Outcomes of emergency colorectal surgery within a non-colorectal split site service-a retrospective cohort study.
Observational study in Irish journal of medical science, 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
backgroundEmergency colorectal surgery carries a high risk of morbidity and mortality. Subspecialisation and split-site geographically distinct services may lead to critically unwell patients presenting to a non-colorectal specialist centre requiring urgent on-site intervention.
aimsThis study aims to determine outcomes of this high-risk patient cohort.
methodsAn observational retrospective study of emergency colorectal laparotomies at the Royal Infirmary of Edinburgh (RIE) between January 2016 and August 2020 was performed. The primary outcome was 30-day mortality. Secondary outcomes included rate of primary anastomosis, complications and overall mortality. Subgroup analysis of the vascular ischaemia cohort and colorectal surgeon involvement was performed.
resultsOne hundred and eighteen patients were included. The median NELA (National Emergency Laparotomy Audit) score was 6.4% (IQR 2.5%-16.7%) and the 30-day mortality rate was 22% (26/118). The rate of primary anastomosis was 24.6%. Twenty-five patients had a vascular ischaemic pathology demonstrating a higher median NELA score (14.3%, IQR 5-22.4% vs. non-ischaemic group 5.7%, IQR 1.7-14.2%, p = 0.013) and thirty-day mortality (44%, 11/25 vs. 16.1%, 15/93, p = 0.006) than those without ischaemic pathology. Colorectal surgeon involvement in cases without ischaemia (23/93) was associated with a similar 30-day mortality (13.1% colorectal surgeon vs. 17.1% non-colorectal specialist surgeon, p = 0.755) and rate of primary anastomosis (30.4% colorectal surgeon vs. 31.8% non-colorectal specialist surgeon, p = 1).
conclusionsThe high mortality rate described highlights a specific group of unwell patients unfit for transfer. Research registration number: researchregistry7101.
