To evaluate the values of clinical findings in differential diagnosis between Crohn's disease (CD) and intestinal tuberculosis (ITb), so that better diagnosis strategies could be found, we analysed the records of 30 patients with ITb and 30 patients with CD retrospectively. We reviewed the cardinal symptomatic and physical, radiological, colonoscopic, pathological findings in the patients. Some cardinal symptomatic and physical, radiographic and colonscopic features of CD and ITb were positive correlation. Its Pearson correlation coefficients were 0.976, 0.953 and 0.961, respectively (p = 0.000, 0.003 and 0.000). Some histological features of CD and ITb had no correlation. Its Pearson correlation coefficient was 0.140 (p = 0.765). It is difficult to differentiate CD from ITb in clinical practice. The differential diagnosis depends largely upon colonoscopy and histopathology.

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.
