Backgrounds/Aims: Common bile duct stones (CBDS) affect the management of acute cholecystitis (AC). This study aims to investigate the utility of liver function tests (LFTs) in predicting the presence of CBDS in AC patients. Methods: Retrospective cohort study of adult patients with AC found in the American College of Surgeons National Surgical Quality Improvement Program database from 2008 to 2016. Patients were classified into two groups, without CBDS (AC‒) and with CBDS (AC+). LFT results namely total bilirubin, SGOT and ALP were collected and categorized into normal and abnormal with the cut-offs of 1.2 mg/dl for total bilirubin, 40 U/L for SGOT and 120 IU/L for ALP. Measures of diagnostic accuracy for individual and combinations of LFTs were computed. Results: A total of 32,839 patients were included in the study, with 8,801 (26.8%) AC+ and 24,038 (73.2%) AC‒ patients. Their mean age was 52.4 (±18.6) years and over half (59.1%) were females. Mean LFT results were significantly higher in the AC+ group for total bilirubin (1.82 vs 0.97), SGOT (110.9 vs 53.3) and ALP (164.4 vs 102.3) (p＜0.0001). The proportions of abnomal LFTs were significantly higher in the AC+ group for total bilirubin (47.7% vs 20.2%), SGOT (62.8% vs 27.1%) and ALP (56.6% vs 21.0%) (p＜0.0001). Among AC+, the odds of having abnormal results for bilirubin, SGOT and ALP were found to be 3.61, 4.54 and 4.90 times higher than among AC‒, respectively. Conclusions: Abnormal LFTs are strong predictors for the presence of CBDS in patients with AC. Normal LFTs should be interpreted with caution as some patients with AC and CBDS might not present with characteristic abnormalities in results.
