245例胆汁细菌培养的临床意义

Analysis of Bile Bacteria Culture in 245 Patients and Its Clinical Significance

目的分析胆道感染患者胆汁细菌培养的临床意义。方法采集245例因急慢性胆道感染行胆囊切除加胆总管切开T管引流术患者的胆汁,进行细菌培养加药敏试验。结果 老年组胆汁细菌培养阳性率显著高于非老年组;患胆总管结石者胆汁细菌培养阳性率显著高于无胆总管结石者。老年组胆汁中最常见的细菌为大肠杆菌。结论年龄及有无胆总管结石对胆汁细菌培养有重要影响。

To analyse the bile bacteria culture of patients with biliary infection and study its clinical significance. Methods We collected bile from 245 patients with acute and chronic biliary tract infection receiving cholecystectomy + choledochotomy + T tube drainage and performed bacteria cultures and drug sensitivity tests. Results The positive rate of bile bacteria culture was significantly higher in elder patients then others. Patients with common bile duct stones had a significantly higher positive culture rate than those without common bile duct stones. Escherichia coli was the most commonly isolated bacteria in elder patients. Conclusion Age and exstence of common bile duct stones had an important influence in the positive rate of bile bactaria culture.
