Right upper lobectomy via selective right upper lobe isolation using a left-sided double-lumen tube placed in the right bronchus intermedius: a case report.
Article in BMC surgery, 2026. 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
backgroundOne-lung ventilation (OLV) using a left-sided double-lumen tube (DLT) in the left main bronchus is standard for right thoracic surgery. When the contralateral left lung is severely compromised, this approach forces OLV to rely on the dysfunctional lung and risks critical hypoxemia. CASE PRESENTATION: An 84-year-old woman with a left diaphragmatic hernia causing approximately 70% compression and atelectasis of the left lung was scheduled for right upper lobectomy. Preoperative assessment indicated that standard DLT placement would necessitate complete right lung collapse, placing the patient at risk of life-threatening hypoxemia. A 32-Fr left-sided DLT was intentionally inserted into the right bronchus intermedius under fiberoptic bronchoscopy (FOB). The bronchial cuff was positioned at the orifice of the right upper lobe (RUL) bronchus to achieve selective occlusion. Ventilation was delivered through the tracheal lumen to the left lung and through the bronchial lumen to the right middle and lower lobes. The RUL collapsed completely. Intraoperative oxygenation remained stable, with SpO
conclusionsIntentional placement of a left-sided DLT into the right bronchus intermedius is a feasible strategy for selective RUL isolation when standard OLV is contraindicated due to severe contralateral lung compromise. Preoperative computed tomography (CT)-based airway assessment and fiberoptic bronchoscopic guidance are recommended for safe implementation.
