Diverticulitis is a complex disease and demands careful cooperation between physician and surgeons, because although it is a benign disease, the presence of complications makes it potentially lethal. For successful management, knowledge of the treatment in past decades should be integrated with current surgical technics. A retrospective review of forty-one patients with perforated diverticulitis revealed a significant decrease in morbidity and hospital stay for the group of patients undergoing the Hartmann procedure versus the group undergoing the classic three stage approach. In addition, the Hartmann group required fewer additional surgical procedures for drainage of abscesses. In view of these results as well as those of others, we believe that resection is the primary goal of therapy. The two stage approach therefore offers significant decrease in morbidity with acceptable mortality.
