Accurate and non-invasive localization of multi-focal ground-glass opacities via electromagnetic navigation bronchoscopy assisting video-assisted thoracoscopic surgery: a single-center study.

Accurate localization of multi-focal ground-glass opacities (GGOs) is crucial for successful video-assisted thoracoscopic surgery (VATS). Electromagnetic navigation bronchoscopy (ENB) provides a minimally invasive and dependable approach for precise localization. This study assessed the accuracy and safety of ENB-guided localization in cases involving multi-focal GGOs. This retrospective study presents a single-center investigation into ENB-guided localization, utilizing methylene blue, for multi-focal GGOs assisting VATS. Clinical, surgical, and pathological data were collected from patients who underwent ENB-guided localization between 23 December 2019 and 31 August 2022. The study examined 57 patients with multi-focal GGOs who underwent ENB-guided localization and VATS. A total of 150 GGOs were treated, with ENB-guided localization taking a median time of 65min. Following localization, all patients proceeded to VATS, with a median duration of 170min. The median lesion size measured 7.8mm, with a 5-mm distance between GGO and pleura or fissure. When the distance between GGO and pleura/fissure exceeded 1cm, an additional location point was introduced below the pleura or fissure based on GGO location. No complications related to localization were observed. The overall malignancy rate stood at 66%. Location precision was confirmed by measuring the marker-to-GGO lesion distance, resulting in a 94% (141/150) accuracy rate for GGO localization. ENB-guided methylene blue injection is a safe and precise method to treat multi-focal GGOs, potentially minimizing operation time and simplifying lesion detection.

Advantages and feasibility of intercostal nerve block in uniportal video-assisted thoracoscopic surgery (VATS)

ABSTRACT Objectives Uniportal video-assisted thoracic surgery (VATS) has been successfully used worldwide as a minimally invasive method of thoracoscopic surgery. Although pain was significantly reduced after VATS, acute postoperative pain was still significant. This study aimed to assess the advantages and feasibility of intercostal nerve block in uniportal VATS. Methods We conducted a retrospective analysis of perioperative data from 280 consecutive patients who underwent uniportal VATS at our institution between May 2021 and February 2022. The patients were assigned to either Group A (142 patients with 3 intercostal nerves blocked) or Group B (138 patients with 5 intercostal nerves blocked). We analyzed the perioperative data of both groups and utilized repeated measures ANOVA to determine the difference in postoperative pain between the two groups across time. Results A total of 280 patients underwent successful uniportal VATS during the study period. There were no significant differences between Group A and Group B in terms of age, gender, pulmonary function, arterial blood gas analysis, laterality, incision location, nodule size, nodule location, operative time, blood loss, drainage time, length of hospital stays, tumor stage, or postoperative complications. Furthermore, no surgical or 30-day postoperative mortalities occurred. Using repeated measures ANOVA, we found that the intercostal nerve block had significant effects on the group, time, and interaction terms group × time (P < 0.05). Conclusion Intercostal nerve block is safe and effective, and is associated with simple, accurate, and high patient satisfaction as opposed to other postoperative analgesics in uniportal VATS. Blocking five intercostal nerves may be more beneficial for effective postoperative pain management. Nevertheless, further confirmation through prospective randomized controlled trials is required.

Factors Associated With Successful Video-Assisted Thoracoscopic Surgery for Traumatic Hemothorax in Children: A Cross-Sectional Study

IntroductionDue to the rarity of traumatic hemothorax in children, no studies have evaluated factors associated with successful video-assisted thoracoscopic surgery (VATS) as definitive management. MethodsWe conducted an exploratory cross-sectional analysis of pediatric patients in the Trauma Quality Programs database from 2008 to 2017 with traumatic hemothorax managed with primary VATS. Those with early resuscitative thoracotomy for cardiac arrest were excluded. We stratified patients by blunt or penetrating mechanism and estimated absolute differences (ADs) and 95% confidence intervals (CIs) to identify factors associated with successful VATS without conversion to thoracotomy or reoperation. ResultsA total of 293 patients were eligible. Among 184 penetrating injuries, 150 (82%) underwent successful VATS, 6 (3%) required reoperation, and 28 (15%) converted to thoracotomy. Diaphragmatic injuries (AD = −28, 95% CI = −46 to −10) and rib fractures (AD = 12, 95% CI = 1 to 23) had the strongest negative and positive associations (respectively) with successful VATS. There were 109 blunt injuries: 86 (79%) underwent successful VATS, 6 (6%) required reoperation, and 17 (16%) converted to thoracotomy. Moderate or severe head injury (AD = −15, 95% CI = −32 to 2), injury severity score >15 (AD = −19, 95% CI = −33 to −5), and the presence of diaphragmatic injury (AD = −38, 95% CI = −71 to −4) had the strongest negative associations with successful VATS. ConclusionsSome children with traumatic hemothorax can be successfully managed with VATS. For penetrating mechanism, diaphragmatic injuries were associated with less success, while rib fractures were associated with more success. For blunt mechanism, diaphragmatic injuries, injury severity score >15, or moderate or severe head injury were associated with less success.

Intraoperative conversion from video-assisted thoracoscopic lobectomy to thoracotomy for non-small-cell lung cancer: Does it have an impact on long-term survival?

SummaryA best evidence topic in thoracic surgery was written according to a structured protocol. The question addressed was whether intraoperative conversions to thoracotomy have an impact on long-term survival for patients with non-small-cell lung cancer who underwent video-assisted thoracoscopic lobectomy initially. A total of 461 papers were found using the reported search, of which 6 retrospective cohort studies represented the best evidence to answer the clinical question. The authors, date of publication, journal, country of the authors, patient group, study type, relevant outcomes and results of these papers were tabulated. Five cohort studies clarified that conversion did not compromise long-term survival, whereas 1 cohort study reported worse long-term outcomes after conversion to thoracotomy. However, the limited samples, different characteristics between groups and selection bias due to inherent design made it difficult to make a conclusion. Based on the current evidence, we concluded that intraoperative conversion from video-assisted thoracoscopic surgery (VATS) to thoracotomy for non-small-cell lung cancer might not impact long-term survival compared to a successful VATS lobectomy. In-hospital mortality might not be prejudiced, whereas longer hospitalizations were observed. However, whether conversion would adversely affect postoperative complication rates remained unclear because of the conflicting results. Moreover, 3 studies reported no statistical differences in short- and long-term survival between emergency and non-emergency conversions. Therefore, we suggest that thoracic surgeons should not hesitate to convert VATS into thoracotomy in the case of blood vessel injury or difficult hilum.

Subxiphoid Video-Assisted Thoracoscopic Surgery for Lung Resection Under Spontaneous Ventilation: Case Report

This case report describes two patients that underwent successful video-assisted thoracoscopic surgery (VATS) lung resections under spontaneous ventilation using the uniportal subxiphoid approach. The authors performed lung wedge resection in both patients under local anesthesia without using of a Foley catheter, arterial line, or intercostal chest drain. Only intravenous drugs and an oxygen mask with reservoir bag were used. The postsurgical course for both patients was uneventful. Both were discharged on postoperative day 2 and were doing well at 1- and 3-month follow-ups. Keywords: Subxiphoid approach; Pulmonary resection; Lung cancer

Factors Associated with Successful Video-Assisted Thoracoscopic Surgery and Thoracotomy in the Management of Traumatic Hemothorax

Few studies have identified factors associated with successful VATS or thoracotomy as the initial operative strategy among patients with traumatic hemothorax. We performed an exploratory analysis using the 2008 to 2017 TQP database. We identified all patients aged 18 to 89 years with traumatic hemothorax who were treated with tube thoracostomy alone in the first 24-hours of admission, followed by VATS or thoracotomy. Logistic regression was used to identify factors associated with successful VATS (no conversion or reoperation) or thoracotomy (no reoperation) as the initial operative strategy. Among 2052 patients managed with initial VATS after chest tube drainage, 1710 (83%) were successful, while 263 (13%) were converted to thoracotomy and 79 (4%) required reoperation. On multivariable analysis, poor GCS (OR=0.96 [95% CI=0.94-0.99]), major injury (OR=0.69 [95% CI=0.53-0.90]), and diaphragmatic injury (OR=0.42 [95% CI=0.30-0.60]) were associated with lower odds of successful VATS, while rib fractures (OR=1.29 [95% CI=1.01-1.66]) were associated with higher odds of success of the initial operative plan. Among 3486 patients initially managed with thoracotomy after drainage with tube thoracostomy, 3118 (89.4%) were successful, while 11% (n=368) required reoperation. Multivariable analysis revealed that major injury (OR=0.68 [95% CI=0.50-0.92]), blunt mechanism (OR=0.63 [95% CI=0.50-0.78]), and diaphragmatic injury (OR=0.67, 95% CI=0.53-0.84]) were associated with lower odds of successful thoracotomy as the initial operative plan. More severe injuries and diaphragmatic injuries have lower odds of successful of VATS or thoracotomy as the initial operative management strategy among patients with traumatic hemothorax. Rib fractures may be associated with higher odds of success of VATS as the initial management strategy.

Management of Complications During Video-Assisted Thoracic Surgery Lung Resection and Lymph Node Dissection.

Intraoperative events can occur during video-assisted thoracoscopic surgery (VATS) lobectomy due to unfavorable surgical anatomy, such as dense adhesions or calcifications around the pulmonary arteries. Troubleshooting intraoperative complications is essential for performing safe and successful VATS pulmonary resection and lymph node dissection. If continuous bleeding occurs or VATS does not proceed despite all measures, conversion to open thoracotomy should not be delayed.

Anesthetic Challenges During Video-Assisted Thoracoscopic Surgeries for Pediatric Empyema Thoracis: A Case Series

Video-assisted thoracoscopic surgery (VATS) is a less invasive approach for thoracoscopic surgery providing better visualization through minimal access. In addition, it offers less postoperative pain, fewer operative complications, and shortened hospital stay. These advantages make VATS ideal for the pediatric age group. Various societies recommend the use of VATS for Stage 2 pulmonary empyema and also in some cases of early Stage 3 where the plane of cleavage exists between the pleura and the exudate. A well-executed one-lung ventilation (OLV) is necessary for a successful VATS; however, performance of OLV and postoperative pain management in children poses a challenging task for an anesthesiologist.

Computed Tomography-Guided Trans-scapular Coil Localization for Pulmonary Nodules.

The aim of the study is to evaluate the feasibility, safety, and effectiveness of preoperative computed tomography (CT)-guided trans-scapular coil localization (TSCL) of scapula-blocked pulmonary nodules (PNs). Between November 2015 and May 2020, 11 patients underwent preoperative CT-guided TSCL procedures owing to PN occlusion by scapula. A 100% technical success rate was achieved for CT-guided TSCL, with one coil being used for each PN. One patient (9.1%) developed pneumothorax. Successful video-assisted thoracoscopic surgery (VATS)-guided wedge resection of these scapula-blocked PNs was conducted in all patients. CT-guided TSCL can be simply and safely used to facilitate successful VATS-guided wedge resection of scapula-blocked PNs.

Successful video-assisted thoracoscopic surgery in prone position in patients with esophageal cancer and aberrant right subclavian artery: report of three cases

BackgroundAn aberrant right subclavian artery (ARSA) with an associated nonrecurrent right inferior laryngeal nerve (NRILN) is a relatively rare anomaly that occurs at a frequency of 0.3 to 2.0% of the general population. NRILN has been mainly documented in the head and neck region; it has been rarely described in patients with esophageal cancer, especially those undergoing thoracoscopic surgery. Video-assisted thoracoscopic surgery for esophageal cancer (VATS-E) is becoming more widespread as a reliable minimally invasive surgical procedure associated with reduced perioperative complications.Case presentationHerein, we report three cases of esophageal cancer with ARSA and NRILN which underwent successful VATS-E. Case 1, a 53-year-old male who had early stage esophageal cancer was performed VATS-E. Upper gastrointestinal (GI) series showed “Bayonet sign” (T1aN0M0, pStageIA in UICC). Case 2, a 75-year-old male who had advanced esophageal cancer was performed neoadjuvant chemotherapy and following VATS-E. This case had right thoracic duct and “Bayonet sign” on upper GI series (T1bN2M0, pStage IIIA in UICC). Case3, a 72-year-old male who had advanced esophageal cancer was performed neoadjuvant chemotherapy and following VATS-E (T3N2M0, pStageIIIB in UICC). All of these three cases were performed VATS-E and discharged without any complication.ConclusionVATS-E in the prone position is a feasible procedure that can reduce the risk of complications with an enlarged and clear view, and knowledge of this type of anomaly is very important for surgeons who perform esophagectomy.

The feasibility and advantage of uniportal video-assisted thoracoscopic surgery (VATS) in pulmonary lobectomy

BackgroundOngoing improvements in technique and instruments for video-assisted thoracoscopic surgery (VATS) have made minimally-invasive uniportal VATS lobectomy a reality. However, the outcomes of the procedure are still under investigation, and at present, uniportal VATS lobectomy is performed infrequently at most hospitals. We have therefore reviewed our outcomes with this procedure in an attempt to validate its safety, efficacy, and feasibility.MethodsWe retrospectively analyzed and compared perioperative data for patients who underwent uniportal, two-port, and traditional three-port VATS lobectomy between January 2015 and December 2015 at our hospital.ResultsAmong 257 patients who had successful VATS lobectomy during the study period, 73 underwent uniportal VATS, 86 underwent two-port VATS, and 98 underwent traditional three-port VATS. There were no surgical or 30-day postoperative mortalities, and no significant differences in operative times, blood loss, number of lymph nodes retrieved and nodal stations explored, drainage times, length of hospital stay, or postoperative complications among the three groups. The visual analogue scale (VAS) pain scores were significantly lower in the uniportal VATS group after surgery (P < 0.05).ConclusionsUniportal VATS lobectomy is a safe and feasible surgical procedure that is associated with decreased surgical trauma and less postoperative pain compared to traditional VATS. Further long term follow-up analyses in large numbers of patients are ongoing.

Comparative Effectiveness and Safety of Preoperative Lung Localization for Pulmonary Nodules: A Systematic Review and Meta-analysis

An optimal method of preoperative localization for pulmonary nodules has yet to be established. This systematic review and meta-analysis aimed to compare the success andcomplication rates associated with three pulmonary nodule localization methods for video-assisted thoracoscopic surgery (VATS): hook-wire localization, microcoil localization, and lipiodol localization. We searched the PubMed, MEDLINE, and EMBASE databases for prospective or retrospective English language studies of VATS localization in adult patients. A noncomparative, random effects model-based meta-analysis was performed to obtain pooled success and complication rates for the three localization methods. A total of 46 clinical studies were enrolled, including 30, 9, and 7 studies of hook-wire, microcoil, and lipiodol localization, respectively. The successful targeting rates for hook-wire, microcoil, and lipiodol localization were 0.98 (95%CI, 0.97-0.99), 0.98 (95%CI, 0.96-0.99), and 0.99 (95%CI, 0.98-1.00), respectively, with corresponding successful operative field targeting rates of 0.94 (95%CI, 0.91-0.96), 0.97 (95%CI, 0.95-0.98), and 0.99 (95%CI, 0.98-1.00), respectively. In addition, the successful VATS rates with hook-wire, microcoil, and lipiodol localization were 0.96 (95%CI, 0.94-0.97), 0.97 (95%CI, 0.94-0.99), and 0.99 (95%CI, 0.98-1.00), respectively. Regarding complications, hook-wire, microcoil, and lipiodol localization were associated with pneumothorax rates of 0.35 (95%CI, 0.28-0.43), 0.16 (95%CI, 0.07-0.34), and 0.31 (95%CI, 0.20-0.46), respectively and hemorrhage rates of 0.16 (95%CI, 0.11-0.23), 0.06 (95%CI, 0.03-0.11), and 0.12 (95%CI, 0.05-0.23), respectively. All three localization methods yielded similarly highly successful targeting rates. However, hook-wire localization had a relatively lower successful operative field targeting rate because of dislodgement or migration. Lipiodol localization had the highest overall success rate, and microcoil localization yielded the lowest complication rates.

Handheld single photon emission computed tomography (handheld SPECT) navigated video-assisted thoracoscopic surgery of computer tomography-guided radioactively marked pulmonary lesions

Radioactive marking can be a valuable extension to minimally invasive surgery. The technique has been clinically applied in procedures involving sentinel lymph nodes, parathyroidectomy as well as interventions in thoracic surgery. Improvements in equipment and techniques allow one to improve the limits. Pulmonary nodules are frequently surgically removed for diagnostic or therapeutic reasons; here video-assisted thoracoscopic surgery (VATS) is the preferred technique. VATS might be impossible with nodules that are small or located deep in the lung. In this study, we examined the clinical application and safety of employing the newly developed handheld single photon emission tomography (handheld SPECT) device in combination with CT-guided radioactive marking of pulmonary nodules. In this pilot study, 10 subjects requiring surgical resection of a pulmonary nodule were included. The technique involved CT-guided marking of the target nodule with a 20-G needle, with subsequent injection of 25-30 MBq (effective: 7-14 MBq) Tc-99m MAA (Macro Albumin Aggregate). Quality control was made with conventional SPECT-CT to confirm the correct localization and exclude possible complications related to the puncture procedure. VATS was subsequently carried out using the handheld SPECT to localize the radioactivity intraoperatively and therefore the target nodule. A 3D virtual image was superimposed on the intraoperative visual image for surgical guidance. In 9 of the 10 subjects, the radioactive application was successfully placed directly in or in the immediate vicinity of the target nodule. The average size of the involved nodules was 9 mm (range 4-15). All successfully marked nodules were subsequently completely excised (R0) using VATS. The procedure was well tolerated. An asymptomatic clinically insignificant pneumothorax occurred in 5 subjects. Two subjects were found to have non-significant discrete haemorrhage in the infiltration canal of the needle. In a single subject, the radioactive marking was unsuccessful because the radioactivity spread into the pleural space. In our series of 10 patients, it was demonstrated that using handheld SPECT in conjunction with VATS to remove radioactively marked pulmonary nodules is feasible. The combination of proven surgical techniques with a novel localization device (handheld SPECT) allowed successful VATS excision of pulmonary nodules which, due to their localization and small size, would typically have required thoracotomy.

The Role of Video-Assisted Thoracoscopic Therapeutic Resection for Medically Failed Pulmonary Tuberculosis.

There are few reports regarding video-assisted thoracoscopic therapeutic resection for medically failed pulmonary tuberculosis (TB). We reviewed our surgical results of video-assisted thoracoscopic surgery (VATS) therapeutic resection for pulmonary TB with medical failure, and its correlation with image characteristics on chest computed tomography (CT) scan.Between January 2007 and December 2012, among the 203 patients who had surgery for TB, the medical records of 89 patients undergoing therapeutic resection for medically failed pulmonary TB were reviewed. Clinical information and the image characteristics of CT scan were investigated and analyzed.Forty-six of the 89 patients undergoing successful VATS therapeutic resection had significantly lower grading in pleural thickening (P < 0.001), peribronchial lymph node calcification (P < 0.001), tuberculoma (P = 0.015), cavity (P = 0.006), and aspergilloma (P = 0.038); they had less operative blood loss (171.0 ± 218.7 vs 542.8 ± 622.8 mL; P < 0.001) and shorter hospital stay (5.2 ± 2.2 vs 15.6 ± 15.6 days; P < 0.001). They also had a lower percentage of anatomic resection (73.9% vs 93.0%; P = 0.016), a higher percentage of sublobar resection (56.5% vs 32.6%; P = 0.023), and a lower disease relapse rate (4.3% vs 23.3%; P = 0.009). Eighteen of the 38 patients with multi-drug resistant pulmonary tuberculosis (MDRTB) who successfully underwent VATS had significantly lower grading in pleural thickening (P = 0.001), peribronchial lymph node calcification (P = 0.019), and cavity (P = 0.017). They were preoperatively medicated for a shorter period of time (221.6 ± 90.8 vs 596.1 ± 432.5 days; P = 0.001), and had more sublobar resection (44.4% vs 10%), less blood loss (165.3 ± 148.3 vs 468.0 ± 439.9 mL; P = 0.009), and shorter hospital stay (5.4 ± 2.6 vs 11.8 ± 6.9 days; P = 0.001).Without multiple cavities, peribronchial lymph node calcification, and extensive pleural thickening, VATS therapeutic resection could be safely performed in selected patients with medically failed pulmonary TB as an effective adjunct with satisfactory results.

How to deal with benign hilar or interlobar lymphadenopathy during video-assisted thoracoscopic surgery lobectomy.

Video-assisted thoracoscopic surgery (VATS) surgery has changed the way lobectomy procedure was performed over the past few decades. However, some difficulties impede the accomplishment of VATS lobectomy, which of them, benign lymphadenopathy may pose a threat to safety of surgery. We reported a case with enlarged hilar and interlobar lymph nodes. The video showed the instrumentation and techniques that we had adopted to deal with the complicated dilemma during the operation. Critical experience was also suggested in some hypothetical scenarios. AS techniques were further refined, successful VATS segmentectomy or lobectomy with challenging hilar or interlobar lymphadenopathy could be performed without uncontrolled bleeding or unexpected conversion. A VATS approach is acceptable in the management of benign hilar or interlobar lymphadenopathy. However, facile technique is necessary to deal with intraoperative dilemma. To those who are not sure about the practicability of the VATS procedure, planned conversion is still an effective method to ensure safety of the operation.

Urgent awake thoracoscopic treatment of retained haemothorax associated with respiratory failure.

A number of video-assisted thoracoscopic surgery (VATS) procedures are being increasingly performed by awake anesthesia in an attempt of minimizing the surgical- and anesthesia-related traumas. However, so far the usefulness of awake VATS for urgent management of retained haemothorax has been scarcely investigated. Herein we present two patients with retained haemothorax following previous thoracentesis and blunt chest trauma, respectively, who developed acute respiratory failure and underwent successful urgent awake VATS management under local anesthesia through a single trocar access.

Nursing for the complete VATS lobectomy performed with non-tracheal intubation.

Video-assisted thoracoscopic surgery (VATS) has without doubt been the most important advance in thoracic surgery. The general anesthesia before the tracheal intubation for VATS was often accompanied with tracheal mucosa and lung injuries, which were typically manifested as painful throat, nausea, vomiting, and other symptoms. However, the non-intubated anesthesia VATS can avoid these shortcomings due to its shorter anesthesia time, simpler steps, and quicker post-operative recovery. A total of 63 patients underwent VATS lobectomy under non-intubated anesthesia from July 2012 to July 2013. Good teamwork, proper pre-operative visit, and comfortable intra-operative position had ensured the success of these operations. In conclusion, adequate pre-operative preparation, careful nursing, and close cooperation can achieve a successful non-intubated anesthesia VATS.

Adopting a standardized anterior approach significantly increases video-assisted thoracoscopic surgery lobectomy rates

Video-assisted thoracoscopic surgery (VATS) lobectomy is associated with improved short-term outcomes compared with thoracotomy. Definition of the hilar structures is crucial to safe VATS lobectomy. Several VATS approaches have been described. We report the effect of three surgeons in our institution undertaking standardized anterior approach (SAA) training on the proportion of isolated lobectomies subsequently completed by VATS. Predictors of successful VATS lobectomy were analysed. Three consultant surgeons undertook SAA training at two different time points. Two were performing VATS lobectomy prior to SAA training. Training involved a 2-day visit to an established SAA unit. Lobectomies performed by these surgeons between April 2011 and December 2012 (20 months), before and after training, were recorded prospectively. Bilobectomies, sleeve resections, pneumonectomies and chest wall resections were excluded. VATS lobectomy proportions before and after training were compared. Independent predictors of completion by VATS rather than thoracotomy were identified by multivariable logistic regression. One hundred and sixty-three isolated lobectomies were performed, 97 of these by VATS (59.5%). The mean age was 68.8 (± 10.5) years. Pathology was lung cancer in 137 (84.0%), other primary malignancy in 10 (6.1%), pulmonary metastases in 8 (4.9%) and benign in 8 (4.9%). The VATS lobectomy rate rose from 22.2% before SAA training to 77.3% after, P < 0.001. The effect was significant for both existing and adopting VATS lobectomy surgeons, P = 0.002 to <0.001. The median hospital stay was 4 days after VATS and 5 after thoracotomy, P < 0.001. There were 5 in-hospital deaths after thoracotomy and none after VATS lobectomy, unadjusted P = 0.01. In the final logistic regression model, SAA training was the strongest predictor of successful VATS lobectomy (odds ratio 15.16; 95% confidence interval 6.39, 35.96). Formal training and adoption of the SAA approach were associated with a more than 3-fold increase in our VATS lobectomy rate. The effect was immediate and sustained. This may reflect easier identification of the major structures from the anterior view. In addition, standardization of surgical techniques and perioperative protocols may facilitate efficient team working. VATS lobectomy was associated with a shorter median hospital stay. Units seeking to increase their VATS lobectomy rate should consider group adoption of the SAA approach.

Preoperative Predictors of Successful Surgical Treatment in the Management of Parapneumonic Empyema

Video-assisted thoracoscopic surgery (VATS) and thoracotomy are the main surgical options for treating parapneumonic empyema. The choice of either operation depends on many preoperative features, including the patient's condition, clinical and radiologic findings, and pleural fluid characteristics. The identification of the combination of those preoperative findings that will allow surgeons to select the appropriate approach for a successful operation (VATS or thoracotomy) could be of great interest in clinical settings. We retrospectively reviewed a series of 97 patients who had undergone successful VATS or thoracotomy for parapneumonic empyema; in all cases, the operation had begun through VATS and was changed to a thoracotomy if a complete decortication was needed. Preoperative clinical, radiologic, and laboratory features were compared between the two groups to search for differences that might serve as predictive factors for either operation. Perioperative findings were also analyzed. The operation was accomplished by VATS in 40 patients (41%), and conversion to thoracotomy was necessary in 57 (59%). Significant predictive factors for conversion were a prolonged delay from diagnosis to operation, the presence of fever and of pleural thickness on computed tomography (CT) images. The 25 patients who presented with these three features were cured by thoracotomy. The operative time and postoperative complication rate were significantly higher for the thoracotomy patients. Some preoperative features can help the surgeon to better select patients for the appropriate operation. Delayed operation, fever, and pleural thickness can be used to predict the likelihood of conversion to thoracotomy.

Presurgical Planning Using a Three-Dimensional Pulmonary Model of the Actual Anatomy of Patient with Primary Lung Cancer

Video-assisted thoracoscopic surgery (VATS) for both lobectomy and segmentectomy has been used widely for early stage nonsmall cell lung cancer (NSCLC). The objective of this study was to investigate the clinical feasibility of surgical planning using patient's actual three-dimensional (3D) pulmonary model for the thoracoscopic surgical treatment of early stage NSCLC. We examined 57 patients with stage IA NSCLC ≤ 2 cm in diameter. Based on patient's actual 3D pulmonary model created by using a homemade software program called CTTRY (Tokyo Women's Medical University, Tokyo, Japan), both the location of and extent of tumor invasion were assessed, and a suitable type of VATS lung resection for an individual was selected. By the 3D models, tumors in 47 patients were localized within one segment, and other tumors (10 patients, 18%) were involved in multiple segments. VATS lung resections consisted of a single segmentectomy were performed in 25 patients; upper division resections, 9; lingulectomy, 5; extended segmentectomy, 7; single subsegmentectomy, 6; and multiple subsegmentectomy, 5. All 57 patients underwent successful VATS lung resection without massive bleeding. Presurgical planning based on patient's actual 3D pulmonary model is useful for patients with stage IA NSCLC ≤ 2 cm in diameter and for selecting an appropriate VATS lung resection for an individual.
