EUS ‐B‐ FNA Enabled Pathological Diagnosis After Airway Stenting due to Severe Stenosis by Adenocarcinoma

Key Result

EUS-B-FNA safely enabled adenocarcinoma diagnosis after airway stenting in a case of severe stenosis, minimizing risks associated with transbronchial biopsy.

Key Points

To highlight the effectiveness of EUS-B-FNA for diagnosing adenocarcinoma after airway stenting.
Patient with severe stenosis and SVC syndrome undergoes urgent Y-stent placement.
EUS-B-FNA performed for diagnosis after stenting.
Comparison made with transbronchial biopsy risks in stenosis.
EUS-B-FNA successfully diagnoses adenocarcinoma.
Transbronchial biopsy associated with high risk of fatal obstruction.
Transesophageal biopsy is suggested as a safer alternative for diagnosis.

Structured PICO

Population

A 49-year-old man with severe airway stenosis and SVC syndrome

Intervention

EUS-B-FNA (endoscopic ultrasound with bronchoscope-guided fine needle aspiration) after urgent Y-stent placement

Outcome

Pathological diagnosis of adenocarcinoma

Transesophageal biopsy (EUS-B-FNA) should be prioritized over transbronchial biopsy in patients with severe airway stenosis to ensure safe diagnosis and avoid fatal obstruction.

Main Result

Absolute Event Rate: 0% vs 0%

Abstract

ABSTRACT A 49‐year‐old man with severe airway stenosis and SVC syndrome underwent urgent Y‐stent placement before diagnosis. Subsequent EUS‐B‐FNA enabled adenocarcinoma diagnosis. This case highlights that transbronchial biopsy in marked stenosis risks fatal obstruction; thus, transesophageal biopsy should be prioritised to ensure safe diagnosis and genomic testing.
