Liver function abnormalities in postoperative gallstone patients need to be analyzed according to the abnormalities in the patient’s liver function. If the postoperative ALT elevation does not exceed two times the normal value, observation and treatment can be carried out; if the ALT value is higher than two times the normal value, hepatoprotective treatment is needed. 1. Liver function abnormality mainly depends on the alanine aminotransferase index, postoperative gallstone patients with alanine aminotransferase value not more than 2 times the normal value of the rise is usually considered to be postoperative stress caused by alanine aminotransferase value abnormalities, you can not deal with it for the time being, and regular review of biochemistry to find out whether the value of alanine aminotransferase is back to normal. 2. For gallstones after surgery, the value of alanine aminotransferase increased more than 2 times patients, need to carry out liver protection treatment, usually choose glutathione, glycyrrhizic acid for liver protection treatment, but need to be used under the guidance of the doctor to identify the evidence, after 1 to 2 weeks of treatment, alanine aminotransferase value back to normal. Postoperative patients with gallstones, if there is any discomfort, promptly inform the situation to the doctor on duty, do not be careless, so as not to delay treatment.
