Autogenic-regenerated intestinal transplantation improves outcomes in short bowel syndrome.
Article in JCI insight, 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
Small bowel transplantation (SBT) is the only curative treatment for intestinal failure due to short bowel syndrome (SBS); however, the 10-year graft survival rate after SBT remains below 50%. Therefore, alternative treatments are required. We developed a potentially new therapeutic strategy for intestinal failure involving in vivo intestinal regeneration using a decellularized scaffold in a rat model. A 3 cm segment of decellularized small intestine was anastomosed to the jejunum for in vivo regeneration. After 4 weeks of regeneration, the entire native intestine was resected to induce SBS, and the regenerated intestine was transplanted into the same rat. Histological analysis revealed regeneration of mucosa, nerves, muscular layer, and crypts, consistent with autologous cell infiltration. An indocyanine green test confirmed blood flow from the adjacent mesentery into the regenerated intestine. The regenerated intestine exhibited absorption of nutrients in vivo, and ex vivo assessments confirmed peristalsis and absorptive capacity comparable with native intestine. Transplantation of the regenerated intestine significantly improved postoperative nutritional status in SBS rats. Our method, autogenic-regenerated intestinal transplantation, showed the therapeutic potential for intestinal failure. This is the first study to our knowledge to demonstrate a functionally integrated regenerated intestine, providing a foundation for future regenerative therapy.
