[Applicability, safety and efficacy of an ambulatory treatment protocol in patients with uncomplicated acute diverticulitis]

Abstract

Introduction: The aim of this study was to evaluate the applicability, safety and efficacy of an ambulatory treatment protocol in patients with uncomplicated acute diverticulitis.

Patients and methods: All patients diagnosed with uncomplicated acute diverticulitis based on abdominal computed tomography findings during a 2-year period were prospectively included. Patients with vomiting, severe comorbidities, or without an appropriate family environment were excluded. Ambulatory treatment consisted of oral antibiotics for 1 week (amoxicillin-clavulanic 1 g t.i.d. or ciprofloxacin 500 mg b.i.d. plus metronidazole 500 mg t.i.d. in patients with penicillin allergy). A clear liquid diet for the first 2 days and pain control with oral acetaminophen 1 g t.i.d. were also recommended.

Results: Fifty-three patients were diagnosed with uncomplicated acute diverticulitis and 13 patients were excluded. Therefore, ambulatory treatment was initiated in 40 patients. Only two patients (5%) required admission after outpatient therapy was started due to vomiting and persistent abdominal pain, respectively. In both patients, the inflammatory process was successfully resolved by intravenous antibiotic treatment. In the remaining 38 patients (95%), ambulatory treatment was completed without complications.

Conclusions: Ambulatory treatment of uncomplicated acute diverticulitis is safe, effective and applicable in most patients with tolerance to oral intake and with an appropriate family environment.
