I have been hospitalized 17 times for blockages. I have had surgeries for these blockages twice. The first to m e in 2012 . I remain mhm ed symptom free f or approximately 4 years after that surgery. Then they began again. I had the second surgery in October 2017 but have had 3 hospitalizations t ions since then. It's always the same CT scan. NG tube, severe pain which only responds to dilaudid not morphine , versed for the vomiting, I vs , no food and usually a 3 day stay in the hospital. I usually try to get to the nearest and largest medical Center where they have a colorectal surgeon on staff in case they have to do emergency surgery. These attacks have always occurred in the evening. Has anyone been told how to prevent them other than staying on a low residue diet? These attacks have happened when I have been on vacation out of state and in Europe. I am afraid to travel anymore.
