A rare case of appendiceal polyp from screening colonoscopy – A case report

Background: Appendiceal adenomatous polyps are rare and present diagnostic challenges. The reported incidence of these polyps during autopsy ranges from 0.004% to 0.08%. The identification of appendiceal polyps during colonoscopy is uncommon, and there is limited literature on this subject. This case highlights the importance of thorough assessment of the appendix during colonoscopy. Case Presentation: A patient with a history of chronic constipation presented with complaints of per rectal bleeding and rectal pain. The patient had previously undergone a surveillance colonoscopy several years ago, which showed normal findings. During the current colonoscopy, a 0.5 cm x 0.5 cm polyp was identified at the appendiceal orifice. Discussion: Appendiceal polyps are rare findings during colonoscopy, and their detection can be difficult due to the anatomical location of the appendix. The significance of these polyps lies in their potential to cause complications such as malignancy, intussusception, or chronic appendicitis. While guidelines for the follow-up of patients with appendiceal orifice polyps are limited, this case emphasizes the need for careful examination of the appendix during colonoscopy. Conclusion: A thorough assessment of the appendix during colonoscopy is essential for detecting appendiceal polyps and preventing potential complications. Further research and clearer follow-up guidelines are needed for patients with appendiceal opening polyps.
