An initial ultrasound - and CT scanning only if this investigation proves negative or inconclusive - provides the best results in terms of imaging. There is no evidence substantiating the efficacy of routine antibiotic administration to patients with clinically mild and uncomplicated diverticulitis. Pericolic or pelvic abscesses can initially be treated with antibiotics, possibly in combination with percutaneous drainage; surgical intervention is only necessary if this treatment regimen fails.
