Efficacy of thoracoscopic anatomical segmentectomy for small pulmonary nodules

BACKGROUND Small pulmonary nodules are tissue shadows and thoracoscopic segmentectomy in China is still at the exploratory stage with limited application.AIM To evaluate the efficacy of thoracoscopic anatomical segmentectomy for small pulmonary nodules.METHODS Medical records of 86 patients with small pulmonary nodules treated at our hospital between August 2016 and October 2019 were retrospectively analyzed;40 cases who underwent thoracoscopic lobectomy were set as a reference group,and 46 cases who underwent thoracoscopic anatomical segmentectomy were set as an observation group.Preoperative and postoperative parameters were measured in both groups,including the percentage of forced expiratory volume in the first second(FEV1%),the percentage of forced vital capacity(FVC%),and the FEV1/FVC ratio(FEV1/FVC).Patients with positive pathological diagnosis received tests for neuron-specific enolase,carbohydrate antigen 125(CA125),CA19-9,and squamous cell carcinoma antigen.Intraoperative bleeding volume,drainage volume,the number of dissected lymph nodes,drainage time,hospital stay,treatment cost,postoperative complications,and postoperative pain condition were compared between the two groups.RESULTS No significant difference was observed in the results of four serum tumor marker(CA125,CA19-9,squamous cell carcinoma antigen,and neuron-specific enolase),the number of dissected lymph nodes,treatment cost,or preoperative pulmonary ventilation index between the two groups.Intraoperative bleeding volume,drainage volume,drainage time,hospital stay,and visual analogue scale score were significantly lower in the observation group(P<0.05).The results of FEV1%,FVC%,and FEV1/FVC were significantly higher in the observation group(P<0.05).CONCLUSION The efficacy of thoracoscopic anatomical segmentectomy and lobectomy for small pulmonary nodules shows no significant difference in terms of lesion removal,but anatomical segmentectomy is less invasive with fewer postoperative complications and less influence on lung function.

Complete Thoracoscopic Segmentectomy and Pulmonary Lobectomy in the Treatment of Small Pulmonary Nodules

Objective:To compare the clinical effect of complete thoracoscopic segmentectomy and pulmonary lobectomy for pulmonary nodules.Methods:In this study,176 patients with pulmonary nodules were treated in Changshu Hospital Affiliated to Nanjing University of Chinese Medicine from January 2019 to June 2021;according to the type of surgery,the patients were divided into group A(complete thoracoscopic segmentectomy)and group B(complete thoracoscopic pulmonary lobectomy),and the clinical effects were analyzed.Results:The intraoperative blood loss,postoperative drainage volume,postoperative hospitalization days,and lung function of patients in group A were significantly better than those in group B(P<0.05),while there was no significant difference in the number of dissected lymph nodes.Conclusion:The clinical effect of complete thoracoscopic segmentectomy for patients with small pulmonary nodules is more significant;it does not only ensure lymph node dissection,but also improve surgical-related indicators and treatment safety as well as speed up the recovery of pulmonary function.Its clinical application value is worthy of key analysis by medical institutions.
