My husband went to the Emergency Room beginning of November with severe pain. After Ultrasound and Xray was thought to have had a bowel obstruction and colitis. Took 2 enemas and 1 suppository to give him relief. We were sent to GI Dr for more tests (colonoscopy and scope down through throat. He had a MR Enterography a couple of weeks ago. Thought Crohn's, thought Colitis. Not sure. What does a mildly enlarged periportal lymph node measuring 18 x 13 mm mean? Next Colon surgeon wants to do a barium enema. Is this proper procedure to find out what is wrong?
