Accuracy	Precise lower colon assessment
Interpretation	Identifies abnormalities or diseases

Flexible sigmoidoscopy: A quick, accurate procedure to visualize the lower colon, identifying abnormalities or crohn's disease diagnosis, with high accuracy.

5. Upper Endoscopy

Direct examination of the upper digestive tract, including the esophagus, stomach, and duodenum.
Biopsy collection for further analysis and identification of abnormalities.
Detection of inflammation, ulcers, strictures, or other signs of Crohn's Disease in the upper gastrointestinal tract.

Upper Endoscopy	Details
Also Known As	Upper Gastrointestinal Endoscopy
Purpose	Examine the esophagus, stomach, and duodenum for abnormalities
Sample	N/A

Result Value	Visual examination & potential biopsy results
Normal Value	No abnormalities/ signs of Crohn's Disease
Accuracy	Accurate upper GI inspection
Interpretation	Interpretation is done by a healthcare professional based on visual findings and biopsy results

Upper endoscopy, or upper gastrointestinal endoscopy, examines the upper digestive tract for abnormalities, including signs of Crohn's Disease, using a flexible tube with a camera. It provides visual examination and biopsy results, aiding accuratecrohn's disease diagnosis.

6. Capsule Endoscopy

Uses a small camera capsule swallowed by the patient to capture images of the digestive tract.
Provides detailed visualization of the small intestine.
Aids in identifying small bowel inflammation, ulcers, bleeding, and other abnormalities associated with Crohn's Disease.

Capsule Endoscopy	Details
Also Known As	Small bowel visualization
Purpose	Visualize small bowel

Blood tests, stool tests, and colonoscopy are diagnostic procedures used to detect inflammation and abnormalities in Crohn's disease diagnosis.

Crohn's Disease Differential Diagnosis

Similar Diseases	Differentiating Factors
Ulcerative Colitis	Inflammation is limited to the colon.
Irritable Bowel Syndrome	Absence of structural abnormalities.
Celiac Disease	Gluten sensitivity and small intestine involvement.
Infectious Colitis	Infection-related symptoms and history of exposure.
Diverticulitis	Presence of diverticula in the colon.

Crohn's disease diagnosis can be differentiated from similar diseases like ulcerative colitis, irritable bowel syndrome, celiac disease, infectious colitis, and diverticulitis based on specific distinguishing factors.
