Small bowel obstructions (SBOs) are common in patients who have undergone Ileal J-pouch-anal anastomosis (IPAA) surgery. SBO may be caused by stenosis of the diverting ileostomy, volvulus, internal hernia, adhesive bands, anastomotic stricture or intra-abdominal adhesions. Functional outlet obstruction is an important alternative diagnosis to consider in a patient post-IPAA presenting with obstructive symptoms. Recognition of this condition can prevent unnecessary surgery and save the patient from presenting repeatedly with obstructive symptoms.
