Hello, in 2004-2005 I took the acne medication, accutane. Recently I found out it was causing bowel problems, my problems came about as minor and then increased by 2006 to the point where I didn't pass any stools for upto three weeks. A biopsy was done and my surgeon said my colon was dead. A week ?ater my colon was removed and I was diagnosed with colonic dysmotility. Two questions what causes colonic dysmotility, could it have been theb accutane and was my surgeon allowed to remove my intestine without a cause to follow
