Diverticula are small, bulging pouches that can form in the lining of your digestive system. They are found most often in the lower part of the large intestine (colon). Diverticula are common, especially after age 40, and seldom cause problems.
The treatment of diverticulitis depends on how serious symptoms are. Some people may need to be in the hospital, but most of the time the problem can be treated at home. Outpatient management has traditionally consisted of a clear liquid diet, oral broad-spectrum antibiotics, and follow-up in two to three days. The usual practice in the United States for the treatment of diverticulitis includes broad-spectrum antibiotics against gram-negative rods and anaerobic bacteria.
Acute diverticulitis (AD) results from inflammation of a colonic diverticulum. It is the most common cause of acute left lower-quadrant pain in adults and represents a common reason for acute hospitalization, as it affects over half of the population over 65 years with a prevalence that increases with age. Although 85% of colonic diverticulitis will recover with a nonoperative treatment, some patients may have complications such as abscesses, fistulas, obstruction, and /or perforation at presentation
