Thoracoscopic management of easily neglected extralobar pulmonary sequestration presenting with torsion and infarction in children: three case reports and literature review.

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
Background: Extralobar pulmonary sequestration (ELS) is a rare congenital pulmonary malformation, and reports of ELS complicated by torsion and infarction are exceedingly uncommon. Here, we report three pediatric cases of ELS complicated by torsion and infarction, aiming to enhance clinical awareness and understanding of this condition. Methods: Using the keywords "extralobar pulmonary sequestration, torsion, infarction, thoracoscopic, chest pain, abdominal pain, children", we conducted a comprehensive literature review of all studies related to ELS with torsion in children from database inception to December 2025. We identified 16 articles describing ELS with torsion, comprising a total of 24 reported pediatric cases of pulmonary sequestration complicated by torsion. Results: Between May 2022 and November 2025, three children with ELS complicated by torsion and infarction were treated at Shanghai Children's Hospital. Two patients presented primarily with abdominal pain and chest pain, while one patient presented with abdominal pain alone. Contrast-enhanced chest computed tomography (CT) was performed in all cases: two patients were suspected of having intrathoracic soft-tissue masses, and one patient was diagnosed with pulmonary sequestration. All patients subsequently underwent thoracoscopic resection of the pulmonary sequestration. Postoperative pathological examination confirmed pulmonary sequestration with hemorrhagic necrosis in all three cases. Conclusions: Pulmonary sequestration with torsion should be considered in the differential diagnosis of patients presenting with chest/abdominal pain accompanied by an intrathoracic soft-tissue mass. With the continuous advancement of minimally invasive techniques, thoracoscopic surgery offers a favorable prognosis for pediatric patients with pulmonary sequestration complicated by torsion and infarction.
