The Stone-Free Gallbladder That Still Causes Pain

Modern medicine loves clarity. When a test lights up, we act. When it’s blank, we relax.

It’s almost as if, unless something shows up on a scan, it simply doesn’t exist.

CT scans and ultrasounds have become the new oracles—the sacred truth-tellers of our age. If the scanner says it’s fine, who are we to argue?

But medicine isn’t always that simple.

Because sometimes, patients experience real pain even when every test and every image looks perfectly normal. In gastroenterology, one such enigma lies within a small pear-shaped organ—the gallbladder.

So, can a gallbladder cause pain even when no stones are visible?

The answer, surprisingly, is yes.

When the Gallbladder Hurts Without Stones

Two main conditions can cause gallbladder pain in the absence of visible stones:

• Functional Gallbladder Disorder

• Acalculous Cholecystitis

Let’s start with the first.

Functional Gallbladder Disorder: When the Problem Is Motion, Not Matter

Previously called biliary dyskinesia, this condition looks deceptively normal on scans. The gallbladder appears structurally fine, but functionally, it isn’t. That’s because it doesn’t contract effectively to release bile after meals—especially fatty ones.

Think of it like a car engine that looks new but refuses to start.

The bile may be too thick or cholesterol-rich, or the gallbladder’s muscles might not coordinate properly. And the result? Pain—specifically biliary colic, a steady ache in the upper right abdomen that can mimic classic gallstone symptoms.

What’s happening inside is simple: after a rich meal, the gallbladder tries to empty, fails to do so completely, pressure builds up, and pain follows.

Diagnosing a Problem That Doesn’t Show Up

Functional gallbladder disorder is largely a diagnosis of exclusion.

Doctors must rule out every other cause of upper abdominal pain—through blood tests, ultrasound, and detailed clinical evaluation.

If, during the process, the gallbladder starts showing sludge or tiny stones, the diagnosis becomes clearer. But until then, it hides behind normal test results and frustrated sighs.

A Story from Practice

During India’s second COVID wave, I saw a 45-year-old man who had endured six years of upper abdominal pain. All his scans were normal. He had been labeled “anxious” or “functional” and told nothing was wrong.

I re-evaluated him, studied the literature, and eventually performed gallbladder surgery.

The outcome was remarkable—his pain vanished.

That experience taught me humility. Doing hundreds of gallbladder surgeries doesn’t automatically make one an expert on the gallbladder. Technical mastery is not the same as clinical insight. True understanding demands curiosity and lifelong learning.

Why Thinking Must Evolve in Medicine

Medicine changes faster than we care to admit.

Twenty years ago, gut microbes were dismissed as useless germs. Today, they’re central to our understanding of immunity, metabolism, and even mental health.

It’s a humbling reminder: what we don’t understand, we often ignore.

And in doing so, we risk missing the truth sitting quietly in plain sight.

The same applies to functional gallbladder disorder. Awareness, not dismissal, is the key.

The Tests We Can Use—And Their Limits

When scans look normal but symptoms persist, doctors may evaluate gallbladder function using:

• Fatty-meal cholescintigraphy

• Fatty-meal functional ultrasound

These measure the organ’s activity before and after a fatty meal, calculating something called gallbladder ejection fraction—a percentage that shows how well it empties. Low ejection fractions may suggest poor contractility.

However, these tests aren’t perfect. Results can vary, and interpretation still relies heavily on clinical judgment and symptom history.

If symptoms are mild or infrequent, observation is preferred. But when pain is persistent for more than three months or significantly affects quality of life, gallbladder removal may be needed—and often helps.

Acalculous Cholecystitis: The Silent and Serious Kind

The second condition—acalculous cholecystitis—is far less common but far more dangerous. Here, the gallbladder is inflamed without any stones blocking its ducts.

It usually strikes critically ill patients—those recovering from major trauma, burns, sepsis, or long ICU stays. Even prolonged fasting or resting the gut on IV nutrition (TPN) can increase risk.

The underlying reason is reduced blood supply to the gallbladder wall, compounded by bile stagnation. Together, they trigger inflammation—and sometimes infection.

Why It’s More Serious

Because the gallbladder’s blood flow is already compromised, tissue death (gangrene), rupture, and sepsis can occur much faster than in stone-related cholecystitis. And detecting it early is difficult, since symptoms often get masked under other illnesses.

How It’s Managed

Acalculous cholecystitis is an emergency. Prompt treatment can save lives.

The usual approach involves:

• Hospitalization and supportive care with IV fluids, antibiotics, and pain control

• Gallbladder drainage through a thin tube inserted via the skin for unstable patients

• Definitive gallbladder surgery if the patient is strong enough

“Diagnosis Is Rarely Black or White”

Medicine often lives in grey zones.

A patient with gallstones might have no pain at all. Someone with a normal scan might be in agony due to gallbladder issues.

Jeffrey Archer once wrote, “Few things are entirely black or white, but more often different shades of grey.”

The same truth applies here.

Functional gallbladder disorder accounts for nearly 20 percent of adult gallbladder surgeries in the U.S., and up to 50 percent in children—That might suggest a possible overusage of the diagnosis. In India, it’s less commonly identified, perhaps because clinicians remain cautious about labeling invisible conditions. That caution has its benefits—but awareness matters too. Because for the patients who truly have it, diagnosis and treatment can be transformative.

Seeing Beyond the Image

There’s an old saying: “Eyes do not see what the mind does not know.”

Modern imaging helps us see better—but only when the mind is open enough to recognize what it’s looking at.

Not every disease leaves a mark on a scan.

Sometimes, the truth lies between pixels—in patterns, in symptoms, in listening, and in thought.

So, while the CT scan may be our modern oracle, it’s still human insight that must interpret what it says—and, more importantly, what it doesn’t.

Until next time—stay curious, stay kind, and trust your gut.
