The influence of antibiotic and mechanical bowel preparation on the microbiome in colorectal cancer surgery: A pilot 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
Backround: The extent to which bowel preparation mechanical (MBP) or oral antibiotic (OA) or in combination (MBP/OA)) should be performed prior to elective colorectal surgery is the subject of ongoing debate. The aim of our study was to investigate the effect of MPB/OA [with single-shot intravenous antibiotic administration before incision (MPB/OA+ivAB)] on the microbiome of patients with colorectal carcinoma (CRC) operated minimally-invasive. Methods: We were studying 16 consecutive patients who underwent elective resection surgery for CRC at our centre in a prospective panel study. MBP was performed and 1 g parmomomycin/500 mg metronidazole was administered orally one day preoperatively; 1 g ertapenem was administered intravenously 30 min prior incision. Three mucosal samples were taken preoperatively during colonoscopy and intraoperatively and analysed by 16S rRNA V1-V2 gene sequencing. Results: Before MPB/OA+ivOA, the genera Conclusions: In our pilot study, we observed a significant reduction in seven bacterial genera after MBP/OA+ivAB in patients with CRC. Some of these bacterial genera have been associated with anastomotic insufficiency. Further, large in-depth analyses are needed to evaluate perioperative microbial drift with postoperative complications.
