Podcast 727: Antibiotics for Diverticulitis

Contributor: Aaron Lessen, MD

Educational Pearls:

  • Classically, diverticulitis is diagnosed via CT scan and patients are discharged home on antibiotics if they are without complication
  • The DINAMO study is a multicenter open-label RCT that evaluated if it is safe to not give antibiotics to patients with mild acute diverticulitis
  • Found no difference in readmission, return visits to ED, pain control, or likelihood of surgical intervention between the group that was sent home with antibiotics and the group without
  • Medical societies have not reached a consensus on this issue, likely further studies need to be completed
