Laparoscopic Surgery Is Associated With Reduced Small Bowel Obstruction Risk After Colorectal Cancer Surgery: A Nationwide Cohort Study of 5458 Patients.
Article in Annals of gastroenterological 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
Introduction: Postoperative small bowel obstruction (SBO) is a major complication following colorectal cancer surgery, yet evidence-based prevention strategies remain unclear. We aimed to clarify site-specific risk factors for SBO and evaluate the effectiveness of laparoscopic surgery and adhesion prevention materials (APMs) in preventing SBO after colorectal cancer surgery. Methods: This retrospective cohort study analyzed 5458 patients who underwent colorectal cancer surgery at 32 Japanese institutions between 2012 and 2014. The primary endpoint was the 5-year risk of SBO. We evaluated the effects of laparoscopic surgery, APM use, and stoma creation on SBO risk. Clinical variables included demographics, tumor site, operative approach, operative details, and postoperative complications. Hospital-level clustering was addressed using mixed-effects logistic regression. Results: Overall SBO incidence was 5.2% ( Discussion: Laparoscopic surgery was associated with reduced long-term SBO risk, with significant benefits in ascending and sigmoid colon surgery. APMs showed no measurable benefit. Stoma creation increased SBO risk, with no observed difference between ileostomy and colostomy.
