Core Tip

Core tip: The natural history of sigmoid diverticulitis is poorly understood. While there is a clear lack of uniformity in terminology, which results in difficulties interpreting and comparing findings between studies, this comprehensive review demonstrates the benign nature of simple sigmoid diverticulitis. The overall recurrence rate is relatively low. Several risk factors are found to be associated with recurrence.
