Beyond Obstruction: Evaluating Self-Expandable Metallic Stents (SEMSs) vs. Emergency Surgery for Challenging pT4 Obstructive Colon Cancer: Multicentre Retrospective Study.

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/
objectivesColon cancer presents as an obstruction in almost 30% of patients. Self-expandable metallic stents emerged as an alternative to emergency surgery, despite early controversies around their use. Improved techniques led to stent incorporation in clinical guidelines. Our objective is to compare colectomies performed after the insertion of self-expandable metallic stents versus emergency surgeries in pT4 obstructive left colon cancer, analysing postoperative and oncological outcomes.
methodsThis is an observational retrospective multicentre study involving 50 hospitals and analysing data from patients with pT4 obstructive tumours treated for curative intent between 2015 and 2017. Patients with left-sided obstructive colon cancer were included, with exclusion criteria being palliative surgery or incomplete resection. Primary outcomes were local, peritoneal, and systemic recurrence rates, overall survival (OS), and disease-free survival (DFS). Secondary outcomes were postoperative complications and the rate of surgeries without major complications.
resultsIn total, 196 patients were analysed, 128 undergoing emergency surgery and 68 receiving colonic stents. Stents more frequently allowed for minimally invasive surgeries: 33.8% vs. 4.7% (
conclusionsSelf-expandable metallic stents are a safe alternative for pT4 obstructive left colon cancer, improving postoperative outcomes without compromising short- and medium-term oncological results. Consideration of experienced clinicians and potential referral to centres with advanced stenting capabilities may enhance patient care.
