由 消化道出血 Gastrointestinal bleeding, GIB ■消化道出血可以发生在消化道的任何部位。 Gastrointestinal bleeding (GlB)can occur at different locations and different intensities hroughout the intestine ■根据出血的部位将消化道出血分为上消化道(屈氏韧带以上,包括食 管、胃、十二指肠)、中消化道(屈氏韧带至末端回肠之间,包括空 肠及回肠)、下消化道(结肠及直肠)出血。 Gastrointestinal bleeding is subdivided based on the location(upper, lower, middle glB).The upper GI tract comprises the esophagus, stomach, and duodenum(up to the papilla of vateri) Middle GlB relates to that part of the gl tract located below the papilla vateri up to the terminal ileum Lower glb is defined as a bleeding within the colon and rectum. ■胃镜用于诊断上消化道出血,胶囊内镜或小肠镜用于诊断中消化道出 血,结肠镜用于诊断下消化道出血。 Upper glB is diagnosed with esophagogastroduodenoscopy, middle GIB with capsule endoscopy or enteroscopy, and lower glB with colonoscopy.◼ 消化道出血可以发生在消化道的任何部位。Gastrointestinal bleeding (GIB) can occur at different locations and different intensities throughout the intestine. ◼ 根据出血的部位将消化道出血分为上消化道（屈氏韧带以上，包括食 管、胃、十二指肠）、中消化道（屈氏韧带至末端回肠之间，包括空 肠及回肠）、下消化道（结肠及直肠）出血。Gastrointestinal bleeding is subdivided based on the location (upper, lower, middle GIB).
