Following two stage CBE, stricture rates without preemptive therapy in noncircumferential, circumferential <2cm, and circumferential <3cm disease, are estimated to be 30%, 50% and 70% respectively. The investigators predict a 50% reduction in stricture rate with oral steroid therapy. With a primary analyses of oral steroid versus placebo tested at a 5% level of significance in a two tailed test, 58 patients are needed per group. Allowing for a 5% drop out rate, a total of 126 patients are required. The study will be performed at five Australian Tertiary Hospitals, and the recruitment period is estimated to be 2 years.
