Imaging studies to detect common bile duct （CBD） stones were performed in 186 patients, who constituted the study population. Biochemical liver tests before and after surgery, and with the presence or absence of CBD stones were analyzed.RESULTS： In 96 patients with cholelithiasis and cholecystitis without evidence of CBD stones, 49 （51.0%） had an alanine aminotransferase level elevated to 2-3 times the upper limit of normal, and 40 （41.2%） had an elevated aspartate aminotransferase level. Similar manifestations of hepatocellular injury were, as would be expected, even more obvious in the 90 patients with CBD stones. These markers of hepatocellular injury resolved almost completely within 2 wk to 1 mo after cholecystectomy. Compared to 59 patients with histologically less severe cholecystitisin the group undergoing urgent surgery （total 74 patients）, the 15 patients with a gangrenous gallbladder had a higher mean level of total bilirubin （2.14 ± 1.27 mg/dL vs 2.66 ± 2.97 mg/dL, P 〈 0.001） and white cell count （9480 ± 4681/μL vs 12840 ± 5273/μL, P = 0.018）.CONCLUSION： Acute hepatocellular injury in cholelithiasis and cholecystitis without choledocholithiasis is mild and transient. Hyperbilirubinemia and leukocytosis may predict severe inflammatory changes in the gallbladder.展开更多
