INTRODUCTION: The current surgical management of acute complicated diverticulitis has seen a major paradigm shift from routine operative intervention to a more conservative approach. This has been made possible by the widespread availability of computed tomography (CT) to enable stratification of the disease severity of acute complicated diverticulitis. The aim of this study was to retrospectively validate a CT grading system for acute complicated diverticulitis in the prediction of the need for operative or percutaneous intervention.
METHODS: Hospital and radiology records were reviewed to identify patients with acute complicated diverticulitis confirmed by CT. A consultant gastrointestinal radiologist, blinded to the clinical outcomes of patients, assigned a score according to the CT grading system.
RESULTS: Three hundred and sixty-seven patients (34.6%) had CT performed for acute diverticulitis during the study period. Forty-four patients (12.0%) had acute complicated diverticulitis (abscess and/or free intraperitoneal air) confirmed on CT. There were 22 women (50%) and the overall median age was 59 years (range: 19-92 years). According to the CT findings, there was one case with grade 1, eighteen patients with grade 2, four with grade 3 and twenty-one with grade 4 diverticulitis. Three patients with grade 2, three patients with grade 3 and ten patients with grade 4 disease underwent acute radiological or surgical intervention.
CONCLUSIONS: The use of a CT grading system for acute complicated diverticulitis did not predict the need for acute radiological or operative intervention in this small study. Decision making guided by the patient's clinical condition still retains a primary role in the management of acute complicated diverticulitis.
