Short Video Colonoscopy (DDEWAN) uses a flexible endoscopic camera to examine the digestive tract directly.
This is a procedure, not a blood test—mucosa is inspected and biopsies may be taken.
Colonoscopy requires bowel preparation the day before—follow instructions strictly.
About endoscopy
What is Short Video Colonoscopy (DDEWAN)?
Direct visualization of the GI tract for ulcers, bleeding, polyps, inflammation, or tumors.
Biopsy specimens go to histopathology separately.
Blood sample?
Routine blood draw is not the main test; IV access may be used for sedation monitoring.
Why is it done?
Persistent pain, bleeding, anemia, reflux, polyp screening, or follow-up of abnormal imaging.
Direct visualization with biopsy can provide definitive diagnosis.

Bowel prep with laxatives and clear liquids the day before.
Inform the team about blood thinners, pregnancy, and heart or lung disease.
Sedation?

Risks?
Perforation and serious bleeding are rare at experienced centers.

Immediate findings at procedure; biopsy results in several days.
Aftercare and follow-up
After the procedure
Rest if sedated; mild throat discomfort for upper GI; avoid heavy meals initially.
Biopsy results?
Histopathology in 5–10 days; polyp findings guide next surveillance interval.
