Chronic Intestinal Pseudo-Obstruction
What is chronic intestinal pseudo-obstruction (CIPO)?
CIPO is a rare and serious condition that affects the movement of the digestive tract, including areas from the esophagus to the rectum and sometimes the bladder. This disorder causes the muscle contractions that normally move food through the intestines to become weak and uncoordinated, mimicking the symptoms of a physical blockage, though none is present.
Causes of chronic intestinal pseudo-obstruction
CIPO can result from muscle and nerve function issues in the intestines. It’s categorized into two types:
- Primary CIPO: Congenital or resulting from injuries to the intestine’s muscle or nerves
- Secondary CIPO: Develops from conditions such as viral infections, autoimmune disorders or metabolic disorders.
The Causes of CIPO vary. Some cases are caused by genetics, but in many cases the exact cause remains unidentified.
Symptoms of chronic intestinal pseudo-obstruction
The symptoms of CIPO can change based on the affected area of the intestine. Resulting issues are similar to a blockage, including:
- Abdominal pain
- Nausea or vomiting
- Diarrhea
- Constipation
- Variations in bowel movements
- Bloating or distended abdomen.
Symptoms can range from mild and sporadic to severe, potentially causing critical health complications in young children, such as malnutrition due to poor nutrient absorption and bacterial infections.
Diagnosing chronic intestinal pseudo-obstruction
Diagnosing CIPO involves a thorough medical history and physical examination to identify any risk factors or symptoms typical of CIPO. This process may include a variety of diagnostic tests, such as imaging to check for abnormalities in the abdomen and motility studies across different parts of the gastrointestinal tract to assess the movement of food. Specific tests such as antroduodenal and colonic manometry measure bowel pressures to confirm CIPO. In unique situations, a laparotomy might be performed to inspect and take samples from the intestines directly.
Treatment of chronic intestinal pseudo-obstruction
Proper medical treatment can help stabilize the condition of pseudo-obstruction, as there is currently no known cure. This can prevent complications and improve your child’s quality of life, allowing them to participate in typical childhood activities.
Treatment options may include:
- Prokinetic medications that can aid intestinal contractions and improve motility in some children
- Antibiotics, when intestinal bacterial overgrowth is suspected
- Anti-nausea medications, anti-diarrheal medications or laxatives, when appropriate
- Medicines that target pain; however, pain medications can also slow digestion and are used sparingly for children with CIPO.
Specific medications and treatment regimens used are based on each child’s individual history.
It is crucial to provide proper nutrition to children with CIPO. Nutritional rehabilitation is a top priority for these children. It is recommended that they consume several small meals throughout the day consisting of easy-to-digest and pureed foods. In some cases, children may be unable to consume even small meals by mouth. In these cases, nutrition is given to them through a feeding tube or intravenous delivery, depending on the severity of the case.
In certain situations, the release of pressure from the intestines may require surgical decompression. This can be achieved by inserting a feeding tube directly into the stomach or by creating an opening in the abdomen through which the intestines can expel gas and empty stool.
In severe and uncommon cases, transplantation of the small bowel may be necessary to replace the intestines and potentially other organs.
