上消化道出血在临床上颇为常见,病死率高达8～13.7％。近年来,由于急症内窥镜检查(下称急症镜检)的开展,对出血部位和病因能迅速作出诊断,并可在内窥镜直视下,采取各种止血措施,不仅提高了诊断水平,而且对改善预后、降低病死率、减少输血量等都起到积极的作用。现就急症镜检在上消化道出血中应用的近况作一介绍。 Upper gastrointestinal bleeding in the clinic is quite common, case fatality rate as high as 8 ~ 13.7%. In recent years, due to the emergency endoscopy (hereinafter referred to as acute and microscopic examination) carried out on the bleeding site and cause of the diagnosis can be quickly and under endoscopic direct vision, to take a variety of hemostasis measures, not only improve the diagnostic level , But also play an active role in improving prognosis, reducing mortality and reducing blood transfusion. Now on the application of emergency microscopy in the upper gastrointestinal bleeding for an introduction.
