What Is Backwash Ileitis?
Backwash ileitis Backwash ileitis is the inflammation of the terminal ileum in individuals with ulcerative colitis in which the contents of the colon move backwards and damage the small intestine. It is not as severe as Crohn’s disease and yet needs to be managed.
Common Causes and Risk Factors
- Extensive ulcerative colitis (pancolitis)
- Ulcerative colitis duration over 8 years
- Complications such as toxic megacolon
- History of smoking
- Alterations in gut microbiota
Signs and Symptoms
- Cramping pain in the lower right abdomen
- Loose stools or persistent diarrhea
- Urgent or frequent bowel movements
- Mild weight loss and fatigue
- Occasional low-grade fever
How Dr. Rishi Diagnoses Backwash Ileitis?
Dr. Rishi uses a step-by-step approach:
Medical History and Physical Exam
He examines your history of ulcerative colitis, patterns of symptoms (cramps, diarrhea, urgency), past treatment and risk factors including the previous disease history and previous complications of the colon.
Blood Tests
We test inflammatory parameters (CRP, ESR), complete blood count and exclude infections or other factors that can contribute to ileal irritation.
Endoscopic Evaluation
- Colonoscopy with terminal ileum intubation to visually assess inflammation.
- Biopsy of the ileal mucosa to confirm backwash ileitis and differentiate from Crohn's disease.
Imaging Studies
- MRI or CT enterography to rule out strictures, transmural disease or other complications.
Advanced Testing (if needed)
In rare cases, the refinement of the diagnosis or the exclusion of conditions of interest may be done by a capsule endoscopy or specialized microbiome.
Frequently Asked Questions
What is backwash ileitis?
It is inflammation of the terminal ileum as a result of colon contents back washing in that part in individuals with ulcerative colitis.
How common is it?
Backwash ileitis transpires in an estimate of 10-20% of patients with extensive (pancolitis) ulcerative colitis.
What is the difference between it and Crohn disease?
Backwash ileitis is restricted to the distal ileum and is usually milder, whereas Crohn has the potential to attack any GI tract, give patchy lesions, and result in deep ulcers.
Can food changes help?
Yes. The anti-inflammatory diet and small and frequent meals can minimise irritation and enhance the symptoms as it is low-residue.
What medicines are used?
It can be treated with 5-ASA drugs (e.g.; mesalamine), short course steroids, immunomodulators (like azathioprine), or biologic therapy (infliximab or vedolizumab).
Is surgery needed?
Surgical intervention is not common and only done in the instance of complications like strictures or non-respondent cases of surgery to medical treatment.
How fast does treatment work?
It takes some weeks before many patients experience relief of symptoms, but long term medication may be necessary to sustain remission.
