Clinical impact of diverting ileostomy and high-output stoma on adjuvant chemotherapy for rectal cancer: a retrospective cohort 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
purposeDiverting ileostomy (DI) may cause fluid and electrolyte loss, potentially impairing the tolerability of adjuvant chemotherapy (ACT) in patients with rectal cancer. However, its clinical impact, especially in the presence of high-output stoma (HOS), remains unclear. This study aimed to evaluate the effects of DI and perioperative HOS on chemotherapy completion, dose intensity, and the incidence of severe adverse events (AEs).
methodsWe retrospectively analyzed 107 patients with rectal cancer who underwent curative resection and received postoperative ACT between June 2012 and December 2024 at Tottori University. Chemotherapy completion, relative dose intensity (RDI), and grade ≥ 3 AEs were compared between patients with and without DI. A subgroup analysis assessed the influence of HOS among DI patients.
resultsChemotherapy completion rate and RDI were comparable between patients with and without DI. However, the incidence of grade ≥ 3 AEs was significantly higher in the DI group than in the non-DI group (18.2% vs. 4.1%, P = 0.015), and DI was identified as an independent risk factor in multivariate analysis (odds ratio [OR] 5.749, P = 0.022). Among patients with DI, those with HOS had a significantly lower oxaliplatin RDI than those without HOS (37.5% vs. 75.0%, P = 0.007), and HOS independently predicted failure to complete oxaliplatin-based regimens (OR 13.423, P = 0.039).
conclusionsWhile DI does not impair overall chemotherapy delivery, it is associated with increased early toxicity. HOS may compromise oxaliplatin administration and should prompt early recognition and targeted supportive interventions.
