Abstract:
Objective To analyze the differences in endoscopic and pathological features between colorectal serrated adenoma (SA) and colorectal traditional adenoma.Methods The endoscopic and pathological features of 80 cases of SA and 160 cases of traditional adenoma diagnosed from June 2008 to October 2013 were retrospectively analyzed.Results The SA patients were younger than the traditional adenoma patients (57.5 VS 62.3,P =0.003 8).The lesions of SA were mostly located in rectosigmoid colon (60％),while the traditional adenoma could be found in rectosigmoid colon (45％),ascending colon (20％) and descending colon (19％).There were significant differences in the lesion's location between two kinds of adenoma (P ＜ 0.05).There were no differences in gender,the size of lesion or endoscopic classification.In terms of the pathological features,SA had the serrated structure,whereas tubular,tubulovillous and villous structure were found in traditional adenoma.Cancer could be found in 1.9％ of SA,which was lower than that of traditional adenoma (P ＜ 0.05).Conclusion Serrated adenoma is different from traditional adenoma on the patient's age,lesion's location and pathological features.It is an unique kind of adenoma with potential malignancy,which should be emphasized in clinical practice.
