Exclusion Criteria:
- Patients undergoing surveillance colonoscopy after polypectomy or therapeutic colonoscopy for known polyps
- Patients with a history of colonoscopy within the past 5 years
- Patients with highly suspected or confirmed colorectal cancer

- Pregnant or breastfeeding women
- Patients with gastrointestinal obstruction
- Patients with inflammatory bowel disease, colonic polyposis, or melanosis coli

- Patients currently participating in another clinical trial or who have participated in another clinical trial within the preceding 60 days
- Patients with failed cecal intubation for any reason (e.g., obstructing lesion, intolerance of the procedure)
- Patients with an Aronchick bowel preparation score >3 at colonoscope insertion, indicating inadequate preparation requiring a repeat bowel preparation

Intervention / BehandlingIntervention / Behandling |
|---|---|
|
Eksperimentel: Acetic Acid-Indigo Carmine Chromocolonoscopy Group
|
Participants undergo colonoscopy with acetic acid-indigo carmine chromoendoscopy.
After successful cecal intubation and randomization, the colonoscope is withdrawn and a spray catheter is used to apply an opaque acetic acid-indigo carmine solution from the cecum to the splenic flexure.
|
|
Sham-komparator: Brilliant Blue Chromocolonoscopy Sham-Control Group
|
Participants undergo colonoscopy with brilliant blue dye application as a sham chromoendoscopy control to maintain participant blinding.
After cecal intubation and randomization, an opaque brilliant blue solution is sprayed from the cecum to the splenic flexure using a spray catheter, with suctioning of any excess dye.
