Pharyngolaryngoesophagectomy using the thoracoscopic approach

Area of Science:

• Thoracic surgery
• Surgical oncology
• Gastrointestinal surgery

Background:

• Pharyngolaryngoesophagectomy involves complex esophageal dissection.
• Thoracoscopic mobilization allows direct visualization, potentially improving safety.
• Transhiatal mobilization is the conventional approach.

Purpose of the Study:

• To evaluate the safety and efficacy of thoracoscopic esophageal mobilization.
• To investigate the existence of a learning curve and its impact on outcomes.
• To compare early versus later patient outcomes.

Main Methods:

• A retrospective review of 57 patients undergoing pharyngolaryngoesophagectomy.
• Comparison of outcomes between the first 30 and last 27 patients.
• Prospective documentation of intraoperative events and postoperative outcomes.

Main Results:

• Significantly reduced blood loss in the later group (400 ml vs. 700 ml).
• No significant differences in thoracoscopic time, pulmonary complications, atrial arrhythmia, hospital mortality, or 2-year survival rates.
• Pulmonary complications occurred in 40% of the first group and 48% of the second group.

Conclusions:

• Subjective improvement in surgical skills was noted over time.
• No clear demonstration of improved outcomes in the latter half of the series.
• Prior extensive experience of surgeons likely mitigated the learning curve effect.
