Capsule Retention Caused By Cryptogenic Multifocal Ulcerous Stenosing Enteritis

Introduction: cryptogenic multifocal ulcerous stenosing enteritis (CMUSE) is a rare illness. Capsule retention (CR) has been reported in a few cases of CMUSE.Methods: we present four cases of CMUSE with CR. None of the patients showed any symptoms or signs of small bowel obstruction before capsule endoscopy (CE). All patients denied a history of non-steroidal anti-inflammatory drugs intake, radiotherapy treatment or abdominal surgery.Results: CE disclosed circumferential stenosis with or without ulcers in the small bowel, some accompanied by mucosal edema, white spots and nodules. All patients underwent an elective surgery to remove the retained capsule and resect the lesions.Conclusion: CE plays a positive role in diagnosing CMUSE. CE findings are as important as CR to alert about the diagnosis of CMUSE.
