BACKGROUND: Diverticulitis in Asians is a different disease entity from Western counterparts. Few Asian studies have evaluated the management of acute Hinchey Ia diverticulitis with consideration for outpatient management. The purpose of this study was to evaluate the outcomes of Asian patients with Hinchey Ia acute diverticulitis. METHODS: A retrospective review of all patients who were treated for Hinchey Ia acute colonic diverticulitis between 2012 and 2014 was performed. All patients were diagnosed on computed tomography (CT). RESULTS: There were 129 patients with Hinchey Ia acute diverticulitis. Fifty-five (42.6%) patients were male, and the median age was 54 years (range, 30-86). Eighty-seven (67.4%) patients had right-sided diverticulitis. Most patients were treated empirically with intravenous ceftriaxone and metronidazole (89.1%). They were then discharged with oral antibiotics. Only 6.1% of patients had a positive blood culture. The median length of stay in the hospital was 4 (range, 3-4) days. Only three (2.3%) patients were readmitted for acute diverticulitis within 30 days. They were managed with antibiotics and discharged well. The repeated CT scans reconfirmed Hinchey Ia diverticulitis. No patients required emergency surgery, and there were no 30-day mortalities. CONCLUSION: Asian patients with Hinchey Ia diverticulitis recovered well with conservative management and could be amenable to outpatient therapy. Future prospective studies should be performed amongst Asians to evaluate managing this condition in an ambulatory setting.
