Gallbladder Polyps

The exact cause is not always known. Cholesterol polyps are linked to how the body handles fats in bile. Inflammatory polyps may follow long-standing irritation of the gallbladder. Factors linked with a higher chance of a concerning polyp include older age, a single larger polyp, rapid growth, gallstones, primary sclerosing cholangitis (a scarring disease of the bile ducts) and in some regions certain ethnic backgrounds.

Polyps are found in a small proportion of adults who have an abdominal ultrasound, mostly by chance. The great majority are small and harmless.

Polyps are usually found on ultrasound. Your doctor looks at the size, number and shape of the polyp, whether it has a stalk, and whether gallstones are present. An endoscopic ultrasound (a camera-ultrasound passed through the mouth to look at the gallbladder closely) or contrast-enhanced ultrasound, CT or MRI may be used when the picture is unclear. Blood tests help check your general and liver health. A polyp cannot be biopsied easily, so the decision usually rests on imaging features.

There is no way to shrink polyps with lifestyle changes, but healthy habits support overall gallbladder health.

• Keep all follow-up ultrasound appointments

• Aim for a healthy weight; avoid crash diets

• Stay physically active

• Know the warning signs listed above and report them promptly

No special diet treats polyps, but a balanced diet is sensible.

• Eat plenty of vegetables, fruit and whole grains

• Limit heavily fried and processed fatty foods

• Keep meals regular and moderate in size

There is no medicine that removes gallbladder polyps.

• Medicines are not used to treat the polyp itself

• If you have gallstone pain, your doctor may advise a suitable pain reliever

• Avoid herbal "gallbladder cleanses"; they are not proven to help and may be harmful

The decision is between watching with repeat scans and removing the gallbladder.

• Small polyps with no worrying features are followed with ultrasound at intervals your doctor sets

• Removal of the gallbladder (usually by keyhole surgery) is advised for larger polyps, growing polyps, or when symptoms or gallstones are present

• Your surgeon will discuss the benefits and risks with you before any operation

Guidelines in recent years have refined the size thresholds at which removal is advised, and generally recommend removing the gallbladder for polyps above a certain size, for growing polyps, and for polyps in people with additional risk factors. Smaller polyps are usually followed with periodic ultrasound. Your doctor will apply the approach that fits your situation.

For most people the outlook is excellent. Small polyps often stay unchanged for years. If the gallbladder is removed, the polyp problem is resolved and most people live normally without it.

• How big is my polyp, and is it a size that needs surgery?

• How often do I need follow-up scans, and for how long?

• Do I have other risk factors that change the advice?

• What symptoms should make me contact you sooner?
