Abstract Background Colorectal cancer (CRC) is one of the most common cancers worldwide. Most CRCs develop from malignant potential polyps, especially adenomas, SSPs and SSLs. Screening is associated with a reduction in CRC incidence through the detection and removal of precancerous polyps and with reduction in CRC related death through reduction of the incidence and early detection of CRC. Colonoscopy is the most widely used screening tool. Unfortunately during colonoscopy examinations, a substantial number of polyps are still being missed. These missed polyps though to be at least 50% of interval CRCs. Objective comparison between G-EYE colonoscopy and standard colonoscopy (SC) for increasing adenoma/polyp detection rate. Patients and Methods prospective randomized study was conducted on 80 Patients as one group, selection done at Hepatology and Gastroenterology department in Theodor Bilharz Research Institute and Outpatient clinic of Gastroenterology unit at Ain Shams University Hospitals. From: June 2021 to November 2021, after ethical committee approval. Results prospective randomized study demonstrated that the polyp detection rate (PDR) was an increased rate by G-EYE colonoscopy, this difference was statistically significant (P ≤ 0.05) as the total number of patients having polyps detected by G-EYE was 28 (40.60%) and the total number of polyps was 43 polyps while by SC was 15 (21.70%) and the total number of polyps was 19 polyps. There is an advantage for G-EYE over SC in relation to the size of the detected polyps as this study compared the detected polyp size as diminutive (<5 mm), small (6-9 mm) and large polyps (>10 mm) by G-EYE versus SC. For the diminutive polyps, the difference was statistically significant (P ≤ 0.05) favoring the G-EYE, and for small polyps the G-EYE was superior to SC by 3 polyps, while for large polyps there was no difference. G-EYE increased the ADR in comparison with SC [22 (100%) vs 9 (13%) ] respectively as G-EYE colonoscopy detected an additional 15 adenomatous polyps in 13 patients missed from SC colonoscopy. The difference was statistically significant. Fortunately there were very few complications, abdominal pain reported in 3 cases after the end of procedures. Conclusion The study demonstrated that G-EYE is superior to SC in increasing adenoma and polyp detection rate as being more rapid and more precise for detection of diminutive and small adenomatous polyps. However G-EYE could not be done in certain conditions such as diverticulosis, masses, ulcerations or colonic strictures for fear of perforation or incomplete intubation, in this study those patients were excluded from the start as the aim of the study was polyp detection rate difference by balloon assisted colonoscopy (G-EYE) in comparison to the standard colonoscopy (SC).
