    Abstract:
    Objectives: Colonoscopy is the gold standard diagnostic method for colorectal cancer (CRC) screening. Despite the progress in the endoscopy technology field, a small percentage of colonoscopies is still incomplete. The reasons for that are mostly associated with anatomic features, such as fixed, angulated, long and loopy colon, intra-abdominal adherences and female gender. To overcome such difficulties, the usefulness of scopes different from conventional adult colonoscope (CF), such as paediatric colonoscope (PCF), gastroscope (GIF), single and double balloon enteroscope (SBE and DBE, respectively), has been shown in literature. Our retrospective study aims to evaluate the caecal intubation rate using a SBE without the overtube in patients who previously underwent an incomplete procedure with a different scope.Methods: Patients with a previous incomplete colonoscopy with CF, PCF or GIF were retrospectively enrolled through the analysis of a dedicated database. The enteroscope used was the Olympus Enteropro Single Balloon SiF-Q180 with no overtube. Complete colonoscopy was defined as successful caecal intubation.Results: SBE was used to scope 47 adult patients, mostly female, and it led to a complete procedure in 91% of them. The most frequent reason for an incomplete procedure even with the use of SBE was a fixed and angulated colon.Conclusions: Colonoscopy performed with SBE was safe and no adverse events during and/or after the procedure occurred. Our results suggest that SBE with no overtube is a useful and valid alternative to other type of scopes in difficult cases, especially those related to fixed/angulated colon and in female gender.
