本文讨论激光在纤维光学内窥镜中的应用及其作用。纤维光学内窥镜检查十年来,使用纤维光学内窥镜诊断胃肠和呼吸道疾病越来越广泛。目前,内窥镜不但用于诊断而且用于治疗(Katon,1976),尤其用于十二指肠镜检查胆石取出术和结肠镜检查息肉切除术(Cotton和William,1980),同时也使用于急性胃肠道出血的患者。如果这样的患者在入院后重新出血,不管其原因如何都是危险的(Johnston等,1973)。对一些病人来说,出血是不治之症的最后症状,而对另一些如胃癌或食道静脉曲张的病人来说,即使出血得到控制,但也预示了不祥之兆。所以,出血性消化道溃疡是有待于临床解
This article discusses the use of laser in fiber optic endoscopy and its role. Fiber optic endoscopy 10 years, the use of fiber optic endoscopy diagnosis of gastrointestinal and respiratory diseases is more and more widespread. Currently, endoscopes are used not only for diagnosis but also for treatment (Katon, 1976), especially for duodenal gland gallstone removal and colonoscopy polypectomy (Cotton and William, 1980) Acute gastrointestinal bleeding in patients.
