Abstract. – While the treatment of complicated diverticular disease (DD) is standardized, the approach to the symptomatic DD and prevention of relapsing complicated DD is still debated. An open question is whether nonabsorbable antibiotics may reduce the incidence of major complications of DD. We wanted to retrospectively analyze the prevalence of this disease in a large population of patients undergoing colonoscopy in our center in the last 10 years. Patients with symptomatic or complicated DD were treated with rifaximin 1,200 mg/die for 10-12 days during the acute phase in addition to the appropriate systemic antibiotics, followed by a prophylactic regimen with 800 mg/die for 7 days every month. The patients were followed up to December 2003, and the incidence of new complications and the relapses of symptomatology were determined. A total of 11,344 patients were screened. Of them, 2,287 showed an anatomical diverticulosis, and 408 had a diagnosis of complicated DD. The results indicate that the prevalence of DD – either in the uncomplicated or complicated form – in our area (Abruzzo, Italy) is identical to that of European countries, whose diet is characterized by a low amount of fiber and a high content of calories and refined sugars. Along a period of 10 years, a relapsing symptomatology of DD was observed in 112 patients treated with rifaximin (4.89%), while new complications of the DD were observed in 27 patients (1.18%). The comparison of these data with those of larger published series suggests a possible role of rifaximin in the prevention of DD main complications.
