Local anesthesia for mediastinoscopy: experience with 450 consecutive cases

Area of Science:

• Thoracic Surgery
• Pulmonary Medicine
• Diagnostic Imaging

Background:

• Mediastinoscopy is a widely used diagnostic procedure for evaluating suspected bronchogenic carcinoma.
• Its role in determining resectability and diagnosing benign conditions remains a subject of discussion.

Purpose of the Study:

• To assess the efficacy and safety of mediastinoscopy, particularly under local anesthesia, in diagnosing lung cancer and benign mediastinal diseases.
• To evaluate the impact of mediastinoscopy in preventing unnecessary exploratory thoracotomies.

Main Methods:

• The study reviewed over 450 cases of cervical mediastinal exploration performed over six years.
• Procedures were primarily conducted under local anesthesia, with a focus on patient outcomes, morbidity, and mortality.

Main Results:

• Mediastinoscopy successfully identified patients with incurable lung cancer, avoiding exploratory thoracotomy.
• The procedure demonstrated high diagnostic success rates for benign diseases.
• The study reported a morbidity rate of 1.1% and no mortality.
• Local anesthesia proved safe and effective for universal application in cervical mediastinal exploration.

Conclusions:

• Mediastinoscopy is a safe and effective procedure for evaluating suspected lung cancer and benign mediastinal conditions.
• Performing mediastinoscopy under local anesthesia is applicable in a wide range of clinical scenarios, offering a valuable alternative when general anesthesia is contraindicated.
• The technique significantly contributes to patient management by preventing unnecessary surgical interventions.
