Impact of a low-cost lamb anus Hirschsprung pull-through surgery model: results from a structured national workshop.
Article in Pediatric surgery international, 2026. 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
purposeA nationwide simulated Hirschsprung's Soave pull-through surgery (HPTS) workshop using a lamb model was set up to train pediatric surgeons. Operative confidence, skills acquisition and clinical application were evaluated.
methodsThe model (< 5 USD) comprised fresh lamb anorectum with terminal perianal muscle and skin preserved and a 20-cm rectum, inserted and fixed onto a mini basket, which allowed dissection using monopolar diathermy. Each trainee performed the five-step Soave procedure twice under supervision. Operative confidence for each step was measured pre- and post-workshop using a 10-point Likert scale, with model realism and utility similarly rated. A 3-6-month follow-up survey assessed clinical translation.
resultsSeventeen participants and 14 trainers from nine centres facilitated completion of 34 simulated procedures. Median overall confidence improved from 2.5 to 7.0 (P < 0.0005), with the greatest gains obtained in submucosal dissection (2.0 to 8.0), cuff management (2.0 to 8.0) and anastomosis (3.0 to 8.0) (all P < 0.001). Model realism and training utility were rated 9/10 and 9/10, respectively, by 25 respondents (93% response rate). Follow-up survey (12/17; 71%) showed 100% agreement that the workshop improved ability to assist or perform HPTS.
conclusionThis structured simulation-based HPTS workshop, using a validated low-cost model, significantly improved procedural confidence which translated into behavioural change in clinical practice. The model offers high fidelity, scalability and ethical training.
