Fatal air embolism during intestinal endoscopy in Kasai portoenterostomy for biliary atresia: A case report.
Article in World journal of gastrointestinal endoscopy, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundAir embolism (AE) is a rare but potentially fatal complication of intestinal endoscopy (IE). CASE SUMMARY: Herein, we report the case of an 18-year-old woman who underwent a successful Kasai portoenterostomy (KPE) for biliary atresia but died of AE during intraoperative IE for stone removal at the portoenterostomy site. Our review of the English literature identified only four similar cases of fatal AE during IE in patients undergoing KPE. The common clinical setting in the five patients, including our case, was high-pressure air insufflation into the blind closed afferent loop of the KPE to secure visibility. We hypothesize that the highly pressurized air injected into the closed loop entered the bile canaliculi-previously opened by KPE for bile drainage-passed through the tiny, microscopic pores of the fenestrated liver sinusoid endothelial cells, and finally entered the bloodstream with ease, resulting in fatal AE.
conclusionMeticulous performance of IE, especially on the KPE blind loop, is warranted owing to the risk of AE.
