PurposeTo compare the findings at US, CT and contrast enema (CE) with the clinical, biochemical, and surgical findings in patients with suspected acute left-sided colonic diverticulitis (ALCD).Material And MethodsThe study comprised 32 consecutive patients hospitalized with clinically diagnosed ALCD. During the first 3 days of hospitalization, they were examined by US and CT of the pelvis and abdomen, and CE.ResultsOf the 32 patients, 21 had ALCD according to the combined radiological, clinical, biochemical and surgical findings. Findings compatible with ALCD were verified by radiological examination alone in 12 patients (4 patients at US, 10 at CT, and 6 at CE). In 9 patients, only diverticula or tethering was found at either CE or CT, and the diagnoses were then supported by clinical and biochemical findings and clinical follow-up. The most common clinical symptoms and signs associated with ALCD were left lower quadrant pain, left-sided tenderness, and fever. Most patients showed elevations of the white blood-cell count, erythrocyte sedimentation rate, and C-reactive protein, but there was no statistical difference in the stages of severity of ALCD, or between ALCD and other abdominal disorders.ConclusionRadiological examination is valuable in confirming the diagnosis of ALCD. CT was the radiological modality that best demonstrated ALCD and revealed complications (e.g. pericolic abscesses) during the course of the illness.
