摘要:
【摘要】 目的 探讨恶性胆道梗阻引流前后胆道微生态改变情况,从微生态角度研究胆道梗阻与引流干预对胆汁微生物群的影响。方法 2020年1月至 2022年12月对32例恶性胆道梗阻患者行DSA导引下经皮穿刺置管引流术(PTCD),22 G引流针进入胆道并经造影确认位于肝内胆管内后抽取15~20 mL胆汁,经导丝植入外或内外引流管,7 d后经引流管抽取胆汁。两次胆汁样本送检培养及基因测序。收集整理患者一般资料,包括是否发生急性胆管炎及其严重程度,是否使用过抗生素进行治疗等。结果 32例患者中胆管细胞癌15例,胰腺癌10例,肝细胞癌3例,肝门淋巴结转移瘤(胃肠道恶性肿瘤)4例。引流前胆汁微生物群中伯克霍尔德菌属、不动杆菌属、假单胞菌属和葡萄球菌属相对丰度高,正常胆道内其他微生物种多样性和均匀度均降低。结论 正常胆道系统内存在稳定的微生物群,恶性梗阻胆道微生物群组成与之相似。引流后胆汁内肠属菌群丰度增加,原胆道微生物群落的物种丰度及多样性减少,可解释胆道引流后患者更容易发生胆道感染的临床现象。
