title: Pouchogram: predictor of clinical outcome following ileal pouch-anal anastomosis.
abstract: Among 914 patients undergoing ileal pouch-anal anastomosis (IPAA) between January 1981 and June 1989, 463 (51 percent) had a pouchogram (meglumine diatrizoate [Gastrografin; E.R. Squibb & Sons, Inc., Princeton, NJ] enema) to assess anastomosis and ileal pouch integrity before closure of the ileostomy. The aim was to determine whether a pouchogram was useful in predicting clinical outcome.
  
  
  RESULTS
  Abnormal findings were present in 74 patients (16 percent). These included anastomotic and pouch leaks and anstomotic strictures. Pouchograms were normal in the remaining 389 patients (84 percent). The incidence of significant anastomotic stricturing requiring dilatation under anesthesia was much higher in the abnormal than in the normal pouchogram group (33 percent vs. 4 percent, respectively; P less than 0.001). More significantly, an abnormal pouchogram was associated with an overall long-term failure rate of 23 percent, compared with 6 percent for a normal pouchogram (P less than 0.001).
  
  
  CONCLUSIONS
  Abnormal findings in a pouchogram prior to ileostomy closure indicated those patients at high risk of long-term complications following IPAA.
