Colonoscopy at a Combined District General Hospital and Specialist Endoscopy Unit: Lessons from 505 Consecutive Examinations

Abstract

Provisional reports from the Intercollegiate British Society of Gastroenterology National Colonoscopy audit show completion rates of 57–77%for the procedure and poor levels of training and supervision. We prospectively audited all aspects of colonoscopy performed at a combined district general hospital and specialist endoscopy unit. Details of referral, examination, endoscopist, complications and follow-up were recorded and patients were sent questionnaires for long-term follow-up. 505 patients (246 male) underwent colonoscopy by 27 different endoscopists. Their median age was 57 years (range 13–92) and 93%were outpatients. 64% patients were symptomatic and 36%were having surveillance or follow-up colonoscopy. The overall caecal intubation rate was 93%, with little difference between surgeons, physicians and experienced trainees (89%, 92%, 94%) and specialist endoscopists (98%). In only one case was an inexperienced trainee (<100 procedures) unsupervised. Pain scores estimated by the endoscopist were well matched with those given by the patient—medians 29 and 26 (maximum 100) respectively. Median satisfaction score was 96 (maximum 100). Polyp pick-up rate was 26.9%and there were 11 new cancers. 16 (3%) minor immediate complications were recorded—5 oversedation, 6 vasovagal attacks, 3 polypectomy haemorrhages and 2 mucosal injuries (neither requiring treatment). 3 patients died within 6 months of follow-up but no death was colonoscopy related. Completion rates in this setting were adequate for all endoscopists studied. Patient satisfaction with the procedure was high and very few immediate or long-term complications were encountered.
