Diagnosing Achalasia (Cardiospasm)
Achalasia is a rare disorder that affects the esophagus, making it hard to swallow. It happens when the lower esophageal sphincter (LES), the ring-shaped muscle at the bottom of the esophagus, doesn’t relax properly, which prevents food and liquid from passing into the stomach. This causes food to back up in the esophagus, leading to symptoms like difficulty swallowing, chest pain, and regurgitation.
To diagnose achalasia, several examinations, screening tests, and procedures are typically performed. These help confirm the diagnosis and determine the type, severity, or stage of the condition. The following are commonly used:
- Medical History: Your healthcare provider will gather information about your symptoms, medical history, and any previous diagnoses. This helps in understanding your overall health and identifying potential risk factors for achalasia.
- Physical Examination: During a physical exam, your healthcare provider will look for physical signs of a medical problem, such as weight loss, difficulty swallowing (dysphagia), regurgitation, or chest pain.
- Diagnostic Imaging Studies: Imaging studies allow doctors to look inside your body and gather clues to help diagnose and manage achalasia. The type of imaging study chosen depends on your symptoms and the area of the body being examined. Common imaging tests include:
- X-ray: A barium swallow test is often performed where you swallow a liquid containing barium that coats the inside of your esophagus. X-rays are then taken to evaluate the shape and function of your esophagus.
- Magnetic Resonance Imaging (MRI): This imaging technique uses powerful magnets and radio waves to create detailed images of your esophagus and surrounding structures.
- Laboratory Tests: Your healthcare provider may order laboratory tests to check samples of your blood, urine, or body tissues. These tests help rule out other conditions with similar symptoms.
- Esophagogastroduodenoscopy (EGD): This procedure involves inserting a thin, flexible tube with a camera at the end (endoscope) through your mouth into your esophagus. It allows doctors to visualize the inside of your esophagus and look for any problems.
- Manometry: Manometry is a diagnostic test that measures the pressure inside your esophagus while you swallow. It helps evaluate how well the muscles in your esophagus are working and can confirm a diagnosis of achalasia.
- High-Resolution Manometry: This advanced test gives more detailed information about how the esophageal works by measuring pressure at several points along the esophagus at the same time. It can help doctors predict how well treatments might work and guide decisions for managing achalasia.
Specialists involved in diagnosing achalasia may include gastroenterologists (doctors who specialize in digestive system disorders) and surgeons who specialize in treating conditions affecting the esophagus.
Additional examinations, tests, or procedures may be done to determine the type, severity, or stage of achalasia:
- Esophageal biopsy: In some cases, a small tissue sample may be taken from the lining of your esophagus during an endoscopy procedure to rule out other conditions.
- pH Monitoring: This test measures acid levels in your esophagus over a 24-hour period using a small device inserted into your esophagus through your nose.
These additional tests help identify specific factors or signs related to the type, severity, or grade of achalasia and assist in creating a treatment plan tailored to each individual's needs. Remember to consult with a healthcare professional who can provide personalized advice based on your specific situation before pursuing any diagnostic tests or procedures.
