Patients with computed tomography-proven acute diverticulitis require follow-up to exclude colorectal cancer.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
BACKGROUND/
aimsTraditionally, patients with acute diverticulitis undergo follow-up endoscopy to exclude colorectal cancer (CRC). However, its usefulness has been debated in this era of high-resolution computed tomography (CT) diagnosis. We assessed the frequency and outcome of endoscopic follow-up for patients with CT-proven acute diverticulitis, according to the confidence in the CT diagnosis.
methodsRecords of patients with CT-proven acute diverticulitis between October 2007 and March 2014 at Sandwell & West Birmingham Hospitals NHS Trust were retrieved. The National Cancer Registry confirmed the cases of CRC. Endoscopy quality indicators were compared between these patients and other patients undergoing the same endoscopic examination over the same period.
resultsWe identified 235 patients with CT-proven acute diverticulitis, of which, 187 were managed conservatively. The CT report was confident of the diagnosis of acute diverticulitis in 75% cases. Five of the 235 patients were subsequently diagnosed with CRC (2.1%). Three cases of CRC were detected in the 187 patients managed conservatively (1.6%). Forty-eight percent of the conservatively managed patients underwent follow-up endoscopy; one case of CRC was identified. Endoscopies were often incomplete and caused more discomfort for patients with diverticulitis compared with controls.
conclusionsCRC was diagnosed in patients with CT-proven diverticulitis at a higher rate than in screened asymptomatic populations, necessitating follow-up. CT reports contained statements regarding diagnostic uncertainty in 25% cases, associated with an increased risk of CRC. Follow-up endoscopy in patients with CT-proven diverticulitis is associated with increased discomfort and high rates of incompletion. The use of other follow-up modalities should be considered.
