VATS port site recurrence: a technique dependent problem.

Area of Science:

• Thoracic Surgery
• Surgical Oncology
• Minimally Invasive Surgery

Background:

• Video-assisted thoracic surgery (VATS) is a common approach for thoracic malignancies.
• Port site tumor recurrence is a known complication of VATS, but its incidence is not well-established.
• Determining the incidence of port site recurrence after VATS wedge resection is crucial for patient safety and treatment planning.

Purpose of the Study:

• To determine the incidence of port site tumor recurrence after VATS wedge resection for malignancy.
• To evaluate the safety and efficacy of VATS wedge resection in cancer patients.
• To identify factors influencing port site recurrence.

Main Methods:

• Analysis of a prospective VATS database from 1992 to 1996.
• Inclusion of patients undergoing VATS wedge resection for malignancy (excluding pleural biopsy only).
• Parameters analyzed: demographics, surgical technique, and port site recurrences identified via physical exam or CT scan.

Main Results:

• 410 patients underwent VATS wedge resection for malignancy (median age 61).
• Operative mortality was 0.25%.
• With a median follow-up of 25 months for 374 patients, only one port site recurrence (0.26%) was identified.

Conclusions:

• VATS wedge resection is a safe procedure for cancer patients.
• Adherence to oncologic principles, including wide lesion removal and meticulous specimen extraction, results in a low incidence of port site tumor recurrence.
• Conversion to thoracotomy for definitive or extensive cancer operations is a key principle to maintain safety and oncologic outcomes.
