Lung-Pro Guided Disposable Lung Surgery Markers For Localization Of Pulmonary Nodules Under Thoracoscopy

ObjectiveTo evaluate the safety and effectiveness of Lung-Pro-guided disposable lung surgical marker positioning in thoracoscopic resection of small pulmonary nodulesMethod:A total of 70 patients with single small lung nodules who underwent single-port thoracoscopic wedge resection in our hospital from May 2020 to March 2021 were collected.According to the order of admission,they were randomly divided into two groups:35 cases The Lung-Pro-guided disposable lung surgical markers were used as the Lung-Pro group,and the 35 patients who underwent CT-guided Hook-wire puncture positioning were used as the puncture group.After positioning,the two groups of patients underwent pulmonary wedge resection.As a result,determine the next step of treatment.Collect the general data of the two groups of patients,such as gender,age,nodule location,nodule size,distance from the nodule to the pleura,pathological type,previous tumor history,etc.,as well as surgery and postoperative related information,such as positioning time,positioning success rate,Differences in the time of lung wedge resection,the number of staple cartridges used in the operation,the amount of blood loss during the operation,the complications after positioning,the complications after the operation,and the length of hospital stay after the operation.To evaluate the safety and effectiveness of Lung-Pro-guided disposable lung surgical marker positioning and CT-guided puncture positioning in thoracoscopic resection of small pulmonary nodules.ResultThere were no statistically significant differences between the two groups of patients in terms of gender,age,nodule location,nodule size,distance from the nodule to the pleura,pathological type,and past tumor history(P>0.05).The success rate of localization in the Lung-Pro group was 94.3%.Two patients were recorded as localization failure because the distance between the lesion and the marker was greater than 2cm,but the lesion was successfully removed and ensured to be within the safe margin.The positioning success rate in the puncture group was 88.6%,and 4 patients had decoupling.Among them,2 patients found the nodules based on the bleeding of the lung parenchyma after the positioning hook fell off and successfully removed the nodules.The other 2 patients were due to the distance of the resection margin after wedge resection Supplementary resection is performed for nodules less than 2cm.In terms of positioning time,the Lung-Pro group was shorter than the puncture group(10.9±8.5 VS 20.2±4.4),which was statistically significant;the Lung-Pro group did not record positioning-related complications,while the puncture group showed pain after positioning Complications such as pneumothorax,hemorrhage,etc.;in terms of lung wedge resection time,the Lung-Pro group was shorter than the puncture group(16.4±8.9 VS 20.4±6.6),which was statistically significant.Positioning success rate(P=0.673),number of staple cartridges used in operation(P=0.098),intraoperative blood loss(P=0.287),postoperative complications(P=1.00),postoperative hospital stay(P=0.167)None were statistically significant.Conclusion:1.Lung-Pro’s disposable lung surgery marker positioning and CT-guided puncture positioning are both safe and effective positioning methods.2.Compared with CT-guided hook-wire puncture positioning,the Lung-Pro-guided disposable lung surgical marker positioning method is safer,has fewer complications,and is shorter in positioning time and lung wedge resection.
