Polyglycolic acid-cyanoacrylate complex for prevention of major intestinal anastomotic leakage in a rat model: an experimental animal study.

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
Purpose: Various materials and techniques have been explored to prevent anastomotic leakage (AL). Polyglycolic acid (PGA) sheets and cyanoacrylate (CA) glue have been investigated for their potential in wound healing and fistula closure. This study aims to assess the feasibility of PGA-CA complex (PCC) to prevent AL by developing a major leakage model in rats. Methods: After the creation of the major leakage model in the jejunum of rat, the leakage site was treated with each material individually and in combination. Rats were categorized into the control, CA, PGA, and PCC groups. Results: A total of 40 rats were included, with one animal from the CA and PGA groups having expired. Gross intra-abdominal conditions showed no significant difference between the groups. Median intraluminal bursting pressure was 120.0 (range, 102.5-138.0) in the CA group and 138.0 (range, 127.0-147.0) in the PCC group (P = 0.286). Pathologic evaluation revealed fibroblast activation was significantly different in the PCC group (P = 0.025). Conclusion: No significant differences were observed in the macroscopic intra-abdominal findings or intraluminal bursting pressure between the groups. The only difference in PCC group was enhanced fibroblast activation at moderate levels compare to the control group. Further research is warranted to optimize material combinations and validate efficacy in larger preclinical and clinical settings.
