Cholestasis is not considered to be cholecystitis, and there is a difference between the two.

Cholecystitis is a series of lesions caused by inflammatory stimulation of the gallbladder due to blockage of the gallbladder wall or stones. Cholecystitis is usually characterized by pain in the right upper abdomen, which is severe, accompanied by fever, nausea and vomiting. Cholecystitis may also present with cholestasis in the early stages, but cholestasis is usually seen in patients who have been fasting for a long time, or who suffer from cholangitis, acute pancreatitis, or tumors in the liver and gallbladder. If cholestasis or cholecystitis occurs, you should consult a doctor in time to clarify the relevant diagnosis, and under the guidance of the doctor to take reasonable medication and active treatment.
