An investigation was made for problems involved in identification of bleeding sites and the incidences of bleeding from esophageal and gastric varices in emergency endoscopy within 24 hr after overt gastrointestinal bleeding. Varices or ulcers are not always the source of bleeding, and endoscopic examinations should be performed early after the onset of bleeding to make correct identification of the bleeding site. For such purposes, aspiration using endoscopy, washing under direct observation using a teflon tube and changing of body posture were found effective. During the 6 years from 1977, bleeding from the esophageal or gastric varices was detected in 4 cases out of 30 cases of esophageal or gastric varices which had undergone emergency endoscopy for overt bleeding. After June, 1979, when hemostatic measure using pure ethanol was applied actively, bleeding from esophageal or gastric varices was observed in 4 cases (2.5%) out of 160 cases. Results of the present emergency endoscopy revealed that the incidence of rupture of varices was not so high as had been expected conventionally.
对显性胃肠道出血后24小时内急诊内镜检查中涉及的出血部位识别问题以及食管和胃静脉曲张出血的发生率进行了调查。静脉曲张或溃疡并不总是出血的来源，出血发生后应尽早进行内镜检查，以正确识别出血部位。为此，发现内镜抽吸、使用聚四氟乙烯管在直视下冲洗以及改变体位是有效的。在1977年以来的6年中，30例因显性出血接受急诊内镜检查的食管或胃静脉曲张患者中，有4例检测到食管或胃静脉曲张出血。1979年6月以后，当积极应用纯乙醇止血措施时，160例中有4例（2.5%）观察到食管或胃静脉曲张出血。本次急诊内镜检查结果显示，静脉曲张破裂的发生率并不像传统预期的那么高。
