Background and Aims: This study aims to evaluate the role of an advanced endoscopist to study the entire colon after an incomplete colonoscopy. Methods: All patients with an elective incomplete colonoscopy performed under deep sedation in our department between January 2010 and October 2016 were included. Patients with a colonic stenosis, an inadequate bowel preparation, or a colonoscopy performed without deep sedation were excluded. Included patients were followed up to evaluate if and what type of subsequent examinations (colonoscopy by an advanced endoscopist, single-balloon enteroscopy [SBE], and/or CT colonography) was performed to complete the study of the entire colon. Lesions found during these subsequent examinations were also recorded. Results: Ninety-three patients had an incomplete colonoscopy, with no diagnosis of colorectal cancer (CRC) and a high-risk polyp rate of 5.4% (n = 5). Seventy-seven patients with incomplete colonoscopies underwent subsequent examinations, namely CT colonography in 45.5% (n = 35), colonoscopy by an advanced endoscopist in 53.2% (n = 41), and SBE in 13% (n = 10). In the 49 patients who performed either colonoscopy (n = 39) or SBE (n = 10) by an advanced endoscopist, the cecal intubation rate was 100%, and high-risk polyps were found in 26.5% (n = 13) and CRC in 4.1%. CT colonography revealed findings consistent with polyps and CRC in 22.9% (n = 8) and 2.9% (n = 1) of the cases, respectively. Colonoscopy was further repeated in 6 patients with suspected polyps in CT colonography, confirming the initial diagnosis in 5 patients. Conclusions: Colonoscopy by an advanced endoscopist achieved cecal intubation in all patients, representing a good choice after an incomplete colonoscopy.
