Intussusception
Intussusception
Overview
Intussusception is a serious medical condition where a part of the intestine slides into an adjacent part, resembling a telescope folding in on itself. This can lead to intestinal obstruction, causing swelling, inflammation, and potential intestinal injury.
Occurrence and Causes
- Although intussusception can occur anywhere in the gastrointestinal tract, it most commonly happens at the junction of the small and large intestines.
- The exact cause of intussusception is unknown, but it is often preceded by a virus that causes swelling of the intestinal lining.
- In some children, it may be caused by congenital conditions like a polyp or diverticulum.
- In adults, intussusception is typically the result of a medical condition or procedure, such as a polyp or tumor, scar-like tissue in the intestine (adhesions), weight-loss surgery like gastric bypass, or swelling in the intestines due to diseases like Crohn’s disease.
Risk Factors
- Certain conditions can increase the risk of intussusception, including cystic fibrosis, Henoch-Schonlein purpura (also known as IgA vasculitis), Crohn’s disease, and celiac disease.
Symptoms
- Symptoms of intussusception include severe, crampy abdominal pain that may come and go, vomiting, bloating, and bloody stool.
- The pain may last for 10 to 15 minutes or longer, followed by periods of 20 to 30 minutes with no pain, after which the pain returns.
- As the symptoms persist, some children may become lethargic (feel very tired).
- Small children might draw their knees to their chest during episodes of pain.
Treatment and Prognosis
- Intussusception is a surgical emergency and is usually treated non-surgically with a positive outcome.
- Cases not reducible by air or barium enema may require surgery.
- Typically, no bowel resection is needed.
- Complications after surgery are rare, and recurrences are very rare.
- If left untreated, however, this condition can be fatal within 2-5 days.
Intussusception: Incidence and Demographics
Age and Gender Distribution
- Intussusception primarily affects infants and toddlers, with the peak incidence occurring between 4 and 36 months of age.
- It is the most common cause of bowel obstruction in children aged 6 months to 3 years.
- Boys are more likely to be affected than girls.
Incidence in Different Regions
- In the United States, about 2,000 children in their first year of life are affected by intussusception annually.
- Globally, the incidence varies:
- In Iran: 66.54 cases per 100,000 children under one year and 31.61 cases per 100,000 children under five years.
- In Italy: 21 cases per 100,000 children, with a higher rate in boys (23 per 100,000) compared to girls (19 per 100,000).
- In South India: 61.2% of cases occur in the first year of life, with a male to female ratio of 3.4:1.
- In China: The average annual hospitalization incidence for children under 2 years is 112.9 per 100,000.
Seasonality and Associated Infections
- There is no clear seasonality associated with intussusception.
- Bacterial infections, especially bacterial enteritis, are linked to intussusception, often occurring within the first month following the infection.
Pathological Causes
- In about 25% of cases, an underlying pathological cause can be identified.
Association with Rotavirus Vaccine
- The introduction of the rotavirus vaccine has been associated with a slight increase in the incidence of intussusception in some studies, although this is still a subject of ongoing research.
Intussusception: Causes and Risk Factors
Overview
Intussusception is a medical condition where a part of the intestine slides into an adjacent part. The exact cause is not fully understood, but several factors have been associated with its occurrence.
Idiopathic Cases
- In many cases, intussusception is idiopathic, meaning it occurs without a known cause.
- Approximately 25% of cases have an identifiable underlying pathological cause.
Pathological Causes
- Pathological causes create a lead point in the intestinal wall, making it easier for the bowel to telescope.
- Conditions contributing to these lead points include Meckel’s diverticulum, polyps, and appendicitis.
Infections
- Viral or bacterial gastrointestinal infections often precede intussusception.
- Swelling of the infection-fighting lymph tissue in the intestines can lead to intussusception.
Anatomical Factors
- In children under 3 months or over 5 years, intussusception is more likely to be caused by underlying conditions such as enlarged lymph nodes, tumors, or blood vessel problems in the intestines.
Adult Cases
- In adults, intussusception is usually due to a medical condition or procedure, including:
- Polyps or tumors.
- Scar-like tissue in the intestine (adhesions).
- Weight-loss surgery such as gastric bypass.
- Swelling in the intestines from diseases like Crohn’s disease.
- Other predisposing conditions in adults include anorexia nervosa and malabsorption syndromes, which can increase intestinal flaccidity leading to intussusception.
Risk Factors
- Certain disorders can increase the risk of intussusception, including cystic fibrosis, Henoch-Schonlein purpura (IgA vasculitis), and celiac disease.
Conclusion
- While these factors are associated with intussusception, they do not necessarily cause the condition, and the exact mechanisms leading to intussusception are still not fully understood.
Signs and Symptoms of Intussusception
Intussusception presents with a distinctive set of signs and symptoms, often intense and distressing, especially in young children. The key indicators include:
- Severe, Crampy Abdominal Pain: The pain is typically intermittent, described as crampy in nature, and can be severe enough to cause significant distress.
- Vomiting: This is a common symptom and may accompany the abdominal pain.
- Bloating: The abdominal area may appear swollen or distended.
- Bloody Stool: The presence of blood in the stool is a significant sign and can indicate internal intestinal damage.
- Intermittent Pain Episodes: The pain usually lasts for 10 to 15 minutes, followed by pain-free intervals of 20 to 30 minutes before the pain returns.
- Lethargy in Children: After experiencing symptoms for some time, children may become lethargic or extremely tired.
- Knee-Chest Position in Small Children: As a response to the pain, small children often instinctively draw their knees up to their chest during episodes of pain.
These symptoms, particularly when they occur together, can be indicative of intussusception and warrant immediate medical attention to avoid complications.
Pathogenesis of Intussusception
Overview
Intussusception is a medical condition characterized by a part of the intestine sliding into an adjacent part, creating a blockage or obstruction. This process is often likened to the “telescoping” of the intestine.
Mechanism of Development
- The exact pathogenesis of intussusception is not completely understood, but it is thought to be due to an imbalance in the longitudinal forces along the intestinal wall.
Role of Lead Points
- In many cases, intussusception is triggered by a lead point, which could be a mass or a disorganized pattern of peristalsis.
- These lead points can be caused by various factors such as infections, anatomical anomalies, and altered motility.
- Bacterial or viral gastrointestinal infections can cause swelling of the lymph tissue in the intestine, potentially leading to intussusception.
Progression and Symptoms
- As intussusception develops, the mesentery (tissues attaching the intestines to the abdominal wall) is dragged into the bowel.
- This results in swelling and inflammation that can lead to intestinal injury.
- The obstruction hinders food passage, causing severe abdominal pain.
Potential Complications
- Untreated intussusception can result in severe complications, including:
- Intestinal obstruction.
- Dehydration.
- Lack of blood flow to the affected part of the intestine, leading to tissue death.
- A perforation or hole in the intestinal wall.
- Peritonitis (infection of the abdominal cavity lining).
- Sepsis (a severe response to infection).
- Shock.
Summary
The pathogenesis of intussusception involves the inward sliding of a segment of the intestine, often initiated by a lead point. This leads to an obstruction with various symptoms and can result in serious complications if not promptly treated.
Diagnosis of Intussusception
The process of diagnosing intussusception involves several steps, combining clinical assessment with imaging techniques:
Clinical Assessment
- History and Physical Examination: A thorough evaluation of the patient’s history and a physical examination are the first steps.
- Physical Findings: The healthcare provider may detect a sausage-shaped lump in the abdomen. A classic physical sign is the presence of a right hypochondrium sausage-shaped mass and emptiness in the right lower quadrant, known as Dance’s sign.
Imaging Studies
- Ultrasound: Often the first imaging modality used. It may reveal a “bull’s-eye” or “target” sign, indicative of intussusception.
- X-ray: Can be helpful but may not always show clear signs of intussusception.
- Computerized Tomography (CT) Scan: Provides more detailed images and can be used to confirm intestinal obstruction.
- Point-of-Care Ultrasound (POCUS): Reported to have high sensitivity and specificity for diagnosing intussusception.
Considerations in Imaging
- Normal Radiographs: A normal abdominal X-ray should not rule out intussusception, as it might appear indeterminate or normal.
- Transverse Ultrasonograms: These may show a mass with a swirled appearance, reflecting the loop-within-a-loop structure of the intussuscepted bowel.
Diagnostic and Therapeutic Procedure
- Contrast or Air Enema: This can be both diagnostic and therapeutic. It involves introducing air or a water-soluble contrast medium into the rectum and colon under fluoroscopic control. If successful, this procedure can reduce the intussusception, potentially avoiding the need for surgery.
In summary, the diagnosis of intussusception is a combination of clinical evaluation and imaging studies, with ultrasound being a primary diagnostic tool. In certain cases, a contrast or air enema not only assists in diagnosis but can also serve as a treatment.
Differential Diagnosis of Intussusception
Intussusception shares symptoms with several other medical conditions, making its diagnosis challenging. The following conditions are commonly considered in the differential diagnosis due to their similar presentations:
Acute Gastroenteritis
- Presents with abdominal pain and vomiting.
- The pain is usually less severe and more diffuse compared to intussusception.
Rectal Prolapse
- Intussusception may present with prolapse of the intussusceptum through the anus, resembling rectal prolapse.
- Careful examination is needed to differentiate between the two.
Milk Allergy
- Can cause gastrointestinal symptoms in infants and young children, potentially mimicking intussusception.
Incarcerated Hernia
- Causes severe abdominal pain and vomiting, similar to intussusception.
Internal Hernia
- A rare cause of intestinal obstruction with symptoms resembling those of intussusception.
Adhesive Band
- Can lead to intestinal obstruction, presenting with symptoms similar to intussusception.
Volvulus
- Involves a twist in the bowel causing obstruction.
- Presents with severe abdominal pain and vomiting.
Meckel Diverticulum
- A congenital condition that can cause gastrointestinal bleeding and abdominal pain.
Retroperitoneal Hemorrhage
- Can cause severe abdominal pain, similar to the pain experienced in intussusception.
Other Causes
- Various other causes of abdominal pain or gastrointestinal bleeding should also be considered.
A thorough history, physical examination, and appropriate diagnostic tests are crucial for differentiating intussusception from these conditions. The similarity of symptoms across these conditions underscores the importance of careful medical evaluation for accurate diagnosis.
Treatment of Intussusception
Intussusception treatment is typically approached as a medical emergency due to the risk of severe complications like dehydration, shock, and infection, which can occur if a portion of the intestine becomes necrotic (dies) due to lack of blood supply.
Non-Surgical Reduction
- First-Line Treatment: The primary treatment for intussusception is non-surgical reduction.
- Methods: This can be achieved with a water-soluble contrast enema or an air-contrast enema.
- Effectiveness: These procedures not only confirm the diagnosis but also resolve the condition in about 90% of cases in children, often eliminating the need for further treatment.
- Limitations: This procedure is not suitable if there is intestinal perforation.
- Recurrence: Intussusception can recur in up to 20% of cases, necessitating repeated treatment.
Surgical Intervention
- Indications: Surgery is considered when non-surgical reduction is unsuccessful or in the presence of complications like perforation or a lead point.
- Adult Treatment: In adults, it typically involves the resection of the involved bowel segment.
- Reduction Techniques: In some cases, the intussusception may be manually reduced (milked out) during surgery, allowing for limited resection.
- Children’s Treatment: In children, if manual reduction is not feasible or if there is perforation, a segmental resection with an end-to-end anastomosis is performed.
- Laparoscopy: This minimally invasive technique is increasingly being used in the surgical treatment of intussusception.
Supportive Care
- Pain Management: Adequate pain control is essential.
- Antiemetics: To manage vomiting and nausea.
- IV Hydration: To prevent or treat dehydration.
- Antibiotics: May be used depending on the patient’s condition, particularly if infection or peritonitis is suspected.
In summary, the treatment of intussusception typically involves a combination of non-surgical reduction techniques, surgical intervention when necessary, and supportive care to manage symptoms and prevent complications.
Prognosis of Intussusception
The outcome of intussusception largely depends on the timeliness of diagnosis and treatment. Here are the key aspects of its prognosis:
Children
- High Success Rate: With early diagnosis and appropriate treatment, the mortality rate in children is less than 1%.
- Effectiveness of Non-Surgical Reduction: Non-surgical methods like water-soluble contrast enema or air-contrast enema have a success rate of more than 80%.
- Recurrence Rate: Recurrence can happen in up to 10% of cases, often within 72 hours after the initial event, although it can occur as late as 36 months later.
Complications if Untreated
- Rapid Deterioration: If left untreated, intussusception can be fatal within two to five days.
- Increased Risk with Prolonged Prolapse: The longer the intestinal segment is prolapsed and without blood supply, the less effective non-surgical reduction becomes.
- Risk of Bowel Ischemia and Necrosis: Prolonged intussusception can lead to bowel ischemia and necrosis, potentially requiring surgical resection.
Adults
- Delayed Diagnosis Risks: In adults, diagnosis may be delayed due to vague symptoms and a wide differential diagnosis.
- Potential for Life-Threatening Complications: Adult cases have a higher risk of severe complications like peritonitis, bowel ischemia, necrosis, perforation, sepsis, and tumor seeding (particularly post-surgical).
Summary
The prognosis for intussusception is generally excellent when promptly diagnosed and treated. However, delays or failure in treatment can lead to severe, potentially fatal complications. Recurrences are possible and necessitate further treatment. The prognosis in adults can be more complicated due to the potential for delayed diagnosis and severe complications.
