Gallstones: when is surgery needed?

What's new

Gallstones are common and are often found by chance on an ultrasound done for another reason. Current guidelines advise that gallstones that have never caused symptoms usually do not need surgery. For people who develop gallstone pancreatitis (inflammation of the pancreas caused by a stone), research has shown that removing the gallbladder during the same hospital stay, once a mild attack has settled, lowers the chance of another serious attack compared with waiting weeks.

What this means for you

Go to the Emergency Department right away if you have abdominal pain that lasts more than a few hours, fever or chills, yellowing of the skin or eyes, or dark urine.

Talk to your surgeon

Your surgeon will review your symptoms and ultrasound to help you decide whether surgery is right for you. Summit Surgical sees patients by referral only — ask your family doctor or another physician to fax a referral to 587-392-0375.
