Abstract:
Objective: To examine endoscopic features of early colorectal carcinomas smaller than 2 cm. Methods: A total of 191 pa-tients (201 early colorectal carcinomas) who were definitely diagnosed with early colorectal cancer smaller than 2 cm between Janu-ary 2014 and December 2017 in Beijing Shijitan Hospital, Capital Medical University were enrolled. The patients'clinical characteris-tics, endoscopic and pathological data were retrospectively analyzed. Results: There were more male patients than female patients (1.81:1) in the study population; distribution of lesions was higher in the left colon than in the right colon (141/201). Group 1 had a higher number of IIa lesions (20/67, P=0.037) and a lower number of Ip lesions than Group 2 (52/134, P<0.01). Conclusions: There are special characteristics in distribution and endoscopic manifestations of early colorectal carcinoma. Lesion size was less than 1 cm in 67 (191 cases of early colorectal cancer) early colorectal carcinoma cases; however, a high-risk adenoma is defined as a lesion larger than 1 cm in size. Therefore, regardless of lesion size, if fractionation, echinodermata, congestion, erosion, expansion, and depression are observed, the lesion should be assessed in detail for the sake of carcinogenesis.
