Pdf Summary

This study compared different surgical approaches for obese patients undergoing anatomical lung resection for early-stage non-small cell lung cancer. The three approaches analyzed were Robotic-assisted (RATS), Video-assisted (VATS) thoracic surgery, and open approach (OA). The study aimed to evaluate morbidity and mortality rates, technical feasibility, and short-term oncologic outcomes.<br /><br />A total of 279 patients with a Body Mass Index (BMI) greater than 30 kg/m2 were included in the study. The primary outcomes analyzed were post-operative complication rate, length of hospital stay (LOS), length of chest drain (LOD), in-hospital mortality, 30- and 90-day mortality, and estimated intraoperative blood loss (eIBL). Secondary outcomes included conversion rate, lymph node stations harvested, nodal upstaging rate, and operating time.<br /><br />The results showed that both RATS and VATS approaches had significantly lower post-operative complication rates, LOS, and LOD compared to the OA. There were no significant differences in mortality rates between the three groups. RATS had a significantly lower eIBL compared to both VATS and OA. Furthermore, RATS was associated with a lower operating time and a higher median number of overall, N1, and N2 lymph node stations harvested.<br /><br />In conclusion, both VATS and RATS approaches were found to be advantageous for obese patients undergoing anatomical lung resection for early-stage non-small cell lung cancer. These approaches were associated with lower post-operative complications, LOS, and LOD compared to the open approach. RATS specifically had the benefit of lower blood loss and operating time, as well as a higher number of lymph node stations harvested. Overall, these findings suggest that minimally invasive approaches may be preferable for obese patients in this context.
