My daughter is 28,65 kg. in 1997 was diagnosed with UC. Initially contrlled through medications: asacol, pentasa and ultimately asathioperine.She went through periods of relapses. One year later, she had heart surgery to remove what was initially suspected to be mixoma but turned out to be a blood clot. She was put on clixane injections ever since and was substituted with warfarin later on and still taking it. In 2001 she had pancolectomy surgery which was successful.But a few months later she noticed a blister-like sac in an area in the abdomen where she had one of several tubes to remove body discharge during surgery. When the blister burst she noticed that resulting fluid had a stool smell suggesting existence of a tract extending from the bowel to the surface.And this tract persists up to date. Several tests were carried out and some doctors believe this to be a fistula , a symptom of Chron s, even though my daughter doesn t have any of the other symptoms known to be associated with Crohns. But, every now and then she experiences episodes of watery stool and frequent visit to wc(more than 10 times) against 5-6 times in normal times. Please advise Thanks
