This study examined clinical outcomes of patients with complicated diverticulitis managed nonoperatively. The researchers reviewed 256 patients diagnosed with complicated diverticulitis via CT scan over a 14-year period. 99 patients were initially managed nonoperatively with antibiotics and some receiving percutaneous drainage. These patients had a high rate of recurrence (46.4%) but a low risk of requiring emergency surgery. The risk of recurrence did not differ significantly between younger (<50 years) and older patients. While recurrence rates were high, the risk of complications requiring emergency surgery was low for patients managed nonoperatively initially. Patient factors, comorbidities, and preferences should all be considered when determining treatment for complicated diverticulitis.
