Pdf Summary

The study compares early surgical outcomes and changes in lung function between complex basal segmentectomy and lower lobectomy. Complex basal segmentectomy is considered more challenging due to anatomical complexities and potential postoperative complications, which often results in its preference being questioned. The study aims to analyze perioperative outcomes and lung function changes in patients undergoing these two procedures.<br /><br />The research involved 68 patients undergoing complex basal segmentectomy and 148 undergoing lower lobectomy. Key findings indicated significant differences in age and surgical indications between the two groups. Lower lobectomy was more frequently associated with primary lung cancer, whereas complex segmentectomy had more cases of metastatic cancer and benign diseases.<br /><br />Findings showed that patients who underwent complex basal segmentectomy had better early surgical outcomes compared to those who had a lower lobectomy. The segmentectomy involved a notably lesser extent of mediastinal lymph node dissection, reduced number of lymph nodes dissected, and fewer subsegments resected compared to lobectomy. The complex segmentectomy group also experienced reduced operative blood loss, shorter chest tube duration, and reduced postoperative hospital stay.<br /><br />Complication rates were significantly lower in the segmentectomy group, with lower rates of air leakage, pneumonia, and other complications. In terms of lung function, complex basal segmentectomy preserved lung function better postoperatively, showing better outcomes in pulmonary function tests, such as FEV1, FVC, and DLCO, over a 12-month period.<br /><br />The study concludes that despite the inherent challenges of complex basal segmentectomy, it results in better early postoperative outcomes and preserves lung function more effectively than lower lobectomy. Future studies with more data and long-term follow-up are recommended to verify these findings and assess oncological outcomes between the two procedures.
