Medical and surgical therapy in diverticular disease: a comparative study.

The course of 132 patients with documented acute diverticulitis was analyzed: 99 patients treated medically and 33 patients treated surgically were followed for an average of 9.2 years. Seventy-three per cent of the medical group and 79% of the surgical group had no further symptoms or hospital admissions as a result of their diverticular disease once they were recovered from the acute episode. For three-quarters of the patients, therefore, acute diverticulitis occurred as a single episode that responded to either medical or surgical management. Considering the morbidity and cost to the patient, the treatment of the patient recovered from acute diverticulitis should be medical, with operation reserved for complications.
