"In a patient who has asymptomatic cholelithiasis as an incidental finding, however, there are no data to suggest that any therapeutic intervention is justified. Fewer than 25 percent of patients with asymptomatic cholelithiasis will develop symptoms that require intervention over a 5 year follow-up period."
