Usefulness of Novel Balloon-Less Convex Probe Bronchoscope for Diagnosing and Staging of Lung Cancer via EBUS-TBNA and EUS-B-FNA.

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
In the winter of 2025, a novel balloon-less convex-probe endobronchial ultrasound bronchoscope (BLCP-EBUS) (Fujifilm EB-710US) was introduced in Japan. It features a balloon-less design, flexible distal tip, improved angulation, and reduced outer diameter, though clinical experience remains limited. Here we report our initial experience using the EB-710US for EBUS-guided transbronchial needle aspiration (EBUS-TBNA) and endoscopic ultrasound-guided fine-needle aspiration via the bronchus (EUS-B-FNA). An 86-year-old man with mediastinal lymphadenopathy underwent EBUS-TBNA of a left lower paratracheal lymph node (station #4L). Adequate lesion contact and stable needle aspiration were achieved without a balloon, enabling successful tissue collection and adenocarcinoma diagnosis. A 73-year-old man required a re-biopsy for a multiplex driver mutation test, and EUS-B-FNA of lymph node #8 was performed using a novel bronchoscope. Both procedures were safely completed under conscious sedation, with positive rapid on-site cytology evaluation and sufficient tissue for adenocarcinoma diagnosis. The novel BLCP-EBUS bronchoscope (EB-710US) demonstrated favourable manoeuvrability and adequate lesion contact for both EBUS-TBNA and EUS-B-FNA. The novel bronchoscope may enhance procedural safety, patient comfort, and diagnostic yield.
