A Large Polypoid Vascular Ectasia Removed by Using a Polypectomy With a Detachable Snare in an Asymptomatic Patient
A 50-year-old man was referred to Ajou University Hospital for a large pedunculated polyp, which was found on colonoscopy during a regular health check-up. The patient had no symptoms and no history of gastrointestinal bleeding, such as melena or hematochezia. In the laboratory findings, hemoglobin was 15.3 g/dL, and hematocrit was 43.7%.\nAt the time of colonoscopy, a pedunculated polypoid mass measuring approximately 4 cm, with a long stalk, was found in the sigmoid colon (). The head portion of the polyp had a hyperemic mucosal surface with some folds, but no evidence of hemorrhage. To prevent bleeding during polypectomy, we applied a detachable snare to the base of the mass, and we performed a polypectomy successfully without complications (). Pathologic results showed an edematous submucosa with an obvious dilated vein lined with endothelial cells, which was consistent with a vascular ectasia ().
