Overview

Nonoperative management is suboptimal (ursodiol, lithotripsy). Cholecystectomy is the therapy of choice.

Medical therapy

Cholesterol gallstones can sometimes be dissolved by oral ursodeoxycholic acid. Gallstones may recur however, once the drug is stopped.

Nonsurgical approaches are used only in special situations—such as when a patient has a serious medical condition preventing surgery—and only for cholesterol stones. Stones commonly recur within 5 years in patients treated nonsurgically.

• Oral dissolution therapy. Drugs made from bile acid are used to dissolve gallstones. The drugs ursodiol (Actigall) and chenodiol (Chenix) work best for small cholesterol stones. Months or years of treatment may be necessary before all the stones dissolve. Both drugs may cause mild diarrhea, and chenodiol may temporarily raise levels of blood cholesterol and the liver enzyme transaminase.
• Contact dissolution therapy. This experimental procedure involves injecting a drug directly into the gallbladder to dissolve cholesterol stones. The drug—methyl tert-butyl ether—can dissolve some stones in 1 to 3 days, but it causes irritation and some complications have been reported. The procedure is being tested in symptomatic patients with small stones.

Treatment of biliary colic

These attacks are intensely painful, similar to that of a kidney stone attack. One way to alleviate the abdominal pain is to drink a full glass of water at the start of an attack to regulate the bile in the gallbladder, but this does not work in all cases. Another way is to take magnesium followed by a bitter liquid such as coffee or swedish bitters an hour later. Bitter flavors stimulate bile flow. A study has found lower rates of gallstones in coffee drinkers.

Pain management is an important part of treating biliary colic. Treatment is often with NSAIDs such as ketorolac (Toradol) and diclofenac (Voltaren). Hyoscine butylbromide (Buscopan) is occasionally used but is less effective than analgesics.

Contraindicated medications

Gallstone is considered an absolute contraindication to the use of the following medications:

• Fenofibrate
