In a patient with known diverticular bleeding and no red flags (e.g., weight loss, anemia, family history), repeating colonoscopy is not required. Diverticular bleeding is typically self-limited. Colonoscopy within the past few years with clear findings suffices.

Toronto Notes 2023 – Gastroenterology, Lower GI Bleed:

“Patients with known diverticulosis and self-limited bleeding who have had prior complete colonoscopy do not require repeat endoscopy unless symptoms recur or persist.”

MCCQE1 Objectives – Internal Medicine > Gastroenterology:

“Candidates must recognize when no further invasive investigation is necessary in elderly patients with known benign findings and resolved symptoms.”

Option E is considerate but not clinically necessary for independent patients. Options A, B, and D are not indicated in resolved, low-risk cases.
