Analysis of gas embolism in pediatric laparoscopy: incidence, risk factors, and preventive strategies.
Observational study in Surgical endoscopy, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundGas embolism during pediatric laparoscopic surgery is often subclinical but can have serious consequences. Identifying patient and procedure-related risk factors is essential to improve perioperative safety and outcomes. PURPOSE: This study aimed to determine risk factors associated with gas embolism in pediatric laparoscopy and to propose preventive strategies. STUDY
designSingle-center, prospective observational study including 57 pediatric patients undergoing minimally invasive surgery (MIS) from January 2021 to June 2025. Intraoperative gas embolism was monitored by transthoracic echocardiography. Patient demographics, laparoscopic preset, CO₂ volume used, and intra-abdominal pressure (IAP) variations were analyzed as potential risk factors.
resultsGas embolism was detected in 25 patients (43.9%; 95% CI 31.0-56.7%). Patient characteristics and laparoscopic setting parameters were not associated with gas embolism. Repetitive intra-abdominal volume variations were strongly associated with the occurrence of gas embolism (OR 49.8, 95% CI 9.14-271.65; p < 0.0001). The median CO₂ volume was higher in the embolism group (28 vs. 20 L, p = 0.002).
conclusionsGas embolism is common in pediatric laparoscopy, although most episodes are subclinical. Repetitive intra-abdominal pressure variations, which lead to higher CO₂ consumption, significantly increase gas embolism risk. Awareness and careful intraoperative management are essential, particularly in high-risk procedures, to minimize potential complications. These findings support future multi-center studies to validate preventive strategies.
