Robot-assisted thoracic surgery (RATS) offers improved lymph node yield and potentially shorter operative times compared to video-assisted thoracoscopic surgery (VATS) for lung cancer resection. RATS demonstrates superior oncologic outcomes and safety.

Area of Science:

Thoracic Surgery
Surgical Oncology
Minimally Invasive Surgery

Background:

Lung resection is a cornerstone treatment for lung cancer.
Video-assisted thoracoscopic surgery (VATS) is a common minimally invasive approach.
Robot-assisted thoracic surgery (RATS) represents an advancement in minimally invasive techniques.

Purpose of the Study:

To systematically review and compare the clinical outcomes of RATS versus VATS in lung resection.
To evaluate the safety and efficacy of RATS in oncologic lung surgery.

Main Methods:

A systematic review and meta-analysis of studies from PubMed, ClinicalTrials.gov, and Cochrane Library.
Inclusion of 29 studies with 66,406 patients.
Analysis of primary outcomes: lymph node yield and operative time; secondary outcomes: R0 resection, complications, and recurrence.

Keywords:

lung lymph nodes neoplasms odds ratio postoperative complications robotic surgery

Main Results:

RATS demonstrated a significantly higher lymph node yield (MD 4.54; 95% CI 2.91-6.17).
RATS was associated with a trend towards shorter operative time (MD -6.09; 95% CI -13.20-1.03).
RATS showed higher R0 resection rates, fewer postoperative complications, and lower recurrence rates.

Conclusions:

Robot-assisted thoracic surgery (RATS) is a safe and oncologically effective approach for lung resection.
Findings support the adoption of RATS for improved patient outcomes in lung cancer surgery.
