儿童下消化道出血的内镜诊疗思路

Endoscopie diagnosis and treatment of lower gastrointestinal bleeding in children

下消化道出血,通常涉及小肠及结直肠出血,指发生在Trietz韧带以下肠道出血情况。在儿童群体中,下消化道出血的发生率相对较高,相较于上消化道出血,关于下消化道出血的研究较少,缺乏权威性文献和共识。随着近年来儿童内镜技术的迅速发展,特别是小肠镜、胶囊内镜以及内镜下各种治疗方法的应用,大多数下消化道出血患儿均能获得有效的诊断和治疗。然而,仍有少数临床诊治困难。文章将对儿童下消化道出血的临床评估、诊断和治疗方法进行概述,目的是为了标准化儿童下消化道出血的诊疗流程。

Lower gastrointestinal bleeding typically refers to bleeding from the intestines below the Trietz ligament,which includes small intestine bleeding and colon bleeding.It is relatively common in children,and although there is relatively less research on lower gastrointestinal bleeding compared to upper gastrointestinal bleeding,and there are few guiding documents and consensus.With the rapid development of pediatric endoscopy technology in recent years,especially small bowel endoscopy,capsule endoscopy,and various endoscopic treatment methods,most children with lower gastrointestinal bleeding can be effectively diagnosed and treated.However,there are still a few cases that are difficult to diagnose and treat clinically.This article summarizes the clinical evaluation,diagnosis,and treatment methods of pediatric lower gastrointestinal bleeding,aiming to standardize the diagnosis and treatment process of pediatric lower gastrointestinal bleeding.
