Abstract:
Objective To investigate the relationship between early colonic cancer and the pit patterns of abnormal colonic mucosa. Methods We examined the pit patterns of 124 polypi in 139 patients by magnifying colonoscopy and stereomicroscopy, and compared the relations between the pit patterns and pathological diagnosis of polypi. Results 5 cases of LST(laterally spreading tumor)and 9 cases of advanced cancer were found out of 124 polypi in 139 patients. 1 among these 5 cases of LST showed Ⅲ L pit pattern, and 4 showed Ⅳ pit pattern with both magnifying colonoscopy and stereomicroscopy. Magnifying colonoscopy showed high coincidence rate with stereomicroscopy. Conclusion Pit patterns are found to be very important in disguishing tumorous lesions from non-tumorous lesions, and to discover early colonic cancer. Ⅴ pit pattern indicates that the polyp is carcinomatous.
