    Abstract:
    INTRODUCTION: Acute diverticulitis represents a common surgical condition and one of the leading gastrointestinal causes of hospital admissions in Western societies. The aim of the study is to examine the distribution, management and cost to healthcare of complicated diverticulitis and compare those to uncomplicated diverticulitis. METHODS: The case-control study was performed for patients with acute diverticulitis in Lyell McEwin Hospital in Adelaide, South Australia. Data were collected for patients presented from January 2015 to December 2017. Consecutive patients with acute diverticulitis confirmed by computed tomography were included in the study. Patients recruited for the study were divided into two groups. Patients presenting with Hinchey Ia diverticulitis were classified as 'uncomplicated diverticulitis'. Patients who presented with Hinchey Ib, II, III or IV diverticulitis were classified as 'complicated diverticulitis'. The Hinchey classification was based on the radiological reports of CT scans. RESULTS: From 2015-2017, 116 cases were screened for the study, 10 of which were excluded due to not having CT diagnosis. A total of 106 consecutive cases of acute diverticulitis were recruited for the study. Forty-four cases had complicated diverticulitis. Sixty-two cases with uncomplicated diverticulitis were allocated as a control group. The distribution of cases spanned through all age groups. There were nine cases (20.9%) in the 30-39 age group in the complicated diverticulitis compared to eight cases (12.9%) in the uncomplicated group with odds ratio 1.7 (0.61-4.92). The mean length of stay of the complicated diverticulitis group was 7.74 days compared to 3.93 days of the uncomplicated group with a p value of 0.000235. Nine (20%) cases of the 44 complicated diverticulitis cases were managed operatively, while 35 (80%) of the complicated diverticulitis group and all of the uncomplicated (control) group were managed conservatively. Localized perforations were 24 cases (54.5%) of the complicated diverticulitis group and collections were 18 cases (40.8%). Those cases collectively represented the majority of the complicated group. CONCLUSION: Complicated diverticulitis increases the length of stay significantly in acute diverticulitis cases that are requiring hospital admission despite conservative management in 80% of the cases. Younger age groups represent a significant percentage of both complicated and uncomplicated diverticulitis. In the study population, the percentage of the younger age group was higher in complicated diverticulitis compared to uncomplicated diverticulitis, although this increased risk did not reach statistical significance. This will need to be further investigated in future studies.
