Hi I have had slowvtransit constipation for many years until my large bowel and colon slowed to a stop. I had an iliostomy in April 2016 with a view to reversing. Now I have terrible trouble with mucus dripping out bum without warning and stomach pain. I now am booked in for collectomy to have large bowel and colon removed and end iliostomy done. This will be permanent. Has anyone had this done and if rectum not removed will mucas still be a problem. My surgeon says mucas will still be around if rectum stays and I can have rectum taken out later on. ???
