Diagnostic and therapeutic thoracoscopy: lessons from the learning curve

Area of Science:

• Thoracic Surgery
• Minimally Invasive Procedures
• Surgical Technology

Background:

• Video-assisted thoracic surgery (VATS) is increasingly common, yet challenges during its implementation are less documented.
• This study addresses the learning curve and complication rates associated with VATS procedures.

Purpose of the Study:

• To evaluate the outcomes, complications, and hospital stay associated with minimally invasive thoracic surgery.
• To identify risk factors for complications and assess the impact of technological advancements and surgeon experience.

Main Methods:

• A review of 69 consecutive patients undergoing minimally invasive thoracic procedures over 27 months.
• Analysis of conversion rates to thoracotomy, complication frequencies, and postoperative hospital stay.
• Logistic regression was used to identify independent risk factors for complications.

Main Results:

• Diagnostic VATS procedures had higher conversion rates (33%) and fewer complications (20%) compared to therapeutic interventions (5% conversion, 50% complications; p=0.01).
• Chronic obstructive pulmonary disease (COPD) was an independent risk factor for complications.
• Mean hospital stay was significantly shorter for diagnostic (7.9 days) versus therapeutic (12.8 days) interventions (p=0.02) and decreased over time with technological improvements.

Conclusions:

• While VATS is promising, careful surgical judgment and expertise are crucial for managing thoracic complications.
• Therapeutic VATS procedures are associated with higher complication rates and longer hospital stays than diagnostic ones.
• Technological advancements and surgeon experience significantly influence outcomes and reduce hospital stay.
