RESUMEN
BACKGROUND: More than 50% of esophageal cancer patients are diagnosed with advanced diseases and commonly experience dysphagia, some of whom even have tracheoesophageal fistula. Self-expandable metal stent (SEMS) is one of the recommended palliative methods, although complications such as chest pain and stent migration are not uncommon. The goal of this study was to examine the predictors of stent migration. METHODS: We conducted a retrospective cohort study to include patients with esophageal cancer and dysphagia/tracheoesophageal fistula. Clinicopathological information, stent characteristics and patient outcomes were collected for analysis, while side-effects of SEMS were recorded, potential predictors were examined, and patients' nutritional outcomes were compared in the migration and non-migration groups. RESULTS: A total of 54 patients with esophageal cancer who received fully covered SEMS between 2013 and 2022 were included. We found tumor across the esophagogastric junction (adjusted odds ratio (OR) = 32.64, P = 0.01) and the female sex (adjusted OR = 12.5, P = 0.02) were significant predictors for stent migration. There was a decreasing tendency in body mass index/body weight in migration and non-migration groups, but the former had a steeper downslope. CONCLUSION: Fully covered SEMS is a safe and effective strategy to palliate dysphagia or fistula. Tumor across esophagogastric junction and the female sex were higher risk predictors of stent migration. A careful patient selection would optimize the effects of SEMS placement, especially in those with short-expected lifespan.
RESUMEN
BACKGROUND: Patients with locally advanced esophageal squamous cell carcinoma (ESCC) following neoadjuvant chemoradiotherapy (nCRT) may not always receive resection despite the possible achievement of a pathologic complete response (pCR) being associated with superior survival benefit. We aimed to compare outcomes among ESCC patients with or without pCR and those refusing surgery. METHODS: In total, 111 medically operable, non-cervical ESCC patients after the same protocol of nCRT (platinum/5-fluorouracil plus radiation 50Gy) were prospectively enrolled between 2011 and 2021. Eighty-three of them underwent esophagectomy comprising pCR (n = 32) and non-pCR (n = 51), while 28 operable patients declined surgery (refusal-of-surgery group). Predictors and survival data were analyzed. RESULTS: In terms of esophagectomy, 38.5% (32/83) patients achieved pCR. The pCR group exhibited better pretreatment performance status than the non-pCR group (adjusted odds ratio: 0.11, 95% confidence interval: 0.03-0.58; p = 0.01). Among pCR, non-pCR, and refusal-of-surgery groups, the 5-year overall survival (OS) rates were 56%, 29% and 50% (p = 0.08) and progression-free survival (PFS) rates were 52%, 28% and 36% (p = 0.07) respectively. The pCR group had significantly better OS and PFS than the non-PCR group (adjusted hazard ratio: 2.33 and 1.93, p = 0.02 and 0.049 respectively) but not the refusal-of-surgery group. CONCLUSION: Better pretreatment performance status is associated with higher chance of pCR. Consistent with previous studies, we found attainment of pCR confers the best OS and PFS. Suboptimal OS in the refusal-of-surgery group reflects some of them would have residual disease in addition to complete remission. Further studies are needed to identify prognostic factors of pCR to select candidates who could validly decline esophagectomy.

BACKGROUND: Although uncommon, available evidence suggests that pneumorrhachis (PR) with spontaneous pneumomediastinum (SPM) in adulthood is usually benign and self-limiting. This study aimed to review our experience and identify the risk factors of PR in pediatric patients with SPM. METHODS: Between September 2007 and September 2017, SPM in patients aged ≤18 years was retrospectively reviewed and clinical features and outcomes between SPM patients with and without PR were analyzed. RESULTS: In total, thirty consecutive occurrences of SPM in 29 patients were finally identified and classified into SPM (n = 24) and SPM plus PR (n = 6) groups. No significant differences in received interventional exams, prophylactic antibiotic administration or restriction of oral intake between the two groups were found. Both groups were treated with hospitalization predominantly; but the SPM plus PR group tended to have longer length of hospital stay (median 5.5 vs. 3 days, p = 0.08). PR was observed more frequently in patients with abnormal serum C-reactive protein (CRP) levels (>5 mg/L), identified predisposing factors, and those with more severe grade of SPM (p = 0.005, 0.001 and < 0.001, respectively). On multivariable regression analysis, the SPM plus PR group exhibited more predisposing factors than did the SPM group (coefficient: 0.514, standard error: 0.136, p < 0.001). All patients were successfully treated without morbidity and mortality. CONCLUSION: Although patients with pneumorrhachis retained a higher CRP level, more identified predisposing factors and prolonged inpatient care, conservative management without an extensive work-up would be an appropriate and favorable strategy in pediatrics with concurrent SPM and PR.

BACKGROUND: Simultaneous bilateral thoracoscopic lung resection (SBTLR) has been shown to be a feasible and efficacious approach for a wide range of pulmonary conditions. Our aim was to evaluate the impact of different procedures on surgical outcomes in patients receiving SBTLR. METHODS: Between 2012 and 2021, 207 patients with bilateral lung neoplasms who underwent SBTLR were retrospectively reviewed. Fifty-one patients received ipsilateral plus contralateral lobectomy or sublobectomy (lobar group), whilst 156 patients received bilateral sublobectomy (sublobar group). Propensity scores were calculated and matched. Perioperative and clinicopathologic outcomes were compared. RESULTS: The lobar group had a greater mean age (64.5 vs. 60.0 years, p = 0.008), longer operative time (254 vs. 205 min, p < 0.001), and more blood loss (74 vs. 46 ml, p < 0.001). The sublobar group had fewer complications (6.4 vs. 19.6%, p = 0.006), shorter hospital stay (4.8 vs. 7.4 days, p < 0.001), and lower hospital costs (p = 0.03). Among 50 pairs of matched groups, significant differences were found only in operative time, hospital stay, and costs. Maximum tumor size and pathological features differed significantly before and after matching (all p < 0.05), with the lobar group consistently demonstrating a larger main tumor (median, 2.5 cm) and a higher percentage of primary lung cancer (84%). Multivariate logistic regression analysis showed that a longer operative time was the factor associated with more complications (OR: 1.01; 95% CI 1.00-1.02, p = 0.002). CONCLUSIONS: With regard to SBTLR, our data suggests that sublobectomy may reduce the prolonged recovery, hospital costs, and complications incurred by lobectomy, without compromising oncological outcomes.

BACKGROUND: According to recent animal models for lung adenocarcinoma metastasis, cardiac function may be related to the clinical outcome. The aim of this study is to identify a predictable index for postoperative metastasis (POM) that is associated with cardiac function. METHODS: Two hundred and seven consecutive patients who underwent thoracoscopic resection for stage I lung adenocarcinoma were included. Disease-free survival (DFS), overall survival (OS), and patients' clinical and pathological characteristics were analyzed. RESULTS: Among the 207 patients, 17 cases demonstrated metastasis, 110 cases received a preoperative echocardiogram, and six cases had POM. Mitral valve peak A velocity, which is one of the left ventricular diastolic function parameters affected by BMI (MVPABMI), was associated with a negative factor for POM (hazard ratio (HR): 2.139, p = 0.019) and a poor 5-year DFS in the above median (100% vs. 87%, p = 0.014). The predictable rate increased from 30.7% to 75% when the MVPABMI was above the median = 3.15 in the solid subtype). CONCLUSIONS: MVPABMI is a novel index for POM prediction in early-stage lung adenocarcinoma. This is a pilot study and the first attempt at research to verify that the diastole and the BMI may be associated with POM in early-stage lung adenocarcinoma.
RESUMEN
Postoperative pulmonary complications (PPCs) most commonly occur after thoracic surgery. Not only prolonged hospital stay and increased financial expenses but also morbidity and even mortality may be troublesome for those with PPCs. Herein, we aimed to conduct a comprehensive systematic review and meta-analysis of available data to examine the effectiveness of incentive spirometry (IS) to reduce PPCs and shorten hospital stay. This systematic review and meta-analysis included 5 randomized controlled trials (RCT) and 3 retrospective cohort study (10,322 patients in total) in PubMed, Embase and Cochrane Library until September 31, 2021. We assessed the clinical efficacy of IS using length of hospital stay, PPCs, postoperative pneumonia, and postoperative atelectasis with meta-analysis, meta-regression and trial sequential analysis (TSA). With this meta-analysis, the length of hospital stay in patients undergoing IS was significantly shorter (1.8 days) than that in patients not receiving IS (MD = -1.80, 95% CI = -2.95 to -0.65). Patients undergoing IS also had reduced risk of PPCs (32%) and postoperative pneumonia (17.9%) with statistical significance than patients not undergoing IS (PPC: OR = 0.68, 95% CI = 0.51-0.90) (Pneumonia: OR = 0.821, 95% CI = 0.677-0.995).In meta-regression, the benefits of undergoing IS in patients with preoperative predicted FEV1 of <80% in a linear fashion with decreasing PPCs. IS is an effective modality to improve the quality of postoperative care for patients after pulmonary resection, compared with the control group without using IS; and applying IS has favorable outcomes of shorter length of hospital stay (1.8 days) and lower occurrence of PPCs (32% of risk reduction), which are conclusive and robust based on our validation via TSA. Moreover, the IS device is more beneficial for patients with preoperative predicted FEV1 of <80% than that in others.

BACKGROUND: Resection is the current treatment of choice for resectable bilateral pulmonary metastases. This study aimed to compare the differences in outcomes between simultaneous bilateral open and video-assisted thoracic surgery (VATS) for pulmonary metastasectomy. METHODS: Forty-three patients underwent pulmonary metastasectomy through one-stage bilateral open thoracotomy (n = 16) and VATS (n = 27) between 2011 and 2020. Perioperative and oncological data were analyzed. RESULTS: The predominant primary tumor histology in both groups was colorectal cancer. The operative time, blood loss, and pain score on postoperative day 1 (POD1) were higher in the open group (p < 0.001, 0.009, and 0.03, respectively). No significant differences in pain score on POD2 and POD3, postoperative length of stay, or complications were found. Notably, numbers of the resected metastatic lung nodules were significantly greater in the open group (median number: 9.5 vs. 3, p < 0.001). Recurrence-free survival (RFS) and overall survival (OS) were comparable. The median RFS was 15 months (interquartile range [IQR], 6-22) in the open group and 18 months (IQR, 8-47) in the VATS group. The median OS was 28 months (IQR, 14-44) and 29 months (IQR, 15-54) in the open group and VATS group, respectively. CONCLUSION: One-stage bilateral pulmonary metastasectomy is safe and reduces medical expenditures in selected patients regardless of surgical approach. Although the open group harbored a greater number of metastatic foci, perioperative and oncological outcomes were similar to that of the VATS group.

BACKGROUND: Completion lobectomy (CL) after anatomical segmentectomy is technically challenging and rarely performed. Here, we aimed to report perioperative outcomes of a single center real-world CL data. METHODS: Seven patients who underwent CL after segmentectomy were retrospectively evaluated between 2015-2021. Additionally, 34 patients were included in the review based on relevant studies in the literature until March 2022. A total of 41 patients were finally analyzed and classified into groups, according to surgical approach (video-assisted thoracic surgery [VATS] and thoracotomy; 12 and 29 patients, respectively) or interval-to-CL following initial segmentectomy (≤8 weeks [short] and >8 weeks [long]; 11 and 30 patients, respectively). RESULTS: There were no significant differences in estimated blood loss, postoperative hospital stay, or complications between the predefined groups. However, a longer operative time was observed in the long interval-to-CL group than in the short interval-to-CL group (267 vs. 226 min, p = 0.02). The rate of severe hilar adhesions was higher in the thoracotomy versus VATS groups (72 vs. 42%, p = 0.06) and in the long versus short interval-to-CL groups (70 vs. 45%, p = 0.15). On multivariable logistic regression analysis of a subgroup (n = 30), completion lobectomy of upper lobes may be associated with severe hilar adhesions (p = 0.02, odds ratio: 13.98; 95% confidence interval [CI]: 1.36-143.71). CONCLUSION: Completion lobectomy after segmentectomy can be performed securely by either VATS or thoracotomy. Although the thoracotomy and long interval-to-CL groups retained a greater percentage of severe hilar adhesions, the perioperative outcomes were similar to those of VATS and short interval-to-CL groups, respectively.

Hyperbaric oxygen therapy (HBOT) has been suggested as a potential adjunctive therapy for Parkinson's disease (PD). PD is a neurodegenerative disease characterized by the progressive loss of dopaminergic neurons in the substantia nigra pars compacta (SNpc). The aim of this study was to investigate the protective mechanisms of HBOT on neurons and motor function in a 1-Methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) mouse model of PD and 1-methyl-4-phenylpyridinium (MPP+)-mediated neurotoxicity in SH-SY5Y cells on the potential protective capability. In vivo: male C57BL/6 mice were randomly divided into three groups: control, MPTP group and MPTP+HBOT group. The MPTP-treated mice were intraperitoneally received MPTP (20 mg/kg) four times at 2 h intervals within a day. The day after MPTP treatment, MPTP+HBOT mice were exposed to hyperbaric oxygen at 2.5 atmosphere absolute (ATA) with 100% oxygen for 1 h once daily for 7 consecutive days. In vitro: retinoic acid (RA)-differentiated SH-SY5Y cells were treated with MPP+ for 1 h followed by hyperbaric oxygen at 2.5 ATA with 100% oxygen for 1 h. The results showed that MPTP induced a significant loss in tyrosine hydroxylase (TH)-positive neurons in the SNpc of mice. HBOT treatment significantly increased the number of TH-positive neurons, with enhanced neurotrophic factor BDNF, decreased apoptotic signaling and attenuated inflammatory mediators in the midbrain of MPTP-treated mice. In addition, MPTP treatment decreased the locomotor activity and grip strength of mice, and these effects were shown to improve after HBOT treatment. Furthermore, MPTP decreased mitochondrial biogenesis signaling (SIRT-1, PGC-1α and TFAM), as well as mitochondrial marker VDAC expression, while HBOT treatment was shown to upregulate protein expression. In cell experiments, MPP+ reduced neurite length, while HBOT treatment attenuated neurite retraction. Conclusions: the effects of HBOT in MPTP-treated mice might come from promoting mitochondrial biogenesis, decreasing apoptotic signaling and attenuating inflammatory mediators in the midbrain, suggesting its potential benefits in PD treatment.

There is a lack of data comparing postoperative pain after subxiphoid and intercostal video-assisted thoracoscopic surgery (VATS). Pain is an individual's subjective experience and, therefore, difficult to compare between different individuals subjected to either procedure. This study assessed reported pain at six postoperative time points in the same patients receiving both subxiphoid and intercostal incisions for thoracic disease. Data from 44 patients who received simultaneous combined intercostal and subxiphoid VATS were retrospectively analyzed from August 2019 to July 2021. All patients received the same length of subxiphoid and intercostal incisions with or without drain placements. A numerical pain rating scale was administered on postoperative days (POD)-1, POD-2, POD-Discharge, POD-30, POD-90, and POD-180. Bilateral uniportal VATS was performed in 11 patients, and unilateral multiportal VATS was performed in 33 patients. In the unilateral VATS group, there were no differences in pain reported for both incisions in the early postoperative period. However, in the bilateral VATS group, subxiphoid wounds resulted in significantly higher pain scores on POD-1, POD-2, and POD-Discharge (p = 0.0003, 0.001, and 0.03, respectively). Higher late (3 and 6 months) postoperative pain was associated with intercostal incisions in both groups, as previously reported, whereas higher early (day 1, 2, and discharge) postoperative pain was more associated with subxiphoid incisions than intercostal incisions in the bilateral VATS group.
RESUMEN
OBJECTIVE: The chest tube drainage system (CTDS) of choice for the pleural cavity after pulmonary resection remains controversial. This systematic review and network meta-analysis (NMA) aimed to assess the length of hospital stay, chest tube placement duration, and prolonged air leak among different types of CTDS. METHODS: This systemic review and NMA included 21 randomized controlled trials (3399 patients) in PubMed and Embase until 1 June 2021. We performed a frequentist random effect in our NMA, and a P-score was adopted to determine the best treatment. We assessed the clinical efficacy of different CTDSs (digital/suction/non-suction) using the length of hospital stay, chest tube placement duration, and presence of prolonged air leak. RESULTS: Based on the NMA, digital CTDS was the most beneficial intervention for the length of hospital stay, being 1.4 days less than that of suction CTDS (mean difference (MD): -1.40; 95% confidence interval (CI): -2.20 to -0.60). Digital CTDS also had significantly reduced chest tube placement duration, being 0.68 days less than that of suction CTDSs (MD: -0.68; 95% CI: -1.32 to -0.04). Neither digital nor non-suction CTDS significantly reduced the risk of prolonged air leak. CONCLUSIONS: Digital CTDS is associated with better outcomes than suction and non-suction CTDS for patients undergoing pulmonary resections, specifically 0.68 days shorter chest tube duration and 1.4 days shorter hospital stay than suction CTDS.
RESUMEN
Esophageal squamous cell carcinoma (ESCC) is a highly aggressive tumor known to have locally advanced and metastatic features which cause a dismal prognosis. We sought to determine whether elafin, a non-invasive and secretory small-molecule marker, could be used to predict prognosis in locoregional ESCC patients in human and in vitro studies. In our human study, 119 subjects were identified as having incident and pathologically-proved ESCC with stage I-IIIA tumors from southern Taiwan between 2000 and 2016. We measured their serum elafin levels at baseline and followed them until the date of cancer death or until January 2020, the end of this study. Those with high serum elafin levels were found to have a 1.99-fold risk (95% confidence interval: 1.17-3.38) shorter survival than those who did not. In our in vitro experiments, elevated elafin levels were found to drive ESCC cell proliferation, migration and invasion, while attenuation of elafin level by shRNA abrogated those effects. We concluded that elafin promotes ESCC motility and invasion and leads to a worse clinical prognosis in ESCC patients without distant metastasis.
RESUMEN
BACKGROUND: In adults with primary spontaneous pneumothorax (PSP), contralateral recurrence occurs in about 25-28% when there are asymptomatic blebs. How to treat contralateral recurrence of PSP in pediatric populations remains controversial. This study evaluated the outcomes of excising contralateral blebs to prevent recurrence in adolescents being operated on for PSP under the same anesthesia. METHODS: One hundred thirty-two male PSP patients under age 19 were surgically treated in a single institution between January 2008 and December 2016. Thoracoscopic blebectomies with pleurodesis were performed in all patients. The patients were categorized into those with contralateral blebs receiving one-stage bilateral surgeries (32 patients), those with contralateral blebs only receiving unilateral surgeries (40 patients), and those without contralateral blebs only receiving unilateral surgeries (60 patients). Perioperative details and outcomes were retrospectively analyzed. RESULTS: Significant differences in contralateral recurrence rate were found among the three groups (0%, 30%, and 1%, respectively; P < 0.001). Multivariate analysis showed that being under 16.5 years old was a risk factor for overall recurrence (Hazard ratio [HR] 2.81, 95% confidence interval [CI] 1.08-7.30, P = 0.034). Moreover, patients who had contralateral blebs and only received unilateral surgery were at greater risk of overall recurrence (HR 6.06, 95% CI 1.77-20.75, P = 0.004). Kaplan-Meier analysis showed that contralateral and overall recurrence-free survival differed among the three groups (P < 0.0001, P = 0.0002). CONCLUSIONS: Although younger male PSP adolescents treated with surgery were more likely to have postoperative recurrences, the performance of simultaneous contralateral blebectomies in those receiving one-stage bilateral surgeries significantly reduced future contralateral recurrence without compromising patient safety.

Very little data exists on salvage surgery in previously unresectable or metastatic disease treated with initial immunotherapy. Only a handful of case reports/series regarding surgery for advanced lung cancer after immunotherapy mention the technical challenges involved. We report the case of a 67-year-old female with a left lung squamous cell lung cancer revealed by computed tomography-guided biopsy. Treatment started with chemotherapy followed by immunotherapy in which a partial response was recorded. Subsequent salvage lingulectomy with the thoracoscopic approach was performed. The patient fully recovered and shows no sign of recurrence at follow-up 16 months on. Our case discusses the surgical tactics involved in the procedure, highlights similar findings encountered in the literature, and contributes to the few reports therein.

BACKGROUND: The omission of chest tubes after thoracoscopic procedures such as sympathectomy, lung biopsy, and lung resection has proven efficacious in decreasing pain and length of hospital stay in some cases. However, its safety for mediastinal diseases remains unclear. This study evaluated the feasibility and outcome of eliminating chest drains after video-assisted thoracoscopic surgery (VATS) for mediastinal tumor resection. METHODS: We retrospectively investigated 70 patients receiving VATS mediastinal tumor resection in a single institution between January 2016 and November 2018. A total of 39 patients (drain group) received postoperative chest drains and 31 patients (no-drain group) did not. Group clinical outcomes and operation data were compared. A propensity score matching analysis was further performed to yield a fairer comparison. RESULTS: Before propensity score matching, the no-drain group had a higher prevalence of cystic lesions, a shorter operative time, and less blood loss compared with the drain group (p = 0.015, p = 0.018, and p < 0.001, respectively). After matching, the group differences in these perioperative variables lost significance (p = 0.095, 0.4, and 0.2, respectively). The no-drain group had lower postoperative day 2 pain scores and shorter postoperative hospital stays than the drain group, regardless of whether they were matched (pain: p = 0.028; hospital stay < 0.001) or not (pain: p = 0.003; hospital stay < 0.001). No major adverse events occurred in either group during hospitalization or follow-up period. CONCLUSION: Eliminating chest drain placement after VATS mediastinal tumor resection may benefit some patients and decrease postoperative pain and hospital stay without increasing complications or compromising patient safety.

BACKGROUND: Persistent tracheocutaneous fistula (TCF) is a complication of prolonged use of tracheostomy tube. Although many procedures exist to correct this issue, there is no consensus regarding its optimal management. We constructed a decision algorithm to determine appropriate surgical strategies for TCF repair. METHODS: Retrospectively reviewing our hospital's records, we found fourteen consecutive patients who had received surgical repair of tracheocutaneous fistula (primary closure or advanced local flap) between February 2013 and December 2018 and collected data relevant to their cases. RESULTS: We identified 11 male and 3 female patients. Duration of tracheostomy dependence was 8.1±4.7 months, and timespan from decannulation to surgical closure 7.4±6.5 months. Seven patients received primary closures, six received hinged turnover flaps, and one received random and perforator flap reconstruction. There was no perioperative mortality or morbidity except for one patient requiring a repeat tracheostomy 11 months after TCF repair due to pneumonia and subsequent respiratory failure. We used our findings and those reported in the literature to construct a modified risk factor scoring system based on patient's physical status, major comorbidities, perifistular soft tissue condition, and nutritional status and an algorithm for managing TCF based on the patients' fistula size and modified risk factor scores. CONCLUSIONS: In conclusion, we were able to review our cases and those of other studies to create a risk scoring system and a decision algorithm that we believe will help optimize patient-directed surgical management of TCF repair.
RESUMEN
This report describes the case of a 17-year-old man who developed mediastinal growing teratoma syndrome following two cycles of chemotherapy, after an initial diagnosis of primary mediastinal nonseminomatous germ cell tumor. The large, rapidly-growing mediastinal tumor was completely resected in conjunction with right pneumonectomy, using simultaneous clamshell thoracotomy and median sternotomy. The salvage surgery with perioperative management involved in mediastinal growing teratoma syndrome is presented here. KEY POINTS: Significant findings of the study The diagnosis and surgical management are challenging for patients with mediastinal growing teratoma syndrome. Nevertheless, with proper operative planning, favorable outcomes can be attained with complete resection despite the characteristic rapid growth and massive size of these neoplasms. What this study adds In spite of postoperative sternal dehiscence, we believe that a simultaneous clamshell thoracotomy with median sternotomy approach remains a viable option for an extremely large mediastinal growing teratoma, when tumor size prevents safe resection using other approaches due to limited visualization.

OBJECTIVE: Contralateral recurrence in patients with primary spontaneous pneumothorax is approximately 15%. If positive for blebs, the recurrence rate increases to 26%. This study seeks to determine whether simultaneous contralateral video-assisted thoracic surgery blebs excision would effectively lower the contralateral incidence of pneumothorax in patients undergoing surgery for ipsilateral primary spontaneous pneumothorax. METHODS: Between January 2009 and December 2015, 335 patients with primary spontaneous pneumothorax, surgically treated in a single institution, were retrospectively studied. The median follow-up was 75 (50-99) months. All patients received video-assisted thoracic surgery blebectomy/bullectomy with pleural abrasions. They were classified into 3 groups: (1) ipsilateral video-assisted thoracic surgery without contralateral blebs/bullae included 142 patients with ipsilateral primary spontaneous pneumothorax without contralateral blebs/bullae only receiving ipsilateral video-assisted thoracic surgery; (2) ipsilateral video-assisted thoracic surgery with contralateral blebs/bullae included 123 patients with ipsilateral primary spontaneous pneumothorax with contralateral blebs/bullae receiving only ipsilateral video-assisted thoracic surgery; and (3) bilateral video-assisted thoracic surgery with contralateral blebs/bullae included 70 patients with ipsilateral primary spontaneous pneumothorax with contralateral blebs/bullae receiving 1-stage bilateral video-assisted thoracic surgery. Demographic data, perioperative details, recurrence patterns, recurrence-free survivals, and risk factors were compared. RESULTS: The percentage of contralateral recurrence for the ipsilateral video-assisted thoracic surgery without contralateral blebs/bullae, ipsilateral video-assisted thoracic surgery with contralateral blebs/bullae, and bilateral video-assisted thoracic surgery with contralateral blebs/bullae groups differed significantly (0.7%, 14.6%, and 2.9%, respectively; P = .002). Multivariate analysis using the Cox proportional hazard model revealed that age less than 18 years (hazard ratio, 2.71; 95% confidence interval, 1.14-6.44; P = .024) and ipsilateral video-assisted thoracic surgery with contralateral blebs/bullae (hazard ratio, 22.13, 95% confidence interval, 2.96-165, P = .003) were predictors of contralateral recurrence, of which recurrence-free survival was notably different among groups as determined by Kaplan-Meier analysis (P < .0001). CONCLUSIONS: Simultaneous contralateral blebectomy in patients with primary spontaneous pneumothorax receiving ipsilateral video-assisted thoracic surgery significantly lowered future contralateral recurrence.

This report describes the surgical management of a male patient with early-stage lung cancer who underwent thoracoscopic completion right lower lobectomy after previously undergoing sublobar resection for multifocal ground glass nodules of the lung. Perioperative considerations associated with the management of dense pulmonary hilar adhesions and the techniques used are discussed.
