Reviewer's report:  
 
This article is a case report about capsule retention in Cryptogenic Multif ocal Ulcerous 
Stenosing Enteritis (CMUSE) patients. This is a rare small bowel disease and difficult to 
diagnosis. But it is important to distinguish from CMUSE to Crohn's disease and intestinal TB 
due to the same presentation of multiple small intestine u lcers and strictures. I have some 
comments about this article.  
 
 
1. Did the patient ever receive MR enterography(MRE) before capsule endoscopy exam? 
Because the MRE has better diagnostic rate in small bowel stricture/narrowing and can 
differentiate from acut e and chronic inflammation related intestine stricture.  
 
 
2. Patency capsule is suggested to identify patients who are at a higher risk for capsule 
retention in the video -capsule study.  
 
 
3. ACT is not a common abbreviation for abdominal computed tomography, you  may use 
abdominal CT instead of ACT.
