Mechanical distraction enterogenesis utilizing springs has equal effectiveness in adult and juvenile pigs.
Article in Pediatric surgery international, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
purposeWe aim to apply our spring-mediated intestinal lengthening technique to adults and children with short bowel syndrome. We hypothesized that spring-mediated intestinal lengthening would be achieved in adult and juvenile pigs.
methodsAdult and juvenile pigs underwent insertion of a compressed spring into the jejunum. Jejunum was plicated proximal and distal to the capsule for fixation and control jejunum was marked. Pigs were fed a liquid diet for one week. Spring and control segment lengths were compared using Brown-Forsythe and Welch ANOVA test.
resultsThree adult pigs weighing 30.4 ± 2.1 kg and three juvenile pigs weighing 8.9 ± 1.2 kg underwent spring insertion without complications. Springs were compressed from 7.5 to 2 cm and had an average spring constant of 9.7 ± 1.2 N/m in adults and 5.4 ± 1.5 N/m in juveniles. Springs of 1.3 cm diameter were implanted in adults and springs of 1.0 cm diameter were implanted in juveniles. Spring segments lengthened on average by 86 ± 33% in adults (p = 0.04) and 123% in juveniles (p < 0.01) when compared to the initial length. There was no statistically significant difference in lengthening between juvenile and adult pigs (p = 0.2).
conclusionIntestinal lengthening was feasible in adult pigs but required a higher force for their larger diameter intestine compared to juvenile pigs.
