Distal Intestinal Obstruction Syndrome Relieved by Ileoscopy in a Patient With Cystic Fibrosis: A Case Report and Literature Review

Distal intestinal obstruction syndrome (DIOS) is a common complication in patients with cystic fibrosis (CF). Patients typically present with right lower quadrant pain, nausea, abdominal distention, and failure to pass stool or flatus. It can be managed conservatively with medical interventions but some cases may require colonoscopy and even surgery. We report a rare instance in which a CF patient with a previous ileostomy developed DIOS and was successfully managed with ileoscopy after medical management failed.
