纤维胃镜检查与幽门螺杆菌交叉感染检测报告

对胃镜检查导致幽门螺杆菌（Ｈｐ）交叉感染的可能性进行调查。结果从清洗消毒后胃镜活检吸引管道及活检钳采样培养出Ｈｐ。老年慢性胃炎患者随胃镜检查次数增多，Ｈｐ阳性率增高；Ｈｐ阴性胃炎患者随胃镜随访次数增加，Ｈｐ阳性率增高；Ｈｐ转为阳性随访者的平均年龄大于随机抽查、年龄匹配的正常和慢性胃炎对照中Ｈｐ阳性者。提示，胃镜及附件灭菌不严可成为Ｈｐ交叉感染的一个潜在途径，老年人接受多次胃镜检查可增加感染的危险性

Nosocomial Transmission of Helicobacter pylori through Fiberoptic Gastroscopy

The relationship of nosocomial transmission of Helicobacter pylori (Hp) by fiberoptic gastroseopy was investigated. Hp was cultured from the materials obtained from the suction/biopsy channel (4/12 times) and biopsy forceps (3/10 times). The positive rate of Hp was increased with times of undertaking endoscopy in the past in elder patients with chronic gastritis. The rate from Hp negative transforming into positive also increased with the times of receiving endoscopic follow-up in the past in patients with Hp negative chronic gastritis. The average age of Hp positive patients were older in those patients under follow-up studies than that in randomly age-matched normal or chronic gastritis controls. The results suggested that the contamination of gastroscopic equipment played a potential role as vehicle causing nosocornial infection of Hp, The risks of Hp transmission correlated with times of undertaking endoscopy, especially in the elderly.
