Background: Management of diverticular disease has undergone a paradigm shift, with movement towards a less invasive management strategy. In keeping with this, outpatient management of uncomplicated diverticulitis (UD) has been advocated in several studies, but concerns still remain regarding the safety of this practice.
Aim: To assess outcomes of out-patient management of acute UD.
Methods: A comprehensive search for published studies using the search terms 'uncomplicated diverticulitis', 'mild diverticulitis' and 'out-patient' was performed. The primary outcomes were failure of medical treatment. Secondary outcomes were recurrence rate at follow up and medical cost savings.
Results: The search yielded 192 publications. Of these, 10 studies met the inclusion criteria including 1 randomized controlled trial, 6 clinical controlled trials and 3 case series. There was no difference in failure rates of medical treatment (6.5 vs. 4.6%, p = 0.32) or in recurrence rates (13.0 vs. 12.1%, p = 0.81) between those receiving ambulatory care and in-patient care for UD. Ambulatory treatment is associated with an estimated daily cost savings of between 600 and 1,900 euros per patient treated. Meta-analysis of data was not possible due to heterogeneity in study designs and inclusion criteria.
Conclusion: Ambulatory management of acute UD is reasonable in selected patients.
