Treatment
Acute pain from gallstones and gallbladder disease is usually treated in the hospital, where diagnostic procedures are performed to rule out other conditions and complications. There are three approaches to gallstone treatment.
- Expectant management ("wait and see")
- Nonsurgical removal of the stones
- Surgical removal of the gallbladder
Expectant Management
Guidelines from the American College of Physicians state that when a person has no symptoms, the risks of both surgical and nonsurgical treatment for gallstones outweigh the benefits. Experts suggest a wait-and-see approach for such patients, which they have termed expectant management. Exceptions to this policy are those at risk for complications from gallstones, including the following:
- People at risk for gallbladder cancer
- Pima Native Americans
- Patients with stones larger than three centimeters

One study reported that very small gallstones increase the risk for acute pancreatitis, a serious condition. Some experts therefore believe that gallstones smaller than five millimeters warrant immediate surgery.
There are some minor risks with expectant management for asymptomatic or low-risk individuals. Gallstones almost never spontaneously disappear, except sometimes when they are formed under special circumstances, such as pregnancy or sudden weight loss. At some point, then, the stones may cause pain, complications, or both and require treatment. Some studies suggest that the patient's age at diagnosis may be a factor in the possibility of future surgery. The probabilities are as follows:
- 15% likelihood of future surgery at 70 years old
- 20% at 50 years old
- 30% at 30 years old
