Utility of Enteral Contrast Protocols in Pediatric Adhesive Small Bowel Obstruction: A Prospective Multicenter Observational Study.
Observational study in Annals of surgery, 2025. 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
objectiveOur objective was to determine the utility of enteral contrast-based protocols in the diagnosis and management of adhesive small bowel obstruction (ASBO) for children.
backgroundEnteral contrast-based protocols for adults with ASBO are associated with a decreased need for surgery and shorter hospitalization. Pediatric-specific data are limited.
methodsWe conducted a prospective observational study between October 2020 and December 2022 at 9 children's hospitals that are members of the Western Pediatric Surgery Research Consortium. Inclusion criteria were children aged 1 to 20 years diagnosed with ASBO who underwent a trial of nonoperative management at hospital admission. Comparisons were made between those children who received an enteral contrast challenge and those who did not. The primary outcome was the need for surgery.
resultsWe enrolled 136 children (71% male; median age: 12 years); 84 (62%) received an enteral contrast challenge. There was no difference in the rate of operative intervention between the no-contrast (34.6%) and contrast groups (36.9%; P =0.93). Eighty-seven (64%) were successfully managed nonoperatively with no difference in median length of stay ( P =0.10) or rate of unplanned readmission ( P =0.14). Among the 49 children who required an operation, there was no significant difference in the time from admission to surgery or rate of small bowel resection based on prior contrast administration.
conclusionsThe addition of enteral contrast-based protocols for the management of pediatric ASBO does not decrease the likelihood of surgery or shorten hospitalization. Larger randomized studies may be needed to further define the role of radiologic contrast in the management of ASBO in children.
