Abstract
OBJECTIVES To investigate the clinical value of rigid bronchoscopy combined with fiberoptic bronchoscopy in patients with early bronchogenic lung cancer who underwent sleeve lobectomy. METHODS A retrospective study was performed on 76 patients with early bronchogenic lung cancer admitted to our center from March 2016 to March 2017. Patients in the control group received conventional sleeve lobectomy (n = 38), while patients in the observation group underwent sleeve lobectomy by using rigid bronchoscopy combining fiberoptic bronchoscopy (n = 38). We compared perioperative period indicators and the recovery of pulmonary function indexes one month after the operation were compared in two groups. The prognosis of the patients were also analyzed. RESULTS Compared with the control group, the intraoperative blood loss, operation duration and airway reconstruction duration in the observation group were significantly reduced. The total incidence of perioperative complications was markedly lower in the observation group than in the control group. The percentage of DLCO% was significantly improved in the observation group. The relapse-free survival (RFS) in the observation group was remarkably longer than in the control group. CONCLUSION Rigid bronchoscopy combined with fiberoptic bronchoscopy is beneficial to improve the clinical outcome and prognosis of patients with early bronchogenic lung cancer more effectively.

Abstract
The structure of a traditional rigid bronchoscope includes proximal, distal, and body, representing an important means to treat hypoxic diseases. However, the body structure is too simple, resulting in the utilization rate of oxygen being usually low. In this work, we reported a deformable rigid bronchoscope (named Oribron) by adding a Waterbomb origami structure to the body. The Waterbomb's backbone is made of films, and the pneumatic actuators are placed inside it to achieve rapid deformation at low pressure. Experiments showed that Waterbomb has a unique deformation mechanism, which can transform from a small-diameter configuration (#1) to a large-diameter configuration (#2), showing excellent radial support capability. When Oribron entered or left the trachea, the Waterbomb remained in #1. When Oribron is working, the Waterbomb transforms from #1 to #2. Since #2 reduces the gap between the bronchoscope and the tracheal wall, it effectively slows down the rate of oxygen loss, thus promoting the absorption of oxygen by the patient. Therefore, we believe that this work will provide a new strategy for the integrated development of origami and medical devices.

Abstract
Lung cancer is the second-most commonly diagnosed cancer and the leading cause of cancer death worldwide. The most common histological type is non-small-cell lung cancer, accounting for 85% of all lung cancer cases. About one out of three new cases of non-small-cell lung cancer are diagnosed at a locally advanced stage—mainly stage III—consisting of a widely heterogeneous group of patients presenting significant differences in terms of tumor volume, local diffusion, and lymph nodal involvement. Stage III NSCLC therapy is based on the pivotal role of multimodal treatment, including surgery, radiotherapy, and a wide-ranging option of systemic treatments. Radical surgery is indicated in the case of hilar lymphnodal involvement or single station mediastinal ipsilateral involvement, possibly after neoadjuvant chemotherapy; the best appropriate treatment for multistation mediastinal lymph node involvement still represents a matter of debate. Although the main scope of treatments in this setting is potentially curative, the overall survival rates are still poor, ranging from 36% to 26% and 13% in stages IIIA, IIIB, and IIIC, respectively. The aim of this article is to provide an up-to-date, comprehensive overview of the state-of-the-art treatments for stage III non-small-cell lung cancer.

Abstract
Simple Summary Postoperative residual pleural space and postoperative air leaks after lung resection are two different clinical entities requiring completely different approaches. Residual postoperative pleural space is a part of the pleural cavity that is not fully reoccupied by the remaining lung after pulmonary resection. No treatment is needed in the asymptomatic residual pleural space without any persistent air leak, and chest drain removal can be safely planned. On the contrary, an active and prolonged air leak after lung resection is an absolute contraindication to chest drain removal that may culminate in hypertensive pneumothorax, subcutaneous emphysema, and severe respiratory symptoms. In order to further contribute to an appropriate differential diagnosis between these two settings, we propose a radiological sign that is observed only in the case of residual plural space. In this case, in fact, the lung takes the form of a round balloon due to the hyperinflation condition, which is governed by the Young–Laplace equation describing the capillary pressure difference sustained across the interface between two static fluids, such as water and air, due to the phenomenon of wall tension. Abstract In this paper, we propose a radiological sign for an appropriate differential diagnosis between postoperative pleural space and active air leak after lung resection. In the case of residual pleural space without any active air leak, the lung takes the form of a round balloon due to the hyperinflation condition, which is governed by the Young–Laplace equation describing the capillary pressure difference sustained across the interface between two static fluids, such as water and air, due to the phenomenon of wall tension. The two principal mechanisms by which a lung forms a spherical image are shear-controlled detachment induced by shear stress on the membrane surface, and spontaneous detachment induced by a gradient in Young–Laplace pressure. On the contrary, the lung maintains its tapered shape in the case of an active air leak because the continuous air refill does not allow a complete parenchyma re-expansion.

Abstract
BACKGROUND At present, bronchoscopic intervention has become an important treatment approach for central airway obstruction (CAO). Choosing an appropriate access channel for different patients during this operation has become a research focus. METHODS Data of bronchoscopic interventions in 201 patients with CAO in which one of endotracheal intubation, laryngeal mask, or rigid bronchoscope were used as the only access channel were retrospectively reviewed. RESULTS The total immediate effective rate was 94.1% (398/423), and the main complications related to the access channels included hypoxemia, elevated arterial partial pressure of carbon dioxide, arrhythmia, airway mucosa tear, glottic edema, vocal cord injury, tooth loss, massive bleeding, airway mucosal necrosis, and asphyxia. The incidence of complications was 16.8% (71/423). Glottic edema was the most common complication with an incidence of 7.8% (33/423) and accounted for 46.5% of all complications. Glottic edema only occurred in the laryngeal mask and rigid bronchoscope groups, and the incidence was significantly correlated with the operation time (p < 0.001). Massive bleeding related to the access channel remains the most serious complication. CONCLUSIONS Endotracheal intubation, laryngeal mask, and rigid bronchoscope each have their own advantages and disadvantages. The most appropriate access channel should depend on a comprehensive assessment of the patient.

Abstract
INTRODUCTION Interventional bronchoscopy is now the standard treatment for tracheobronchial narrowing due to tumor. The objective of our study was to analyze long-term survival and complications occurring in patients with malignant airway obstruction. METHODS We retrospectively studied the data from 93 patients treated between 2008 and 2019. RESULTS One hundred and eleven therapeutic bronchoscopies were performed. Sixty-seven patients had primary lung cancer, in 17 had tumors of another origin and 9 patients had benign or local lung tumors. Thulium laser was frequently used prior to tumor enucleation and to restore hemostasis. Seventy-one silicone stents were inserted. The death rate at the time of the procedure was 1.8% and immediate complication occurred in 9.9% of the patients. Long-term survival was significantly better for patients with cancer from other origins than in those with primary lung cancer (615.5days versus 177.9days). On the other hand, there was no significant difference in long-term survival between patients with locally advanced and metastatic lung cancer with endobronchial lesions treated by stent and those who were not (234.2days versus 164.6days). All patients with benign or with locally malignant tumors were still alive. CONCLUSION Therapeutic bronchoscopy increases the long-term survival of patients with malignant airway obstruction. The risk-benefit ratio was favorable.

Abstract
Flexible video bronchoscopy is a procedure that plays an important role in diagnosing various types of pulmonary lesions and abnormalities. Case 1 is a 68-year-old male patient with a lesion in the right lung apex of approximately 4 mm × 28 mm with atelectasis bands due to a crash injury. High-flow system with 35 L/min and fraction of inspired oxygen (FiO2) 0.45 and temperature of 34 °C was installed prior to the video bronchoscopy. SpO2 was maintained at 98%-100%. The total dose of sedative was 50 mg of propofol. In Case 2, a 64-year-old male patient with bronchiectasis, cystic lesions and pulmonary fibrosis of the left lung field was placed on a high-flow system with 45 L/min and 0.35 FiO2 at a temperature of 34 °C. SpO2 was maintained at 100%. The total duration of the procedure was 25 min; SpO2 of 100% was sustained with oxygenation during maintenance time with the flexible bronchoscope within the airway. The total dose of propofol to reach the degree of desired sedation was 0.5-1 mg/kg. Both patients presented hypotension. For the patient of case 1, a vasopressor (norepinephrine at doses of 0.04 µg/kg/min) was given, and for the patient of case 2, only saline volume expansion was used. The video bronchoscopy with propofol sedation and high-flow nasal cannula allows adequate oxygenation during procedure in the intensive care unit.

Abstract
The purpose of this study is to report our experiences over 12 years with bronchoscopic interventions in patients with benign central airway stenosis using three types of working channels (rigid bronchoscope, laryngeal mask, and endotracheal intubation), with a focus on their related advantages, disadvantages, and postoperative complications. We analyzed the clinical data from 273 patients with benign central airway stenosis who underwent a bronchoscopic intervention. The Wilcoxon rank-sum test was used to analyze the immediate results after the first bronchoscopic intervention, and the Chi-square test was used to analyze the correlation between glottic edema and operation time. The 273 patients underwent a total of 479 bronchoscopic interventions, with satisfactory results. The immediate effective rates of the first bronchoscopic intervention by rigid bronchoscope, laryngeal mask, and endotracheal intubation were 91.4%, 91.3%, and 85.2%, respectively. Postoperative complications related to the working channels included hoarseness, glottic edema, pharyngalgia, paresthesia pharynges, cough, and tooth loss. Glottic edema was the most serious complication, and it occurred in 37.7% (23/61) of the rigid bronchoscope group and 9.8% (32/326) in the laryngeal mask group. And the incidence rate was significantly correlated with the operation time (P < 0.01). Therefore, for patients with benign central airway stenosis, the best choice of working channel during an operation should be made by the operation procedure, lesion location, and pathology of the patients. Shortening the operation time was an important factor in preventing glottic edema.

Abstract
Background Airway stenting is frequently used in the palliative treatment of patients with advanced tumor-induced airway stenosis and fistulas. However, there is paucity of studies regarding the use of airway stents in restoring patency. The aim of the study was to assess the efficacy and safety of hybrid silicon Y stents and covered self-expanding metal stents (SEMS) and in reestablishing patency in airway stenoses and fistulas. Methods This retrospective study included 31 patients between January 2016 to December 2019 with inoperable complex malignant airway stenoses and fistulas, managed with Silicone Y stents, and covered SEMS. The clinical details, clinical outcomes and complications up to 6 months were extracted from medical records. The improvement of performance was assessed based on modified British Medical Research Council (mMRC) dyspnea scores (t=6.892, P<0.001), Karnofsky Performance Scores (KPS) (t=-11.653, P<0.001), and performance status (PS) (t=3.503, P<0.001). Result A total of 31 silicon Y stents and 35 covered SEMSs were inserted. Of the 31 patients (M:F 20:11; age: 54.64±9.57), 25/31 (80.6%) experienced immediate relief of symptoms following stent placement. Patients' mMRC dyspnea scores, KPS, and PS showed significant improvement following stenting. The mean duration of stent placement was 146.3±47.7 days, and 17/31 (55%) patients were alive at 6 months. No major complications related to hybrid stenting were observed during the follow-up period. Conclusions Hybrid stenting is a feasible and safe palliative treatment for malignant airway stenosis and fistulas to improve quality of life and can be performed without major complications.

Safety application of muscle relaxants and the traditional low-frequency ventilation during the flexible or rigid bronchoscopy in patients with central airway obstruction: a retrospective observational study. BMC Anesthesiol 2021; 21:106. [PMID: 33823804 PMCID: PMC8022393 DOI: 10.1186/s12871-021-01321-w] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/15/2020] [Accepted: 03/25/2021] [Indexed: 11/23/2022] Open
Abstract
Background Bronchoscopy treatments of central airway obstruction (CAO) under general anesthesia are high-risky procedures, and posing a giant challenge to the anesthesiologists. We summarized and analyzed our clinical experience in patients with CAO undergoing flexible or rigid bronchoscopy, to estimate the safety of skeletal muscle relaxants application and the traditional Low-frequency ventilation. Methods Clinical data of 375 patients with CAO who underwent urgent endoscopic treatments in general anesthesia from January 2016 to October 2019 were retrospectively reviewed. The use ratio of skeletal muscle relaxants, dose of skeletal muscle relaxants used, the incidence of perioperative adverse events, adequacy of ventilation and gas exchange, post-operative recovery between rigid bronchoscopy and flexible bronchoscopy therapy, and risk factors for postoperative ICU admission were evaluated. Results Of the 375 patients with CAO, 204 patients were treated with flexible bronchoscopy and 171 patients were treated with rigid bronchoscopy. Muscle relaxants were used in 362 of 375 patients (including 313 cisatracurium, 45 rocuronium, 4 atracurium, and 13 unrecorded). The usage rate of muscle relaxants (96.5% in total) was very high in patients with CAO who underwent either flexible bronchoscopy (96.6%) or rigid bronchoscopy (96.5%) therapy. The dosage of skeletal muscle relaxants (Cisatracium) used was higher in rigid bronchoscopy compared with flexible bronchoscopy therapy (10.8 ± 3.8 VS 11.6 ± 3.6 mg, respectively, p < 0.05). No patient suffered the failure of ventilation, bronchospasm and intraoperative cough either in flexible or rigid bronchoscopy therapy. Hypoxemia was occurred in 13 patients (8 in flexible, 5 in rigid bronchoscopy) during the procedure, and reintubation after extubation happened in 2 patients with flexible bronchoscopy. Sufficient ventilation was successfully established using the traditional Low-frequency ventilation with no significant carbon dioxide accumulation and hypoxemia occurred both in flexible and rigid bronchoscopy group (p > 0.05). Three patients (1 in flexible and 2 in rigid) died, during the post-operative recovery, and the higher grade of American Society of Anesthesiologists (ASA) and obvious dyspnea or orthopnea were the independent risk factors for postoperative ICU admission. Conclusion The muscle relaxants and low-frequency traditional ventilation can be safely used both in flexible and rigid bronchoscopy treatments in patients with CAO. These results may provide strong clinical evidence for optimizing the anesthesia management of bronchoscopy for these patients.

Abstract
Supporting patients suffering from severe respiratory diseases with mechanical ventilation, obstacles are often encountered due to pulmonary and/or thoracic alterations, reductions in the ventilable lung parenchyma, increases in airway resistance, alterations in thoraco-pulmonary compliance, advanced age of the subjects. All this involves difficulties in finding the right ventilation parameters and an adequate driving pressure to guarantee sufficient ventilation. Therefrom, new mechanical ventilation techniques were sought that could help overcome the aforementioned obstacles. A new mode of mechanical ventilation is being presented, i.e., a Positive + Negative Synchronized Ventilation (PNSV), characterized by the association and integration of two pulmonary ventilators; one acting inside the chest with positive pressures and one externally with negative pressure. The peculiarity of this combination is the complete synchronization, which takes place with specific electronic modifications. The PNSV can be applied both in a completely non-invasive and invasive way and, therefore, be used both in acute care wards and in ICU. The most relevant effect found, due to the compensation of opposing pressures acting on the chest, is that, during the entire inspiratory act created by the ventilators, the pressure at the alveolar level is equal to zero even if adding together the two ventilators' pressures; thus, the transpulmonary pressure is doubled. The application of this pressure for 1 hour on elderly patients suffering from severe acute respiratory failure, resulted in a significant improvement in blood gas analytical and clinical parameters without any side effects. An increased pulmonary recruitment, including posterior lung areas, and a reduction in spontaneous ventilatory rate have also been demonstrated with PNSV. This also paves the way to the search for the best ventilatory treatment in critically ill or ARDS patients. The compensation of intrathoracic pressures should also lead, although not yet proven, to an improvement in venous return, systolic and cardiac output. In the analysis of the study in which this method was applied, the total transpulmonary pressure delivered was the sum of the individual pressures applied by the two ventilators. However, this does not exclude the possibility of reducing the pressures of the two machines to modulate a lower but balanced total transpulmonary pressure within the chest.

Abstract
Tracheobronchial tumors with involvement of the carina represent a challenging problem in the pulmonary surgery. Carinal resection is referred to removal and reconstruction of the airway itself, whereas concomitant removal of the lung parenchyma (usually a whole lung) is termed as carinal pneumonectomy. Thorough preoperative workup of these patients is mandatory. Meticulous surgical technique and aggressive postoperative management is required for the best outcomes in these difficult cases. In the paper authors review surgical technique, evaluation and management of this challenging patient population.

Abstract
Respiratory failure is one of the most important risk factors for diagnostic bronchofiberoscopy (BF), whereas therapeutic bronchoscopies are typically performed in intubated patients. Only a few published studies analyzed the outcomes of noninvasive mechanical ventilation (NIV)-facilitated BF. In this case series, we present our experiences with NIV-facilitated diagnostic and therapeutic BF performed in patients with respiratory failure that was associated with acute interstitial pulmonary disease, chronic obstructive pulmonary disease, cystic fibrosis exacerbation, foreign body aspiration, tracheal stenosis, pneumonia, and in a patient with a neuromuscular disease. All of the patients were initially hypoxic and some had PaO2/FiO2 < 200, which corresponded to moderate-to-acute respiratory distress syndrome (ARDS). NIV-facilitated BF were performed for the diagnostic or therapeutic purposes. The former consisted of bronchoalveolar lavage and bacterial sampling in a patient with impaired cough reflex, airway assessment in otherwise unexplained respiratory failure and hemoptysis, and the latter of mucous plugs resolution, foreign body removal, and assistance in weaning from mechanical ventilation. All procedures were carried out using NIV in the spontaneous timed (ST) or average volume assured pressure support (AVAPS) mode with oxygen supplementation. There were no procedure-related complications noticed during NIV-facilitated BF. We conclude that NIV is a useful and safe tool that facilitates the performance of BF in severe pulmonary diseases. Prospective studies are required to set the recommendations for the procedure and to define the optimum ventilatory modes to be used.

Abstract
OBJECTIVE This paper describes a surgical device that provides both wrist and elbow dexterity without motors or electronics. The device provides dexterity advantages in minimally invasive surgery typically associated with robotic systems, but does so with many fewer components. Fully mechanical designs of this type promise to deliver "robot-like dexterity" at a lower financial cost than current surgical robotic systems. METHODS Most non-robotic articulated surgical tools developed to date feature one or two degrees-of-freedom (DOF) close to the tool tip (i.e., a "wrist"). In this paper, we describe a new tool that not only features a two-DOF wrist, but also augments its dexterity with a two-DOF "elbow" consisting of a multi-backbone design seen previously only in robotic systems. Such an elbow offers high stiffness in a thin form factor. This elbow requires static balancing, which we accomplish with springs in the handle, so that the surgeon can benefit from the stiffness without feeling it while using the device. RESULTS We report the overall tool design and experiments evaluating how well our static balance mechanism compensates for the multi-backbone elbow's intrinsic stiffness. CONCLUSION We demonstrate the use of a multi-backbone elbow in a manual tool for the first time and show how to combine the elbow with a pin joint wrist in a fully mechanical (i.e., non-robotic) tool. SIGNIFICANCE This paper is a step toward high dexterity, low-cost surgical instruments that bring some benefits of surgical robotic systems to patients and surgeons at a lower cost.

Abstract
We describe the novel combined use of a fiberoptic bronchoscope and a Fuji Uniblocker placed outside the endotracheal tube (ETT) for removal of a retained BioGlue polymerized tissue fragment (2.8 × 0.8 cm) from the right main bronchus (RMB). The patient was a trauma victim who presented with a diffuse axonal injury, cervical spine and maxillofacial injuries, and a flail chest, and the procedure we describe took place following the surgical repair of a disrupted left main bronchus. Endoscopic retrieval using different sizes of grasping forceps and a Dormia basket failed to remove the foreign body (FB). Under combined GlideScope videolaryngoscopic and bronchoscopic guidance, a 9.0 F Uniblocker was introduced outside the ETT, placed into the RMB beyond the FB, initially inflated, and then gradually increased in volume during withdrawal from the RMB into the trachea so as to trap the FB between the tip of the ETT and the blocker balloon. The ETT, bronchoscope, blocker catheter, and the FB were then removed from the glottis as a single unit. The FB was then removed using Magill forceps with the aid of a GlideScope. We conclude that the combined use of a GlideScope, bronchoscope, and an Uniblocker placed outside the ETT can be an effective method for removal of a retained FB.

Abstract
OBJECTIVES In the literature, inconsistent associations between the primary locations of lung adenocarcinomas (ADCs) with patient prognosis have been reported, due to varying definitions for central and peripheral locations. In this study, we investigated the clinical characteristics and prognoses of ADCs located in the main bronchus. METHODS A total of 397,189 lung ADCs registered from 2004 to 2013 in the National Cancer Database (NCDB) were extracted and divided into main bronchus-located ADCs (2.5%, N = 10,111) and non-main bronchus ADCs (97.5%, N = 387,078). The ADCs located in the main bronchus and those not in the main bronchus were compared in terms of patient prognosis, lymph node involvement, distant metastases and other clinical features, including rate of curative-intent resection, histologic grade, and stage. RESULTS ADCs located in the main bronchus had significantly worse patient survival than those in the non-main bronchus, both for all patients (HR = 1.82, 95% CI 1.78-1.86) and for those undergoing curative-intent resection (HR = 2.49, 95% CI 2.23-2.78). Furthermore, ADCs located in the main bronchus had a significantly higher rate of lymph node involvement and distant metastasis than those not in the main bronchus, when stratified by tumor size (trend test, p < e-16). Multivariate analysis of overall survival showed that main bronchus location is a prognostic factor (HR = 1.15, 95% CI 1.08-1.23) independent of other clinical factors. CONCLUSIONS Main bronchus location is an independent predictor for metastasis and worse outcomes irrespective of stage and treatment. Tumor primary location might be considered in prognostication and treatment planning.

Abstract
Endoscopy of the airway is a valuable tool for the evaluation and management of airway disease. It can be used to evaluate many different bronchopulmonary diseases including airway foreign bodies, tumors, infectious and inflammatory conditions, airway stenosis, and bronchopulmonary hemorrhage. Traditionally, options for evaluation were limited to flexible and rigid bronchoscopy. Recently, more sophisticated technology has led to the development of endobronchial ultrasound (EBUS) and electromagnetic navigational bronchoscopy (ENB). These technological advances, combined with increasing provider experience have resulted in a higher diagnostic yield with endoscopic biopsies. This review will focus on the role of bronchoscopy, including EBUS, ENB, and rigid bronchoscopy in the diagnosis of bronchopulmonary diseases. In addition, it will cover the anesthetic considerations, equipment, diagnostic yield, and potential complications.

Abstract
Background: A limitation of bronchoscopic balloon dilatation (BBD) is that airflow must be completely blocked for as long as possible during the operation. However, the patient often cannot hold his or her breath for a long period affecting the efficacy of the procedure. In this study, we used an extra-small-diameter tube to provide assisted ventilation to patients undergoing BBD and assessed the efficacy and safety of this technique. Methods: Bronchoscopic balloon dilatation was performed in 26 patients with benign tracheal stenosis using an extra-small-diameter tube. The tracheal diameter, dyspnea index, blood gas analysis results, and complications were evaluated before and after BBD. Statistical analyses were performed by SPSS version 16.0 for Windows (SPSS, Inc., Chicago, IL, USA). Results: Sixty-three BBD procedures were performed in 26 patients. Dyspnea immediately improved in all patients after BBD. The tracheal diameter significantly increased from 5.5 ± 1.5 mm to 13.0 ± 1.3 mm (P < 0.001), and the dyspnea index significantly decreased from 3.4 ± 0.8 to 0.5 ± 0.6 (P < 0.001). There was no significant change in the partial pressure of oxygen during the operation (before, 102.5 ± 27.5 mmHg; during, 96.9 ± 30.4 mmHg; and after, 97.2 ± 21.5 mmHg; P = 0.364), but there was slight temporary retention of carbon dioxide during the operation (before, 43.5 ± 4.2 mmHg; during, 49.4 ± 6.8 mmHg; and after, 40.1 ± 3.9 mmHg; P < 0.001). Conclusion: Small-diameter tube-assisted BBD is an effective and safe method for the management of benign tracheal stenosis.

Abstract
Flexible and rigid bronchoscopes are used in diagnosis, therapeutics, and palliation. While their use is widespread, effective, and generally safe; there are numerous potential complications that can occur. Mechanical complications of bronchoscopy are primarily related to airway manipulations or bleeding. Systemic complications arise from the procedure itself, medication administration (primarily sedation), or patient comorbidities. Attributable mortality rates remain low at < 0.1% for fiberoptic and rigid bronchoscopy. Here we review the complications (classified as mechanical or systemic) of both rigid and flexible bronchoscopy in hope of making practitioners who are operators of these tools, and those who consult others for interventions, aware of potential problems, and pitfalls in order to enhance patient safety and comfort.
