There were limitations to our study. It was a historical cohort study from a tertiary care center. There might have been referral and selection biases, because of the nature of practice of our Subspecialty Pouchitis clinic with a majority of the patients having a variety of pouch disorders. Since multiple adverse pouch complications were measured, the study might have been underpowered with type II error. EGD was performed for a variety of indications at different time points from the IPAA surgery with suspicion for upper GI diseases. It would be desirable to design a larger, prospective study to evaluate the predictive role of pre- and post-operative EGD in consecutive patients.
