title: Evaluation and analysis of colonoscopy in the diagnosis of 186 cases of ulcerative colitis patients.
abstract: The objective of this study was to evaluate the diagnostic value of colonoscopy plus biopsy in patients with ulcerative colitis (UC). Retrospective analysis was performed on clinical data in 186 cases. Erosions, or ulcers, together with mucosal hyperemia and oedema were the most common manifestations of colonoscopy in 87% of patients. In about 56.4% of 186 cases, such manifestations occurred in the rectum and the sigmoid colon. Nearly 65.6% of the patients had a chronic intermittent clinical course. One case developed colon cancer, and another case had toxic megacolon; each case represents 0.05% of the total 186 patients. Therefore, prevalence of both malignancy and complication is low. Colonoscopy plus biopsy is considered to be the major means of the diagnosis of UC, demonstrating its value in differential diagnosis.
