When is the optimal diagnostic biopsy timing of acetylcholinesterase staining in Hirschsprung disease?
Article in BMC pediatrics, 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
purposesThe preoperative diagnosis of Hirschsprung disease (HD) requires a rectal mucosal biopsy and acetylcholinesterase (AchE) staining. However, the optimal timing for performing these procedures remains unclear. In this study, we assessed the most effective timing for a rectal biopsy and AchE staining to diagnose HD.
methodsWe retrospectively collected data from 57 patients who underwent radical surgery for HD at Mie University Hospital between January 2008 and April 2024. We reviewed all rectal biopsies, including those with multiple samples, and analyzed the biopsy date and the results of AchE staining (positive or negative).
resultsAmong the 57 children with a confirmed HD diagnosis, 36 were included in the study. Fifty-two rectal biopsy sessions were performed in these 36 patients with HD, including 15 with multiple biopsies. A receiver operating characteristic analysis showed that the optimal age for diagnosing HD was older than 21 days. Biopsies performed at ≤ 3 weeks of age had a low diagnostic accuracy rate of 30.8%, whereas rectal biopsies performed at > 3 weeks of age showed a high positive diagnostic rate of 87.5%.
conclusionsRectal mucosal biopsies performed after 3 weeks of age show a higher diagnostic accuracy for HD. CLINICAL TRIAL NUMBER: Not applicable.
