Barium Enema – Colon Study: Complete Guide
Introduction:
A Barium Enema is a radiological procedure used to visualize the large intestine (colon). By introducing barium sulfate contrast into the rectum, X-rays or fluoroscopy can assess the structure, movement, and detect abnormalities in the colon.
Indications for Barium Enema
-
Chronic constipation or difficulty in passing stool
-
Bleeding per rectum
-
Suspected polyps, tumors, or strictures
-
Diverticulosis or inflammatory bowel disease (IBD)
-
Evaluation of unexplained abdominal pain
Preparation for the Procedure
-
Dietary Restrictions:
-
Follow a clear liquid diet 24 hours before the test
-
-
Bowel Cleansing:
-
Laxatives or enemas may be prescribed to empty the colon
-
-
Clothing:

-
Procedure Steps
-
Patient Positioning: The patient usually lies on their side or back on the X-ray table.
-
Contrast Administration:
-
Barium sulfate is introduced into the rectum via a flexible tube.
-
Sometimes air is added to create a double-contrast study, giving better visualization.
-
-
Imaging:
-
Multiple X-ray images or fluoroscopic views are taken as barium fills the colon.
-
Helps detect strictures, polyps, tumors, diverticula, or motility disorders.
-
-
Completion: Barium is drained, and the patient is allowed to clean up.
Post-Procedure Care
-
Expect white-colored stool for 1–2 days
-
Mild cramping or bloating is normal
-
Drink plenty of water to clear the barium
-
Contact the doctor if there is severe pain, vomiting, or inability to pass stool
Advantages of Barium Enema
-
Non-invasive and highly diagnostic
-
Detects structural and functional abnormalities
-
Useful for screening and pre-surgical evaluation
Conclusion:
A Barium Enema is a safe and effective procedure to evaluate the colon. Proper preparation, technique, and post-care are essential for accurate diagnosis and patient comfort.
