Abstract
Background: Mediastinoscopy is the gold standard procedure for the pathological staging and diagnosis of mediastinal diseases. The aim of the study is to describe the significance of anterior cervical Mediastinoscopy in evaluating patients with mediastinal lymphadenopathy and lung parenchymal disease. Material and Methods: From January 2014 until June 2017 we conducted a retrospective study of 52 consecutive patients with mediastinal lymphadenopathy and lung parenchymal disease who underwent anterior cervical Mediastinoscopy. The main indications for cervical Mediastinoscopy were isolated mediastinal lymphadenopathy, undetermined lung mass with mediastinal lymphadenopathy, and the clinical staging of patients with lung cancer. Results: The study subjects consisted of 37 men and 15 women, aged 13 to 87 (mean age 50.8). Eight patients had mediastinoscopy for staging lung cancer, 27 patients had mediastinoscopy to diagnose isolated mediastinal lymphadenopathy, and 17 patients had mediastinoscopy for an undetermined lung parenchymal mass. Among the patients with isolated mediastinal lymphadenopathy, sarcoidosis was diagnosed in 6, tuberculosis in 9, reactive lymph nodes in 4, metastasis in 5 and lymphoma in 3. Lymph node metastasis (N2, N3) was found in 5 patients with lung cancer. There was no surgical-related mortality or morbidity. Conclusions: Mediastinoscopy is a safe and reliable procedure in diagnosing mediastinal diseases and is still the first choice among the investigative modalities in the clinical staging of bronchogenic carcinoma.
Highlights
Non-invasive approaches, such as computed tomography (CT) integrated with positron emission tomography (PET), have caused thoracic surgeons to doubt the importance of cervical mediastinoscopy in the clinical diagnosis of mediastinal masses and the staging of lung cancer
In patients with isolated mediastinal lymphadenopathy, we found the cervical mediastinoscopy sensitivity, specificity, and negative predictive value was 100%
Kasufuku and colleagues undertook a prospective controlled trial involving 159 patients and compared EBUS-TBNA with mediastinoscopy as staging modalities for assessing mediastinal lymph nodes in patients with lung cancer; they indicated the superiority of mediastinoscopy for sampling lymph node stations 2R and 2L, there was no significant difference in determining the true pathologic mediastinal lymph node stage
