Office procedures. Flexible sigmoidoscopy.

The flexible sigmoidoscope is a flexible fiberoptic or video endoscope designed to examine the mucosal surface of the sigmoid colon and rectum. The flexible sigmoidoscope represents a technologic advancement over the earlier rigid sigmoidoscopes that were hindered by the relatively short length of bowel they could visualize and the rather uncomfortable examination the patient was required to endure in its use. It has clinical usefulness in the evaluation of many disease processes that involve the rectum and sigmoid colon.

Colonoscopic diagnosis of minimal change colitis in patients with a normal sigmoidoscopy and normal air-contrast barium enema.

8 patients with normal sigmoidoscopic appearances and normal results by high-quality air contrast barium enema had substantial or total colitis diagnosed for the first time at colonoscopy performed within a month of the radiological examination. Colitis was confirmed in all 8 patients by histological examination of biopsy specimens. Barium enema radiographs were independently reviewed by three experienced observers who also reviewed other normal and abnormal radiographs. One observer regarded all 8 sets of radiographs from the patients with colitis as being of normal appearance, and 4 patients were reported as having normal radiographs by all three observers. All 7 of the rectal biopsy specimens taken showed histological features of inflammatory bowel disease. This emphasises the importance of performing a rectal biopsy in patients with gastrointestinal symptoms of unknown cause.

Rethinking patient satisfaction: patient experiences of an open access flexible sigmoidoscopy service.

The high morbidity and mortality rates for colo-rectal cancer in Teesside, UK, have led to the initiation of an open access service in two local National Health Service Trust hospitals. This paper reports the results of a pilot patient satisfaction study of the service using a combination of participant-observation, in-depth interviews and questionnaire methods. Although offering a standardised service, ethnographic study revealed interesting differences in practice and follow-up procedures between the two hospitals. Patients, both verbally and on paper, expressed high levels of satisfaction with the services offered at both hospitals, yet in-depth, qualitative research revealed a more complex picture. The evidence from this research will be used to argue that standard consumer satisfaction questionnaires of health provision are inadequate indicators of patients' experience of health care delivery.

The yield of flexible sigmoidoscopy and double-contrast barium enema in the diagnosis of neoplasms in the large bowel in patients with a positive Hemoccult test.

BACKGROUND AND STUDY AIMS: In an ongoing screening study of 68,306 patients for early detection of colorectal cancer, those with a positive Hemoccult II test (H2) were examined with a flexible sigmoidoscope (60 cm) (FS) and double-contrast barium enema (DCE). The aim of this study was to compare the results of FS and DCE examinations in the rectum and the sigmoid colon, and to evaluate the benefit of DCEs. PATIENTS AND METHODS: 1831 FS and DCE examinations were performed on the basis of positive H2 tests (90% acceptance rate for positive Hemoccult tests). The radiologists were unaware of the endoscopic findings. One hundred and thirty-five patients underwent total colonoscopy due to abnormalities found on FS or DCE, or both. All patients were followed-up through various Swedish cancer registers (range: 50-145 months). RESULTS: The sigmoidoscope was fully introduced in 71% of cases, and the mean time for the examination was 5 minutes. The combination of FS and DCE detected 235 adenomas of 1 cm and more, and 81 cancers which were in Dukes stages A (n = 29), B (n = 22), and C (n = 23). Twenty-one cancers (26%) and 24 adenomas (10%) identified on DCE were above the rectosigmoid area. The rate of overlooked adenomas (> or = 1.0 cm) and cancers was 22 and five for FS in the rectosigmoid area, and 55 and 15, respectively, for DCE. Adenomas found in the rectosigmoid area were only rarely associated with more proximal adenomas of 1 cm and more (1%). CONCLUSIONS: This approach-screening by FS and DCE, and selective use of colonoscopy in case of abnormalities-leads to the diagnosis of significant colonic tumors (larger adenomas and cancers) in 17.7% of cases; only two of eighty-three cancers (2.4%) were overlooked with this method.
