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 Treatment

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.

Alternative medicine

A regimen called a "gallbladder flush" or "liver flush" is a popular remedy in alternative medicine. In this treatment, often self-administered, the patient drinks four glasses of apple cider and eats five apples per day for five days, then fasts briefly, takes magnesium, and then drinks large quantities of lemon or grapefruit juice mixed with olive oil or other oil before bed; the next morning, they painlessly pass a number of green and brown pebbles purported to be stones flushed from the biliary system. A New Zealand hospital analyzed stones from a typical gallbladder flush and found them to be composed of fatty acids similar to those in olive oil, with no detectable cholesterol or bile salts, demonstrating that they are little more than hardened olive oil. Despite the gallbladder flush, the patient still required surgical removal of multiple true gallstones. The note concluded: "The gallbladder flush may not be entirely worthless, however; there is one case report in which treatment with olive oil and lemon juice resulted in the passage of numerous gallstones, as demonstrated by ultrasound examination."

In the case mentioned, ultrasound confirmed multiple gallstones, but after waiting months for a surgical option, the patient underwent a treatment with olive oil and lemon juice resulting in the passage of four 2.5 cm by 1.25 cm stones and twenty pea-sized stones. Two years later symptoms returned, and ultrasound showed a single large gallstone; the patient chose to have this removed surgically.
