Evaluation of preoperative liver function test efficacy in patients with symptomatic cholelithiasis

AIM: The present study aimed at investigating the necessity of preoperative liver function tests (LFTs) in patients with uncomplicated gallstone disease before laparoscopic cholecystectomy. BACKGROUND: Significant relationship between common bile duct (CBD) stones and acute cholecystitis is reported. There are contradictory reports about the effect of CBD stones on liver function tests in patients (LFTs). METHODS: In the current study, patients with symptomatic cholelithiasis who referred to hospitals during January 2015 and May 2016 were enrolled. Routine tests and ultrasonography were performed on all patients before surgery. Data were presented as means ± SD and qualitative variables as frequency (percentage) were considered. Statistical analyzes were performed with SPSS software. RESULTS: A consecutive series of 270 patients (58 males and 212 females) who referred for laparoscopic cholecystectomy were enrolled in this retrospective study. Pre- operative LFTs were normal in 249 patients (85%) and abnormal LFT was detected in 41 patients (15 %). CONCLUSION: This study showed that 15 % of patients with cholelithiasis without dilated CBD had impaired LFTs. Routine LFTs in preoperative evaluation of symptomatic cholelithiasis usually reveals normal findings and is not helpful in uncomplicated cholelithiasis.
