Objective: To compare the adenomatous polyp detection rate in colonoscopy with double forward-view examination and conventional single forward-view examination of the right colon in adult patients. Colorectal cancer is one of the leading causes of morbidity and mortality worldwide. Colonoscopy is the standard tool for the detection of premalignant lesions, although its performance is lower in the right colon due to the difficulty in visualizing flat and small lesions. Methods: A prospective, comparative, randomized clinical trial conducted at a tertiary-care referral center. Adult patients scheduled for elective colonoscopy were included and randomly assigned to conventional colonoscopy (control group) or double forwardview examination. Demographic variables, bowel preparation quality, procedure time, and polyp detection were analyzed. Results: Thirty-four patients were evaluated (23 in the control group and 11 in the double forward-view examination group). The mean age was 55.3 years, and 56% were women. The quality of bowel preparation was adequate in all included cases. No adenomatous polyps were detected in the right colon in either group. The overall procedure time was longer in the double forward-view examination group. No complications occurred. Conclusions: Double forward-view examination of the right colon did not demonstrate significant differences in adenomatous polyp detection compared to the conventional technique, although it remained a safe procedure. Studies with larger sample sizes are required to evaluate its real impact on clinical practice.
