•Patients referred St Mark's endoscopy unit for a colonoscopy who are known to have a colon that is technically challenging to colonoscopy, i.e. failed colonoscopy due to technical difficulties in the past or have had a 'difficult' colonoscopy in the past (as described in a previous colonoscopy report), or who fit one or more of the criteria that predict a technically challenging colonoscopy i.e.:
•1. A low body mass index
•2. A low waist-to-hip ratio
•3. Female gender
•4. Over 60 years of age
•5. A past surgical history of hysterectomy
•6. A longstanding history of constipation and/or haemorrhoids
•7. A history of known sigmoid colon disease (e.g. known diverticular disease)
•8. The presence of a known long, redundant colon as identified by diagnostic imaging

•1. Patients with contraindications to conscious sedation
•2. Patients with contraindications to colonoscopy
•3. Patients with latex allergy (as the balloons on the DBC endoscope are made of latex)
•4. Patients who are unwilling to have a colonoscopy or are unwilling to take part in the study
•5. Patients lacking capacity to give informed consent
