在良、恶性胆道狭窄的患者中胆汁细菌培养的阳性率分别为100%和33～36%,以大肠杆菌最为常见,阳性率约为40～48%。术中,如胆汁内存在细菌则更易引起菌血症,所以在梗阻性黄疸的手术中,常常选用头孢菌素和氨基糖甙类抗菌素作为预防。但是这些抗菌素对粪链球菌无明显疗效。本文对胆道粪链球菌菌血症患者应用预防性抗菌素的选择作了研究。全组14例患者的平均年龄为56.1岁(24～71岁),良、恶性梗阻者分别为5例和9例。所有患者术前、后每天取引流管内胆汁作培养,术中均作胆汁 The positive rates of bile bacteria culture in patients with benign and malignant biliary strictures were 100% and 33-36%, respectively. Escherichia coli was the most common and the positive rate was about 40-48%. Intraoperative, such as the presence of bile bacteria are more likely to cause bacteremia, so in obstructive jaundice surgery, cephalosporins and aminoglycoside antibiotics are often used as a preventive. However, these antibiotics have no significant effect on Streptococcus faecalis. In this paper, the choice of prophylactic antibiotics in patients with biliary feces streptococcal bacteremia was studied. The average age of all 14 patients was 56.1 years (range, 24 to 71 years), with benign and malignant obstruction of 5 and 9, respectively. All patients were preoperative and postoperative day to take drainage tube bile for culture, intraoperative as bile
