Transforming outcomes: the pivotal role of self-expanding metal stents in right- and left-sided malignant colorectal obstructions-bridge to surgery: a comprehensive review and meta-analysis.
Article in Clinical endoscopy, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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/
aimsSelf-expanding metallic stents (SEMS) are an alternative to emergency surgery (ES) for malignant colorectal obstruction. This study aimed to compare surgical outcomes between SEMS as a bridge to surgery (BTS) and ES in patients with malignant colorectal obstruction.
methodsA comprehensive database search was conducted until October 2023 to compare outcomes between SEMS as a BTS and ES. A subgroup analysis of results by malignancy site was performed.
resultsWe analyzed 57 studies, including 7,223 patients over a mean duration of 35.4 months. SEMS as a BTS showed clinical and technical success rates of 88.0% (95% confidence interval [CI], 86.1%-90.1%; I2=68%) and 91.6% (95% CI, 89.7%-93.7%; I2=66%), respectively. SEMS as a BTS revealed reduced postoperative adverse events (odds ratio [OR], 0.51; 95% CI, 0.41-0.63; I2=70%; p<0.001) and 30-day mortality (OR, 0.52; 95% CI, 0.37-0.72; I2=10%; p<0.001) compared to ES. Subgroup analysis showed postoperative mortality of 5% and 1.5% for left- and right-sided malignancies, respectively. Adverse events were 15% and 33% for the right and left colon, respectively.
conclusionsSEMS as a BTS demonstrated a higher success rate, fewer postoperative adverse events, and a reduced 30-day mortality rate than ES, supporting its use as the preferred initial intervention for right- and left-sided obstructions and indicating broader clinical adoption.
