The Use and Effectiveness of Balloon for Endobronchial Ultrasonography

February 10, 2022 updated by: Centre hospitalier de l'Université de Montréal (CHUM)

Randomized Control Trial of the Use and Effectiveness of Balloon for Endobronchial Ultrasonography.

Although balloons appear to improve ultrasound image quality, it's use can be technically difficult for segmental airways because of anatomical limitations to convex probe imaging. Furthermore, it is uncertain whether this leads to a better diagnostic yield. To our knowledge, there are currently no studies showing that the use of balloon improves diagnostic yield with EBUS. We hypothesize that the use of balloon may increase the diagnostic yield by improving ultrasound image quality and reduce the duration of the procedure.The aim of this study is to analyse whether the use of balloon during linear EBUS 1) improves diagnostic yield, 2) reduces the duration of the procedure, and 3) improves ultrasound image quality with increased operator satisfaction in terms of ease of procedure.

Design Details

  • Primary Purpose: DIAGNOSTIC
  • Allocation: RANDOMIZED
  • Interventional Model: SINGLE_GROUP
  • Masking: NONE

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
EXPERIMENTAL: Endobronchial biopsy with the use of a balloon attached to the echo-bronchoscope
Diagnostic test: Endobronchial biopsy with the use of a balloon attached to the echo-bronchoscope
A small balloon made of latex can be attached to the tip of echo-bronchoscope which is then inflated with water or saline for better apposition of the echo-endoscope and the airway wall. This may improve ultrasound image quality and aid better visualization of the lymph nodes.
NO_INTERVENTION: Endobronchial biopsy without the use of a balloon attached to the echo-bronchoscope

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Diagnostic yield
Time Frame: 1 year
Diagnostic yield will be calculated separately for each group with and without the use of balloon. Diagnostic yield will be defined as a satisfactory sample with presence of lymphocytes in the aspirate on the final pathology report. In order to minimise the confounding factor in diagnostic yield based on the dimensions of the LN, we chose a single LN station (4R) and patients were sub-dvided into 3 groups based on the size of the LN.
