Targeted nutritional prehabilitation for high-risk Crohn's disease patients undergoing elective gastrointestinal surgery: a case series.
Article in Frontiers in nutrition, 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
Background: Crohn's disease (CD) is a chronic inflammatory bowel condition often leading to complications requiring surgery. Optimizing nutrition before surgery contributes to reducing postoperative complications. The Crohn's Disease Exclusion Diet (CDED), combined with Modulen as partial enteral nutrition (PEN), has been shown to help restore the intestinal barrier, promote a balanced immune response, and mitigate the inflammatory process (Modulen: Nestlé Italia S.p.A: Milan, Italy). Thus, this approach may be implemented into a prehabilitation protocol to tailor nutritional interventions for candidates undergoing CD surgery. Methods: We describe four adult CD patients who underwent preoperative nutritional optimization with CDED+PEN. Interventions lasted 2-12 weeks, providing 30-35 kcal/kg/day, and were tailored based on weight and appetite. Adherence, nutritional markers, medical therapy, and surgical outcomes were monitored. Results: All patients showed good adherence and tolerance to CDED+PEN, with no flare-ups or treatment discontinuations. CDAI decreased in three of four cases. Nutritional status was maintained in all cases. CRP and albumin remained within normal values. Two patients discontinued biologics before surgery without complications, while two were managed without pharmacological therapy. All patients underwent robotic intestinal resection with no postoperative complications. Conclusion: CDED+PEN may be incorporated into the prehabilitation protocol to enhance the nutritional and inflammatory status of CD patients undergoing surgery. Clinical trials assessing its efficacy and tolerance are warranted.
