Anastomotic leakage prevention using dry-preserved fibroblast cell sheets in esophageal reconstruction.
Article in Regenerative therapy, 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
Background: Anastomotic leakage is a common and serious complication of esophageal reconstruction, and new methods are required for its prevention in clinical settings. We herein developed dry-preserved fibroblast cell sheets (dry sheets), which are easy to use and promote wound healing. This study aimed to investigate the efficacy of transplanting allogeneic dry sheets in preventing anastomotic leakage in a rat esophageal reconstruction model. Methods: Allogeneic dry sheets were prepared from the rat oral mucosa. A rat esophageal anastomosis model was created, and two dry sheets were applied to cover the anastomotic sites. Anastomotic leakage incidence, burst pressure, histological findings, and collagen contents were compared between the control and dry sheet groups postoperatively. Results: The dry sheet group demonstrated a lower incidence of anastomotic leakage than the control group (control: 64 % vs. dry sheet: 28 % on day 3, control: 57 % vs. dry sheet: 29 % on day 5). Abscess scores at the esophageal anastomotic sites were also lower in the dry sheet group than in the control group on days 3 and 5. Burst pressure was significantly higher in the dry sheet group than in the control group on days 3 and 5. Collagen type I was significantly increased in the dry sheet group compared with that in the control group. Conclusions: Allogeneic dry sheet application improved anastomotic leakage incidence and burst pressure, indicating the usefulness of these sheets in preventing esophageal anastomotic leakage.
