磁控胶囊内镜在儿童再发性腹痛中的诊断价值

Application of magnetically controlled capsule endoscopy in children with recurrent abdominal pain

目的探讨磁控胶囊内镜在儿童再发性腹痛(RAP)中的应用价值。方法回顾性分析2021年1月-2021年6月上海交通大学医学院附属儿童医院内镜中心125例行磁控胶囊内镜检查的RAP患儿的临床资料,分析镜下病变检出情况和胶囊内镜在消化道各部位运行时间等。结果125例患者中,35例拟行全小肠检查(1例因吞服失败而未完成),90例在磁控条件下行食管及胃部检查。磁控胶囊内镜在食管内的中位运行时间为8.5 (5.3,12.5) s,在胃内的中位运行时间为49.0 (17.7,94.0) min,行全小肠检查的患儿,胶囊内镜在小肠内的中位运行时间为252.0 (192.5,340.0) min,全小肠检查完成率为97.1%(34/35),检查完成后所有胶囊内镜均顺利排出体外。上消化道病变检出率为71.8%(89/124),小肠病变检出率为68.6%(24/35)。磁控胶囊内镜对儿童RAP的总体病变检出率为73.4%(91/124)。结论磁控胶囊内镜在RAP患儿胃肠道病变检查中有较高的病变检出率,且安全无痛苦,具有一定的临床应用价值。

Objective To investigate the clinical applicability of magnetically controlled capsule endoscopy for recurrent abdominal pain(RAP) in children. Methods Children with RAP who underwent magnetically controlled capsule endoscopy from January 2021 to June 2021 were retrospectively enrolled. The detection of endoscopic lesions and the running time of capsules in various parts of digestive tract were analyzed. Results Among the 125 patients, 35 underwent total small intestine examination, one of whom was incomplete because of swallow failure, and 90 underwent esophageal and stomach examination under magnetic control. The endoscopy capsule transited the esophagus, stomach, and small intestine in an median time of 8.5(5.3, 12.5) s, 49.0(17.7, 94.0) min, and 252(192.5, 340.0) min, respectively. The completion rate for the visualization of the entire small bowel was 97.1%(34/35). The capsules were naturally excreted by all patients. The detection rates for gastroesophageal lesions and small intestinal by magnetically controlled capsule endoscopy were 71.8%(89/124) and 68.6%(24/35), respectively. The diagnostic rate for magnetically controlled capsule endoscopy for RAP was 73.4%(91/124). Conclusion Magnetic capsule endoscopy has a high detection rate of gastrointestinal lesions in children with recurrent abdominal pain, and it is safe and painless, which has certain clinical application value.
