Direct comparison of simultaneous and sequential endoscopic metallic bilateral stenting in malignant hilar biliary obstruction.

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
backgroundEndoscopic bilateral biliary drainage is a first line palliative treatment for unresectable malignant hilar biliary obstruction (MHBO) but remains technically challenging. The emergence of self-expandable metallic stents carried by an ultra-thin (6 Fr or smaller) delivery system now permits simultaneous bilateral stent placement. To date, only a few studies have compared this new method with conventional sequential bilateral stenting.
aimTo evaluate a possible superiority of simultaneous "side by side" (SBS) biliary drainage in unresectable MHBO.
methodsWe identified 135 patients who benefited from bilateral drainage using uncovered self-expandable metallic stents between 2010 and 2023. Among them, 62 benefited from simultaneous SBS bilateral drainage between 2017 and 2023, and 73 benefited from sequential bilateral drainage [38 using "stent in stent" (SIS) technique and 35 using SBS technique between 2010 and 2017].
resultsTechnical success was significantly increased in simultaneous drainage compared with sequential drainage (94%
conclusionSimultaneous SBS metallic stent placement using an ultra-thin delivery system was technically easier and as efficient as sequential bilateral stenting in unresectable MHBO to achieve bilateral drainage. The SIS procedure remains a good option in unresectable MHBO.
