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 1%-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.
小肠胶囊内镜现已广泛应用于高度怀疑患有隐匿性出血和不明原因腹痛的小肠疾病患者。胶囊滞留是一种主要并发症，总体发生率为1%-2%，常见于克罗恩病和小肠肿瘤的检测中。大多数病例在滞留后无症状，而肠梗阻或穿孔很少发生。采用保守方法、内镜或手术干预来处理滞留情况。通畅胶囊目前作为一种新型工具用于降低胶囊滞留风险。
