Abstract:
ObjectiveTo analysis the different types of bacteria in patients with a varying severity of acute cholangitis.Methods241 patients who presented with actue cholangitis between Jan 2008 to Oct 2011 to our hospital were retrospectively studied.These patients were divided into three groups according to the Tokyo Guideline.The bile specimens were obtained intraoperatively.The parameters were compared by SPSS 16.0 package program for statistical analysis.Results75.1 percent of the patients were positive for bacteria in the bile.There were 241 strains of bacterium which included 139 Gram-positive bacteria,99 Gram-negative bacteria and 6 strains of microzyme.Escherichia coli,Enterococcus faecalis,Enterococcus casseliflavus,Pseudomonas aeruginosa and Klebsiella species were the most frequently isolated bacteria.The positive rates for bacteria were significantly different between patients with mild and severe cholangitis (P＜0.05).There was no significant difference between patients with moderate and mild cholangits (P=0.141),or moderate and severe cholangitis (P=0.647).Gram-negative bacteria were more common than Gram- positive bacteria in patients with moderate and severe acute cholangitis (P＜0.05).In patients with moderate and severe acute cholangitis,there was more patients with multiple and mixed bacterial infection.ConclusionsEscherichia coli and Enterococcus species were more common in patients with acute cholangitis.The positive rate of bacteria in the bile in severe acute cholangitis was higher than that in mild acute cholangitis.In patients with moderate and severe cholangitis,Gram-negative bacterial infections and multiple and mixed bacterial infections were more common.
