CT-scan is now the best exam for diagnosis of acute diverticulitis, classification of its severity, and for follow-up. It can also, when necessary, allow percutaneous drainage of pericolic abscesses. Treatment of acute diverticulitis is most often conservative. Surgery outside acute events is now considered as a technique with extremely low morbidity and mortality. In this situation, laparoscopy represents nowadays the technique of choice for safe sigmoid surgery.
