Association between ERAS compliance and postoperative outcomes after right colectomy for colon cancer: a single-center cohort study.
Article in BMC surgery, 2026. 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
backgroundEnhanced Recovery After Surgery (ERAS) protocols improve perioperative care in colorectal surgery; however, evidence specifically linking ERAS compliance to outcomes after right colectomy is limited. This study aimed to evaluate the association between overall and phase-specific ERAS compliance and postoperative outcomes after elective right colectomy for colon cancer.
methodsThis retrospective analysis of a prospectively maintained institutional ERAS database included consecutive adults who underwent elective standard or extended right colectomy for colon cancer between January 2021 and December 2025. Compliance was assessed at the patient level using 24 predefined ERAS elements across pre-admission, preoperative, intraoperative, and postoperative phases. The primary outcome was length of stay (LOS), and the secondary outcome was major postoperative complications (Clavien-Dindo grade ≥IIIa). Correlation analyses, group comparisons using a prespecified 75% overall compliance threshold, and multivariable logistic and linear regression analyses were performed.
resultsAmong 151 included patients, 76 (50.3%) developed any postoperative complication, 14 (9.3%) had major postoperative complications, and 10 (6.6%) were readmitted within 30 days. Overall ERAS compliance was inversely correlated with LOS (ρ = -0.329, p < 0.001). Preoperative (ρ = -0.248, p = 0.002) and postoperative (ρ = -0.301, p < 0.001) phase-specific compliance were also associated with shorter LOS. Patients with overall compliance ≥ 75% had shorter LOS than those with lower compliance, whereas major complication rates were similar. In exploratory multivariable analysis, higher preoperative compliance was independently associated with lower odds of major postoperative complications (OR 0.936, 95% CI 0.884-0.991; p = 0.024). Older age (B = 0.183, p = 0.022) and lower overall compliance (B = -0.265, p = 0.006) were independently associated with longer LOS.
conclusionsHigher ERAS compliance was associated with shorter length of stay, though the contribution of postoperative compliance may partly reflect recovery status rather than an independent causal effect. Higher preoperative adherence was independently associated with lower odds of major complications in exploratory multivariable analysis. These findings support strengthening preoperative optimization and consistent pathway execution to improve recovery after right colectomy.
