Gallstones on ultrasound: do you need your gallbladder removed?

Your ultrasound report says “gallstones”, but you were scanned for something else and feel well.

The scan shows that stones are present. It does not, by itself, prove they are causing pain or that removing the gallbladder will help. Two people with gallstones can need different advice because their symptoms, blood tests, scan details and general health differ.

What if the gallstones are causing no symptoms?

Silent, or asymptomatic, gallstones usually do not need treatment when the gallbladder and bile ducts otherwise look normal. This is the approach recommended by NICE's gallstone disease guideline.

Your GP can review why the scan was ordered and whether you have had symptoms that fit gallstone pain. Ask whether the report mentions anything besides stones, such as a widened bile duct, inflammation, a polyp or wall changes. Those findings need their own assessment.

If observation is recommended, ask which symptoms should prompt review. New pain, fever or jaundice needs assessment.

How do you know whether pain comes from gallstones?

Gallstone pain is often felt under the right ribs or in the upper middle abdomen. It may spread towards the back or right shoulder and can follow meals. Nausea or vomiting may occur. Healthdirect describes these patterns and the warning signs below.

Bloating and indigestion alone are less specific. Reflux, stomach problems and other conditions can produce similar symptoms. If the pain pattern does not fit, further assessment may be more useful than assuming the stones explain everything.

Keep a brief record of where pain occurs, how long it lasts, its relationship to meals and any associated symptoms. Bring the ultrasound report and images, recent blood results and your medicine list to the consultation.

When is gallbladder removal usually considered?

Laparoscopic (keyhole) cholecystectomy is removal of the gallbladder through small abdominal cuts. It is commonly offered when gallstones cause symptoms, particularly repeated attacks, or when they have caused complications.

The decision should cover the likely benefit, alternatives and your individual surgical risk. It also needs to distinguish several different problems:

• Biliary colic: episodes of pain caused by temporary obstruction from a stone.
• Cholecystitis: an inflamed gallbladder, often associated with more persistent pain and sometimes fever. Acute illness needs prompt assessment; treatment may involve hospital care and surgery.
• Common bile duct stones: stones outside the gallbladder in the main drainage duct. These need a separate plan to clear the duct, even when symptoms are absent.
• Gallstone pancreatitis: inflammation of the pancreas associated with gallstones. This needs urgent hospital assessment rather than a routine booking.

Ask which problem an operation is intended to treat. The NICE guideline distinguishes symptom-free gallbladder stones from bile duct stones, for which treatment is generally recommended.

Can symptomatic gallstones be managed without surgery?

For some people, a planned period of observation and treatment for symptoms is an option. Your clinician needs to check for complications that require a different approach and explain what to do if symptoms flare up.

The C-GALL randomised trial, published in 2023, supports discussing conservative management as an option for selected adults with uncomplicated symptomatic gallstones. Its findings do not apply to every patient: people with bile duct stones, pancreatitis, obstructive jaundice or suspected cancer were among those excluded. Some participants initially managed without surgery later had an operation.

Avoiding foods that reliably trigger symptoms may help while a plan is made, but dietary change does not remove established stones. Medicines that dissolve certain stones are used only in selected circumstances, and stones can return. NIDDK's treatment information explains these limits.

Removing stones from the bile duct

Some bile-duct stones can be removed with an endoscopic procedure called ERCP. A flexible instrument passes through the mouth into the digestive tract to access the bile duct opening.

ERCP does not remove the gallbladder. Gallbladder removal may still be advised to reduce further problems from stones remaining there. The timing and sequence depend on the clinical findings and the treating team's assessment. NIDDK describes its role in duct-stone treatment.

What if the report mentions polyps or other wall changes?

These findings are different from uncomplicated gallstones. The wording and certainty of the scan matter.

Gallbladder polyps are projections from the lining. Their size, appearance, growth and individual risk factors guide whether follow-up scans or surgery are appropriate. The European joint guideline uses size and individual risk factors to guide monitoring or surgery. Guidelines differ in some thresholds, as shown by the 2025 Korean radiology recommendations, so the scan report needs to be reviewed in context. Read the separate gallbladder polyps article.

Cholesterolosis, sometimes called “strawberry gallbladder”, describes cholesterol deposits in the wall. It is often found without symptoms. The finding alone does not establish that an operation will relieve pain.

Porcelain gallbladder means calcium deposits in the wall. Advice depends on symptoms, the pattern of these deposits, general health and operative risk. It is not an automatic surgery rule for every incidental finding. A review of porcelain gallbladder management explains why the decision is individual.

Adenomyomatosis is a non-cancerous thickening of the gallbladder wall. Clearly identified, uncomplicated cases without symptoms often do not need surgery. Uncertain imaging or symptoms attributed to the gallbladder require further assessment. A British Journal of Radiology review describes the importance of distinguishing it from other causes of wall thickening.

What are the trade-offs of an operation?

Gallbladder removal can prevent further problems arising from gallbladder stones when surgery is appropriate. The liver continues to make bile afterwards, and many people manage well without a gallbladder.

Surgery has risks, including bleeding, infection, blood clots, bile leakage and injury to nearby structures or bile ducts. A stone can remain in a bile duct and need further treatment. Sometimes the safest operation requires a different approach from the one originally planned.

Symptoms may persist or need further investigation after surgery. Some people develop looser stools. Discuss this before deciding, particularly if your symptoms are not typical of gallstones. The NHS information on complications explains these possibilities.

Recovery depends on the operation, your health and the work or activities you need to resume. The treating team should explain how to build up activity and when to review your progress.

Which symptoms need urgent assessment?

Seek urgent medical assessment for severe or ongoing abdominal pain, fever or chills with pain, yellow skin or eyes, or persistent vomiting. Dark urine or pale stools also need prompt assessment, particularly alongside pain or jaundice.

Do not wait for a routine surgical appointment if these symptoms develop. If you are seriously unwell, collapse or cannot safely get to emergency care, call 000.

Questions to bring to your consultation

• Are my symptoms typical of gallstones, or could something else explain them?
• Are the stones confined to the gallbladder?
• Does the report show inflammation, a polyp or another finding that changes the advice?
• What are the benefits and risks of surgery in my situation?
• Could observation be reasonable, and what follow-up would it involve?
• Which symptoms are likely to improve, and which might remain?

Common questions about incidental gallstones

Do gallstones on an ultrasound always need surgery?

No. Symptom-free stones in an otherwise normal gallbladder and bile ducts usually do not require treatment. Other scan findings, symptoms or complications can change the advice.

Can the stones be removed while leaving the gallbladder?

Standard surgery for gallbladder stones removes the gallbladder, rather than only its stones. Stones in the common bile duct may be cleared separately, including by ERCP when appropriate.

Will gallbladder removal cure bloating?

Bloating may continue after gallbladder removal, particularly when something else is causing it. Discuss the expected benefit for each symptom before deciding.

What if there are no stones but the gallbladder does not empty normally?

When no stones are present, your clinician considers other causes of pain and tests of gallbladder function. A HIDA scan assesses bile flow and gallbladder function, but its result alone does not show that surgery will help. Read about biliary dyskinesia.
