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.

Treatment

Our Houston team offers a full range of care for backwash ileitis.

Lifestyle and Diet Changes

  • Take small, frequent meals in order to lessen the stress on intestines.
  • Take a low-residue diet during flares to reduce irritation.
  • Bring a lot of water- really, really important in the heat of Houston.
  • Consumption of spicy, greasy, and high-fiber foods that aggravate the symptoms should be avoided.

Medications

  • 5-ASA agents (e.g., mesalamine) to lower the inflammation of the ileum.
  • Rapid symptom-relief intervention(in flare) using short-term corticosteroids.
  • Maintenance therapy (i.e., with immunomodulators e.g., azathioprine)
  • Moderate-to-severe cases Biologic therapy (infliximab, vedolizumab)

Minimally Invasive or High Technology Procedures

  • Endoscopic dilation to deconstriction of focal narrowing of ileum.
  • When medications and dilation are inadequate laparoscopic surgery is used.
  • Perfect biopsy processes to inform specific therapy.
