Distal Intestinal Obstruction Syndrome resolved by dissolution with Coca-Cola® via colonoscopy in a cystic fibrosis patient.

We report the case of a 37 years old woman who presented to emergency department because of a 3 days history of abdominal disconfort and distension. After physical examination and a CT scan of the abdomen she was diagnosed of Distal Intestinal Obstruction Syndrome (DIOS) in the context of her underlying cystic fibrosis. Conservative management was attempted with no improvement. A colonoscopy was performed and thick solid feces were seen filling the cecum and right colon. An attempt to dissolve the impacted stool was made by instilling one liter of Diet Coca-Cola® through the working channel of the colonoscope. After that, the condition of the resolved in the following 24 h with no more interventions.
