Overview
Diverticulitis natural history is not well understood, but some studies have shown the disease to take a benign course if left untreated. Diverticulitis can cause many complications that can sometimes be fatal. These complications include abscess, perforation, peritonitis, and fistula formation. Prognosis of diverticulitis is excellent and conservative treatment is successful in 70 to 100 percent of patients.
Natural History
The natural history of diverticulitis is still not well understood. However, some studies have shown the disease to take a benign course with a low incidence of complications if left untreated.[1][2]
Complications
In complicated diverticulitis, bacteria may subsequently infect the outside of the colon if an inflamed diverticulum bursts open. If the infection spreads to the lining of the abdominal cavity (peritoneum), this can cause potentially fatal peritonitis. Sometimes, inflamed diverticula can cause narrowing of the bowel, causing an obstruction. Also, the affected part of the colon could adhere to the bladder or other adjacent organs, causing a fistula. These complications always require treatment to prevent them from progressing and causing serious illness.[3]
Abscess
- Abscess formation may take place in cases of diverticulitis.[4]
- The abscess can be detected by CT scan and can be resolved with antibiotics. If the abscess persists, cutaneous drainage is recommended.
Perforation and peritonitis
- Perforation can lead to secondary peritonitis due to chemical irrigation by feces.[5]
- This is rare but may be fatal.
Fistula
- Fistula formation is another complication of acute diverticulitis. It occurs between the colon and its adjacent structures, especially the bladder forming the colovesical fistula.
- Genitourinary manifestations may present as dysuria.[6]
Prognosis
In patients with acute uncomplicated diverticulitis, conservative treatment is successful in 70 to 100 percent of patients and mortality is negligible.[7]
