[Restorative proctocolectomy. A morphological-functional study by computed tomography with coronal scans].
Restorative proctocolectomy with ileal pouch has become the surgical treatment of choice for patients with ulcerative colitis and familial polyposis of the colon. Defecography is the radiologic technique commonly used to obtain detailed information on function and morphology of the ileal pouch, but it fails to depict the pelvis. Computed Tomography (CT), with coronal images only was used to examine 10 patients with ulcerative colitis, submitted to restorative proctocolectomy. Coronal CT, yielding a panoramic view of the pelvis, represent an effective alternative technique to defecography. In fact, the two techniques provide comparable information relative to the ileal pouch; coronal CT also depicts the possible thickening of pouch walls and of pelvic fat tissue. Coronal CT also depicts the continence of ileo-anal and ileo-ileal anastomoses and the functional changes of the perineal muscles at rest and during squeezing. Coronal CT images allow easy and clear detection of such major postoperative complications as pelvic inflammation and fistulae (less frequently stenosis or dehiscences of the anastomosis).
