Aim: To study the characteristics of EMR (endoscopic mucosal resection) or ESD (endoscopic submucosal dissection) postoperative pathological examination of colonic polyps in different age groups, and the difference of pathological examination after EMR or ESD operation. Methods: A retrospective analysis was made of the EMR or ESD postoperative pathological data of 100 cases of colonic polyps patients in the Jingzhou Central Hospital digestive internal medicine. The time is from March 2016 to March 2018. Results: In 100 cases of EMR or ESD operation, there are 65 cases of young and middle-aged group. Pathological examination results include: 34 cases of adenomatous polyp, 18 cases of inflammatory polyp, 11 cases of benign tumors, 1 case of malignant tumor, 1 case of hyperplastic polyp. There are 35 cases of elderly group. Pathological examination results include: 27 cases of adenomatous polyp, 2 cases of inflammatory polyp, 2 cases of benign tumors, 4 cases of malignant tumor. 71 cases of complete EMR operation include: 51 cases of adenomatous polyp, 17 cases of inflammatory polyp, 3 cases of benign tumors; 29 cases of complete ESD operation include: 10 cases of adenomatous polyp, 3 cases of inflammatory polyp, 10 cases of benign tumors, 5 cases of malignant tumor, 1 case of hyperplastic polyp. Conclusion: For the pathological examination results after EMR or ESD operation, the proportion of inflammatory polyps in the young and middle-aged group was greater than that in the elderly group. The proportion of adenomatous polyps in the elderly group was larger than that in the young and middle-aged group. The proportion of adenomatous polyps in EMR was greater than that of ESD. The proportion of benign tumors and malignant tumors in ESD was greater than that of EMR. The difference has statistical significance.
