Predictive Value of Endobronchial Sonographic Patterns in Diagnosis of Mediastinal Lymphadenopathy (EBUS)

March 14, 2026 updated by: Ain Shams University
This study aims to assess the value of endosonographic patterns of EBUS bronchoscopy in diagnosis of patients with mediastinal lymphadenopathy and correlate it with the histopathological diagnosis.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Detailed Description

All patients will undergo EBUS-bronchoscopy using 22-gauge needle of EBUS.

  • Lymph node stations and numbers were determined according to the International Association for the Study of Lung Cancer classification.
  • Systemic evaluation of Lymph nodes according to ERS guidelines starting with any potential N3 lymph nodes followed by N2 lymph nodes, and N1 lymph nodes Ultrasound features of suspected lymph nodes were categorized according to: B-mode, Color Power Doppler Index (CPDI) After evaluation of ultrasound features, a TBNA using a 22- G needle were performed. Three samples were taken from each node or lesion for +/- rapid on-site evaluation ROSE (using Haematoxylin and Eosin stain) and histopathological examination.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

Sampling Method

Non-Probability Sample

Study Population

A prospective study comprising 50 cases patients who were admitted to bronchoscopy unit of Chest Department at Ain Shams University Hospitals with undiagnosed mediastinal lymphadenopathy.

Description

Inclusion Criteria:

  • Age ≥ 18 years.
  • patients who underwent chest enhanced CT before EBUS-TBNA examination to assess the nature of mediastinal and hilar enlarged lymph nodes.

Exclusion Criteria:

  • Contraindication to needle biopsy (e.g. use of anticoagulation drugs, bleeding diathesis).
  • Patients unfit for bronchoscopy and general anaesthesia by international guidelines.
  • Lymph Nodes that are not accessible or technically difficult by EBUS-TBNA e.g. Station 5,6.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
1- evaluate the morphological characteristics of mediastinal LNs in real time 2- assess the nature of LNs before puncturing either benign or malignant using EBUS and corelate them with the histopathological outcome.
Time Frame: 2 years
  1. EBUS sonographic features can guide the selection of LNs for biopsy
  2. EBUS sonographic features can guide internal puncture site within the LN and biopsy efficiency as a complementary diagnostic value.
2 years

Study Major Dates

Study Start (Actual)

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
May 30, 2024

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
