Abstract

Aim: To investigate the efficacy of cap-fitted colonoscopy (CFC) with regard to cecal intubation time.

Methods: Two hundred and ninety-five patients undergoing screening colonoscopy at Gospel Hospital, Kosin University College of Medicine were enrolled in this randomized controlled trial between January and December 2010. Colonoscopies were conducted by a single endoscopist. Patient characteristics including age, sex, body mass index, history of abdominal surgery, quality of preparation, and the presence of diverticulosis were recorded.

Results: One hundred and fifty patients were allocated into a CFC group and 145 into a non-CFC (NCF) group. Cecal intubations were achieved in all patients. Cecal intubation time in the CFC group was significantly shorter than in the NCF group for specific conditions: age ≥ 60 years, prior abdominal surgery, and poor bowel preparation. The number of detected adenomas was higher in the CFC group than in the NCF group (P = 0.040).

Conclusion: CFC facilitated shortening of the cecal intubation time in difficult cases, and was more sensitive for detecting adenomas than was NCF.

Advantage of cap-fitted colonoscopy for preventing red-out. A: Although the precise direction could not be judged, colonoscopy showed a slight fold (white arrows) without red-out; B: A subtle movement showed a dark area at the 11 o’clock position (white arrow); C: Following the dark are at the 11 o’clock position enabled the colonoscopist to find the direction of insertion (black arrows).

Figure 2
Advantage of cap-fitted colonoscopy for observing lateral side. A: The colonoscopist easily noticed the route of insertion because the transparent cap showed the small dark lumen at the 1 o’clock position through its lateral wall (black arrows); B: Following the route shown through the lateral wall of the transparent cap, a wide lumen was found easily.

The opposite, blind side of the folds could be observed with fewer problems during colonoscopy. A: Compressing the tip of a fold straightened the entire fold and improved the view; B: Bending the tip of the endoscope allowed a front view of the lesion at the blind side of the fold.
