Clinical issues facing pouch patients: an introduction to a special issue on the ileal pouch

For over 40 years, restorative proctocolectomy has been used in patients with ulcerative colitis or familial adenomatous polyposis undergoing proctocolectomy. Radiologists are now encountering an increasing number of patients with an ileal pouch and therefore need to understand the clinical issues and concerns in these patients. This review is the introduction of a special issue on the ileal pouch and was written with both surgeon and gastroenterology input. The intent is to assist the radiologist in understanding the clinical questions posed by both the patients and their physicians. Subsequent sessions will address specific imaging modalities and techniques, how the gastroenterologists and surgeons address issues with these patients, and a final session summarizing the sessions and speculating on future investigations and approaches.
