**Abstract**

Acute diverticulitis is one of the most common surgical causes of admission to Emergency Departments in Western Countries. Although most of the cases can be managed conservatively or electively, a number of them will require an emergency surgical treatment. Among these patients, an even smaller number of them will present with a full-blown catastrophic septic shock. These minorities of cases have accounted for a significant part of the overall mortality and morbidity of complicated acute diverticulitis itself. The implementation of Damage Control strategies has shown to be useful also in these septic catastrophes, where a profound derangement of physiology makes unsafe a classic approach. Damage Control, as we intend it, is not a surgical "technique." A close collaboration between different specialties brought forth a strategy of treatment. The Surgeon, the Anesthetist, and the Intensivist are the three most involved specialists in the treatment of these cases. It is paramount for them to learn how to work side by side and in harmony, since the patients will benefit from each-one's input in their care.
