| Abstract | Background and aims: There is a continuing demand for the provision of open-access endoscopy services. While open-access gastroscopy is now a well-established practice in most hospitals, open-access flexible sigmoidoscopy (OAS) is not yet available to the same extent. We present our early experience with OAS, a new service provided by our unit. Patients, methods and results: Over a 12-month period, 255 flexible sigmoidoscopies were carried out (139 OAS and 116 hospital-initiated sigmoidoscopies, HIS). Referral criteria for sigmoidoscopy were similar in both groups, with rectal bleeding and change in bowel habit being the most frequent. Results: The two groups were comparable with regards to age and gender, but patients referred for OAS had symptoms for shorter duration than those referred for HIS (30 +/- 5.6 months v. 101 +/- 28 months, P < 0.00001). The diagnostic yield for OAS was 44% and for HIS 29% (P = 0.01). Significant pathology (colorectal cancer, polyps and newly diagnosed inflammatory bowel disease, colonic strictures) was detected in 31 patients (22%) in the OAS group and 12 patients (10%) in the HIS group (P = 0.02). Six cancers were diagnosed (5 OAS, 1 HIS), all staged Duke A. The waiting times for OAS and HIS were 3.1 +/- 0.3 weeks and 11.4 +/- 1.2 weeks, respectively (P = 0.0001). The diagnostic yield of fibre-optic endoscopy was independent of duration of symptoms, although patients referred for OAS with rectal bleeding and/or diarrhoea had a higher diagnostic yield (55/125, 44%). Conclusion: OAS is feasible and effective, with a high diagnostic yield. Such service can usually be provided with minimal added resources. (C) 2001 Lippincott Williams & Wilkins, Inc. |
