The ideal colonoscopy preparation requires that the bowel is clean and free of fecal matter, which may block the suction channel. Also certain drugs should be avoided such as iron tablets, aspirin or anticoagulants for 4-5 days prior to the procedure. We describe a patient in whom cinnamon chewing gum taken the night before was mimicking colonic polyps. Case Report: A 55-year-old male with history of constipation and a few episodes of mild rectal bleeding after straining was scheduled for colonoscopy. He denied weight loss or family history of colonic carcinoma. His physical examination was unremarkable and the routine labs within normal limits. Even though it was clinically evident that the bleeding was from an anorectal source, because of his age he underwent full colonoscopy. The standard bowel preparation with liquid diet and one gallon of “Golytely” solution the evening before was applied. Colonoscopy was performed up to the cecum. Preparation was adequate. Grade 1-2 internal hemorrhoids were noticed otherwise the colonic mucosa was normal throughout. In the cecum opposite to the ileocecal valve there was a polypoid lesion 7-8 mm in size, pinkish, round, smooth, nearly attached to the mucosa looking like an adenomatous polyp. After the photos, the trainee was prepared for polypectomy when it was noticed that “the polyp” moved away from the original position. During withdrawal a similar, but smaller piece was noted at the splenic flexure. By asking the patient he admitted that he took red cinnamon gum the night before the procedure and he kept the empty pack in his pocket, which gave to the endoscopy staff. Pathology report for documentation: “vegetable matter, consistent with foreign body.” Conclusion: Cinnamon chewing gum may mimic adenomatous colonic polyps but most important because of their consistency any gums may block the suction channel more than the feces; therefore recommendation to the patients to avoid chewing gum the day before colonoscopy should be made.
