ABSTRACT: Background
Biliary infections like cholecystitis and cholangitis are common and could be life threatening if treated inappropriate. Prescribing antibiotics is the key to control such infections. Occurrence of bacterial resistance to antibiotics is highly probable and should be continuously monitored. This study aimed to re-evaluate bacterial species distribution and their interaction to antibiotics in biliary infections.Method
Total 2288 patients who were diagnosed as whether acute or chronic cholecystitis with/without concurrent cholangitis enrolled in this cohort study. All were candidate for cholecystectomy operation. In the theatre a sterile bile sample was aspirated from the gallbladder as early as the organ was exposed. Analysis was performed on culture and antibiogram results.Results
Finally 492 (21.5%) microorganism growth was seen in all culture environments. Bacterial colonization was most common in cholangitis (63.8%) which followed by acute (26%) and chronic (10.9%) cholecystitis respectively (p = 0.001). Escherichia coli (58%) and Klebsiella species (12.2%) were mostly isolated pathogens. Antibiogram study illustrated bacterial sensitivity of gram-negative pathogens to imipenem (100%), amikacin (98.1%), and gentamicin (90.4%) which in gram-positive bacterial species was 100% to imipenem, vancomycin, rifampcin, and clindamycin.Conclusion
Cephalosporins as an empirical treatment for biliary infections is not suitable. Aminoglycosides including amikacin and gentamycin are costly beneficial as the first line for empirical antibiotic therapy in selected patients because of their good bacterial sensitivity and low expenses. Imipenem should remain for multidrug resistance species.
