Convex probe endobronchial ultrasound (CP EBUS), a non-surgical method to diagnose and treat a range of diseases affecting the lungs including cancer, has been introduced at Fortis Hiranandani Hospital in Navi Mumbai.
EBUS allows visualisation of airway tree with real-time ultrasound and permits visualisation of internal structure of pulmonary lesions.
The endobronchial ultrasound allows to see directly the changes that happen in early stages of diseases. It also permits sampling for histological confirmation.
EBUS has been widely used for sampling mediastinal lymph nodes, endobronchial ultrasound transbronchial needle aspiration (EBUS-TBNA) using both the radial probe as well as the convex probe and for peripheral lung lesions by transbronchial biopsies (EBUS-TBB) around the world.
Endobronchial application of ultrasound using a miniature probe introduced through a fibreoptic bronchoscope channel was first discovered in 1992.
The CP EBUS is a non-surgical day care procedure, and has a flexible bronchoscope with a linear curved array transducer on the tip with a frequency of five to 12 MHz that scans parallel to the insertion direction of the bronchoscope.
Images can be obtained by directly contacting the probe or by attaching a balloon on the tip and inflating with saline.
A dedicated needle is passed through the bronchoscopic ultrasound device and can be visualised through the optics and on the ultrasound image.
“A lot of activities are happening that is focusing on application of advanced bronchoscopic techniques for treatment of various malignant and non-malignant airway disorders,” stated Dr Rajeev Boudhankar, director, Fortis Hiranandani Hospital.
CP EBUS is most efficient due to immediate results and a favourable safety profile, according to him.
CP EBUS lymph node sampling compared with surgically resected specimens or clinical follow-up has a diagnostic accuracy of 93 to 97 percent.
CP EBUS comes a bit too costly for patients however. Patients will have to pay up to Rs 15000 for CP EBUS procedure, initially.
Over 100 CP EBUS have been sold worldwide till now and it is being deemed as a great breakthrough in the field of interventional pulmonology.
Indian bronchoscopy and pulmonology expert Dr Prashant Chhajed has been part of the team that has developed the CP-EBUS in collaboration with Olympus Optical Tokyo, Japan.
CP EBUS cost Rs 70 lakhs in India.
Fortis Hiranandani Hospital is the second hospital in India to have this device after the Kovai Medical Centre and Hospital in Coimbatore, Tamil Nadu. This technique is least invasive compared to the present methods available.
