Pathological and endoscopic features of rectocolic lesions

ABSTRACT

Study 480 cases of rectocolon endoscopic biopsies, to compare the clinical features with the features and microscopic diagnosis. Results: the patients between 50 and 70 years old had the rate of highest catch a diseases and malignant lesions. There was no difference in the cancer ratio between male and female. The percentages of 4 groups included: malignant tumors, inflammatory lesions, polyps and benign tumors, were about 48%, 30%, 13.75% and 6.87%. Malignant tumors occur mainly in the rectum (65.36%) and in the sigmoid colon (9.95%). Most of malignant tumors in the colon and rectum (96%) were adenocarcinoma. The true-positive percentage of endoscopic diagnosis (confronted with microscopic finding) in the cancer group was 70.56%
