| [ Summary ] | Emergency colonoscopy is useful for patients who have symptoms of anal bleeding and colorectal obstruction. The cause of anal bleeding may not only be colorectal tumors, but also inflammatory bowel disease, ischemic colitis, diverticulitis and / or angiodysplasia. There are many types of colorectal polyps which cause anal bleeding, for example adenocarcinoma, villous adenoma, hamartoma, etc. As the skill of endoscopists improves, many large polyps are resected with endoscopy. On the other hand, bleeding after the polypectomies has become one of the greatest reasons for emergency colonoscopy. Moreover, colorectal obstructions arise from advanced colorectal cancer, intussusception, and torsion of the sigmoid colon. Colonoscopic decompression is safe and highly effective treatment for these diseases (especially, obstructions caused by distal side colorectal cancer). |
