Study Notes
Pleural Cavity
- Composed of parietal pleura and visceral pleura, creating a negative intrapleural pressure critical for pulmonary ventilation.
Respiratory Tract Anatomy
- Trachea branches into primary bronchi, secondary bronchi, bronchioles, and alveoli; alveoli are the site of gas exchange.
- Bronchial arteries provide nourishment to lung tissues.
- Bronchi facilitate oxygen intake and carbon dioxide expulsion.
Mediastinal Lymph Nodes
- Important in diagnosing primary lung cancer or metastatic diseases.
Surgical Techniques and Procedures
-
VATS (Video-Assisted Thoracoscopic Surgery):
- Initial and closing counts differ for major and minor surgeries.
- Wedge resection involves removing a tumor or lesion from the lung.
- Lung lobectomy includes mobilizing the pulmonary artery, pulmonary veins, and bronchus, ligated using sutures or stapling devices.
-
Lung Volume Reduction Surgery:
- Targets patients with COPD, particularly chronic pulmonary emphysema, by resecting hyperinflated lung tissue.
-
Double Lumen Endotracheal Tube (ETT):
- Enables single-lung ventilation during procedures like lobectomies.
- Blue bronchial lumen ventilates the non-operative lung, while the white tracheal lumen collapses or deflates the operative lung.
Esophagectomy Techniques
-
Transhiatal Esophagectomy:
- Two-incision approach includes laparotomy (abdominal) and left neck incision.
-
Transthoracic Esophagectomy:
- Can be one or two-stage procedure with lateral thoracoabdominal incision.
- Two-stage involves laparotomy and right thoracotomy.
-
En Bloc (Tri-incisional Esophagectomy):
- Combines thoracotomy and transhiatal approaches with incisions at abdomen, left neck, and right thoracic area.
