Intestinal microbiota characteristics and dietary fiber intervention in patients undergoing endoscopic mucosa resection.

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
backgroundEndoscopic mucosa resection (EMR) is an important minimally invasive surgical method for treating early digestive tract tumors. In recent years, the crucial role of intestinal microbiota in disease occurrence and development has attracted increasing attention. However, the changes in intestinal microbiota after EMR and the effect of dietary fiber intervention on microbiota recovery remain insufficiently elucidated.
aimTo investigate the effects of dietary fiber intervention on intestinal microbiota recovery in patients undergoing EMR and evaluate its potential to improve postoperative outcomes and intestinal microecological balance.
methodsThis retrospective study analyzed intestinal microbiota sequencing and dietary fiber intervention in patients with EMR. Patients who underwent EMR surgery between 2020 and 2023 were selected and divided into a routine follow-up group and a dietary fiber intervention group. High-throughput 16S rRNA gene sequencing was performed to detect changes in patient intestinal microbiota, and microbiota diversity, structure, and function in different intervention groups were compared and analyzed.
resultsA total of 86 patients with EMR were included in the study. Results showed that: (1) Intestinal microbiota diversity significantly decreased after EMR surgery, with notable changes in the proportion of Gram-negative bacilli and anaerobic bacteria; (2) The microbiota recovery rate in the dietary fiber intervention group was significantly higher than that in the control group, with a significantly higher microbiota diversity index (
conclusionDietary fiber intervention can effectively promote intestinal microbiota recovery in patients with EMR, improve intestinal microecological balance, and provide a new intervention strategy for clinical post-EMR patient rehabilitation.
