Acute left colonic diverticulitis in the emergency setting: from diagnosis to treatment.

ABSTRACT

Acute left colonic diverticulitis (ALCD) is a common clinical condition encountered by physicians in the emergency setting. Clinical presentation of ALCD ranges from uncomplicated acute diverticulitis to diffuse fecal peritonitis. ALCD may be diagnosed based on clinical features alone, but imaging is necessary to differentiate uncomplicated from complicated forms. In fact, computed tomography scan of the abdomen and pelvis is the highest accurate radiological examination for diagnosing ALCD. Treatment depends on the clinical picture, the severity of patient's clinical condition and underlying comorbidities. Over the last few years, diagnosis and treatment algorithms have been debated and are currently evolving. The aim of this narrative review was to consider the main aspects of diagnosis and treatment of ALCD.
