using the endoscope for endobronchial ultrasound in the esophagus

Endoscopic ultrasound is a key procedure in the diagnosis and staging of lung cancer and allows safe sampling from mediastinal or hilar lymph nodes1,2. Endoscopic ultrasound comprises endobronchial (EBUS) and transesophageal ultrasound (EUS), are considered complementary procedures2.
Interventional pulmonologists are trained with the EBUS endoscope but are rarely familiar with the larger EUS endoscope (Figure 1), which requires special training to handle correctly3. EBUS and EUS are often performed by different departments and on separate sessions/days4. However, trained pulmonologists experienced with EBUS techniques can insert the smaller EBUS endoscope into the esophagus and perform safe examination and biopsy sampling from mediastinal lymph nodes and other lesions adjacent to the esophagus and stomach - a technique termed as EUS-B5. This leads to extension of pulmonologists&#39; ability to safely and conclusively sample lesions in many different anatomical sites such as lung6, pleura7, pericardial effusion8, mediastinal lymph nodes1,5, left liver lobe and retroperitoneal lymph nodes9, pancreas10 and the left adrenal gland11,12 (Figure 2).
The EUS-B procedure is a pulmonologist friendly version of the gastroenterologists&#180; EUS using an endoscope that the pulmonologist already masters. The EUS procedure is performed with a gastroendoscope which is both larger and heavier than the EBUS endoscope, has a different handle (with wheels, see Figure 1) and is unlike EBUS performed with the patient in left lateral decubitus. Learning EUS as a pulmonologist is challenging and requires a lot of training and supervision2.
EUS-B and EUS are so far very similar regarding diagnostic yield when performed in the field of pulmonology5,13,14,15. EUS-B is patient friendly since the endoscope is significantly thinner than that of EUS, and therefore less unpleasant for the pharynx and esophagus. Unlike EBUS, EUS-B does not cause direct airway irritation and is therefore safe to use in patients with suspected cancer resulting in severe respiratory impairment due to mediastinal tumor masses16.
The combination of EBUS and EUS-B is preferred over either test alone in any patient suspected of lung cancer, but EUS-B should especially be considered in patients with suspicious lesions out of reach by EBUS, but within range by transesophageal ultrasound (Figure 2). Adding EUS-B to EBUS in lung cancer work-up expands the interventional pulmonologists&#180; ability to perform diagnostic work-up during a single session using the same endoscope by one proceduralist, which is more convenient for the patient, saving both time and costs.
The complication risk of EUS-B is extremely low and is to our knowledge only limited to infectious complications17,18. EUS-B training should be easy and a natural continuation of EBUS, and the following protocol will describe how to perform EUS-B in mild sedation in an out-patient clinical setting.

Our scope is to identify new ways to perform biopsies from otherwise difficult to access areas in the most patient-friendly way. Thus, conclusive biopsies with few adverse events, low patients discomfort, and low costs. EUS-B is a safe technique in the hands of respiratory physicians.Despite that biopsies are taken not from the lungs or airways, but from the esophagus or stomach, it allows for more complete investigation of patients with possible lung cancer or other cancer. We have contributed significantly to the field by exploring utility and safety of EUS-B, including identification of new targets that can be reached and sampled. The aspect of patient safety is of utmost importance, and EUS-B has no serious complications.EUS-B is an emerging technique, and there's still no simulators or phantoms that allows for safe learning of the technique. This protocol provides a clear and stepwise instruction to support beginners and mentors to improve the learning curve.
