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.

Completely video-assisted thoracoscopic lobectomy versus open lobectomy for non-small cell lung cancer greater than 5 cm：a retrospective study

Background Completely video-assisted thoracoscopic Iobectomy is a reasonable treatment for early-stage non-small-cell lung cancer （NSCLC）.At present,the indication for this procedure is stage la and Ib peripheral lung cancer （（〈-）5 cm）; however,for larger tumors,it remains controversial whether this surgical technique is comparable to open Iobectomy.This study aimed to evaluate the safety,completeness,and efficacy of thoracoscopic Iobectomy,and to compare this technique with open Iobectomy for the treatment of non-small-cell lung cancer when the tumor＇s diameter was greater than 5 cm.Methods From May 2001 to April 2011,802 patients underwent a Iobectomy for treatment of non-small-cell lung cancer at our center.In 133 patients,the tumor was 〉 5 cm.There were 98 men and 35 women,median age 63 years （range：29-81 years）.We divided the patients into two groups,group V （completely video-assisted thoracoscopic surgery）,and group T （open Iobectomy）,and evaluated the two groups for age,gender,tumor size,pathological type,location,duration of surgery,blood loss,lymph node dissection,pathological stage,time of drainage,hospitalization,complications,overall survival and recurrence.Results There were 46 cases in group V and 87 cases in group T.Age,gender,tumor size,location,pathological type and stage were similar between the two groups.Group V had shorter operative duration （（186.5±62.8） minutes vs.（256.7±67.5） minutes,P 〈0.001） and reduced bleeding （（218.5±174.6） ml vs.（556.9±187.2） ml,P 〈0.001）.There were no significant differences between the two groups in complications,lymph node dissection,time of drainage and hospitalization.The recurrence between the two groups was equivalent （2.4% vs.3.8%,P=0.670）.The overall survival at 1,2 and 3 years was 95.1%,81.6% and 69.6% for group V and 88.3%,78.8% and 64.0% for group T.Kaplan-Meier survival curves showed that there was no significant differences between the two groups （P=0.129）.Conclusions Completely video-assisted thoracoscopic lobectomy was similar to open lobectomy in safety,completeness,and efficacy,but had a shorter operative duration,and reduced bleeding.This is a minimally invasive procedure that is feasible for a subset of non-small-cell lung cancer patients with tumor size 〉 5 cm.
