The Application of Dual-Pathway Contrast-Enhanced Ultrasound (CEUS) in the Treatment of Periappendiceal Abscesses.

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
objectivesTo explore the value of an ultrasound contrast agent (Sonovue) as an interventional treatment for periappendiceal abscesses.
methodsFrom January 2019 to December 2020, 30 patients were recruited who were admitted to Jinan Central Hospital due to periappendiceal abscesses. Before the operation, 2.5 ml of SonoVue
resultsAn ultrasound contrast agent was used preoperatively to assess the extent of the abscess. Liquefaction and necrosis were observed in the abscess cavity. CEUS showed hyperenhancement in the wall of the abscess in the arterial phase and the liquefied necrotic area in the abscess cavity was not enhanced before PCD. CEUS allowed operators to confidently identify the puncture site. Amongst the 30 cases of PCD, 27 cases showed the clear positioning of the drainage tube. The head of the drainage tube was placed in the ideal position and development could be seen in the abscess cavity. The diffusion effect of the contrast agent was good with no spillover and the drainage was unobstructed. Abscess development was observed in 3 patients after puncture injection of the contrast agent but the head of the drainage tube was not in the predetermined position. After adjusting the position of the drainage tube, CEUS was repeated and showed a strong diffusion effect of the contrast agent.
conclusionsIntravenous injection of Sonovue before PCD of periappendiceal abscesses can evaluate the extent of the abscess, liquefaction and necrosis in the abscess cavity. The approach can also provide guidance for the placement of the drainage tube. After the operation, a diluted contrast agent was injected through the drainage tube. The position of the drainage tube and the flow direction of the contrast agent could be seen. This approach has good value for clinical applications to accurately judge the position of the drainage tube.
