Annual Report 2019

Department of Endoscopy, Respiratory Endoscopy Division

Takaaki Tsuchida, Yuji Matsumoto, Midori Tanaka

Introduction

 More than 1,300 bronchoscopies were performed between March 2019 and April 2020 (Table 1). We are one of the facilities with the highest number of bronchoscopies in Japan. Almost all cases of peripheral and central pulmonary lesions are diagnosed on an outpatient basis, and sedation is used in combination with bronchoscopy to reduce patient suffering.

 The special feature of our hospital is the use of endobronchial ultrasound (EBUS-TBNA, radial EBUS) for almost all examinations, and for small peripheral lesions, virtual bronchoscopy and virtual fluoroscopy using workstations and other instruments are used to simulate the lesion before the examination. Efforts were made to shorten the length of the procedure.

 Guided biopsies were combined with rapid onsite cytology. Cryobiopsies were used to diagnose ground grass nodules or to obtain large specimens especially for next generation sequencing.

The Team and What We Do

 Endobronchial ultrasonography (EBUS) is used not only to evaluate mediastinal or hilar malignant lesions but also to evaluate whether the biopsy devices can be directed to the peripheral lung lesions. Three hundred seventy-six cases of EBUS-TBNA (EBUS-guided transbronchial needle aspiration) were performed as a less invasive procedure to improve diagnosis for patients with mediastinal or hilar lymph node swelling. Transbronchial biopsies with virtual navigation were performed in most of the peripheral pulmonary lesions.

 Endobronchial stenosis patients were treated with airway stent placement, debulking with a cryoprobe and/or endobronchial electrocautery ablation. Medical thorachoscopy under local anesthesia in the endoscopic examination room were performed with unknown pleural effusion and/or pleural thickening.

Research activities

 We reported the results of a multicenter study of photodynamic therapy for peripheral small lung cancer with no serious adverse events.

 We demonstrated the usefulness of cryobiopsy in medical thoracoscopy under local anesthesia for the diagnosis of malignant pleural mesothelioma.

Clinical trials

 Preparations were made to initiate the world's first multicenter trial of photodynamic therapy for peripheral type lung cancer.

Education

 A flexible bronchoscope was developed for the first time in the world in this institution. There are many resident and overseas doctors wishing to train at our division. We were given the opportunity of writing papers and conference presentations for many residents. Overseas training doctors came from many countries.

Future prospects

1) We will initiate a multicenter clinical trial of photodynamic therapy for small peripheral lung cancer.

2) We will develop a new method of diagnosing malignant tumors using a desktop electron microscope.

3) We will develop methods of diagnosis and treatment using the minimally invasive technique of bronchoscopy.

4) We will study the multidimensional analysis of lung cancer pathology using pathology information, ultra-high-definition CT images, and medical information to investigate the diagnostic potential of ultra-high-definition CT images for lung cancer.

5) We plan to conduct a prospective observational study using a multicenter collaborative database on respiratory endoscopy.

6) We will conduct an observational study on the usefulness of the new cryoprobe in transbronchial lung biopsy for peripheral lung lesions.
