Can You Have a Gallbladder Attack Without a Gallbladder?

Pain that feels exactly like a gallbladder attack can happen even after your gallbladder has been surgically removed. Doctors call this postcholecystectomy syndrome, and it encompasses a range of symptoms, from sharp biliary-type pain to bloating and nausea, that persist or develop after surgery. The causes are surprisingly varied, and many of them are treatable once correctly identified.

What Postcholecystectomy Syndrome Actually Means

Postcholecystectomy syndrome (PCS) is an umbrella term rather than a single diagnosis. It covers any combination of upper abdominal pain, jaundice, or digestive symptoms that show up in someone whose gallbladder is already gone.¹ The label exists because gallbladder removal, though it is one of the most common surgeries worldwide, sometimes fails to relieve symptoms entirely.² That can feel bewildering if you were told the surgery would fix the problem for good.

A recent systematic review and meta-analysis found that preoperative symptoms and psychological factors like anxiety or depression were among the strongest predictors for developing PCS, and that the type of surgery matters too: open procedures carry higher risk than laparoscopic ones.³ The presence of a residual cystic duct stump was also flagged as a technical risk factor. In short, some people are more vulnerable to post-surgical symptoms than others, and the reasons span anatomy, surgical technique, and even mental health.

Stones That Get Left Behind or Form After Surgery

The most straightforward explanation for a “gallbladder attack” without a gallbladder is a stone lodged in the common bile duct. When surgeons remove the gallbladder, tiny stones can slip into the bile duct during the operation itself, or they may already be sitting there undetected. In one study of nearly 1,500 patients who had laparoscopic gallbladder removal, about 1.8% needed a follow-up procedure to retrieve retained bile duct stones, with a median gap of roughly five months between surgery and discovery.⁴ A separate study put the rate at about 2.3% and found that patients whose original gallstones were small, around 5 mm, were more likely to end up with retained duct stones than those with larger stones.⁵

The mechanisms are varied. Stones can migrate from the gallbladder into the duct between the time of your last imaging and the day of surgery. They can get pushed into the duct during the operation. Or radiolucent stones, the kind that do not show up well on imaging, may already be there but invisible to scans. New stones can even form in the bile duct itself after the gallbladder is gone.⁴ Because of these possibilities, surgeons often advise patients, especially those who originally had multiple small gallstones, that duct stones could surface months or even years later.

The Cystic Duct Stump Problem

When surgeons cut away the gallbladder, they leave behind a short stump of the cystic duct, the tube that once connected the gallbladder to the main bile duct. In most people this tiny remnant causes no trouble. But stones can form inside it, or a stone can be left behind in it, and the result feels a lot like the original gallbladder attacks.⁶ This problem demands a higher level of suspicion from doctors, because it does not always come to mind when a patient without a gallbladder shows up with biliary pain.⁷

Estimates of how often cystic duct remnant stones cause postcholecystectomy symptoms range widely, from under 2.5% to as high as 16% of patients who undergo gallbladder removal.⁸ The length and shape of the stump matters: the more tissue left behind, the more room there is for stones to develop. This is one area where surgical technique makes a real difference, and it lines up with the meta-analysis finding that a residual cystic duct is an independent risk factor for PCS.³

Sphincter of Oddi Dysfunction

Even when no stones are involved, the valve at the bottom of the bile duct can malfunction. The sphincter of Oddi is a tiny muscular ring that controls the flow of bile and pancreatic juice into the small intestine. When it spasms or stays clamped shut, bile backs up and triggers pain that mimics a classic gallbladder attack. This is called sphincter of Oddi dysfunction, and it is a recognized cause of chronic biliary pain after gallbladder removal.⁹ The pathophysiology is still not fully understood, which makes it frustrating both for patients and their doctors.¹⁰

Diagnosing sphincter of Oddi dysfunction is genuinely difficult. The current gold standard is manometry, a pressure measurement taken during an endoscopic procedure, but even manometry can be misleading. A systematic review found that non-invasive tests have poor sensitivity and specificity compared to manometry, and there is limited data on how well any of these tests predict which patients will actually improve with treatment.¹¹ When imaging and blood tests come back normal but the pain keeps returning, sphincter of Oddi dysfunction is often where the diagnostic trail leads.

When the Pain Is Not Biliary at All

Not every post-surgery pain comes from the bile ducts. Some symptoms attributed to a “gallbladder attack” after cholecystectomy turn out to have entirely different origins. Two categories deserve attention: bile acid malabsorption and changes in gut function.

Without a gallbladder to store and concentrate bile, your liver delivers a steady drip of bile directly into the small intestine. If more bile acids reach the colon than it can handle, they trigger the lining to secrete extra water and electrolytes, which can cause watery diarrhea and cramping.¹² This is bile acid malabsorption, and while it does not feel like the sharp right-sided colic of a classic gallbladder attack, the bloating and abdominal discomfort can be intense enough that people fear something has gone wrong with the surgery. The good news is that bile acid sequestrants, medications that bind excess bile acids in the gut, often provide relief.

Cholecystectomy also appears to raise the risk of irritable bowel syndrome. A large prospective study using the UK Biobank found that people who had undergone gallbladder removal had roughly a 46% higher risk of developing IBS over a median follow-up of about 13 years, compared to those who had not had the surgery. The risk was especially pronounced for the diarrhea-predominant subtype.¹³ The association held regardless of whether the patient originally had gallstones, suggesting it is the loss of the gallbladder itself, and the resulting change in bile flow, rather than the underlying gallstone disease that drives the increased risk.

Gallstone Pancreatitis After Gallbladder Removal

In rare cases, a retained bile duct stone does more than cause pain; it can block the pancreatic duct and trigger pancreatitis. This is the same mechanism that causes gallstone pancreatitis in people who still have their gallbladders, except the stones are now duct stones rather than gallbladder stones. A case report described a 38-year-old woman who developed gallstone pancreatitis just three weeks after laparoscopic cholecystectomy. Endoscopy revealed stones in the distal common bile duct, which were successfully removed.¹⁴ This scenario is uncommon, but it underscores why sudden, severe upper abdominal pain radiating to the back after cholecystectomy warrants urgent medical attention.

Early Versus Late Symptoms

The timing of symptoms after gallbladder removal gives doctors a useful clue about the cause. Symptoms that appear in the first few weeks tend to stem from surgical complications or incomplete surgery: a retained stone, a bile leak from the cystic duct stump, or an injury to the bile duct. Symptoms that develop months or years later are more often caused by new stone formation, inflammatory scarring that narrows the bile duct, or sphincter of Oddi dysfunction.¹⁵

If you develop sharp, colic-like pain within days of surgery accompanied by fever or yellowing skin, that raises concern about a bile leak or an acute retained stone. Pain that creeps back six months later and comes in waves after fatty meals is more suggestive of a new duct stone or sphincter dysfunction. And ongoing loose stools or bloating without classic biliary colic points toward bile acid malabsorption or gut motility changes. These timing patterns are not absolute rules, but they help steer the workup in the right direction.

How the Diagnosis Gets Sorted Out

The workup for post-cholecystectomy symptoms usually starts with blood tests, specifically liver function tests and pancreatic enzymes, plus an ultrasound. When these are inconclusive, magnetic resonance cholangiopancreatography (MRCP) is a noninvasive imaging option that can reveal retained stones, bile duct strictures, or abnormalities in the cystic duct remnant.¹⁵

If imaging suggests a stone or stricture, endoscopic retrograde cholangiopancreatography (ERCP) can both confirm the diagnosis and treat the problem in a single procedure. In one early series, ERCP successfully removed common bile duct stones in 23 patients after laparoscopic cholecystectomy and managed bile duct leaks with temporary stenting in others.¹⁶ For suspected sphincter of Oddi dysfunction, manometry during ERCP remains the standard diagnostic test, even though its accuracy diminishes in milder subtypes.¹¹

The challenge is that when all the imaging and lab work comes back normal, doctors are left distinguishing between sphincter of Oddi dysfunction, bile acid malabsorption, functional gut disorders, and other upper-GI conditions. Non-invasive tests for sphincter dysfunction, like fatty meal sonography and hepatobiliary scintigraphy, correlate poorly with manometry results and with each other.¹⁷ This is where the diagnostic process can stall, and why second opinions from a gastroenterologist who specializes in biliary disorders can be valuable.

Anatomical Variations That Complicate Surgery

The biliary system is not anatomically identical from one person to the next, and these variations affect both the difficulty of surgery and the risk of post-surgical problems. In one study, about 30% of patients had abnormal anatomical variations in their bile ducts, including short cystic ducts, unusual insertion points, accessory ducts, and small ducts connecting the liver directly to the gallbladder bed. Biliary tract injuries were significantly more common in patients with abnormal anatomy.¹⁸ An accessory duct that goes unrecognized during surgery, for example, can leak bile afterward and produce symptoms that feel indistinguishable from the original gallbladder problem.

You will not know beforehand whether your anatomy is textbook or unusual. But if post-surgical symptoms keep defying explanation, unusual anatomy is one possibility your surgical team should consider, especially if the MRCP or ERCP shows features that were not anticipated from the original operative report.

What Happens in Children and Adolescents

Gallbladder removal in children and teenagers has become more common as childhood obesity rates have risen, and the post-surgical picture looks broadly similar to adults, though the data is thinner. In one pediatric study, roughly 37% of young patients developed postcholecystectomy syndrome. The most common complaints were diarrhea, bloating, and heartburn. Children who were overweight were significantly more likely to develop PCS than those at a healthy weight. Despite the high rate of ongoing symptoms, about 77% of the children were still satisfied with the surgery overall, though satisfaction dropped to about 57% among those with PCS.¹⁹

The takeaway for parents is that pediatric gallbladder removal carries real benefits, but ongoing digestive symptoms are not unusual and should prompt follow-up rather than dismissal. As in adults, many of these symptoms reflect bile acid changes or gut motility shifts rather than a surgical complication requiring a return to the operating room.

The Role of Nerve Sensitization

Before surgery, chronic gallbladder inflammation can sensitize the nerves in the skin and abdominal wall overlying the gallbladder. In one study, somatosensory hyperalgesia in the referred pain area was found in 84% of patients before cholecystectomy. After uncomplicated surgery, this hypersensitivity resolved and none of the patients had lingering pain complaints.²⁰ That is reassuring for most patients. But it also hints at what can go wrong: if surgery is delayed or the inflammation was long-standing, nerve sensitization may persist even after the gallbladder is gone. In these cases the pain is real but its origin is neural rather than structural, and treating it requires a different approach than looking for stones or strictures.

Some researchers have drawn parallels to phantom limb pain, where the brain continues to register pain from a body part that no longer exists. The evidence for a true “phantom gallbladder” phenomenon is limited, but the broader principle of central sensitization, where the nervous system amplifies pain signals even after the original trigger is removed, is well established in other surgical contexts. If you have ongoing right upper quadrant pain with completely normal imaging and lab results, a pain specialist may be worth consulting alongside your gastroenterologist.

A Bile Metabolism Problem That Exists Independently

There is also a pattern of biliary-type pain that has nothing to do with the gallbladder itself, either before or after removal. Some patients experience dull aching in the liver region punctuated by severe colic that resembles a gallbladder attack, driven by underlying disturbances in cholesterol and bile acid metabolism in the liver. This condition can appear at any time, whether or not the gallbladder has been removed.²¹ For these patients, the surgery was never going to be the cure, because the gallbladder was not the source of the pain in the first place. Recognizing this pattern matters because it redirects treatment toward managing the metabolic disorder rather than chasing surgical explanations.

Psychological Factors and Symptom Persistence

The meta-analysis on PCS risk factors found that preoperative anxiety and depression were among the most significant predictors of post-surgical symptoms, with high effect sizes that held up after adjusting for other variables.³ This does not mean the pain is imagined. Psychological distress genuinely amplifies how the brain processes pain signals, and it can worsen gut motility problems independently. If you dealt with significant anxiety or depression before your surgery, addressing those conditions directly, whether through therapy, medication, or both, may do more for your post-operative comfort than another round of imaging.

This finding also raises practical questions about pre-surgical screening. If we know that patients with high anxiety levels are more likely to remain symptomatic, there is a case for addressing those factors before the surgery rather than after, or at minimum setting realistic expectations about what the operation is likely to accomplish. That conversation rarely happens in the hurried lead-up to a scheduled cholecystectomy, but the evidence suggests it should.
