紧急内镜检查系指本次上消化道出血后24～48小时内进行的检查。随着内镜的不断更新,紧急内镜检查技术不断提高,其已成为上消化道出血的一种安全重要诊断方法。一、紧急内镜对上消化道出血的病因诊断价值1.紧急内镜检查的时机一般认为距发病时间越近,阳性率越高。由于正常状态下胃粘膜每日更新1/3,如病情不发展,72小时粘膜病变可修复,且不留痕迹。然而,为防止并发症发生,紧急内镜检查的时机仍应根据病情决定,最好在初步处理病情稳定后再行检查,不必过分强调即时检查。国内有报道次日病灶检出率仍达92.3%,故多数主张在24～48小时内进行。
Emergency endoscopy refers to the examination performed within 24 to 48 hours after the upper gastrointestinal bleeding. With the continuous update of endoscopy, emergency endoscopy continues to improve, which has become a safe and important diagnostic method for upper gastrointestinal bleeding. First, the emergency endoscopy on the etiology of upper gastrointestinal bleeding diagnostic value 1. The timing of emergency endoscopy is generally believed that the closer the time of onset, the higher the positive rate. Due to the normal state of the gastric mucosa updated daily 1/3, if the disease does not develop, 72 hours mucosal lesions can be repaired, and without leaving any traces. However, in order to prevent the occurrence of complications, the timing of emergency endoscopy should be decided according to the condition. It is better to conduct the examination after the initial treatment of stable condition, without having to overemphasize the immediate examination. Domestic reports the next day the detection rate is still up 92.3% lesions, so the majority of claims within 24 to 48 hours.
