Patients presenting with solitary or multiple lung nodules often require tissue confirmation in order to guide further management and determine if the lesion is benign or malignant. Several bronchoscopic techniques have emerged which have significantly improved the diagnostic yield of bronchoscopy in this setting, and in particular the combination of peripheral Endobronchial Ultrasonography (pEBUS) and Electromagnetic Navigation Bronchoscopy (ENB) has resulted in diagnostic yields of nearly 90%. In an attempt to reduce the significant cost of this combined approach, the sequential use of pEBUS followed by the more costly ENB technique only if a lesion is not identified on the ultrasound image could be as accurate. This study aims to determine the diagnostic yield of this sequential approach in patients with lung nodule(s).

Primary Outcome Measures:
  • diagnostic yield

Secondary Outcome Measures:
  • sensitivity, specificity, positive and negative predictive value
  • Impact of nodule size (<2 cm, 2-3 cm, >3cm) and distribution on diagnostic yield
  • Independent and incremental yield of BAL, biopsy, needle aspiration and brush cytology will be compared
  • Complication rate

Enrollment: 60
Study Start Date: June 2009
Study Completion Date: September 2010
Primary Completion Date: September 2010 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Sequential pEBUS - ENB Procedure: Sequential pEBUS - ENB

Subject will undergo bronchoscopy with peripheral endobronchial ultrasonography to identify the peripheral lung nodule. If the lesion is identified with pEBUS, samples will be collected.

If the lesion is not found by pEBUS, the electromagnetic navigation system will be deployed and directed to the lesion of interest, once again using pEBUS to confirm final location before samples are collected.
