小肠胶囊内镜滞留现状及临床进展

Current status and clinical progress of capsule retention

小肠胶囊内镜检查被越来越广泛应用于不明原因消化道出血、不明原因腹痛等怀疑小肠病变者。胶囊内镜滞留是胶囊内镜检查最常见的并发症,发生率为1%~2%,主要见于克罗恩病、小肠肿瘤等疾病检查中。大部分胶囊内镜滞留患者无任何临床症状,少部分可发生肠梗阻或肠穿孔等严重并发症。胶囊内镜滞留后可采取保守或者内镜下及外科取出的方法。目前临床中用新型的探路胶囊来降低胶囊内镜滞留发生的风险。

Small bowel capsule endoscopy has been now widely applied for patients who are highly suspected of small bowel disease with occult bleeding and unexplained abdominal pain.Capsule retention is a major complication,with an overall incidence of l%-2%,commonly seen in the detection of Crohn's disease and small bowel tumors.Most cases run asymptomatically after retention,while intestinal obstruction or perforation can occur ralely.Conservative methods,endoscopic or surgical interventions are performed to deal with the retention.Patency capsule is currently used as a novel tool to reduce the risk of capsule retention.
