Transient Aphonia After Mediastinoscopy

The role of mediastinoscopy in the diagnosis of non-lung cancer diseases

BACKGROUND

Mediastinoscopy is a good method to evaluate mediastinal lesions. We sought to determine the current role of mediastinoscopy in the investigation of non-lung cancer patients with mediastinal lymphadenopathy.

MATERIALS AND METHODS

We retrospectively reviewed clinical parameters (age, gender, histological diagnosis, morbidity, mortality) of all patients without lung cancer who consecutively underwent mediastinoscopy in Hospital of Faculty of Medicine of Dicle University between June 2003 and December 2016.

RESULTS

Two-hundred twenty nine patients without lung cancer who underwent mediastinoscopy for the pathological evaluation of mediastinum during the study period were included. There were 156 female (68%) and 73 male (32%) patients. Mean age was 52.6 years (range, 16 to 85 years). Mean operative time was 41 minutes (range, 25 to 90 minutes). Mean number of biopsies was 9.3 (range, 5 to 24). Totally, 45 patients (19.6%) had previously undergone a nondiagnostic bronchoscopic biopsy such as transbronchial needle aspiration or endobronchial ultrasound-guided transbronchial needle aspiration. Mediastinoscopy was diagnostic for all patients. Diagnosis included sarcoidosis (n=100), tuberculous lymphadenitis (n=66), anthracosis lymphadenitis (n=44), lymphoma (n=11) metastatic carcinoma (n=5), and Castleman's disease (n=1); there was a diagnosis of silicosis in one patient and tymoma in one patient. Neither operative mortality nor major complication developed. The only minor complication was wound infection which was detected in three patients.

CONCLUSION

Although newer diagnostic modalities are being increasingly used to diagnose mediastinal diseases, mediastinoscopy continues to be a reliable method for the investigation of mediastinal lesions.
