PURPOSE OF REVIEW
This article provides an overview of standard procedures currently performed in nonoperating room anesthesia (NORA) and highlights anesthetic implications.
RECENT FINDINGS
Novel noninvasive interventional procedures remain on the rise, accelerating demand for anesthesia support outside the conventional operating room. The field of interventional oncology has introduced a variety of effective minimally invasive therapies making interventional radiology gain a major role in the management of cancer. Technical innovation brings newer ablative and embolotherapy techniques into practice. Flexible bronchoscopy has replaced rigid bronchoscopy for many diagnostic and therapeutic indications. Endobronchial ultrasonography now allows sampling of mediastinal, paratracheal, or subcarinal lymph nodes rendering more invasive procedures such as mediastinoscopy unnecessary. Similarly, endoscopic ultrasonosgraphy currently plays a central position in the management of gastrointestinal disease. Sophisticated catheter techniques for ablating cardiac arrhythmias have become state of the art; Watchman procedure gaining position in the prevention of stroke resulting from atrial fibrillation.
SUMMARY
NORA is a rapidly evolving field in anesthesia. Employing new technology to treat a wide variety of diseases brings new challenges to the anesthesiologist. Better understanding of emerging interventional techniques is key to safe practice and allows the anesthesia expert to be at the forefront of this swiftly expanding multidisciplinary arena.

The coexistence of pleural and pericardial effusions in frail patients with or without confirmed neoplasia necessitates the use of a minimally invasive technique that has a minor impact on the patient's general status and allows for fast fluid evacuation and biopsy sampling if necessary. We present a subxiphoid mediastinoscopic autonomous (simultaneous noncommunicating) double fenestration approach for these patients with both diagnostic and therapeutic advantages in selected cases. Using the mediastinoscope alone through the subxiphoid incision can considerably reduce the duration of operation, allow for fluid evacuation, and significantly alleviate the patient's symptoms. This method enables the sampling of pleural and pericardial fluids and targeted tissue, if necessary.

Northeast India, a region of geographic, cultural, and ethnic diversity comprises of Assam, Arunachal Pradesh, Manipur, Meghalaya, Mizoram, Tripura, and Sikkim. Geographically, two-thirds of the area is hilly terrain. The North Eastern Region (NER) shows marked diversity in customs, cultures, cuisines, traditions, and languages. The Aizawl district of Mizoram (269.4) and the Papumpare district of Arunachal Pradesh (219.8) have the highest age-adjusted incidence rates (AAR) of cancer among males and females, respectively. Meghalaya has the highest relative proportion of cancers associated with tobacco use, with 70.4% in men and 46.5% in women. This correlates with the high prevalence of tobacco use. The Dr Bhubaneswar Borooah Cancer Institute, Guwahati, was inaugurated in 1973. The Institute currently conducts M.Ch. Surgical Oncology, Head and Neck Oncology and Gynaecologic Oncology, and DM courses in Medical Oncology and Onco-pathology. The year 2019 saw the creation of a high-dose radioisotope therapy ward. Allogenic Bone Marrow Transplantation (BMT) was started in 2021-2022. State Cancer Institute (SCI), Guwahati, houses a medical cyclotron, which is the only one in Northeast India. Assam Cancer Care Foundation (ACCF) is a joint venture between the Government of Assam and the Tata Trusts, with a three-level cancer grid. The Cachar Cancer Hospital and Research Centre (CCHRC) offers holistic, subsidised cancer care to over 4000 new patients every year. North Eastern Indira Gandhi Regional Institute of Health and Medical Sciences (NEIGRIHMS) offers endobronchial ultrasound (EBUS) and mediastinoscopy services, enabling accurate staging of lung cancers. While the cancer care facilities in NER have grown over the years, it is not commensurate with the high incidence of cancers in the region.

BACKGROUND
Accurate mediastinal staging of lung cancer patients is critical for determining appropriate treatment. Mediastinoscopy and endobronchial ultrasound (EBUS)-guided transbronchial needle aspiration are the most commonly utilized techniques. Limited data exist on training and practice trends among thoracic surgeons. We aimed to determine training and practice patterns and find whether there is a paradigm shift in mediastinal staging after the introduction of EBUS into practice among thoracic surgeons in the United States.
METHODS
28-question survey was constructed querying demographic, training, and practice patterns with mediastinoscopy and EBUS and was sent to practicing thoracic surgeons in the United States. Descriptive statistics were used to summarize quantitative data.
RESULTS
Ninety-eight responded with a 93% completion rate. Eighty-seven percent of respondents received training in EBUS and 70% perform EBUS routinely. All respondents believe EBUS should be incorporated into thoracic surgery training curriculums. Majority of those who prefer EBUS feel EBUS is safer than mediastinoscopy, allows access to lymph nodes stations or lesions inaccessible by mediastinoscopy and prefer EBUS to avoid re-do mediastinoscopy and in irradiated mediastinum. Majority of those who prefer mediastinoscopy reported they perform more accurate staging compared to EBUS, that mediastinoscopy is more accurate in diagnosing lymphoma or sarcoidosis and that frozen section can be done at the same interval as resection. Among surgeons who prefer EBUS, 94% biopsy 3 or more lymph node stations, 86% routinely biopsy hilar (N1) nodes while 8% never biopsy N1 nodes. Of surgeons who prefer mediastinoscopy. Ninety-seven percent biopsy 3 or more lymph node stations, only 27% routinely biopsy N1 nodes and 70% never biopsy N1 nodes.
CONCLUSIONS
EBUS is used frequently by thoracic surgeons in their practice for mediastinal staging. Methods of obtaining proficiency in EBUS widely varied among surgeons. In addition to mediastinoscopy, dedicated EBUS training should be incorporated into thoracic surgery training curriculums.

Review
The staging of mediastinal lymph nodes for lung cancer is crucial for planning treatments or reinterventions. In potentially curable patients the aim of mediastinal staging is to exclude the presence of malignancy in mediastinal lymph nodes with a high level of accuracy while also considering clinical factors and the balance of the benefits and risks of tissue sampling techniques. Mediastinal staging is based on computed tomography (CT) and positron emission tomography (PET) and can be sufficient when no mediastinal abnormalities are present and the probability of unforeseen N2 disease is low. In the case of bulky lymph nodes with a high probability of malignancy in PET-CT, tissue confirmation is not normally required. If mediastinal sampling is needed it can be achieved by endosonographic techniques, including endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) and endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) or a combination of the two. Positive results do not need further confirmation. In the case of negative results, surgical techniques still play a role in the selected cases discussed by multidisciplinary lung cancer committees. New mediastinal surgical techniques including video-assisted cervical mediastinoscopy (VACM), video-assisted mediastinoscopic lymphadenectomy (VAMLA), and transcervical extended mediastinal lymphadenectomy (TEMLA) have been shown to be useful in selected patients. Final pathological staging is based on lymph node removal during surgery and can be achieved by taking one of two approaches: lymph node sampling or systematic lymph node sampling. The accuracy of PET-CT and mediastinal endosonography is lower for mediastinal restaging than it is for surgical techniques; their false positive and false negative (FN) rate is high and so, they require histological confirmation. Here we explain and revise the results from the most recent studies and current international guidelines.

Polish Archives of Internal Medicine Aug 2021Tuberculosis is frequently omitted in the diagnostic workup and may be identified accidentally following thoracic surgeries, mostly those targeting lung cancer.
INTRODUCTION
Tuberculosis is frequently omitted in the diagnostic workup and may be identified accidentally following thoracic surgeries, mostly those targeting lung cancer.
OBJECTIVES
This study aimed to assess the clinical characteristics of patients who underwent thoracic surgery that resulted in the diagnosis of tuberculosis and to review lesions initially found on chest imaging in the context of the potential presence of tuberculosis.
PATIENTS AND METHODS
We analyzed medical records of all patients hospitalized at the Department of Thoracic Surgery of the National Tuberculosis and Lung Diseases Research Institute, Warsaw, Poland, between the years 2014 and 2018 (n = 57) in whom tuberculosis was diagnosed. Two radiologists who knew the diagnosis retrospectively analyzed preprocedural chest computed tomography scans of the study patients.
RESULTS
Tuberculosis was diagnosed by culture of specimens obtained during video‑ assisted thoracoscopy (21 patients), thoracotomy (24 patients), mediastinoscopy (6 patients), transthoracic fine‑ needle biopsy (3 patients), and transbronchial biopsy (1 patient). In the remaining 2 individuals, the diagnosis was established based on the microbiological examination of drained pleural fluid. In 42 patients (73.7%), the diagnosis of tuberculosis was unexpected to thoracic surgeons. Radiological findings suggestive of tuberculosis were present in 38 patients (66.7%). The radiologists who retrospectively analyzed the imaging records suggested tuberculosis in 31 persons (54.3%), whereas those who carried out the initial preprocedural evaluation, in 11 (19.3%).
CONCLUSIONS
The majority of the study patients presented with radiological findings encountered in tuberculosis, which should have led to a less invasive diagnostic workup. This highlights the role of radiologists in the identification of the disease.

Review
The staging of mediastinal lymph nodes is essential for planning the most adequate treatment for patients with non-small cell lung cancer (NSCLC). For this reason, the current American and European guidelines recommend obtaining tissue confirmation of any mediastinal abnormality seen on chest computed tomography (CT) and positron emission tomography (PET). This can be done by endoscopic techniques, such as endobronchial ultrasonographic fine-needle aspiration (EBUS-FNA), esophageal ultrasonographic FNA (EUS-FNA), or a combination of the two (CUS). Traditionally, surgical methods have been reserved to validate the negative results of minimally invasive endoscopic techniques. However, based on the latest evidence, cervical mediastinoscopy and video-assisted mediastinoscopic lymphadenectomy (VAMLA) have demonstrated their superiority over minimally invasive methods in terms of performance for those tumors with normal mediastinum [clinical (c) N0-1 by CT and PET]. Therefore, cervical mediastinoscopy and VAMLA should be considered in the staging algorithms of this particular subset of NSCLC, and in the other well-established indications.

Anthracosis is an environmental lung disease caused by carbon deposition and pigmentation in the airways. However, in rare instances, it can also have systemic involvement. We present a patient with B-symptoms and diffuse lymphadenopathy who was diagnosed with the infrequently described nodal anthracosis. A 64-year-old Vietnamese gentleman with a 50-pack-year smoking history who was recently diagnosed with prostate cancer post-radical prostatectomy and awaiting radiation therapy presented with generalized weakness, low-grade fever, night sweats, and unquantifiable weight loss for a month. He was hemodynamically stable, and examination revealed bilateral inguinal and axillary lymphadenopathy. Computed tomography (CT) showed diffuse lymphadenopathy involving the mediastinum, hilar, axillary, mesenteric, retroperitoneal, and bilateral iliac chains with multiple diffuse pulmonary nodules. Laboratories disclosed anemia, thrombocytopenia, elevated erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP), albumin-globulin (A-G) reversal, and sterile blood cultures. The disseminated intravascular coagulation panel was negative with normal fibrinogen and mildly elevated D-dimer. Autoimmune workup, including antinuclear antibody (ANA), was negative. Infectious workup included , , , Lyme serology, QuantiFERON-TB Gold, HIV, and hepatitis panel, and all were negative. He was managed with broad-spectrum antibiotics, which were discontinued after a negative infectious workup. He also complained of a new-onset holocranial headache with no features of meningitis; an MRI with contrast revealed focal occipital leptomeningeal involvement and cerebral edema with occipital lymphadenopathy. A lumbar puncture was planned but deferred at the patient's request. An excisional lymph node biopsy of the left axillary lymph node revealed reactive follicular hyperplasia with no evidence of malignancy, with flow cytometry negative for any evidence of B- or T-cell malignancies. He continued to have persistent low-grade fevers. A bone marrow biopsy showed 70% cellularity with paratrabecular interstitial lymphoid aggregates composed of both T and B cells, which was nonspecific, and flow cytometry could not be done due to dry tap. An F-18-fluorodeoxyglucose positron emission tomography (FDG PET) scan showed extensive hypermetabolic disease both above and below the diaphragm with bulky mediastinal adenopathy and splenomegaly. Subsequently, he underwent a mediastinoscopy and biopsy of the mediastinal lymph nodes, which demonstrated reactive hyperplasia and abundant anthracitic pigment on microscopic examination, consistent with the diagnosis of nodal anthracosis. He was managed conservatively, discharged, and found to have spontaneously resolved symptoms at a six-week follow-up. Nodal anthracosis with PET-positive mediastinal and hilar lymphadenopathy is a rare presentation of anthracosis that mimics infectious conditions, granulomatous diseases, and malignancies. The pigment deposition can cause persistent inflammatory activity and should be considered an infrequent but important explanation of lymphadenopathy in patients without known biomass exposure.

Review
Sarcoidosis is a highly variable granulomatous multisystem syndrome. It affects individuals in the prime years of life; both the frequency and severity of sarcoidosis are greater in economically disadvantaged populations. The diagnosis, assessment, and management of pulmonary sarcoidosis have evolved as new technologies and therapies have been adopted. Transbronchial needle aspiration guided by endobronchial ultrasound has replaced mediastinoscopy in many centers. Advanced imaging modalities, such as fluorodeoxyglucose positron emission tomography scanning, and the widespread availability of magnetic resonance imaging have led to more sensitive assessment of organ involvement and disease activity. Although several new insights about the pathogenesis of sarcoidosis exist, no new therapies have been specifically developed for use in the disease. The current or proposed use of immunosuppressive medications for sarcoidosis has been extrapolated from other disease states; various novel pathways are currently under investigation as therapeutic targets. Coupled with the growing recognition of corticosteroid toxicities for managing sarcoidosis, the use of corticosteroid sparing anti-sarcoidosis medications is likely to increase. Besides treatment of granulomatous inflammation, recognition and management of the non-granulomatous complications of pulmonary sarcoidosis are needed for optimal outcomes in patients with advanced disease.
