Study Details

Brief summary:

Although Crohn's disease and ulcerative colitis are the main subtypes of inflammatory bowel disease, they differ substantially in disease behavior, prognosis, and treatment paradigm. However, making an accurate diagnosis of Crohn's disease versus ulcerative colitis and assessing disease activity beyond the level of mucosal inflammation remain challenging with contemporary modalities. The objective of the study is to determine the novel role of endoscopic ultrasound in A) differentiating Crohn's colitis versus ulcerative colitis and B) monitoring disease activity in these patients.

Eligibility Criteria

Sex: All

Age: 18 - 70+

Healthy Volunteers: Accepted

Inclusion Criteria:

  • Adults patients ≥ 18 years of age with CD with at least colonic involvement, UC, or non-IBD controls who have been referred for colonoscopy for clinical reasons. The clinical reasons may include colorectal cancer screening, surveillance, diagnostic for CD or UC flare, or gastrointestinal symptoms.

Exclusion Criteria:

  • Pregnant patients.
  • Patients with known current colorectal cancer, infectious colitis, diverticulitis, or microscopic colitis.
  • Patients who have undergone surgery involving the cecum or rectum.

Interventions and Outcome Measures

Arms

experimental: Crohn's Disease

20 patients with Crohn's disease with at least colonic involvement will undergo endoscopic ultrasound assessment of the thickness of wall layers (mucosa, submucosa, muscularis propria, total wall) at the rectum and cecum region during their standard-of-care colonoscopy.

experimental: Ulcerative Colitis

20 patients with ulcerative colitis will undergo endoscopic ultrasound assessment of the thickness of wall layers (mucosa, submucosa, muscularis propria, total wall) at the rectum and cecum region during their standard-of-care colonoscopy.

experimental: Non-IBD Controls

20 patients without inflammatory bowel disease (controls) will undergo endoscopic ultrasound assessment of the thickness of wall layers (mucosa, submucosa, muscularis propria, total wall) at the rectum and cecum region during their standard-of-care colonoscopy.

Interventions

Endoscopic ultrasound catheter (UM-2R/3R, Olympus)

A miniprobe ultrasound catheter (UM-2R/3R, Olympus) will be passed into the colonoscope's accessory channel at the time of colonoscopy to measure the thickness of the different colon wall layers (mucosa, submucosa, muscular propria, and total wall thickness) in the cecum and rectum.

Primary outcome measure

  • Active Crohn's disease has significantly thicker submucosa layer compared to patients with active ulcerative colitis and non-inflammatory bowel disease controls. [ Time Frame: Day 1 ]
