Clinical Signs as a Guide for Esophagram After Esophageal Atresia/Tracheoesophageal Fistula Repair.
Article in The Journal of surgical research, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
introductionEsophageal atresia/tracheoesophageal fistula (EA/TEF) is a congenital malformation that occurs in about 1 in 2500-4000 live births. After surgical repair, despite the lack of evidence supporting the routine use of postoperative esophagram, most surgeons report obtaining an esophagram prior to enteral feeding. We hypothesized that abnormal indicators in vital signs, drain characteristics, and chest radiograph (CXR) could be used to screen for anastomotic leak, thus reducing the need for a routine esophagram.
methodsA single institution, retrospective chart review of all patients born with EA with or without TEF between 2009 and 2022 was performed. Vital signs, postoperative CXR, chest drain characteristics, and esophagram results were analyzed for patients who underwent repair.
resultsForty-five patients who underwent EA/TEF repair were included in the study, and 40 patients had routine esophagram. Out of the twenty-two patients who had at least one abnormal indicator, 14 (64%) had an anastomotic leak. Seventeen patients (43%) had the absence of abnormalities of all three indicators, and none of these patients had an anastomotic leak (100% negative predictive value). Moreover, changes in drain characteristics and vital signs together presented high sensitivity (87.5%), specificity (90%), and negative predictive value (94%).
conclusionsIn the absence of abnormalities in vital signs, CXR, and drain characteristics in patients undergoing EA/TEF repair, routine esophagram can be safely avoided prior to enteral feeding. Abnormalities in drain characteristics and vital signs together were highly sensitive and specific for anastomotic leak, thus potentially eliminating the need for routine CXR and thereby minimizing radiation exposure and cost.
