Abstract: Abdominal cocoon （AC） is a rare peritoneal disease related to the autoimmune system. It is usually caused by an abnormal cocoon-shaped fibrous film covering the whole abdomen or part of the small intestine and other organs, causing acute and chronic intestinal obstruction symptom. At present, its etiology and pathogenesis are not completely clear, and the misdiagnosis rate of the first diagnosis is high, which is often accidentally found during surgery. Usually increase related knowledge reserves, carefully read CT before surgery can predict the possibility of AC, keep vigilant and carefully explore during surgery to avoid misdiagnosis and missed diagnosis of AC.

摘要： 腹茧症（AC）是一种罕见的,与自身免疫系统相关的腹膜疾病,通常由一层异常茧状纤维薄膜包裹全腹或部分小肠等脏器而引起急、慢性肠梗阻等症状。目前其病因及发病机制尚未完全清楚,且首诊误诊率高,往往因其他疾病术中偶然发现。平时增加相关知识储备,术前仔细阅读CT可预判AC存在的可能,术中保持警惕并仔细探查,避免AC误诊、漏诊。
