Neile,
I finish radiation in Feb 04, dilitations starting in June 04 and hyperberic o2 in august 04. I had 29 treatments, 6 days per week. About a month later, my GI doc said the strictures were gone. I had a couple more dilitations and was ok for 14 months. I never was able to swallow anything until Jan 05 after starting the shaker exercises. I had another dilitation in Jan of this year and will probably need them every year or when things start to get stuck.
