The Analysis of the EBUS Scope as a Hybrid Bronchoscope

1. Objectives (include all primary and secondary objectives)

Primary objective - To study and more fully describe the full spectrum of procedures performed using an EBUS bronchoscope outside of EBUS-TBNA. 2. Background (briefly describe pre-clinical and clinical data, current experience with procedures, drug or device, and any other relevant information to justify the research)

There currently exists only anecdotal evidence and individual reports of the use of EBUS bronchoscopes in the performance of non-EBUS-TBNA procedures. Given the full size working channel through which all standard bronchoscopic tools are able to pass, the EBUS bronchoscope has been reported to have been used in the performance of other procedures such as BAL, TBBx, EBBx and airway brushing. Frequently during bronchoscopic procedures in which EBUS-TBNA is used to sample lymph nodes within the hilum and mediastinum there exists a need to perform other procedures including but not limited to those listed above. In these cases, the EBUS bronchoscope is removed and exchanged for a standard video bronchoscope often times dirtying the scope for only a single procedure. We routinely use EBUS bronchoscopy in our daily practice as interventional pulmonologists and would like to study the use of these bronchoscopes in the performance of procedures other than TBNA perhaps in an effort to more fully understand the benefits and limitations associated with the use of an EBUS bronchoscope during conventional video bronchoscopy. 3. Study Procedures

1. Study design

We plan to collect the data for all clinically indicated procedures using an EBUS bronchoscope over a twelve month time frame in the JHH outpatient endoscopy suite. No procedures will be performed for research purposes. No additional procedures will be performed outside the scope of standard practice. 2. Study duration and number of study visits required of research participants. 12 month study duration, no research visits will be required. 3. Justification of why participants will not receive routine care or will have current therapy stopped.
