Is the decline in the surgical treatment for diverticulitis associated with an increase in complicated diverticulitis?
PURPOSE: Indications for operative intervention in the treatment of diverticulitis have become unclear. We hypothesized that surgical treatment for diverticulitis has decreased resulting in proportionately more complicated diverticulitis cases (free perforation and/or abscess). METHODS: We conducted a retrospective analysis of patients with diverticular disease in the Nationwide Inpatient Sample from 1991 through 2005. We used diagnostic codes to identify all patient discharges with diverticular disease and then determined the proportion of discharges with diverticulitis, perforated disease, diverticular abscess, and surgical treatment. RESULTS: During the study period, 685,390 diverticulitis discharges were recorded. The ratio of diverticulitis discharges increased from 5.1 cases per 1,000 inpatients in 1991 to 7.6 cases per 1,000 inpatients in 2005 (P < 0.0001). The proportion of patients who underwent colectomy for uncomplicated diverticulitis declined from 17.9% in 1991 to 13.7% in
