Abstract
PURPOSE: Antibiotics are widely used in the treatment of uncomplicated left-sided colonic diverticulitis. In Asian countries, however, right-sided colonic diverticulitis is more common than left-sided colonic diverticulitis. The aim of the present study was to evaluate the need for antibiotics in the treatment of uncomplicated right-sided colonic diverticulitis in an Asian population. METHODS: Patients were randomized to two management strategies: antibiotics and no antibiotics. At 4-6 weeks after discharge, the patients in both groups underwent computed tomography or were contacted by phone to confirm the effectiveness of the treatment. The primary end point was the treatment failure rate of the initial treatment, and secondary end points were the length of hospital stay and total admission costs. RESULTS: Patients were randomized to treatment with (61 patients) or without (64 patients) antibiotics. The rates of treatment failure in the antibiotics and no antibiotics groups were 1.7% and 4.6%, respectively, with no significant difference (P = 0.619). There was also no significant difference in the length of hospital stay between the groups (P = 0.983). Total admission costs were lower in the no antibiotics group than in the antibiotics group (US$1004.70 vs US$1112.40, respectively, P = 0.037). CONCLUSION: Conservative management of uncomplicated right-sided colonic diverticulitis without antibiotics shows similar treatment failure rates and length of hospital stay, and is associated with lower hospital costs, compared with standard antibiotic treatment. Therefore, conservative management can be considered as a safe treatment option. TRIAL REGISTRATION: ClinicalTrial.gov No. NCT02314013.
