Pilot Study to Measure Lung Biopsy Diagnostic Yield Using Always On Electromagnetic Tip Tracked Devices (ALOSPNDY)
|Pulmonary Coin Lesion||Procedure: Lung biopsy using Always On EM Tip Tracked Device||Phase 4|
|Study Design:||Allocation: Non-Randomized
Intervention Model: Single Group Assignment
Masking: Single Blind (Outcomes Assessor)
Primary Purpose: Diagnostic
|Official Title:||A Pilot Prospective Study Evaluating the SPiN Drive(TM)Electromagnetic Tip Tracked Devices Used in Diagnostic Bronchoscopy|
- Diagnostic yield of a subsegmental pulmonary lesion of less than 3.0 cm. [ Time Frame: Within 1 week ]Biopsy samples will be sent to the lab for analysis of the presence, absence, or identification of an occult particulate taken from the patient's lung. Patients with a negative biopsy result will be followed if recommended for another intervention and if recommended to watchful waiting. Follow up outcomes will be included in the outcome measures.
|Study Start Date:||June 2011|
|Estimated Study Completion Date:||November 2011|
|Estimated Primary Completion Date:||November 2011 (Final data collection date for primary outcome measure)|
Experimental: Patients recommended for a lung biopsy.
Patients with a positive diagnosis of a peripheral, less than 3.0 centimeter lung lesion, recommended for bronchoscopic biopsy are eligible to be consented into the study.
Procedure: Lung biopsy using Always On EM Tip Tracked Device
Patients screened by CT to have a subsegmental, less than 3.0 centimeter lung lesion will be assigned to outpatient bronchoscopy. The patient will have a chest CT with the Always on Patient vPad. Access to the lesion will be achieved using Electromagnetic Tip Tracked devices. Once accessed the operator will use the Electromagnetic Tip Tracked devices or standard devices to obtain a biopsy sample to then be to pathology for diagnosis and reporting. Once completed the patient will be moved to recovery and discharged. If the biopsy is negative the patient will be advised by the pulmonologist about other interventions, watchful waiting, or no further treatment. If the biopsy is positive, the patient will be referred to their physician for further treatment.
Other Name: Always On Electromagnetic Tip Tracked Diagnostic Yield
Always On EM Tip Tracked Steerable catheters and biopsy devices used with the Veran Medical Technologies system are Food and Durg Administration 510K approved for use in diagnostic pulmonary procedures to locate and sample subsegmental peripheral, less than 3.0 centimeter lung lesions or solitary pulmonary nodules(SPN).
Up to 20 subjects with radiographically confirmed peripheral lung lesions will be asked to participate in the study and proceed with informed consent. An interim analysis of the data will be conducted to determine the need to include an additional 10 patients to achieve statistically significant results at the ninety five percent confidence interval.
