Understanding Delayed Diagnosis of Pediatric Appendicitis

Pediatric appendicitis is a serious medical condition where the appendix, a small tube-like structure attached to the large intestine, becomes inflamed and infected. It is a common cause of acute abdominal pain in pediatric patients and typically requires prompt medical attention to avoid complications such as a ruptured appendix.  Early diagnosis and treatment are critical to prevent severe complications.

What is Pediatric Appendicitis?

Appendicitis occurs when the appendix, a small, finger-shaped pouch attached to the large intestine, becomes inflamed and filled with pus. The exact cause of appendicitis is not always clear, but it is typically attributed to one of the following factors:


The most common cause of appendicitis is an obstruction in the appendix. This blockage can be due to:

    • Fecaliths: Hardened stool (fecal matter) can obstruct the appendix.
    • Enlarged lymphoid follicles: These are part of the immune system and can swell due to infection, blocking the appendix.
    • Parasites: Infections with intestinal parasites can lead to blockages.
    • Foreign bodies: Ingested objects or other material that can obstruct the appendix.


Infections in the digestive tract, such as gastrointestinal infections, can lead to swelling and inflammation of the appendix. Viral, bacterial, or fungal infections can contribute to this process.


Conditions that cause widespread inflammation in the body, such as inflammatory bowel diseases (e.g., Crohn’s disease), can also lead to appendicitis.


There may be a hereditary component, as appendicitis can sometimes run in families, suggesting a genetic predisposition to the condition.

When the appendix becomes blocked, bacteria inside the organ can multiply rapidly, causing the appendix to become inflamed, swollen, and filled with pus. If not treated, the appendix can burst, spreading infection throughout the abdominal cavity, leading to serious complications like peritonitis or abscess formation. It is most common in children and adolescents aged 10 to 19.

What are the Symptoms of Pediatric Appendicitis?

The symptoms of appendicitis can vary but commonly include:

Abdominal Pain

Starts around the navel (belly button) and then shifts to the lower right side of the abdomen.  The pain typically becomes sharper and more intense over time. Worsens with movement, coughing, or pressing on the area.

Loss of Appetite

A sudden loss of interest in eating is common.

Nausea and Vomiting

Often occurs shortly after the abdominal pain begins.
Fever: Low-grade fever that may worsen as the illness progresses.

Digestive Symptoms

Children in the early stages of appendicitis often report constipation or diarrhea; Inability to pass gas.; and/or abdominal bloating.

Other common symptoms of appendicitis include swelling in the abdomen and increased pain when walking, standing, or making sudden movements.
Appendicitis typically develops quickly, often over a few hours to a couple of days. Here is a general timeline:

Initial Phase (First 6-12 hours):

    • Mild pain starts near the belly button.
    • Nausea and possibly vomiting.
    • Loss of appetite.

Intermediate Phase (12-24 hours):

    • Pain shifts to the lower right abdomen.
    • Pain becomes more severe and localized.
    • Low-grade fever may develop.

Advanced Phase (24-48 hours):

    • Symptoms intensify.
    • Higher fever may occur.
    • The risk of the appendix bursting increases, leading to potential complications such as peritonitis (infection of the abdominal lining) or an abscess.

Appendicitis can develop quickly, with symptoms often appearing suddenly. Due to the rapid progression of appendicitis, it is important to seek medical attention promptly if appendicitis is suspected. Early diagnosis and treatment, typically involving surgical removal of the appendix, can prevent serious complications.

How do Doctors and Healthcare Professionals Diagnose Pediatric Appendicitis?

Diagnosing pediatric appendicitis involves a combination of medical history, physical examination, laboratory tests, and imaging studies. Here’s a breakdown, step by step, of the diagnostic process doctors must use to work up a patient with symptoms of appendicitis:

Medical History

Doctors begin by taking a detailed medical history, asking about the child’s symptoms, including the onset, duration, and nature of abdominal pain, as well as any associated symptoms like nausea, vomiting, fever, and changes in bowel habits.

Physical Examination

    • Abdominal Examination: The doctor will gently press on the child’s abdomen to check for tenderness, swelling, and pain localization. Pain that migrates to the lower right quadrant is a key sign.
    • Rebound Tenderness: Pain upon release of pressure on the abdomen may indicate peritoneal irritation.
    • Rovsing’s Sign: Pain in the lower right abdomen when pressure is applied to the left side.
    • Psoas Sign: Pain when the child lifts their right leg against resistance.
    • Obturator Sign: Pain when the right hip and knee are flexed and the leg is rotated internally.

Laboratory Tests

    • Blood Tests: A complete blood count (CBC) to check for elevated white blood cells (leukocytosis), which indicates infection or inflammation.
    • C-Reactive Protein (CRP): Elevated CRP levels can also indicate inflammation.

Imaging Studies

    • Ultrasound: Often the first imaging test used in children. It is non-invasive and can show an enlarged appendix, fluid around the appendix, or abscess formation.
    • CT Scan: Used if the ultrasound is inconclusive. It provides a more detailed image and can help identify appendicitis and complications such as a ruptured appendix.
    • MRI: Sometimes used, particularly to avoid radiation exposure from a CT scan. It provides detailed images and can be especially useful in pregnant or pediatric patients.

Differential Diagnosis

When making a diagnosis, doctors are required to form a differential diagnosis.  A differential diagnosis is the process by which a healthcare provider distinguishes a particular disease or condition from others that present with similar clinical features. It involves systematically considering and ruling out alternative diagnoses based on the patient’s symptoms, history, physical examination, and diagnostic tests.  Doctors also consider other conditions that can mimic appendicitis, such as:

    • Gastroenteritis
    • Mesenteric adenitis
    • Urinary tract infections
    • Constipation
    • Ovarian torsion (in female adolescents)

Doctors must rule in or out each medical condition that could explain that patient’s symptoms.


In some cases, if the diagnosis is unclear, the child may be observed in the hospital for a short period to monitor the progression of symptoms.

Combining Results

The diagnosis of pediatric appendicitis is usually confirmed by combining findings from the medical history, physical examination, lab tests, and imaging studies. Prompt and accurate diagnosis is essential to avoid complications and ensure timely treatment, typically involving surgical removal of the appendix (appendectomy).

How is Pediatric Appendicitis Treated?

Pediatric appendicitis is typically treated with surgical removal of the appendix, known as an appendectomy. Here’s a detailed overview of the treatment process you can expect if your child is diagnosed with appendicitis:

Preoperative Care

    • Diagnosis Confirmation: Once appendicitis is suspected and confirmed through medical history, physical examination, and imaging studies, the decision for surgery is made.
    • Intravenous (IV) Fluids: To prevent dehydration and maintain electrolyte balance, the child is given IV fluids.
    • Antibiotics: Broad-spectrum antibiotics are often administered before surgery to help prevent infection.

Surgical Treatment


There are two main surgical approaches to perform an appendectomy:

    • Laparoscopic Appendectomy:
      • Procedure: Small incisions are made in the abdomen, and a laparoscope (a thin tube with a camera) is inserted. Surgical instruments are used to remove the appendix through these incisions.
      • Advantages: Minimally invasive, less postoperative pain, shorter hospital stay, quicker recovery, and smaller scars.
      • Recovery: Most children can go home within 1-2 days and resume normal activities within a week or two.
    • Open Appendectomy:
      • Procedure: A single larger incision is made in the lower right side of the abdomen to remove the appendix directly.
      • Advantages: Preferred in cases where the appendix has ruptured or there is widespread infection (peritonitis).
      • Recovery: Hospital stay might be slightly longer, and recovery can take a bit more time compared to laparoscopic surgery.

Postoperative Care

    • Monitoring: The child is monitored for any signs of infection or complications.
    • Pain Management: Pain relief is provided using medications as needed.
    • Diet: Initially, a liquid diet might be recommended, gradually progressing to regular food as tolerated.
    • Activity: Encouraged to move around as soon as possible to promote recovery, but strenuous activities should be avoided until fully healed.

Treatment for Complicated Appendicitis

If the appendix has ruptured or there is an abscess:

    • Draining Abscesses: In cases where an abscess has formed, it may be drained before the appendectomy is performed.
    • Extended Antibiotics: A longer course of antibiotics may be required to treat any infection.


    • Wound Care: Instructions on keeping the surgical site clean and dry.
    • Follow-Up Visits: Scheduled to monitor recovery and remove stitches if necessary.
    • Activity Restrictions: Guidance on when the child can return to normal activities, including school and sports.

Non-Surgical Management (Rare Cases)

In some cases of uncomplicated appendicitis where surgery might not be immediately feasible (due to other medical conditions), a non-surgical approach with antibiotics alone might be considered. However, this is less common and typically followed by an elective appendectomy later.

When May a Delay in Diagnosis be Considered Medical Malpractice?

A delay in diagnosing or a failure to diagnose pediatric appendicitis can be considered medical malpractice under certain circumstances. Medical malpractice occurs when a healthcare provider deviates from the standard of care, resulting in harm to the patient. Here are key factors that might indicate medical malpractice in the context of pediatric appendicitis:

Failure to Take a Proper Medical History

    • Negligence: The healthcare provider did not thoroughly inquire about the child’s symptoms, medical history, and the progression of the illness.  For example – ignoring or dismissing reports of typical symptoms such as abdominal pain, fever, and nausea.

Inadequate Physical Examination

    • Negligence: The provider failed to perform a comprehensive physical examination. For example – missing key signs of appendicitis like localized tenderness, rebound tenderness, or specific signs like Rovsing’s or psoas signs.

Failure to Order Appropriate Diagnostic Tests

    • Negligence: Not ordering necessary tests such as blood tests, ultrasound, or CT scans when appendicitis is suspected. For example – relying solely on a basic examination without further investigation despite the presence of significant symptoms.

Misinterpretation of Test Results

    • Negligence: Misreading or failing to properly interpret diagnostic test results. For example – overlooking signs of appendicitis in imaging studies or blood work.

Delay in Referring to a Specialist

    • Negligence: Not referring the child to a pediatric surgeon or a specialist in a timely manner.  For example – delaying referral despite persistent or worsening symptoms.

Inadequate Monitoring and Follow-Up

    • Negligence: Failing to monitor the child’s condition adequately or to provide proper follow-up care.  For example – not scheduling follow-up appointments or dismissing continued symptoms without proper evaluation.

Failure to Act on Alarming Signs

    • Negligence: Ignoring or downplaying severe or alarming signs that warrant immediate intervention. For example – not taking action when the child presents with severe abdominal pain, high fever, or signs of peritonitis.

Proving Medical Malpractice

To prove medical malpractice, the following elements must be established:

    • Duty of Care: The healthcare provider owed a duty of care to the patient.
    • Breach of Duty: The provider failed to meet the standard of care expected in the medical community.
    • Causation: The breach of duty directly caused harm to the patient.
    • Damages: The patient suffered actual harm or injury as a result of the provider’s negligence.

Examples of Harm from Delayed or Missed Diagnosis Due to Medical Negligence

    • Perforation of the Appendix: Leading to peritonitis (infection of the abdominal cavity).
    • Abscess Formation: Requiring more complex treatment and longer recovery.
    • Sepsis: A severe, life-threatening infection spreading throughout the body.
    • Extended Hospitalization: Due to complications from delayed treatment.
    • Long-Term Health Issues: Potential for chronic pain or bowel problems.

Medical malpractice in the context of pediatric appendicitis typically involves a failure to meet the standard of care that leads to significant harm. If parents suspect that a delay or failure to diagnose appendicitis caused harm to their child, they should consult with a medical malpractice attorney to evaluate the case and determine if legal action is warranted.
