Abstract

Background : It is not unreasonable to assume that the risk of post-polypectomy hemorrhage is correlated with supplying artery diameter. The aims of this study were to analyze the correlation between morphological parameters and supplying artery diameter in pedunculated colorectal polyps.<br>Method : A total of 47 pedunculated colorectal polyps in surgical specimens of colorectal cancer (adenoma, 40 ; carcinoma in adenoma, 4 ; hyperplastic polyp, 3) were used. Histological pictures of the sliced specimens stained with H&E were transferred to a personal computer for the morphological parameters and supplying artery diameter.<br>Results : The polyp head was 5.9±2.8mm and 4.8±1.9mm in vertical and horizontal diameter, respectively. The polyp stalk was 2.0±0.5mm and 5.8±3.2mm in diameter and length, respectively. The mean supplying artery diameter was 95.7±33.0μm. The artery diameter was found to be significantly correlated with the stalk diameter (r=0.36, p<0.0001), but less correlated with the head diameter (r=0.24, p>0.05).<br>Conclusion : the risk of post-polypectomy hemorrhage was considered to increase with stalk diameter. When polypectomy is performed for polyps with larger stalk diameter, squeezing of the stalk by a clip or snare device may be of prophylactic value for post-polypectomy hemorrhage.
