An intestinal polyp is a mass of tissue, which arises from the bowel wall and protrudes into the lumen. Polyps may be sessile or pedunculated. The incidence of polyps ranges from 7 to 50%. Polyps are most commonly found in the rectum and sigmoid colon and decrease in frequency towards the caecum. Symptoms and signs: Polyps are usually asymptomatic. The most frequent complaint is rectal bleeding, which is usually occult. Abdominal pain and obstruction occur with large polyps. The main concern with polyps is the risk of malignant transformation. Complications of polypectomy: Common complications following polypectomy are bleeding and infection. The risk of bleeding ranges from 0.2 to 1.2%. When patients are on blood thinners, the risk of bleeding increases to 6.8%. Advantages and disadvantages of use of prophylactic clips: Clips can be applied during the procedure itself. They are easy to deploy. No scarring can be observed. Disadvantages: They are expensive, and present a risk of perforation and further bleeding.
