Implementation of intraoperative procedures to prevent anastomotic leak in low anterior rectal resections: a pilot study for a novel technique to evaluate anastomotic vascularization.
Article in Surgical endoscopy, 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
introductionAltered vascular microcirculation is recognized as a risk factor for anastomotic leakage (AL) in colorectal surgery. However, few studies evaluated its impact on AL using different devices, with heterogeneous results. The present study reported the initial experience measuring gut microcirculatory density and flow with the aid of incidence dark-field (IDF) videomicroscopy (Cytocam, Braedius, Amsterdam, The Netherlands) comparing its operative outcome using a propensity score matching (PSM) model based on age, gender, and Charlson Comorbidity Index (CCI). MATERIALS AND
methodsVideos from 5 different sites (at least 10 s/site) were recorded from both the mucosal and serosal site of the left colon end after the colonic resection. Total vessel density (TVD), Perfused Vessel Density (PVD), De Backer score, Proportion of Perfused Vessels (PPV), and Microvascular Flow Index (MFI) were analyzed. At each recording, noninvasive measurements of blood pressure, heart rate, temperature, use of vasoactive drugs, and peripheral oxygen saturation were simultaneously recorded. The association between postoperative outcomes and microcirculation evaluation was investigated using PSM analyses.
resultsNinety-nine patients were included in the Cytocam group. The mean TVD small was 8.9 ± 2.8 mm/mm
conclusionThis type of anastomotic evaluation has shown to be feasible, safe, and useful in easily detecting any alteration of the resected colon before anastomotic construction. Moreover, this technology could offer a more cost-effective manner than other devices.
