Interventional endoscopy (e.g., bronchoscopy, colonoscopy, laparoscopy, cystoscopy) is a widely performed procedure that involves either diagnosis of suspicious lesions or guidance for minimally invasive surgery in a variety of organs within the body cavity. Endoscopy may also be used to guide the introduction of certain items (e.g., stents) into the body. Endoscopic navigation systems seek to integrate big data with multimodal information (e.g., computed tomography, magnetic resonance images, endoscopic video sequences, ultrasound images, external trackers) relative to the patient's anatomy, control the movement of medical endoscopes and surgical tools, and guide the surgeon's actions during endoscopic interventions...

PURPOSE: Bronchoscopy for peripheral pulmonary lesions continues to present challenges to clinicians. One potential limitation may be the inability to advance conventional bronchoscopes into close proximity of peripheral lesions prior to biopsy. This study was performed to assess the reach of a robotic endoscopic system within human cadaveric lungs compared to conventional thin bronchoscopes. DESCRIPTION: All segmental bronchi (RB1-10, LB1-10) were accessed in two human cadavers using a conventional thin bronchoscope and robotic endoscope of identical outer diameter...

We describe a novel method using electromagnetic navigation bronchoscopy (ENB) without dye marking to perform vectorial localization for an impalpable peripheral lesion in the right lower lobe during diagnostic surgical resection in a 52-year-old woman. After the ENB registration process, the anesthetist changed the single-lumen endotracheal tube to a double-lumen endobronchial tube. Guided by the ENB system, the operator delivered the probe of the locatable guide to the planned site through the right lumen of the endobronchial tube...

Lung nodules are being increasingly detected, particularly with lung cancer screening with low-dose computed tomography. Although the vast majority of lung nodules are benign, many often require tissue diagnosis. Several modalities to obtain diagnostic tissue from peripheral lung nodules are available. Bronchoscopic modalities such as radial ultrasound and electromagnetic navigational bronchoscopy are becoming increasingly used because of their superior safety profile and improving diagnostic yield. Although these modalities continue to become more advanced, newer and complementary technologies appear promising...

OBJECTIVE: In the setting of lung cancer, photodynamic therapy (PDT) is typically used to treat centrally located endobronchial tumors. The development of navigational bronchoscopy has opened the potential for using PDT to treat peripheral lung tumors. However, there is limited information about the feasibility of this approach for treating peripheral lung cancers, and about its effects on surrounding healthy lung tissue. We studied the use of PDT delivered by electromagnetic navigational bronchoscopy to treat peripheral lung cancer in dogs...

Robotic resection of pulmonary lesions has become a more common approach in the field of thoracic surgery. The greatest drawback of robotic resection is the lack of tactile feedback as compared to open approaches, making identification of intrapulmonary lesion difficult. Electromagnetic navigational bronchoscopy (navibronch) enables pre-incisional marking of pulmonary lesions for intraoperative identification. We sought to determine how effective navibronch was in our institution's robotic cases. Thirty-one patients underwent robotically assisted resection of 35 lesions with the assistance of navibronch from 7/2014 to 9/2015...

BACKGROUND: Assessment of competency in bronchoscopy has traditionally been undertaken in clinical settings, however, recent recognition of increased procedural complications and learner anxiety have led to interest in simulation-based competency assessment. The aim of this study was to determine if low-fidelity simulation-based assessment allows discrimination of competency based on prior experience between bronchoscopists. METHODS: Forty-four participants were allocated to 3 groups based on prior bronchoscopic experience [novices (n=31) with no prior experience, intermediates (n=7) with prior experience of 5 to 10 bronchoscopies, and expert bronchoscopists (n=6) with minimum 200 prior bronchoscopies performed]...

BACKGROUND: Advances in bronchoscopy and CT-guided lung biopsy have improved the evaluation of small pulmonary lesions (PLs), leading to an increase in preoperative histological diagnosis. We aimed to evaluate the efficacy and safety of transbronchial lung biopsy using radial endobronchial ultrasound and virtual bronchoscopic navigation (TBLB-rEBUS&VBN) and CT-guided transthoracic needle biopsy (CT-TNB) for tissue diagnosis of small PLs. METHODS: A systematic search was performed in five electronic databases, including MEDLINE, EMBASE, Cochrane Library Central Register of Controlled Trials, Web of Science, and Scopus, for relevant studies in May 2016; the selected articles were assessed using meta-analysis...

Background: Various techniques have been introduced to decrease complications during nasotracheal intubation. A common practice is to use nasal packing with a cotton stick and 0.01% epinephrine jelly. However, this procedure can be painful to patients and can damage the nasal mucosa. Xylometazoline spray can induce effective vasoconstriction of the nasal mucosa without direct nasal trauma. In this study, we aimed to compare the efficacy of these two methods. Methods: Patients were randomly allocated into two groups (n = 40 each): xylometazoline spray group or epinephrine packing group...

Bronchoscopic examination has a key role in diagnosing or further specifying of a broad spectrum of respiratory diseases. Although classic bronchoscopy with its rigid instrumentation still upholds its position, the vast majority of procedures are performed with flexible bronchoscopes. Diagnostic possibilities are broadened by new technical findings and procedures, such as endobronchial ultrasonography, examination through autofluorescence, navigated bronchoscopy and others. The material for cytological, microbiological or other examinations can be sampled through a whole number of procedures using specialized instruments...

Background: Electromagnetic navigation bronchoscopy (ENB) is emerging as a useful new technique for diagnosing small pulmonary peripheral lesions (SPPLs). However, the accuracy and efficiency of ENB have not been investigated in Asian populations where the differential diagnoses for SPPLs may be different. To analyze this question, this study included patients who received diagnostic ENB followed by surgery for the excision of SPPLs. Methods: Consecutive patients referred to the Department of Thoracic Surgery, Shanghai Pulmonary Hospital (Tongji University), between May 2014 and April 2015 were recruited...
