Background and Aim: Conventional colonoscopy is the gold standard for colorectal cancer screening. However, a failure rate to complete conventional colonoscopy of more than 10% is reported in the literature. We evaluated whether the therapeutic Fujinon double-balloon endoscope EN-450T5/20 is a valuable tool to intubate the cecum and to carry out all conventional endoscopic procedures after incomplete conventional colonoscopy. Methods: Forty-five consecutive patients with prior incomplete conventional colonoscopy were prospectively enrolled. All but three procedures were carried out under conscious sedation with the patient in the left lateral decubitus position without fluoroscopic guidance. Results: The cecum was reached in 42 of 45 patients (93%) and in 62% additional therapeutic interventions were carried out. Double-balloon colonoscopy required less conscious sedation compared to conventional colonoscopy. No external abdominal compression nor fluoroscopic control was used. The insertion depth of the double-balloon endoscope did not exceed the working length of a conventional colonoscope. Conclusions: The present study illustrates that the concept of double-balloon endoscopy is a valuable alternative to reach the cecum after prior incomplete conventional colonoscopy, especially due to redundant colon and colonic loop formation. The procedure requires less conscious sedation and no fluoroscopic control, but allows all conventional endoscopic interventions.
