1 · What the graph read from it

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.

2 · The registry

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

backgroundEmergency resection is common for malignant right-sided obstructive colon cancer. As there is evidence showing a potential benefit of self-expandable metal stents as a bridge to surgery, a new debate has been initiated.

objectiveThe aim of this study was to compare self-expandable metal stents with emergency resection in right-sided obstructive colon cancer. DATA SOURCE: A systematic search was conducted accessing Medline/PubMed, Scopus, Embase, and the Cochrane Database of Systematic Reviews. STUDY SELECTION: Studies reporting either emergency surgery or stent placement in right-sided obstructive colon cancer were included.

interventionStent or emergency resection in right-sided obstructive colon cancer.

main outcome measuresMorbidity rate, mortality rate, stoma rate, laparoscopic resection rate, anastomotic insufficiency rate, success rate of stent.

resultsA total of 6343 patients from 16 publications were analyzed. The stent success rate was 0.92 (95% CI, 0.87 to 0.95) with perforation of 0.03 (95% CI, 0.01 to 0.06). Emergency resection was performed laparoscopically at a rate of 0.15 (95% CI, 0.09 to 0.24). Primary anastomosis rate in emergency resection was 0.95 (95% CI, 0.91 to 0.97) with an anastomotic insufficiency rate of 0.07 (95% CI, 0.04 to 0.11). The mortality rate after emergency resection was 0.05 (95% CI, 0.02 to 0.09). Primary anastomosis and anastomotic insufficiency rate were similar between the two groups (RR: 1.02; 95% CI, 0.95 to 1.1; p = 0.56 and RR: 0.53; 95% CI, 0.14 to 1.93; p = 0.33). The mortality rate in emergency resection was higher compared to stent (RR: 0.51, 95% CI 0.30 to 10.89, p = 0.016). LIMITATION: No randomized controlled trials are available.

conclusionStent is a safe and successful alternative to emergency resection and may increase the rate of minimally invasive surgery. Emergency resection, however, remains safe and did not result in higher rate of anastomotic insufficiency. Further high-quality comparative studies are warranted to assess long-term outcomes.
