Complications of the Ileal Pouch: Is the Pouchogram a Useful Predictor?

A series of ileal pouchograms from 25 consecutive patients has been analysed retrospectively. Ileal pouchography may demonstrate abnormalities which delay closure of the covering ileostomy. The aim was to determine whether disruption of the ileoanal anastomosis and/or leak at pouchography correlated with pelvic sepsis after ileostomy closure. Disruption of the stapled ileoanal anastomosis is a sensitive (88%) but not specific predictor (57%) for subsequent pelvic sepsis. The predictive value of a negative test is high (89%). Leak of contrast from the anastomosis is specific (81%) but not sensitive (56%) for pelvic sepsis. No significant relationship was demonstrated between width of the presacral space and the presence of pelvic sepsis. No significant relationship was demonstrated between diameter of the ileoanal anastomosis and symptoms of stricture. The presence of anastomotic disruption or leak at pouchography prior to ileostomy closure are useful predictors of potential pelvic sepsis.
