隐源性多灶性溃疡性狭窄性小肠炎

Cryptogenic multifocal ulcerous stenosing enteritis

隐源性多灶性溃疡性狭窄性小肠炎（CMUSE）是一种以小肠多部位狭窄和多灶性浅溃疡为特点的小肠疾病，主要的临床表现为慢性或复发性肠梗阻。溃疡一般较浅，位于黏膜层和黏膜下层。纤维性狭窄部位较短（一般1～2cm），相互间隔较紧凑（多为2～10cm），无瘘管形成。外科手术治疗后复发率高，糖皮质激素可有效防止再次手术，多数患者成为激素依赖状态。

Cryptogenetic muhifocal ulcerous stenosing enteritis （CMUSE） is a rare disease, characterized by small intestinal multifocal short stenosis （usually 1 - 2 cm） and superficial ulcers located in the mucosa and submucosa with- out fistula formation. The distance among multifocal stenosis is close （mostly 2 - 10 cm）. High recurrence rate is ex- posesd after surgical treatment, and corticosteroid therapy may prevent recurrent laparotomies but often leads to depend- ence.
