OBJECTIVE: To evaluate the value of colonoscopy in the diagnosis of colorectal cancer.
METHODS: The data of colonoscopy in 1751 patients from May 2003 to June 2006 were retrospectively analyzed.
RESULTS: Of these 1751 colonoscopies, 643 colorectal cancers (36.7%) were detected. The age of most patients was between 40 and 60 years, and hematochezia was the major syndrome for these patients. 351 patients (54.6%) had lump type, 211 (32.8%) ulcerous type, 81 (12.6%) ulcerous infiltration type. 511 colorectal cancers (79.5%) originated from the rectum or sigmoid colon. Simultaneous double primary carcinoma was found in 15 cases (2.3%). Multiple primary cancer was observed in 2 cases. Furthermore 254 colorectal cancers (39.5%) were found to have concurrent colorectal polyps.
CONCLUSION: Colonoscopy of total colon and rectum is very helpful in diagnosis of colorectal cancer, which can reduce the rate of misdiagnosis and improve the survival.
