The mediastinum is the area in the middle of the chest between the lungs. A mediastinotomy is the creation of a small opening in the upper chest into the mediastinum. This opening allows the doctor to examine the area between and in front of the lungs.

Reasons for Procedure

This procedure is done to examine the lungs and chest. Your doctor might take tissue samples ( biopsy ). These samples are examined under a microscope to check for diseases like:

  • Cancer of the lungs , bronchi, and chest tissue
  • Lymphoma—cancer in the lymphatic system, such as Hodgkin’s disease
  • Infection
  • Inflammation
  • Sarcoidosis —a condition that causes inflammation in organs like the lungs, liver, lymph nodes, and spleen

Mediastinotomy is also done to find out if lung cancer has spread.

Possible Complications

Problems from the procedure are rare, but all procedures have some risk. Your doctor will review potential problems, like:

  • Bleeding
  • Infection
  • Hoarseness
  • Chylothorax—leakage of lymphatic fluid into the chest
  • Damage to organs in the chest
  • Pneumothorax (collapsed lung)

Before your procedure, talk to your doctor about ways to manage factors that may increase your risk of complications such as:
