Further Inpatient Care
- Emergency colectomy is performed when severe complications arise or when the patient does not respond to medical treatment. Complications requiring surgical intervention include the following: purulent peritonitis, uncontrolled sepsis, fistula, and obstruction. In one retrospective study of over 3000 patients, about 20% of patients admitted for acute diverticulitis required emergency colectomy.
- Elective resection of the involved bowel segment after 2 episodes of uncomplicated diverticulitis to prevent further attacks has been advocated for years. In addition, earlier resection for younger patients with diverticulitis as well as for patients who are immunocompromised has been proposed. As most complicated diverticulitis occurs on the first presentation and data for elective resection have come from small retrospective studies, this recommendation remains controversial.
- Successful percutaneous drainage of a diverticular abscess has not been associated with greater recurrence or more severe disease and does not necessitate elective colectomy.
Further Outpatient Care
- After recovering from acute diverticulitis, patients should have their colons examined to rule out malignancy. Current modalities include colonoscopy, barium enema, and CT colography (virtual colonoscopy).
- Biopsy of suspicious lesions or strictures can be performed during colonoscopy, which is advantageous.
- Virtual colonoscopy may be helpful in evaluating diverticulitis in the elective setting. This procedure combines insufflation of the colon in conjunction with a CT scan to provide data that allow computer generation of a 3-dimensional image. At this time, though, the technology is not widely available and does not allow sampling of suspicious lesions.
Deterrence/Prevention
- A lifelong high-fiber diet for those with asymptomatic diverticular disease may reduce the incidence of diverticulitis and its complications.
- According to a large study in the United Kingdom, a high-fiber diet and a vegetarian diet were each significantly associated with lower risk of diverticular disease-related hospital admission or death.[9]
Complications
- Abscess
- Intestinal fistula
- Intestinal perforation
- Intestinal obstruction
- Peritonitis
- Sepsis and septic shock
- Diverticular bleeding (more common in diverticulosis than diverticulitis)
Prognosis
- Prognosis depends on the severity of illness, the presence of complications, and any coexisting medical problems. Younger patients with diverticulitis may have more severe disease, possibly due to a delay in diagnosis and treatment.
