Overview
The mainstay of therapy for acute diverticulitis is usually conservative medical management, including bowel rest, IV fluid resuscitation, and broad-spectrum antimicrobial therapy that covers anaerobic bacteria and gram-negative rods. Patients who have recurring acute attacks or who develop diverticulitis-associated complications, such as peritonitis, abscess, or fistula, require surgery either immediately or on an elective basis.
Medical Therapy
Uncomplicated Diverticulitis
- A 7-10 day course of oral, broad-spectrum antibiotic therapy is the first line of therapy for acute uncomplicated diverticulitis.[1]
- Hospital admission is indicated for elderly patients and patients with multiple comorbidities, compromised immune systems, inability to tolerate oral hydration, or failure to improve despite appropriate antibiotic therapy.
- Hospitalized patients often require bowel rest, nasogastric tube placement, and parenteral antibiotics.[2]
- Outpatients should be advised to follow a liquid diet for 2-3 days, after which a regular diet may be resumed slowly.
- There is no robust evidence that suggests that a low residue diet prevents the progression of diverticulosis to an acute case of diverticulitis.[3][4]
- Routine colonoscopy is recommended after the resolution of an acute diverticulitis to exclude colon cancer or any other underlying etiology.[5]
