The Diagnostic Journey of RCPD
If you're experiencing persistent swallowing difficulties and suspect you might have retrograde cricopharyngeus disease, you're likely facing a mix of emotions—relief at potentially having answers, anxiety about upcoming tests, and perhaps frustration from months or years of unexplained symptoms. The diagnostic journey ahead may seem daunting, but understanding what to expect can help you feel more prepared and confident as you work with your healthcare team to get to the bottom of your swallowing problems.
The path to diagnosing retrograde cricopharyngeus disease is methodical and thorough, involving several specialized tests that each provide unique pieces of the puzzle. While the process may take time, each step brings you closer to understanding exactly what's happening in your throat and, more importantly, how to treat it effectively.
Understanding the Diagnostic Challenge
Retrograde cricopharyngeus disease presents a unique diagnostic challenge because its symptoms can overlap significantly with other swallowing disorders. The cricopharyngeus muscle's dysfunction—where it fails to relax properly or contracts at inappropriate times—creates symptoms that can mimic everything from esophageal strictures to neurological conditions to gastroesophageal reflux disease.
Your healthcare provider's job is to piece together your symptom pattern, physical examination findings, and test results to create a complete picture of what's happening. This detective work requires patience from both you and your medical team, but it's essential for ensuring you receive the right treatment.
The Initial Clinical Assessment
Before any imaging or invasive procedures, your doctor will conduct a comprehensive clinical assessment. This isn't just routine paperwork—it's a crucial first step that guides all subsequent testing.
Detailed Symptom History
Expect your doctor to ask detailed questions about your swallowing difficulties:
When did symptoms first appear, and have they progressed?
Which foods or liquids are most problematic?
Do you experience symptoms immediately when swallowing or after food goes down?
Where do you feel food getting stuck—throat, chest, or stomach area?
Are there positions or techniques that help or worsen symptoms?
Have you experienced weight loss, recurrent pneumonia, or voice changes?
These questions help distinguish retrograde cricopharyngeus disease from other conditions. For instance, food feeling stuck immediately in the throat area (rather than lower in the chest) suggests an upper esophageal sphincter problem like cricopharyngeus dysfunction.
Physical Examination
Your doctor will examine your head, neck, and throat, looking for:
Signs of muscle weakness or neurological problems
Throat inflammation or structural abnormalities
Lymph node enlargement that might suggest cancer
Voice quality changes that could indicate vocal cord problems
This examination helps rule out obvious structural problems and neurological conditions that could cause similar symptoms.
The Barium Swallow Study: Your First Look Inside
The barium swallow study, also called an upper GI series or modified barium swallow, is often the first imaging test ordered and provides the most comprehensive initial view of your swallowing function.
What to Expect Before the Test
Preparation: You'll typically be asked to fast for 8-12 hours before the test. Wear comfortable clothing without metal buttons or zippers, as these can interfere with the X-ray images. If you take medications, ask your doctor whether to continue them—some may need to be temporarily stopped.
Location and Duration: The test is performed in a radiology department and usually takes 30-60 minutes, depending on how many different consistencies and positions are tested.
During the Barium Swallow
The Setup: You'll stand or sit in front of a fluoroscopy machine, which takes real-time X-ray movies of your swallowing. A radiologist and often a speech-language pathologist will guide you through the process.
The Barium: You'll drink or eat various consistencies mixed with barium, a chalky contrast material that shows up brightly on X-rays. This might include:
Thin liquid barium (like water consistency)
Nectar-thick barium
Honey-thick barium
Barium-coated solid foods like cookies or marshmallows
What You'll Experience: The barium has a chalky, somewhat unpleasant taste, but most people tolerate it well. You'll be asked to swallow while the machine records X-ray movies from different angles. Don't be surprised if you're asked to swallow the same consistency multiple times—the team needs to see consistent patterns.
What the Test Reveals
For retrograde cricopharyngeus disease, the barium swallow typically shows:
Delayed opening of the upper esophageal sphincter (cricopharyngeus muscle)
Barium pooling in the throat area before eventually passing through
Multiple swallow attempts needed to clear the barium
Possible aspiration of barium into the airway
Retrograde flow of barium back up into the throat after initial swallowing
The radiologist will also look for signs of other conditions like esophageal strictures, tumors, or motility disorders that could cause similar symptoms.
Flexible Endoscopic Evaluation of Swallowing (FEES)
FEES is a specialized test that allows direct visualization of your throat and swallowing function using a thin, flexible endoscope.
Preparing for FEES
Comfort Measures: While FEES involves passing a flexible tube through your nose, most people find it more comfortable than they expected. The endoscope is very thin (about the diameter of a piece of spaghetti) and typically doesn't cause significant discomfort.
Medication: You may receive a nasal decongestant spray to shrink nasal tissues and a topical anesthetic to minimize discomfort, though many centers perform the test without anesthesia to avoid affecting swallowing function.
The FEES Procedure
Endoscope Placement: The flexible endoscope is gently passed through one nostril and positioned to give a clear view of your throat, voice box, and the entrance to your esophagus.
Swallowing Assessment: You'll be given various foods and liquids (often colored with food dye to make them more visible) to swallow while the examiner watches on a monitor. Common test materials include:
Colored water or juice
Applesauce or pudding
Crackers or cookies
Your own problematic foods brought from home
Real-Time Observation: The examiner can see exactly what happens before, during, and after you swallow, including:
Whether food or liquid pools in your throat
How well your throat muscles coordinate
If any material enters your airway (aspiration)
Whether you can clear residue effectively
What FEES Shows in Retrograde Cricopharyngeus Disease
FEES is particularly valuable for diagnosing retrograde cricopharyngeus disease because it can reveal:
Pooling of material above the cricopharyngeus muscle
Delayed or incomplete opening of the upper esophageal sphincter
Retrograde flow of swallowed material back into the throat
Aspiration events that might not be obvious to you
Compensatory behaviors you've developed to deal with the dysfunction
Esophageal Manometry: Measuring Muscle Function
Esophageal manometry measures the pressure and coordination of muscles throughout your esophagus, including the cricopharyngeus muscle.
Preparing for Manometry
Pre-test Instructions: You'll typically fast for 8-12 hours before the test. Certain medications that affect esophageal function may need to be stopped temporarily.
What to Bring: Bring a list of all medications and any specific foods that consistently cause problems, as the team may want to test these.
The Manometry Procedure
Catheter Placement: A thin, flexible catheter with pressure sensors is passed through your nose and down into your esophagus. While this sounds uncomfortable, most patients tolerate it well, especially with topical anesthetic.
Pressure Measurements: The catheter measures pressure at multiple points along your esophagus as you perform various swallowing tasks:
Dry swallows (swallowing saliva)
Water swallows of different volumes
Sometimes test swallows with different consistencies
Duration: The test typically takes 30-45 minutes, depending on how many measurements are needed.
Manometry Findings in Cricopharyngeus Disease
High-resolution manometry can detect:
Elevated resting pressure in the upper esophageal sphincter
Incomplete or delayed relaxation of the cricopharyngeus muscle
Abnormal coordination between the throat muscles and sphincter
Retrograde contractions that push material back up
These objective measurements help confirm the diagnosis and guide treatment decisions.
Advanced Imaging: CT and MRI
While not always necessary, CT scans or MRI studies may be ordered to rule out structural problems or get a more detailed view of the anatomy.
When Advanced Imaging Is Needed
Your doctor might order CT or MRI if:
There's concern about a tumor or mass
Previous tests show unusual anatomy
You have symptoms suggesting nerve or muscle disease
Conservative treatment isn't working and surgery is being considered
What These Tests Show
CT Scan: Provides detailed cross-sectional images that can reveal tumors, enlarged lymph nodes, or structural abnormalities that might not be visible on barium swallow.
MRI: Offers excellent soft tissue detail and can sometimes show muscle inflammation or nerve problems that could contribute to swallowing dysfunction.
How Doctors Differentiate from Other Conditions
One of the most important aspects of the diagnostic process is distinguishing retrograde cricopharyngeus disease from other causes of dysphagia. Here's how doctors make these distinctions:
Versus Esophageal Achalasia
Cricopharyngeus Disease:
Problems occur immediately when swallowing
Food feels stuck in the throat area
Manometry shows upper esophageal sphincter dysfunction
Barium study shows problems at the throat level
Achalasia:
Food initially goes down but then gets stuck in the chest
Progressive difficulty with both solids and liquids
Manometry shows lower esophageal sphincter problems
Barium study shows a dilated esophagus with a "bird's beak" appearance
Versus Esophageal Stricture
Cricopharyngeus Disease:
Functional problem with muscle coordination
Affects both solids and liquids similarly
No visible narrowing on imaging
Esophageal Stricture:
Anatomical narrowing of the esophagus
Solids typically more problematic than liquids
Visible narrowing on barium swallow or endoscopy
Versus Neurological Disorders
Cricopharyngeus Disease:
Usually isolated to swallowing function
No other neurological symptoms
Normal neurological examination
Neurological Disorders (stroke, ALS, etc.):
Often accompanied by other symptoms (weakness, speech problems)
Abnormal neurological examination
May affect multiple phases of swallowing
Versus GERD-Related Dysphagia
Cricopharyngeus Disease:
Swallowing difficulty is the primary symptom
Problems occur during the act of swallowing
Upper esophageal sphincter dysfunction on testing
GERD:
Heartburn and regurgitation are primary symptoms
Swallowing problems develop gradually due to inflammation
Lower esophageal problems on testing

What to Do While Waiting for Results
The diagnostic process can feel lengthy, but there are things you can do to help manage symptoms and prepare for treatment:
Keep a Symptom Diary: Track what you eat, when symptoms occur, and what seems to help or worsen them. This information is valuable for your medical team.
Stay Hydrated and Nourished: Work with your doctor or a dietitian to ensure you're getting adequate nutrition while managing symptoms safely.
Practice Safe Swallowing: Take small bites, chew thoroughly, and sit upright while eating. Don't rush meals.
Prepare Questions: Write down questions as they occur to you, so you're ready for follow-up appointments.
The Path Forward
Receiving a diagnosis of retrograde cricopharyngeus disease can bring mixed emotions—relief at finally having answers, but also concern about what treatment will involve. Remember that this condition is treatable, and most people experience significant improvement with appropriate therapy.
The comprehensive diagnostic process you've undergone provides your medical team with detailed information about your specific situation, allowing them to tailor treatment recommendations to your particular needs. Whether that involves swallowing therapy, dietary modifications, medications, or procedures, you're now equipped with the knowledge needed to make informed decisions about your care.
