Colorectal cancer (CRC) is the second neoplasm responsible for the most cancer-related deaths in the world, with a higher incidence in Europe, North America, and OceaniaPrevention and early diagnosis of CRC have led to a decrease in its incidence and mortality, secondary to the detection and subsequent removal of precursor lesions during colonoscopyScreening with colonoscopy is considered the best method for detecting polyps, with a reduction in mortality from CRC of 29% and reaching up to 47% for distal tumorsCurrently, several techniques have been proposed to improve the identification of polyps in the proximal colon, including dye chromoscopy, digital chromoscopy, cap-assisted colonoscopy, routine rear view of the cecum and ascending colon, and second sequential assessment of the ascending colon.The present study aims to evaluate the impact on polyp detection in a second sequential evaluation of the cecum and ascending colon, with or without the use of indigo carmine chromoscopy, and to discriminate which type of polyps are found by these methods.
