Mediastinoscopic ultrasonography (MUS).

چکیده
Correct pre-therapeutic T4 staging is mandatory for neo-adjuvant studies and for the decision on surgical therapy of high-risk patients. T4-staging of centrally located lung-cancer by means of non-invasive imaging techniques is either of low accuracy (CT and NMR) or important regions are not accessible due to air interference with the tracheo-bronchial tree (trans-esophageal-endosonography, TEE). We here describe for the first time the new technique of mediastinoscopic ultrasonography (MUS). A fingertip ultrasound probe is introduced through the video-mediastinoscope. The probe lies in front of the tracheo-bronchial tree and in direct contact with the vena cava and pulmonary artery. This position allows examining those regions that are not accessible with TEE. In a pilot study with 12 patients, visualization of central vessels and their relation to the tumor was excellent and without artifacts. In 3 patients, MUS did not confirm the T4 stage predicted by CT Scan. Those three patients underwent successful pneumonectomy (R0-resection) while the other nine patients received induction treatment. MUS is a promising addition to CT scanning, NMR, and transesophageal ultrasound in staging of centrally located tumors.

Clinical feasibility and surgical benefits of video-assisted mediastinoscopic lymphadenectomy in the treatment of resectable lung cancer.
OBJECTIVE This study was performed to assess the clinical feasibility and surgical outcomes of video-assisted mediastinoscopic lymphadenectomy in the treatment of resectable lung cancer. METHODS Between July 2004 and December 2009, we retrospectively analyzed 108 consecutive video-assisted mediastinoscopic lymphadenectomies in lung cancer patients from a prospectively collected database. Nine...
متن کاملVideo-assisted mediastinoscopic transhiatal esophagectomy combined with laparoscopy for esophageal cancer
BACKGROUND Minimally invasive transhiatal esophagectomy for esophageal cancer includes mediastinoscopic and laparoscopic transhiatal esophagectomy. It is inadequate in both two techniques. It is impossible to dissect the lower esophagus with single mediastinoscopy or the upper and middle esophagus with single laparoscopy. We use mediastinoscopy combined with laparoscopy to dissect the whole eso...
متن کاملTransient unilateral hypoperfusion of the lung following mediastinoscopy.
Two cases of pulmonary hypoperfusion occurring after mediastinoscopic examination were demonstrated on lung scans. In one case, this finding on the ninth day required a pulmonary angiographic study that yielded normal findings. Repeat lung scans were normal. We propose that localized mediastinal edema or bleeding after mediastinoscopic examination can produce defects of hypoperfusion, and we ur...
متن کاملDetection of disseminated tumor cells in mediastinoscopic lymph node biopsies and lymphadenectomy specimens of patients with NSCLC by quantitative RT-PCR.
OBJECTIVE Detection of disseminated tumor cells in mediastinoscopic biopsies could improve staging and might be helpful concerning indications for neoadjuvant therapy regimens. This prospective study was performed to evaluate a simple and observer-independent polymerase chain reaction (PCR)-based method for the detection of disseminated tumor cells in regional lymph nodes. METHODS Lymph nodes...
متن کاملMusculoskeletal ultrasonography: what is it and should training be compulsory for rheumatologists?
The role of musculoskeletal ultrasonography (MUS) in rheumatology is evolving rapidly [1, 2]. No longer is it restricted to the detection of Baker’s cysts or deep venous thromboses. MUS has become a sophisticated tool for the assessment of patients with a range of rheumatic diseases from inflammatory arthritis to vasculitis and soft tissue rheumatism [3]. The potential benefits to patients and ...
