Feasibility study of minimal prepared hydroflush screening colonoscopy

Area of Science:

• Gastroenterology
• Endoscopy
• Colorectal Cancer Screening

Background:

• Screening colonoscopy is vital for early colorectal cancer (CRC) detection, yet low screening rates persist.
• Poor tolerability of traditional bowel preparations is a significant barrier, leading to non-compliance and reduced polyp detection.

Purpose of the Study:

• To evaluate the feasibility, safety, and outcomes of a novel intra-procedural hydroflush technique.
• To assess this technique as an alternative to traditional bowel preparation for CRC screening.

Main Methods:

• A prospective feasibility study involving a minimally prepared intra-procedural hydroflush technique.
• Utilized water-jet pumps and a mechanical suction device following minimal diet restriction, laxatives, and enemas.
• Assessed colon cleanliness using the Boston Bowel Preparation Scale in nine healthy individuals.

Main Results:

• 100% of procedures achieved complete colonoscopy to the cecum.
• Mean cecal intubation time was 5.78 minutes, and mean withdrawal time was 15.33 minutes.
• Adequate visualization was achieved in all cases, with four polyps detected and removed; mild mucosal erosions were noted.

Conclusions:

• Minimally prepared colonoscopy with intra-procedural hydroflush is feasible for colorectal cancer screening.
• Water exchange technology effectively compensates for mild scope stiffness.
• This innovative technique shows potential to enhance patient compliance for CRC screening.
