For the treatment of cholesterol crystals, surgery or medication can be given according to the situation, as follows: 1. Surgery: if the diameter of the crystals is larger than 3cm, laparoscopic cholecystectomy should be preferred. 2. Medication: if the diameter of the crystals is smaller than 3cm and there are no obvious clinical symptoms, we can consider applying the medication of stone-exclusion and lithification for treatment. Among the traditional Chinese medicines, there is Da Chai Hu Tang, and among the western medicines, Ursodeoxycholic Acid can be taken orally, but the course of treatment is usually longer, usually in 6-24 months. The majority of cholesterol crystals are located in the gallbladder and are yellow or yellow-gray in color, varying in shape and size from as small as fine sand to as large as several centimeters in diameter. Cholesterol crystals are usually hard, mostly smooth and round or oval in shape. Once cholesterol crystals are not treated systematically and in a timely manner, cholesterol stones can easily form.
