My GI doctor called me tonight to discuss a problem I'm having with a rectal stricture. He said he thinks I need stronger medicine. I'm presently taking Lialda. I don't understand how medicine can have any effect on healing a stricture. He wants to do a colonoscopy to biopsy it again, seeing it's been a year, and the stricture was dilated in June by a surgeon. There wasn't much improvement and I need another dilation. I'm just really confused about why he would want me to take stronger medications to treat it. Anybody?
