After stent placement in patient with left colon cancer with intestinal obstruction safety and efficacy analysis.
Article in Journal of cancer research and clinical oncology, 2025. 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
purposeThis study aimed to evaluate the safety and efficacy of intestinal stent placement as a bridge to surgery in patients with left colon cancer complicated by intestinal obstruction (LCCO).
methodsA retrospective cohort analysis was conducted on 111 patients diagnosed with LCCO at The Second Affiliated Hospital of Chongqing Medical University between January 2015 and August 2019. Patients were divided into two groups: the stent group (SG, n = 41) and the emergency surgery group (EG, n = 70). Primary endpoints included 3-year progression-free survival (PFS), local recurrence, and distant metastasis rates. Secondary endpoints encompassed 3-year overall survival (OS), intraoperative parameters (lymph node dissection, blood loss, operative time), enterostomy rate, postoperative complications, and hospital stay duration.
resultsNo significant differences were observed between SG and EG in 3-year PFS (59% vs. 41%, P = 0.091), OS (61% vs. 44%, P = 0.051), or metastasis rates (19.5% vs. 20%, P = 0.95). However, SG demonstrated superior short-term outcomes, including reduced intraoperative blood loss (60 mL vs. 78 mL, P = 0.02), shorter hospital stay (10.2 vs. 16.1 days, P < 0.001), lower enterostomy rate (0% vs. 100%, P < 0.001), and fewer postoperative complications (14.6% vs. 24.3%, P = 0.012).
conclusionStenting in patients with left colon cancer with obstruction can relieve the symptoms of intestinal obstruction in time. Compared with emergency open surgery, it has better short-term results and does not affect the long-term curative effect of the tumor.
