Abstract

Purpose
In general, bile is normally sterile. However, there are reports bactibilia may occur in certain instances, though the causal factors are unclear. We analyzed possible preoperative predictors of bactibilia upon cholecystectomy.
Methods
Bile samples were collected during cholecystectomies from November 2018 to November 2019. A total of 428 open or laparoscopic cholecystectomies were performed. Preoperative, intraoperative, and postoperative variables were compared between the culture-positive and culture-negative groups.
Results
One hundred fifty-seven patients (36.7%) were culture-positive. Gram-negative bacteria (95 [61.0%]) were more common. Escherichia coli (38 [40.0%]) and Enterobacter (22 [23.2%]) were the most common species. In univariate analysis, age of ≥70 years (P < 0.001), male sex (P < 0.001), high American Society of Anesthesiologists physical status grades (P = 0.001), diabetes mellitus (P = 0.002), jaundice (P = 0.007), high Tokyo Guideline grades (P = 0.008), percutaneous transhepatic gallbladder drainage (PTGBD; P < 0.001), endoscopic retrograde cholangiopancreatography (ERCP; P < 0.001) were identified as a risk factors for bactibilia. In multivariate analysis, age of ≥70 years (hazard ratio [HR], 2.874; 95% confidence interval [CI], 1.769–4.670; P = 0.001), ERCP (HR, 9.001; 95% CI, 4.833–16.75; P < 0.001), and PTGBD (HR, 2.866; 95% CI, 1.440–4.901; P = 0.002) were independent risk factors for bactibilia.
Conclusion
Among patients who underwent cholecystectomy, those who were elderly, symptomatic, and underwent preoperative drainage were more likely to have bactibilia. In such cases, surgeons should take care to prevent bile leakage during surgery and consider administering appropriate antibiotics.
