Impact of laparoscopic and open surgery on stoma formation and postoperative outcomes in elderly patients with obstructive colorectal cancer following self-expandable metallic stent placement: a systematic review and meta-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
Colorectal cancer (CRC) is a leading cause of cancer-related mortality, particularly in elderly patients. Obstructive CRC, often treated with self-expandable metallic stents (SEMS) as a bridge to surgery, requires careful consideration of the surgical approach. This systematic review and meta-analysis compares laparoscopic surgery (LS) and open surgery (OpS) for managing obstructive CRC in patients aged 65 and older following SEMS placement. This age group is often underexamined in clinical studies, and the existing research frequently includes a heterogeneous mix of age groups, limiting its applicability to elderly populations. A comprehensive literature search was conducted through PubMed, Scopus, and Cochrane Library up to November 2024. Studies comparing LS and OpS outcomes in patients aged 65 and older who had SEMS placement were included. Outcomes, such as anastomotic leakage, ileus, mortality, postoperative complications, anastomosis rates, stoma construction, and wound infections were analyzed. The data from observational studies were synthesized using random-effects models. The meta-analysis of seven studies involving 326 patients (166 in laparoscopic and 160 in OpS) showed no significant differences between the two approaches in most postoperative outcomes. Specifically, for anastomotic leakage (OR = 0.65, 95% CI 0.18-2.28, P = 0.50, I
