Overall, enteroclysis is reserved for complicated cases. This imaging modality is roughly as accurate as SBFT and has a shorter examination time; however, the peroral SBFT examination uses less total room time, radiologist time, and radiation, and it has greater patient tolerability. [65]

A useful adjunct study to the initial SBFT or enteroclysis is the peroral pneumocolon evaluation, in which air is instilled per rectum after the opacification of the terminal ileum. [65] This double-contrast examination allows assessment of the distal small bowel or ascending colon or both and often yields improved mucosal detail and greater distention of the terminal ileum.
