RESUMEN
Background: Few original articles describe the perioperative outcomes of uniportal thoracoscopic segmentectomy using a unidirectional dissection approach. In this retrospective study, we evaluated the feasibility and safety of this procedure. Methods: This study included 119 patients who underwent uniportal thoracoscopic segmentectomy in our department between February 2019 and December 2022. The patients were divided into unidirectional (group U, n = 28) and conventional (group C, n = 91) dissection approach groups. While the dominant pulmonary vessels and bronchi were transected at the hilum without dissecting a fissure in the unidirectional (U) group, the dominant pulmonary artery was exposed and divided at a fissure in the conventional (C) group. Patient characteristics and perioperative outcomes were compared between groups U and C. Results: The proportions of simple and complex segmentectomies were statistically similar between the groups. The operating time was shorter (group U: 110 [interqurtile range: 90-140] min, group C: 135 [interqurtile range: 105-166] min, p = 0.012) and there was less blood loss (group U: 0 [interqurtile range: 0-0] g, group C: 0 [interqurtile range: 0-50] g, p = 0.003) in group U than in group C. However, there were no significant intergroup differences in other perioperative outcomes. Conclusions: The unidirectional dissection approach in uniportal thoracoscopic pulmonary segmentectomy is safe and feasible and enables a smoother operation.

BACKGROUND: At present, research comparing the short-term postoperative outcomes of anatomical resection in lung cancer under different ports of da Vinci robot-assisted surgery is insufficient. This report aimed to compare the outcomes of three-port and four-port da Vinci robot-assisted thoracoscopic surgery for radical dissection of lung cancer. METHODS: 171 consecutive patients who presented to our hospital from January 2020 to October 2021 with non-small cell lung cancer and treated with da Vinci robot-assisted thoracoscopic surgery for radical resection of lung cancer were retrospectively collected and divided into the three-port group (n = 97) and the four-port group (n = 74). The general clinical data, perioperative data and life quality were individually compared between the two groups. RESULTS: All the 171 patients successfully underwent surgeries. Compared to the four-port group, the three-port group had comparable baseline characteristics in terms of age, sex, tumor location, tumor size, history of chronic disease, pathological type, and pathological staging. The three-port group also had shorter operation time, less intraoperative blood loss, lower chest tube drainage volume, shorter postoperative hospitalization stay durations, but showed no statistically significant difference (P > 0.05). Postoperative 24, 48 and 72 h visual analogue scale pain scores were lower in the three-port group (p < 0.001). No significant difference was observed between the two groups in the hospitalization costs (P = 0.664), number or stations of total lymph node dissected (p > 0.05) and postoperative respiratory complications (P > 0.05). CONCLUSIONS: The three-port robot-assisted thoracoscopic surgery is safe and effective and took better outcomes than the four-port robot-assisted thoracoscopic surgery in non-small cell lung cancer.

BACKGROUND: With the widespread use of low-dose spiral computed tomography (LDCT) and increasing awareness of personal health, the detection rate of pulmonary nodules is steadily rising. OBJECTIVE: To evaluate the success rate and safety of two different models of Hook-Wire needle localization procedures for pulmonary small nodule biopsy. METHODS: Ninety-four cases with a total of 97 pulmonary small nodules undergoing needle localization biopsy were retrospectively analyzed. The cases were divided into two groups: Group A, using breast localization needle steel wire (Bard Healthcare Science Co., Ltd.); Group B, using disposable pulmonary nodule puncture needle (SensCure Biotechnology Co., Ltd.). All patients underwent video-assisted thoracoscopic surgery (VATS) for nodule removal on the same day after localization and biopsy. The puncture localization operation time, success rate, complications such as pulmonary hemorrhage, pneumothorax, hemoptysis, and postoperative comfort were observed and compared. RESULTS: In Group A, the average localization operation time for 97 nodules was 15.47 ± 5.31 minutes, with a success rate of 94.34%. The complication rate was 71.69% (12 cases of pneumothorax, 35 cases of pulmonary hemorrhage, 2 cases of hemoptysis), and 40 cases of post-localization discomfort were reported. In Group B, the average localization operation time was 25.32 ± 7.83 minutes, with a 100% success rate. The complication rate was 29.55% (3 cases of pneumothorax, 15 cases of pulmonary hemorrhage, 0 cases of hemoptysis), and 3 cases reported postoperative discomfort. According to the data analysis in this study, Group B had a lower incidence of puncture-related complications than Group A, along with a higher success rate and significantly greater postoperative comfort. CONCLUSIONS: The disposable pulmonary nodule puncture needle is safer and more effective in pulmonary small nodule localization biopsy, exhibiting increased comfort compared to the breast localization needle. Additionally, the incidence of complications is significantly lower.

BACKGROUND: There is still a debate regarding the most appropriate pleural collector model to ensure a short hospital stay and minimum complications. OBJECTIVES: To study aimed to compare the time of air leak, time to drain removal, and length of hospital stay between a standard water-seal drainage system and a pleural collector system with a unidirectional flutter valve and rigid chamber. DESIGN AND SETTING: A randomized prospective clinical trial was conducted at a high-complexity hospital in São Paulo, Brazil. METHODS: Sixty-three patients who underwent open or video-assisted thoracoscopic lung wedge resection or lobectomy were randomized into two groups, according to the drainage system used: the control group (WS), which used a conventional water-seal pleural collector, and the study group (V), which used a flutter valve device (Sinapi® Model XL1000®). Variables related to the drainage system, time of air leak, time to drain removal, and time spent in hospital were compared between the groups. RESULTS: Most patients (63%) had lung cancer. No differences were observed between the groups in the time of air leak or time spent hospitalized. The time to drain removal was slightly shorter in the V group; however, the difference was not statistically significant. Seven patients presented with surgery-related complications: five and two in the WS and V groups, respectively. CONCLUSIONS: Air leak, time to drain removal, and time spent in the hospital were similar between the groups. The system used in the V group resulted in no adverse events and was safe.

PURPOSE: To investigate the short- and medium-term outcomes following treatment with uniportal video-assisted thoracic surgery lobectomy (uniportal VATS) in elderly patients with non-small cell lung cancer (NSCLC). METHODS: We conducted a retrospective analysis on the clinical and follow-up data of 74 elderly patients with NSCLC who underwent uniportal VATS between January 2015 and January 2020. One-to-one propensity score matching (PSM) was employed to select 71 elderly patients with NSCLC who underwent multiportal video-assisted thoracoscopic lobectomy (multiportal VATS) during the same period. RESULTS: The baseline characteristics of the two patient groups were comparable, with no statistically significant differences in postoperative complications, operation time, conversion to thoracotomy, or lymph node dissection. The amount of intraoperative blood loss and postoperative pain were lower in the uniportal VATS group than in the multiportal VATS group. The 3-year overall survival and disease-free survival of the two groups were similar. CONCLUSIONS: Uniportal VATS achieved similar short- and medium-term outcomes as Multiportal VATS in elderly patients with NSCLC.

Left atrial appendage (LAA) has been found to be associated with the occurrence of thromboembolism in patients with nonvalvular atrial fibrillation (NVAF). Stapling exclusion of LAA during surgical ablation could be an alternative to oral anticoagulation for NVAF patients. However, its safety and efficacy have rarely been examined. Thus, in this study, we aimed to evaluate the safety and efficacy of a powered surgical stapler for LAA resection during ablation for patients with NVAF.Adult patients with NVAF undergoing stapler surgery were included in this study. LAAs of patients were cut off using a powered surgical stapler. Intraoperative transesophageal echocardiogram (TEE) was applied before and after the operation. Each patient received anticoagulant therapy for 2 months after surgery and was regularly followed up by appointment or via telephone call. Patients would undergo physical examinations, echocardiography, and 24-hour dynamic electrocardiogram in a local or in our hospital to determine whether there was a recurrence of atrial fibrillation (AF) or thromboembolism caused by AF.In total, 124 patients were included in this study (male: 88 (71.0%); mean age: 62.3 years). Blood loss was less than 100 mL in all patients with no operative complications or hospital deaths. Moreover, 119 (96.0%) follow-up data were collected, with a mean period of 27.4 months. All patients discontinued oral anticoagulants 2 months after their operation. As per our findings, AF recurred in 23 patients (18.5%), with an average of 9.1 months after surgery. No patients were diagnosed with thromboembolism related to AF.Stapling exclusion of LAA during surgical ablation could safely and completely resect the LAA. The effect of thrombus prevention was deemed satisfactory.

OBJECTIVES: The aim of this study was to evaluate the feasibility, accuracy, and safety of computed tomographic (CT)-guided coil localization before video-assisted thoracoscopic surgery. METHODS: One hundred and eighty-four consecutive patients with 200 pulmonary nodules who underwent CT-guided percutaneous coil localization before thoracoscopic surgery were retrospectively analyzed in this study. Success rate for localization, complication rates, CT findings, and pathological results of the lesions, as well as the data related to surgery were all recorded and analyzed. RESULTS: All 184 patients with 200 lesions completed localization and resection. The success rate of the coil localization on lesion baseline was 99.0% (198/200) and 98.9% (182/184) on patient baseline. The number of wedge resection, segmental resection, and lobectomy were 179 (89.5%), 19 (9.5%), and 2 (1.0%), respectively. The malignancy rates in a lesion-based analysis were 83.5% (91.1% in ground-glass nodules, 91.4% in part-solid nodules, and 37.9% in solid nodules). No serious complications occurred in all localization procedures. CONCLUSION: Preoperative CT-guided percutaneous coil localization is a safe and effective method to facilitate high success rates for both wedge and segmental resection for peripheral pulmonary nodules.

BACKGROUND: At present, an ultrafine chest tube combined with a traditional thick tube were often used after pulmonary uniportal video-assisted thoracoscopic surgery (U-VATS). However, the thick tube was often placed in the incision, which increased the risk of poor wound healing and postoperative pain. The aim of this study is to investigate the feasibility and safety of using two ultrafine chest tubes (10 F pigtail tube) for drainage after pulmonary U-VATS. METHODS: The medical records of patients who underwent pulmonary U-VATS during June 2018 and June 2020 in the department of cardiothoracic surgery of the second affiliated hospital of Soochow university were retrospectively reviewed to compare two different drainage strategies, receiving two 10 F pigtail tubes as chest tube (group A) or one 10 F pigtail tube as lower chest tube combined with one 24 F tube as upper chest tube (group B). RESULTS: 106 patients in group A receiving two 10 F pigtail tubes during June 2019 and June 2020 and 183 patients in group B receiving one 10 F pigtail tube as lower chest tube combined with one 24 F tube as upper chest tube during June 2018 and June 2019 were included. There was no significant difference between two groups in terms of the postoperative thoracic drainage (mL) (1st: 199.54±126.56 vs 203.59±139.32, P=0.84; 2nd: 340.30±205.47 vs 349.74±230.92, P=0.76; 3rd: 435.19±311.51 vs 451.37±317.03, P=0.70; 4th: 492.58±377.33 vs 512.57±382.94, P=0.69; Total: 604.57±547.24 vs 614.64±546.08, P=0.88), drainage time (d) (upper chest tube: 2.54±2.20 vs 3.40±2.07, P=0.21; lower chest tube: (2.24±2.43 vs 3.82±2.12, P=0.10), postoperative hospital stays (d) (6.87±3.17 vs 7.06±3.21, P=0.63), poor wound healing (0 vs 3.28%, P=0.09), replacement of lower chest tube (0.94% vs 2.19%, P=0.66) and the VAS1 (3.00±0.24 vs 2.99±0.15, P=0.63). Notably, there were significant differences between two groups in terms of the VAS2 (2.28±0.63 vs 2.92±0.59, P<0.01) and VAS3 (2.50±1.58 vs 2.79±1.53, P=0.02), as well as the frequency of using additional analgesics (25.47% vs 38.25%, P=0.03) and replacement of the upper chest tube (0 vs 4.37%, P=0.03). CONCLUSIONS: It's feasible and safe to use two 10 F pigtail tubes for drainage after pulmonary U-VATS, which can achieve less postoperative pain and lower frequency of replacement of the upper chest tube on some specific patients.

BACKGROUND: Recent developments in robotic technology have brought significant changes in robotic video-assisted thoracoscopic surgery (r-VATS) worldwide, particularly including the treatment in the thorax for the mediastinal, esophagus, and pulmonary lesions. Currently, there are only a few reports describing the procedural experience and outcomes with r-VATS. The objective of this study is to provide our initial experience using r-VATS at a single center, with specific attention to safety, efficacy, and procedural details. METHODS: We retrospectively reviewed patients who underwent a newly modified r-VATS procedure for various surgical operations at the thoracic department of our hospital, from July 2018 to January 2020. Multiport trocars were placed in the classic triangular arrangement as in conventional VATS (c-VATS) but with modifications based on the type of surgery. The peri- and postoperative outcomes such as duration of surgery, complications, and duration of hospital stay for these patients were reported. RESULTS: Overall, 142 patients underwent r-VATS for lobectomy (66), wedge resection (15), thymectomy (22), mediastinal tumor resection (30), pneumonectomy (4), transthoracic esophagectomy (1), esophageal tumor resection or esophageal diverticulum repair (2), diaphragm plication (1), and mediastinal tumor resection plus thymectomy (1). For the entire cohort, the median operative time was 110 min, and the median length of hospital stay was 5 days. Conversion to open thoracic surgery was reported only in a total of 3 (2.1%) patients of pneumonectomy (1.4%) and mediastinal tumor resection (0.70%). All our patients were managed successfully with no postoperative complications and mortality. CONCLUSION: Our method of r-VATS was found to be safe and effective and may be applied to different surgical operations. Adequate and proper training of thoracic surgeons is immediately needed for the transition from c-VATS to r-VATS. The utility and advantages of triangular trocar configuration for r-VATS require further refinement and research before it can be routinely adopted in clinical practice. TRIAL REGISTRATION: Retrospectively registered.

OBJECTIVE: To test the feasibility of a resorbable self-locking device for sealing of lung tissue in lung lobectomy in experimental dogs and dogs with pulmonary mass, and to study its resorption with CT. STUDY DESIGN: Experimental study and clinical case series. ANIMALS: Five beagles in the experimental group; six canine patients with a pulmonary mass in the clinical group. METHODS: In both groups, an intercostal incision into thorax was performed. A resorbable self-locking device, LigaTie, was applied at the hilum of left cranial lobe in the experimental group and the affected lobe in the clinical group. Each lobe was removed by cutting the tissue just distal to the device. Video-assisted thoracic surgery was used in the experimental group; postoperative diagnostic imaging was repeated monthly until the device was not apparent on CT. RESULTS: Application of LigaTie was feasible for lung lobectomy in all dogs. The device enabled en bloc ligation of the hilum of the affected lobe including the pulmonary arteries and veins and lobular bronchus. No air leakage from the resection stump was observed in any dog. Trace of the device on CT images gradually decreased and was undetectable at 4 months postoperatively in experimental dogs. CONCLUSION: This study suggested that the resorbable self-locking device may be used for sealing of airways in complete lung lobectomy. CLINICAL RELEVANCE: The resorbable self-locking device is suggested to be useful for canine lung lobectomy and may facilitate thoracoscopic lung lobectomy. Further investigations on its clinical application in small animal surgery are warranted.

Herein, realistic and reusable phantoms for simulation of pediatric lung video-assisted thoracoscopic surgery (VATS) were proposed and evaluated. 3D-printed phantoms for VATS were designed based on chest computed tomography (CT) data of a pediatric patient with esophageal atresia and tracheoesophageal fistula. Models reflecting the patient-specific structure were fabricated based on the CT images. Appropriate reusable design, realistic mechanical properties with various material types, and 3D printers (fused deposition modeling (FDM) and PolyJet printers) were used to represent the realistic anatomical structures. As a result, the phantom printed by PolyJet reflected closer mechanical properties than those of the FDM phantom. Accuracies (mean difference ± 95 confidence interval) of phantoms by FDM and PolyJet were 0.53 ± 0.46 and 0.98 ± 0.55 mm, respectively. Phantoms were used by surgeons for VATS training, which is considered more reflective of the clinical situation than the conventional simulation phantom. In conclusion, the patient-specific, realistic, and reusable VATS phantom provides a better understanding the complex anatomical structure of a patient and could be used as an educational phantom for esophageal structure replacement in VATS.

Compensatory sweating (CS) is the most common and disabling complication of endoscopic thoracic sympathectomy and represents an unmet clinical challenge. Our surgical hypothesis is to generate a parallel pathway to the damaged part of the sympathetic nerve, similar to the Kuntz nerve, by reconstructing the 2 healthy intercostal nerves, thus treating CS. Here, we present a novel videothoracoscopic technique involving bilateral intercostal nerve reconstruction in patients with severe CS after endoscopic thoracic sympathectomy.

BACKGROUND: To evaluate the feasibility and safety of microcoil in simultaneous localization for multiple pulmonary nodules before video-assisted thoracic surgery (VATS). METHODS: Twenty-eight consecutive patients (26 two-nodule, 2 three-nodule; 58 nodules in total; Group A) underwent simultaneous CT-guided localization of multiple pulmonary nodules before VATS using microcoil. Successful targeting, localization, and VATS were defined as implantation of microcoil at the target site on CT image which was obtained immediately after the marking procedure, visualization of nodule location, and complete resection of the target nodule with adequate margin, respectively. Meanwhile, the clinical characteristics, localization procedure-related variables of the nodules and procedure-related complications in group A were also assessed and compared with those in a control group (221 single-localization procedures in 221 patients; Group B). RESULTS: Similar rates of successful targeting, localization and VATS were observed in group A and B (96.6% vs. 98.2%; 91.4% vs. 91.0%; 100% vs. 99.1%). Although the rate of overall complications (including localized pneumothorax and intrapulmonary hemorrhage) was a bit higher in group A than that in group B (32.8% vs. 30.8%, p = 0.771), only minor complications were observed in the subjects of the two groups with no need for further treatment. In addition, the duration of simultaneous localization procedures was significantly longer than that of single localization (24 ± 7.5 vs.13 ± 6 min, p < 0.001). CONCLUSIONS: CT-guided simultaneous microcoil localization for multiple pulmonary nodules before VATS was clinically feasible and safe with acceptable increase in the procedure time. Compared with localization for a single pulmonary nodule, simultaneous microcoil localizations for multiple nodules were prone to pneumothorax and hemorrhage. However, no statistically significant differences were observed between the two groups.

Video-assisted thoracoscopic surgery (VATS) anatomical lung resection (ALR) has been gaining popularity in the treatment of lung cancer in line with remarkable advances in both equipment and technique. The development and refinement of its technique have allowed thoracic surgeons to perform a wide variety of challenging and complex procedures in a minimally invasive fashion. Careful and meticulous preparation may shift in the future with the increasing sophistication and capabilities of VATS ALR. Moreover, constant awareness and a structured plan of the procedure are imperative to reducing or preventing complications. Intraoperative major complications during VATS ALR are infrequent, but can have catastrophic consequences. The decision to continue with VATS should take into consideration the surgeon's skill level and ease with the approach and the relative potential benefit against the risk to the patient. We conducted this study to investigate the possible problems during VATS ALR and identify how to solve them based on the previous literature and our institutional data sampling.

OBJECTIVE: To develop and validate a CT-based nomogram to predict the occurrence of loculated pneumothorax due to hook wire placement. METHODS: Patients (n = 177) were divided into pneumothorax (n = 72) and non-pneumothorax (n = 105) groups. Multivariable logistic regression analysis was applied to build a clinical prediction model using significant predictors identified by univariate analysis of imaging features and clinical factors. Receiver operating characteristic (ROC) was applied to evaluate the discrimination of the nomogram, which was calibrated using calibration curve. RESULTS: Based on the results of multivariable regression analysis, transfissure approach [odds ratio (OR): 757.94; 95% confidence interval CI (21.20-27099.30) p < 0.0001], transemphysema [OR: 116.73; 95% CI (12.34-1104.04) p < 0.0001], localization of multiple nodules [OR: 8.04; 95% CI (2.09-30.89) p = 0.002], and depth of nodule [OR: 0.77; 95% CI (0.71-0.85) p < 0.0001] were independent risk factors for pneumothorax and were included in the predictive model (p < 0.05). The area under the ROC curve value for the nomogram was 0.95 [95% CI (0.92-0.98)] and the calibration curve indicated good consistency between risk predicted using the model and actual risk. CONCLUSION: A CT-based nomogram combining imaging features and clinical factors can predict the probability of pneumothorax before localization of ground-glass nodules. The nomogram is a decision-making tool to prevent pneumothorax and determine whether to proceed with further treatment. ADVANCES IN KNOWLEDGE: A nomogram composed of transfissure, transemphysema, multiple nodule localization, and depth of nodule has been developed to predict the probability of pneumothorax before localization of GGNs.

Accumulation of experience and advances in techniques and instruments have enabled surgeons to perform video-assisted thoracic surgery (VATS) safely for sublobar resection, including segmentectomy and wedge resection. A key to successful VATS sublobar resection is to have adequate resection margins and the appropriate use of articulated surgical staplers is essential for this purpose. The SigniaTM stapling system (Covidien Japan, Tokyo) has been used extensively in the fields of thoracic surgery. Its features include high maneuverability with fully powered articulation, rotation, clamping, and firing, which the surgeon can control with one hand. We introduce the "sliding technique" using the SigniaTM system, which allows for adjustment of the resection lines of the pulmonary parenchyma to optimize safe surgical margins with minimal stapler movement, and without repetitively moving the stapler in and out of the pleural cavity, during VATS sublobar resection.

PURPOSE: Single-port video-assisted thoracoscopic (VATS) pulmonary wedge resection was reported in 2004. We started using single-port VATS (SPVATS) pulmonary wedge resection in 2017 and compared results between conventional three-port VATS (VATS group) and SPVATS (SPVATS group). METHODS: We identified 145 consecutive patients with VATS group and SPVATS group. Perioperative characteristics including pain and the number of stapler cartridges used were examined as the surgical outcomes, retrospectively. RESULTS: In all, 66 cases of SPVATS group and 79 cases of VATS group pulmonary wedge resection were compared. The rate of epidural anesthesia (p <0.0001) was significantly higher and operative time (p <0.0001) was significantly longer with VATS group than with SPVATS group. The number of stapler cartridges used, duration of drain insertion, and rate of postoperative complications did not differ significantly between groups. Average numerical rating scale (NRS) score on postoperative day 1 and postoperative day 7 (p <0.0001 each), maximum NRS score on postoperative day 7 (p = 0.0082) and amount of 25 mg tramadol (p = 0.0062) were significantly lower in SPVAS group than in VATS group. CONCLUSION: Our results suggest that SPVATS pulmonary wedge resection offers better pain control and cost-effectiveness than three-port VATS pulmonary wedge resection. These findings should contribute to the body of evidence for SPVATS.

BACKGROUND: We previously reported useful methods that can be implemented to identify intersegmental boundary lines (IBLs) by using an intravenous indocyanine green (ICG) fluorescence imaging system (ICG-FS) during a thoracoscopic anatomical segmentectomy (TAS). The aim of this study was to evaluate the recently released third-generation ICG-FS that features an emphasizing xenon-light source for IBL identification. METHODS: We prospectively studied cases involving 106 consecutive patients who underwent TAS. Intraoperatively, we used the third-generation ICG-FS, the conventional ICG methods (CIM) emphasizing xenon-light (CIM-X), and the spectra-A method (SAM) emphasizing xenon-light (SAM-X), for IBL identification. Furthermore, 16 of the 106 patients (15%) could be simultaneously evaluated using old-generation ICG-FSs, CIM, and SAM. All images were completely quantified for illuminance and for three colors, red, green, and blue. RESULTS: IBLs were successfully identified in all the patients (100%) with no adverse events. The SAM-X significantly increased the illuminance, especially in the resecting segments, compared to the CIM (39.0 versus 22.2, P < 0.01) and SAM (39.0 versus 29.3, P < 0.01), with enhanced red color compared to the CIM (33.1 versus 21.9, P < 0.01) and SAM (33.1 versus 14.0, P < 0.01). Furthermore, the SAM-X significantly increased the illuminance contrast compared to the CIM-X (34.1 versus 15.3, P < 0.01). CONCLUSIONS: The present study suggests that the SAM-X potentially provided images with the highest visibility and colorfulness compared to the older generation ICG-FSs or CIM-X. Secure IBL identification can be more easily and safely performed using the SAM-X.

The resection of nodules by thoracoscopic surgery is difficult because the nodules may be hard to identify. Preoperative localization of pulmonary nodules is widely used in the clinic. In this study, we retrospectively compared CT-guided hook wire localization and electromagnetic navigation bronchoscopy (ENB) localization of small pulmonary nodules before resection. Patients who underwent localization with CT-guided hook wire or ENB followed by video-assisted thoracoscopic surgery (VATS) at Qilu Hospital of Shandong University between January 2016 and December 2019 were retrospectively included. Clinical parameters, complication and failure rate, and localization time were compared between two groups. A total of 157 patients underwent the localization procedure successfully. Pulmonary nodules were localized by CT-guided hook wire in 105 patients and by ENB in 52 patients. The nodule size in ENB group was smaller than that in CT-guided localization group (P < 0.001). Both CT-guided localization and ENB localization were well tolerated in all patients, while ENB localization leaded to less complications (P = 0.0058). In CT-guided localization group, 6 patients failed to be located while none failed in ENB group (P = 0.079). The procedure time was 15.15 ± 3.70 min for CT-guided localization and 21.29 ± 4.00 min for ENB localization (P < 0.001). CT-guided localization is simple and feasible for uncertain pulmonary nodules before surgery. ENB localization could identify small lung nodules with high accuracy and achieve lower incidence of complications.
