Laparoscopic oesophagogastrectomy using carbon dioxide insufflation in the thorax avoids thoracotomy but can cause significant hemodynamic and respiratory changes. Careful insufflation and lung management are crucial to minimize risks like pneumothorax.

Area of Science:

  • Thoracic Surgery
  • Minimally Invasive Procedures
  • Surgical Physiology

Background:

  • Thoracotomy is traditionally required for oesophageal dissection during oesophagogastrectomy.
  • Laparoscopic techniques offer potential patient benefits by avoiding open chest surgery.

Purpose of the Study:

  • To evaluate the feasibility and physiological impact of laparoscopic thoracic and cervical oesophageal dissection.
  • To identify and suggest methods for mitigating adverse hemodynamic and respiratory changes during this procedure.

Main Methods:

  • Ten patients underwent laparoscopic oesophagogastrectomy with thoracic and cervical oesophageal dissection.
  • Right lung collapse was achieved using a double-lumen bronchial tube.
  • Carbon dioxide was insufflated into the right pleural cavity to facilitate surgical access.

Main Results:

  • Increased airway pressure and end-tidal CO2 were observed in most patients.
  • Hypotension occurred in 50% of patients, and hypoxemia (SpO2 ≤91%) in 40%, despite high FIO2.
  • Complications included tension pneumothorax, surgical emphysema, contralateral pneumothorax, and recurrent laryngeal nerve damage.

Conclusions:

  • Laparoscopic oesophagogastrectomy with thoracic CO2 insufflation is feasible but associated with significant physiological disturbances.
  • Strategies to optimize CO2 insufflation rate and ensure adequate lung deflation are necessary to improve patient safety.
