Entercolysis

Entercolysis is an examination of the small bowel using two separate types of contrast. The first contrast is barium, commonly used in imaging of the GI system. The second is methylcellulose (also known as Citrucel).

This test may aid in the diagnosis of less obvious pathology of the small bowel or motility problems.

How do I prepare for the exam?

You should have already undergone an upper GI study and small bowel study with barium.

You may have a clear liquid lunch and dinner the day before the exam. You will use a bowel prep kit the evening before the exam.

Do not eat or drink anything after midnight the night before the exam.

What can I expect during the exam?

This exam is conducted by a Radiologic Technologist and a Radiologist.

A naso-gastric (NG) tube will be placed into the first part of the small bowel, known as the duodenum. Once successful placement is verified using fluoro (live x-rays), barium will be inserted through the tube.

Methylcelluose will be inserted next, and the technologist will watch on the monitor until the contrast has reached the end of the small bowel.

Images will be taken by the fluoro camera during this time. The NG tube will be removed once all contrast is used and at the end of the small bowel.

The exam will take 1 to 2.5 hours.

What can I expect after the exam?

Unless your physician tells you otherwise, you may resume your normal activities after your exam.

It is normal to loose stools until the methylcellulose has been completely emptied from the system.
