The role and value of low-dose computed tomography scan compared to esophagoscopy in the diagnosis of foreign body ingestion in adults.

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
backgroundInformation regarding computed tomography (CT) scan as a first-line screening tool for diagnosis of foreign body (FB) ingestion is limited to a few studies. This study aimed to discuss the role of low-dose CT scan in diagnosing FB ingestion and its complications in adults, along with its diagnostic values compared to X-ray and esophagoscopy. MATERIALS AND
methodsIn this retrospective, cross-sectional study, all hospital records of adult patients diagnosed with foreign body ingestion from March 2014 to February 2019 were reviewed.
resultsAmong a total of 114 patients, 41 (36.0%) and 86 patients (85.1%) had positive findings in favor of FB in chest radiographs and CT scans, respectively. Esophagoscopy showed the presence of a foreign body in a total of 95 (83.3%) cases, perforation in 14 cases (12.3%), and laceration in nine cases (7.9%). Also, 12 patients (10.5%) had no findings in their esophagoscopy. The sensitivity, specificity, positive predictive value, and negative predictive value of chest X-ray were 39.2%, 91.7%, 97.6%, and 15.1%, respectively. The sensitivity and specificity of CT were reported to be 96.62% and 100%, respectively. The positive predictive value of the CT method was 100%, and its negative predictive value was 80.0%.
conclusionCT scan can be the preliminary tool for the diagnosis of FB ingestion. It can decrease hospital stay and hospital costs by avoiding unnecessary endoscopy. Due to the insufficiency of X-ray, low-dose CT can be used as a first-line diagnostic tool, especially in cases with ingestion of radiolucent FBs.
