INTRODUCTION: Cervical mediastinoscopy can provide a minimally invasive access to the paratracheobronchial mediastinum within its reachable range, but its operability is substantially limited because of its small operative field, poor visualisation, and one-handed operation. PRESENTATION OF CASES: Patient 1, a 56-year-old woman, presented with a 22×17mm, non-symptomatic, (18)F-fluorodeoxy glucose (FDG)-avid, solid schwannoma originating from the vagus nerve trunk in the right upper paratracheal space...

BACKGROUND: The aim of this study was to evaluate the results of video-assisted mediastinoscopic lymphadenectomy (VAMLA) for staging of non-small cell lung cancer (NSCLC). METHODS: This was a prospective observational study of all consecutive VAMLAs performed from January 2010 to April 2015 for staging NSCLC. For left lung cancers, extended cervical videomediastinoscopy was added to explore the subaortic and paraaortic nodes. Patients with negative VAMLA results underwent tumor resection and lymphadenectomy of the remaining nodes...

We herein describe a single-port mediastinoscopic method for upper mediastinal dissection in esophageal cancer surgery. After the left cervical incision and lymphadenectomy, a Lap-Protector (Hakko, Tokyo, Japan) was inserted into the wound and an EZ Access port (Hakko) was attached. Esophageal mobilization with en bloc lymphadenectomy along the left recurrent laryngeal nerve was then performed using a port-in-port technique with conventional flexible laparoscopy. Carbon dioxide insufflation expanded the intramediastinal space, and minute structures in the deep mediastinum around the aortic arch, such as nerves, bronchial arteries, and lymphatic vessels, were clearly visualized, allowing lymphadenectomy to be safely and carefully performed along the nerve...

Pericardial effusion may be associated with many diseases, but sometimes its aetiology is not easy to elucidate. Subxiphoid video-pericardioscopy is useful for the study of the pericardial cavity. Through a subxiphoid approach, the pericardium is incised and a rigid (usually a video-mediastinoscope) or a flexible endoscope (flexible bronchoscope or flexible choledoscope) is inserted into the pericardial cavity. The inner surface of the parietal pericardium and the epicardium can be explored and biopsies can be taken under visual control...

CASE: An eighty year old African-American female was evaluated for cough, chest pain, asymptomatic anemia and 21 pound weight loss over a six month period. Computerized tomography (CT) revealed a spiculated 2.8 cm right upper lobe lung nodule, other smaller nodules and lymphadenopathy. Gallium scan revealed abnormal uptake of radiotracer in lacrimal, hilar and mediastinal glands. Broncho-alveolar lavage showed CD4/CD8 ratio of 2:1 with 15% lymphocytes. Biopsy of right upper lobe lesion and mediastinoscopic lymph node biopsy showed numerous matured uniform non-caseating granulomatous inflammation, however stains and culture for Acid fast bacilli (AFB)/fungal organisms were negative...

The use of mediastinal surgery for minimally invasive esophagectomy (MIE) has been proposed; however, this method is not performed as radical surgery because it has been thought to be impossible to perform complete upper mediastinal dissection, including the left tracheobronchial lymph nodes (106tbL). We herein describe a new method for performing complete dissection of the upper mediastinum. We developed a method for performing complete mediastinoscopic esophagectomy as radical surgery via the bilateral transcervical and transhiatal approach in 6 Thiel-embalmed human cadavers...

BACKGROUND: Extended thymectomy is indicated for children with myasthenia gravis (MG) when drug-resistance or dependence is seen. We have employed a technique for mediastinoscopic extended thymectomy (MET) on children with MG. METHOD: A total of 14 children underwent MET at Kanagawa Children's Medical Center between 2005 and 2013. A mediastinal operation field was made by a V-shaped hook infrasternally to extirpate the thymus with adipose tissue around the thymus...

Bilateral pulmonary nodules represent a challenge in distinguishing between synchronous bronchogenic carcinomas and metastatic disease. In the case of potentially curable synchronous lung cancer, it is recommended to treat each lesion with curative intent if there is no evidence of mediastinal involvement or extrathoracic disease. In this situation, surgical staging of the mediastinum is recommended. This case shows the utility of a transcervical approach to perform precise mediastinal staging and lymphadenectomy, and to access the pleural cavity to resect a pulmonary nodule...

OBJECTIVES: Although video-assisted mediastinoscopic lymphadenectomy (VAMLA) has greatly increased the accuracy of mediastinal staging, its clinical value as a therapeutic tool for complete mediastinal lymph node dissection in the treatment of left-sided lung cancer is not well elucidated. METHODS: We identified the consecutive 649 patients with left-sided lung cancer undergoing minimally invasive pulmonary resection between July 2002 and June 2013. Among them, 225 patients underwent VAMLA combined with pulmonary resection (VAMLA + VATS group), while the remaining 424 patients underwent VATS procedure only (VATS group)...

Accurate lymph nodal staging of lung cancer is critical for determining the treatment options. With the help of (18)F-fluorodeoxyglucose positron emission tomography/computer tomography ((18)F-FDG-PET/CT), the clinician can rule out/in the regional lymph nodes positive for metastasis in the patients with lung cancer in a majority of cases. However, a small proportion of cases with false positivity of metastasis have been reported. Transbronchial needle aspirations and mediastinoscopic biopsies are still necessary to determine whether enlarged hypermetabolic mediastinal lymph nodes are positive for lung cancer metastasis...

The main prerequisite for the unimpaired wound healing after resection of tracheal stenosis is its tension-free end-to-end anastomosis. This is only achievable when the tracheal ends can be adequately mobilized. Several mobilization techniques have been described in the literature. Here, the authors describe a case of tracheal mobilization under video mediastinoscopic assistance that displayed a considerable advantage over blunt mobilization and a length gain of over 3 cm.

Takayasu's arteritis (TA) is a rare chronic large-vessel vasculitis. The early diagnosis is difficult, because of lack of characteristic clinical manifestations. In this paper, we reported a TA case of young female was misdiagnosed as mediastinal malignant lymphoma and mediastinoscope biopsy was performed. The biopsy result demonstrated that thickened tissue adjacent to the aortic arch pathological presentations were in accord with TA. Glucocorticoid was administrated and the condition was greatly improved after treatment...
