and environmental factors. In some cases, Hirschsprung’s disease can run in families and may be inherited from a parent who also had the condition.

Other possible causes include improper migration of nerve cells during fetal development or a lack of blood flow to the intestine during pregnancy.

Symptoms in Infants

Infants with Hirschsprung’s disease may exhibit several symptoms that can help diagnose the condition. One of the earliest signs is difficulty with bowel movements.

Infants may fail to pass meconium, which is the dark, sticky stool that is typically expelled within the first 48 hours of life. Instead, they may have explosive stools, often accompanied by foul-smelling gas.

Other symptoms in infants include jaundice, poor feeding, poor weight gain, vomiting, and watery diarrhea.

Symptoms in Older Children

While the symptoms in older children can vary, the most common complaint is chronic constipation. This occurs when the affected portion of the bowel does not function properly, leading to fecal impaction.

Fecal impaction is a condition where the stool becomes stuck in the colon, making it difficult to have a bowel movement. Children with Hirschsprung’s disease may also experience malnutrition due to poor absorption of nutrients, which can result in slow growth and developmental delays.

In conclusion, Hirschsprung’s disease is a rare congenital condition characterized by missing ganglion cells in the bowel, leading to improper muscle movement and a blockage. Infants may experience difficulty with bowel movements, failure to pass meconium, explosive stools, jaundice, and poor weight gain.

Older children may suffer from chronic constipation, fecal impaction, malnutrition, and slow growth. While the exact cause of Hirschsprung’s disease is not fully understood, researchers believe it may be a combination of genetic and environmental factors.

If you suspect that your child may have Hirschsprung’s disease, it is important to seek medical attention for a proper diagnosis and treatment plan. Diagnosis of Hirschsprung’s Disease

Diagnosing Hirschsprung’s disease can be challenging as its symptoms can overlap with other digestive conditions.

However, healthcare professionals employ several methods to accurately diagnose this condition. Let’s explore the diagnostic process, including physical examinations and various tests.

Physical Examination

During a physical examination, doctors may look for certain indicators that suggest Hirschsprung’s disease. One feature is a swollen belly, which occurs due to the accumulation of stool in the blocked bowel.

Doctors may also feel for any loops of bowel in the abdomen, which can indicate the presence of a blockage. Additionally, a loss of muscle tone in the rectal muscles may be observed, which is another warning sign of Hirschsprung’s disease.

Diagnostic Tests

To confirm the suspicion of Hirschsprung’s disease, doctors may order a series of diagnostic tests. These tests provide valuable insight into the structure and function of the bowel.

Some common diagnostic tests include:

1. Abdominal X-ray: An abdominal X-ray can reveal signs of bowel obstruction, such as a distended colon filled with stool.

This image may help in identifying the affected area of the bowel. 2.

Barium Enema: In this test, a contrast material called barium is inserted into the rectum. The barium coats the walls of the intestine, allowing doctors to visualize any abnormalities on an X-ray.

The absence of barium in certain areas may suggest Hirschsprung’s disease. 3.

Anal Manometry: Anal manometry measures the pressure and muscle function in the rectum and anus. This test can help evaluate the rectal muscles’ ability to relax and contract, providing valuable information about the diagnosis of Hirschsprung’s disease.

4. Rectal Biopsy: A rectal biopsy is considered the gold standard for diagnosing Hirschsprung’s disease.

During this procedure, a small piece of rectal tissue is extracted and analyzed under a microscope. The absence of ganglion cells in the biopsy sample confirms the diagnosis of Hirschsprung’s disease.

Treatment of Hirschsprung’s Disease

Once diagnosed with Hirschsprung’s disease, prompt and appropriate treatment becomes crucial. The treatment plan typically involves a combination of pre-operative procedures, surgical intervention, and post-operative care.

Pre-operative Procedures

Before surgery, pre-operative procedures aim to alleviate symptoms and prepare the bowel for surgical intervention. One common pre-operative procedure is serial rectal irrigation.

This involves flushing the rectum with warm water to remove stool and relieve bowel distension. Serial rectal irrigation can help decompress the bowel and provide temporary relief before the surgical intervention.

Surgical Intervention

Surgery is the primary treatment for Hirschsprung’s disease. The goal of surgery is to remove the abnormal section of the colon and rectum and create a connection between the healthy colon and the anus.

The surgical approach for Hirschsprung’s disease can vary depending on the extent of the affected bowel and the age of the child. In more severe cases, the surgical procedure may require a staged approach.

This means that the surgery is done in multiple stages to allow the bowel to adjust gradually. In some cases, a temporary colostomy may be necessary.

A colostomy involves creating an opening in the abdominal wall to divert the stool into a bag, allowing the affected portion of the bowel to rest and heal. After a period of healing, a pull-through procedure is performed to bring the healthy colon down to the anus and close the colostomy.

This staged approach ensures the best possible outcome for the child.


Following surgery, children with Hirschsprung’s disease can experience a significant improvement in their symptoms. Chronic constipation and fecal incontinence, which are common in Hirschsprung’s disease, may gradually improve after surgery.

However, each child’s recovery process may vary, and it is essential to follow the healthcare professional’s instructions for post-operative care. Regular follow-up visits and monitoring are crucial to ensure better outcomes and address any potential complications.

In summary, diagnosing Hirschsprung’s disease involves physical examinations, such as observing a swollen belly and performing a rectal muscle assessment. Diagnostic tests, including abdominal X-rays, barium enemas, anal manometry, and rectal biopsies, help confirm the diagnosis.

The treatment for Hirschsprung’s disease typically involves pre-operative procedures to alleviate symptoms and prepare for surgery. Surgical intervention is then performed to remove the affected bowel segment and create a connection between the healthy colon and anus.

Recovery after surgery may lead to improvements in symptoms such as constipation and fecal incontinence. Close monitoring and follow-up care are vital for achieving the best possible outcomes in children with Hirschsprung’s disease.

In conclusion, Hirschsprung’s disease is a congenital condition characterized by missing ganglion cells in the bowel, resulting in a blockage and improper muscle movement. Infants may experience difficulty with bowel movements, while older children may suffer from chronic constipation and malnutrition.

Prompt and accurate diagnosis, through physical examinations and diagnostic tests, is crucial in determining the appropriate treatment. Surgical intervention, often done in stages, aims to remove the affected bowel segment and create a connection to the healthy colon and anus.

Post-operative care plays a vital role in the recovery process. Understanding Hirschsprung’s disease is essential for early detection, proper management, and improved outcomes in affected children.
