Risk factors for non-reversal of diverting ileostomies: a retrospective analysis of 456 patients.
Article in International journal of colorectal disease, 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
purposeDiverting ileostomies are routinely created during low rectal cancer surgery, yet 15-30% remain permanent. Understanding predictors of non-reversal is essential for informed patient counseling. This study investigated factors preventing ileostomy closure following colorectal surgery, primarily for rectal malignancy.
methodsThis retrospective cohort study analyzed prospectively collected data from patients undergoing diverting ileostomy creation (January 2015-December 2020). Exclusions included early postoperative mortality (within 30 days), follow-up less than 6 months, or missing primary outcome data. Demographics, surgical details, and reversal outcomes were analyzed. Multivariable logistic regression identified independent predictors of non-reversal.
resultsOf 508 patients, 456 met inclusion criteria (mean age 58.9 ± 13.2 years, 63.8% male). Malignancy accounted for 96.7% of cases, with low anterior resection performed in 83.8%. Ileostomy closure was achieved in 364 patients (79.8%) at a median of 6 months (mean 7.4 ± 5.3). The non-reversal rate was 20.2% (92 patients). Main reasons included mortality (35.8%), metastatic disease (23.9%), and anastomotic complications (22.8%). Multivariable analysis identified ASA score 3-4 (OR 2.68, 95% CI 1.58-4.54, p < 0.001) and malignant pathology (OR 5.12, 95% CI 1.23-21.3, p = 0.025) as independent predictors of non-reversal. Age showed statistical but limited clinical significance.
conclusionOne in five patients with diverting ileostomies will not undergo reversal. High ASA scores, malignant disease, mortality, metastatic progression, and anastomotic complications are primary barriers. These findings emphasize the need for realistic preoperative counseling regarding permanent stoma risk.
