Palliative resection versus palliative stenting for intestinal obstruction in patients with metastatic left-sided colonic cancer: a propensity score-matched analysis.

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
purposePalliative resection and palliative stenting are established options for managing obstruction in patients with metastatic left-sided colonic cancer. This retrospective study investigated the long-term outcomes and survival associated with each treatment modality.
methodsPatients with left-sided colon cancer complicated by intestinal obstruction and unresectable metastatic lesions were included. Propensity score matching was conducted to balance demographic characteristics. The primary outcome was long-term survival. Secondary outcomes included short-term morbidity, length of hospital stay, clinical success rate, stoma formation rate, and number of readmissions due to tumor-related complications.
resultsInitially, 131 patients who underwent palliative resection or stenting between 2015 and 2022 were included. After propensity score matching, 98 patients remained (49 in each group). Survival was significantly better among patients receiving palliative resection compared to stenting (median, 19.6 months vs. 9.6 months; P=0.003). However, subgroup analysis for patients older than 70 years demonstrated no statistically significant survival benefit (median, 11.5 months vs. 10.2 months; P=0.240). The resection group experienced significantly higher rates of stoma formation and longer postoperative hospital stays. Readmission rates were similar. Cox regression analysis identified low carcinoembryonic antigen levels, tumor resection, chemotherapy, and targeted therapy as independent predictors of longer survival.
conclusionFor metastatic colon cancer patients presenting with intestinal obstruction, palliative resection may offer a survival advantage. However, this benefit diminishes in patients over 70 years of age. Additionally, resection is associated with a higher rate of stoma formation. Therefore, individualized treatment decisions are warranted when choosing between palliative resection and palliative stenting in metastatic colonic cancer patients.
