Study Notes
Cervical Anastomosis
- Utilizes lateral incision; performed in supine position.
- Advantages include avoiding thoracic incision, reducing pulmonary complications, and shortening hospital stay.
- Minimizes pain and complications associated with traditional thoracotomy.
- Disadvantages include poor visualization of esophageal tumors, higher anastamotic leak rates, and increased risk of laryngeal nerve injury.
Intrathoracic Anastomosis
- Permits direct visualization of the upper and thoracic esophagus.
- Allows for comprehensive oncological operations and more extensive lymph node dissection.
- Greater pain associated with thoracotomy and increased risk of cardiorespiratory function compromise.
Thoracic Cavity
- The thoracic cavity is protected by the ribcage and includes structures from cardiovascular, digestive, respiratory, and endocrine systems.
- Anteriorly formed by the sternum; laterally outlined by 12 pairs of ribs; posteriorly supported by 12 thoracic vertebrae.
- Subdivided into right and left pleural cavities, mediastinum, and pericardial cavity.
Mediastinum
- Houses all thoracic viscera except the lungs and includes organs such as the esophagus, trachea, and thymus.
- Contains crucial structures like the vagus nerve, thoracic duct, and lymph nodes.
Blood Supply
- Arterial supply from the internal thoracic artery and aorta; venous drainage through mammary and azygous veins.
- Critical to prevent injury to intercostal nerves during surgery.
Patient Positioning
- Supine position for bronchoscopy; thoracotomy may require lateral or supine positioning based on surgical approach.
- Positioning devices like bean bags and bolsters ensure patient safety.
Instrumentation
- Common instruments for open thoracic surgery include Allison lung retractors and Duval clamps.
- Endoscopic approaches require specialized instruments such as telescopes and cameras; counts must be verified at various stages.
Chest Drainage Systems
- Used to restore negative intrapleural pressure post-surgery; chest tubes facilitate drainage of fluids.
- Water-seal systems may be necessary for persistent air leaks.
Double-Lumen Endotracheal Tube
- Essential for surgeries like lung lobectomy requiring single-lung ventilation.
- Consists of bronchial and tracheal lumens; confirms placement with a bronchoscope.
Rigid Bronchoscopy
- Involves using a rigid bronchoscope for visualizing the trachea and bronchi.
- Procedure may cause anxiety; precautions include inspecting oral integrity pre- and post-operatively.
Mediastinoscopy
- A small incision above the sternal notch allows examination of the mediastinum.
- Awareness of potential complications, such as injury to the brachiocephalic artery, is vital.
Esophagectomy
- Surgical removal and reconstruction of the esophagus; approach determines necessary equipment and patient positioning.
- Involves confirmatory checks for tumor-free margins with intraoperative pathology.
Surgical Approaches
- Transhiatal and transthoracic esophagectomies differ in incisional techniques and patient positioning.
- En bloc esophagectomy utilizes a three-incision approach for comprehensive access.
