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.

Abstract

backgroundThe use of a colonic stent as a bridge to surgery aims to provide patients with elective one-stage surgical resection while reducing stoma creation and postoperative complications. This study used meta-analytic techniques to compare the outcomes of stent use as a bridge to surgery and emergency surgery in the management of obstructive colorectal cancer.

methodsA literature search of Medline, Embase, Cochrane controlled trials registry, and the Chinese Biomedical Literature Database was performed on all studies comparing stent as a bridge to surgery and emergency surgery for obstructive colorectal cancer. A meta-analysis of the included studies was carried out to identify the differences in outcomes between the two procedures.

resultsEight studies matched the criteria for inclusion and reported on the outcomes of 601 patients, of whom 232 (38.6%) underwent stent insertion and 369 (61.4%) underwent emergency surgery. Fewer patients in the stent group needed intensive care (risk ratio [RR], 0.42; 95% confidence interval [CI], 0.19-0.93; p = 0.03) and stoma creation (RR, 0.70; 95% CI, 0.50-0.99; p = 0.04). The primary anastomosis rate in the stent group was higher (RR, 1.62; 95% CI, 1.21-2.16; p = 0.001). Overall complications (RR, 0.42; 95% CI, 0.24-0.71; p = 0.001), including anastomotic leakage (RR, 0.31; 95% CI, 0.14-0.69; p = 0.004), were reduced by stent insertion. Stent placement before elective surgery did not adversely affect mortality and long-term survival.

conclusionsThe use of a stent as a bridge to surgery for obstructive left-sided colorectal cancer could increase the chance of primary anastomosis and reduce the need for stoma creation and postprocedural complications. Stent insertion before subsequent surgery has no effect on perioperative mortality and long-term survival.
