Diagnostic value of endoscopic ultrasonography in periampullary duodenal tumours.

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
Introduction: The objective of this study was to investigate the diagnostic value of endoscopic ultrasonography (EUS) for tumours around the duodenal ampullary. Patients and Methods: A retrospective analysis was performed on cases diagnosed and treated in our hospital from October 2016 to August 2021 due to the lesions around the duodenal ampulla. All patients received EUS, abdominal enhanced computed tomography (CT) and magnetic resonance imaging combined with magnetic resonance cholangiopancreatography (MRI-MRCP). Pathological diagnosis was used to verify the accuracy of the imaging findings. The detection rates of periampullary tumours by EUS, abdominal enhanced CT and MRI-MRCP were determined and compared. Results: A total of 86 patients were included in this study. According to the pathological diagnosis, the detection rate of EUS was 87% (36/41) for periampullary tumour lesions with a tumour diameter <1 cm, which was significantly higher than that of MRI-MRCP (59%, 24/41) (P = 0.003) and CT (44%, 18/41) (P < 0.001). For periampullary tumour lesions with a tumour diameter ≥1 cm, the detection rate of MRI-MRCP was 93% (42/45), which was significantly higher than that of EUS (78%, 35/45) (P = 0.036) and CT (76%, 34/45) (P = 0.02). Conclusions: EUS can accurately detect tumour lesions around the ampullary part of the duodenum with minimal gas interference. For periampullary tumour lesions <1 cm, EUS has better diagnostic accuracy than abdominal-enhanced CT and MRI-MRCP. In addition, a biopsy of the lesion can be performed at the same time during the EUS examination. Therefore, EUS has an important clinical significance and value in the diagnosis of duodenal periampullary tumours.
