RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

RATIONALE: Angiomatosis is a rare non-neoplastic proliferative vascular lesion that typically develops during childhood or adolescence with a female predominance. Management of angiomatosis is challenging because of the manifestation of a wide variety of lesions as well as their invasive and highly recurrent nature. PATIENT CONCERNS: We report the case of a 74-year-old man who presented with a right lower back mass that persisted for a decade. The mass progressively enlarged and had been painful in the previous month. DIAGNOSIS: Computed tomography (CT) revealed suspected lipomatous sarcoma with invasion of the ribs, pleurae, and lung parenchyma. The final pathological examination revealed angiomatosis. INTERVENTIONS: The patient underwent wide composite excision of the tumor along with excision of the pleura and lung nodules in the right lower and middle lobes via video-assisted thoracoscopic surgery (VAST). Fasciocutaneous rotational flap reconstruction was performed immediately after the wide composite excision and video-assisted thoracoscopic surgery (VAST). OUTCOMES: The patient recovered uneventfully, was discharged without complications, and tolerated the daily activities well. LESSONS: Angiomatosis is a rare benign vascular tumor that frequently mimics malignancy. Even if the patient profile does not match the reported epidemiology of this disease, differential diagnosis should be considered. Complete resection is the mainstay of treatment for the prevention of recurrence.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

BACKGROUND AND AIMS: This study prospectively recruited esophageal squamous cell carcinoma patients who received esophageal stent, nasogastric tube (NGT), or jejunostomy/gastrostomy feeding to compare the changes in nutritional status and quality of life during chemoradiation therapy (CRT). METHODS: In total, 81 patients were analyzed (stent, 7; surgical ostomy, 26; NGT, 19; oral intake, 29). An NGT was inserted when, despite medication, dysphagia or pain worsened with oral feeding during CRT. Serial body weight and daily narcotic demand were recorded. Changes in serum albumin level and quality of life were also assessed. In subgroup analysis comparing NGT and prophylactic surgical ostomy feeding, 5 patients with total occlusion in the ostomy group were excluded. RESULTS: Patients in all groups had similar decreases in mean body weight with an overall change of -6.41% ± 5.21% at the end of CRT. The stent group had significantly worse pain, decreased albumin (-1.03 ± .9 mg/dL), and decreased quality of life across CRT compared with the other groups. In subgroup analysis the stent group had significantly higher weight loss, whereas the NGT group had higher narcotic demand and slightly worse quality of life. Two patients (7.7%) had ileus days after jejunostomy creation. Five patients (23.8%) among those received prophylactic ostomy creation and scarcely used it. CONCLUSIONS: These preliminary results raise concerns that use of esophageal stents may be less suitable in patients undergoing CRT. Tube feeding by means of transnasal or percutaneous routes appear to be comparably effective during CRT, but both have advantages and disadvantages. We suggest a careful endoscopic evaluation to select the population more appropriate for NGT feeding on an as-needed basis during CRT.

RESUMO

BACKGROUND: Surgery for esophageal cancer is invasive and challenging, and always to be followed with arduous post-operative care and recovery. This study, maybe one of the first in Asian populations, is to determine whether a reinvented protocol for perioperative management for esophageal cancer surgery which is being implemented in our department, will lead to a faster convalescence and also significantly decrease financial burdens garnered by patients during hospitalization. METHODS: Operated on by the same surgeon and team in the same hospital, consecutive patients who had received esophagectomy and reconstruction for esophageal squamous cell carcinoma were retrospectively reviewed. On the basis of two different treatment periods, patients were divided into two groups: A and B. Group A was patients who had received the new reinvented protocol between 2012 and 2016, while group B patients were those having received the previous protocol between 2008 and 2011. Their demographics, post-operative outcome, and hospital charges were collected and compared. RESULTS: There were 64 patients in group A, and 69 in group B. Ventilator days (P<0.001), ICU stay (P<0.001), and post-operative stay (P<0.001) were significantly shorter in group A patients. Complication rates were similar between the two groups. No hospital mortality was noted in either group. Hospital charges in group A were found to be perceptively lower, although not statistically significant (P value =0.078). CONCLUSIONS: The current protocol of perioperative care effectively ameliorated convalescence after esophagectomy and reconstruction for esophageal squamous cell carcinoma without increasing complication rate or mortality. It is also potentially more practical in future health care policies during this era of financial shortage.

RESUMO

BACKGROUND: Uniportal video-assisted thoracoscopic surgery (VATS) is increasingly being performed worldwide. During the operation, specimen extraction from a small incision less than or equal to 2 cm can be challenging without the use of a commercial specimen retrieval device. There have been no reports regarding the use of the glove-finger technique in uniportal VATS. The aim of this study was to assess the feasibility of the alternative specimen retrieval method by glove-finger technique. METHODS: We retrospectively investigated 50 patients with peripheral lung lesions who underwent uniportal VATS wedge resection with a 2-cm incision at Kaohsiung Medical University Hospital between August 2015 and December 2016. The cut end of the glove-finger was used to extract the specimen. RESULTS: Fifty-five wedge-resected specimens were extracted successfully by glove-finger technique. There was no conversion to two-port nor three-port VATS. After intraoperative frozen section analysis for all specimens, 24 were revealed to have primary lung cancer and subsequently underwent completion lobectomy or segmentectomy; the other 31 showed 10 pulmonary metastases, 9 pulmonary benign lesions, and 12 pulmonary infectious lesions. All specimens were resected with free margins and the mean diameter of the lesions was 1.64 ± 0.59 cm (range: 0.2-2.6 cm) by pathological examination. No intraoperative complication related to the technique was observed. CONCLUSIONS: This is the first study to reveal the efficacy and benefits of the glove-finger extraction technique in uniportal VATS. In our preliminary experience, this method can decrease costs without compromising the quality and safety of patient care.

RESUMO

OBJECTIVES: Postoperative recurrent primary spontaneous pneumothorax (PSP) is a troublesome complication and an important issue to be discussed. This study is to determine whether Re-video assisted thoracoscopic surgery (VATS) should be performed for postoperative recurrent PSP (PORP). MATERIALS AND METHODS: Patients who had underwent needlescopic VATS for PSP between Jan. 2007 and Dec. 2011 were reviewed. RESULTS: VATS was initially performed on 239 patients with PSP in total. Eleven patients were found to have PORP during a follow-up period of 36.95 months. Nine patients received Re-VATS and only two patients receiving conservative treatment had no further recurrence. No conversion to thoracotomy, blood transfusion and prolong air leak were recorded. CONCLUSIONS: Even for smaller size cases, Re-VATS, which is technically feasible, safe and effective with better cosmetics and minor postoperative pain, should be a strong contender as priority treatment.

RESUMO

BACKGROUND: Lung ischemia-reperfusion (I/R) injury plays an important role in lung transplantation. Less well known is the role of sildenafil in lung I/R injury; therefore, we attempted to determine whether sildenafil could alleviate lung apoptosis and tissue injury in a rat model. METHODS: Forty male Sprague-Dawley rats were randomized into four groups: saline + sham, saline + I/R, sildenafil + sham, and sildenafil + I/R groups. Three hours before the operation, each rat received normal saline or sildenafil (10 mg/kg) by lavage. The animals designed to I/R injury were subjected to 2 h of ischemia induced by occlusion of left pulmonary artery, veins, and bronchus, followed by reperfusion for 2 h. The lung tissue was harvested for the analysis of the expression of Bax, Bcl-2, p53, caspase 3, tumor necrosis factor (TNF)-alpha, interleukin (IL)-6, and wet/dry (W/D) weight ratio. RESULTS: Compared with the saline + sham group, the saline + I/R group had significant increases in Bax, p53, Bax/Bcl-2 ratio, caspase 3, IL-6, TNF-α, and W/D weight ratio but a decrease in Bcl-2 (P < 0.05). Compared with the saline + I/R group, sildenafil + I/R group had significant decreases in Bax, p53, Bax/Bcl-2 ratio, caspase 3, IL-6, TNF-α level, and W/D weight ratio but an increase in Bcl-2 expression (P < 0.05). Compared with the sildenafil + sham group, there were significant increases in p53 and TNF-α expression in the sildenafil + I/R group (P < 0.05). CONCLUSIONS: Pretreatment with sildenafil alleviates lung apoptosis and tissue injury in a rat model.

RESUMO

Esophageal squamous cell cancer (ESCC) is one of the most common fatal human cancers. The identification of biomarkers for early detection could be a promising strategy to decrease mortality. Previous studies utilized microarray techniques to identify more than one hundred genes; however, it is desirable to identify a small set of biomarkers for clinical use. This study proposes a sequential forward feature selection algorithm to design decision tree models for discriminating ESCC from normal tissues. Two potential biomarkers of RUVBL1 and CNIH were identified and validated based on two public available microarray datasets. To test the discrimination ability of the two biomarkers, 17 pairs of expression profiles of ESCC and normal tissues from Taiwanese male patients were measured by using microarray techniques. The classification accuracies of the two biomarkers in all three datasets were higher than 90%. Interpretable decision tree models were constructed to analyze expression patterns of the two biomarkers. RUVBL1 was consistently overexpressed in all three datasets, although we found inconsistent CNIH expression possibly affected by the diverse major risk factors for ESCC across different areas.

RESUMO

Whether the outcome of primary spontaneous pneumothorax (PSP) when treated with needlescopic video-assisted thoracic surgery is positive is still under scrutiny. The present study was conducted to compare the needlescopic approach with the conventional approach. One-hundred and six patients with primary spontaneous pneumothorax who had undergone needlescopic video-assisted thoracic surgery (NVATS) between May 2006 and August 2008 were reviewed. Their age, gender, smoking status, BMI, side of attack, operative indications, operative time, intraoperative blood loss, postoperative length of stay, postoperative pain in visual analog scale (VAS), postoperative recurrence and follow-up period were recorded. These data were compared with those of 89 patients with PSP who had undergone conventional video-assisted thoracic surgery (CVATS) between June 2002 and April 2006. The operative time was shorter (NVATS: 82.36 ± 35.58 min, CVATS: 99.78 ± 35.74 min; p = 0.008) and intraoperative blood loss was less (NVATS: 16.67 ± 25.90 ml, CVATS: 24.36 ± 26.86 ml; p = 0.04) for the NVATS group. The postoperative pain in VAS was significantly less in NVATS. No major complication or mortality was found in either group. For treatment of primary spontaneous pneumothorax, NVATS is a safe and effective option. Further, it has the added benefit of less pain and improved cosmetics.

RESUMO

Most aorto-respiratory fistulas are related to aortic pathology or procedures, but fistula formation after esophageal resection has never been reported in the literature. We are now reporting a case of hemoptysis that occurred after esophagectomy for locally advanced esophageal cancer. Aortobronchial fistula was detected by computed tomography scan. The patient was finally saved by emergency surgery-Dacron graft interposition of the descending thoracic aorta. There was no malignant cell in the postoperative specimen of the fistula. The erosion of the ligaclips (Johnson & Johnson) might be responsible for the aortobronchial fistula formation. For esophageal surgery, avoidance of trauma to aortic wall and careful using of ligaclips are important to circumvent this complication.

RESUMO

OBJECTIVES: The aim of this study was to identify the preoperative factors that affect the survival of patients who undergo esophagogastrectomy after corrosive ingestion, using analysis of their physiological condition, associated diseases, physical examination, and laboratory data. METHODS: Between January 1995 and December 2005, 71 consecutive patients who underwent esophagogastrectomy for corrosive ingestion injuries were retrospectively reviewed. Of them, 41 survived and 30 (42.3%) died during the perioperative period. Logistic regression analyses were used to model markers for postoperative mortality, including descriptive data, clinical symptoms/signs, and laboratory data. RESULTS: There were 35 males and 36 females included in the study, with an average age of 54.7 +/- 14.9 years. After adjustments in the logistic regression model, age of over 65 years (p = 0.021), presence of gross hematuria (p = 0.016), twofold level of serum AST (p = 0.012), blood pH level below 7.2 (p = 0.017), and deficit of blood base over 16 (p = 0.007) were found to be independent risk factors for patient mortality. CONCLUSIONS: We consider age over 65 years, preoperative pH < 7.2, base deficit >16, twofold level of serum AST, and presence of gross hematuria to be the important factors predicting postoperative hospital mortality in patients presenting with corrosive ingestion injuries who require emergency surgery.

RESUMO

BACKGROUND: The prognosis and quality of life (QOL) for those with cervical esophageal cancer is extremely poor, and chemoradiotherapy remains the mainstay treatment. During the past few years, our surgical teams has implemented a more aggressive and radical resection: total laryngopharyngectomy with neck dissection, total esophagectomy, and reconstruction with stomach. This study compares the results of chemoradiotherapy and that of the aforementioned surgical approach. METHODS: This is a retrospective study of 15 patients who underwent radical resection and 14 patients who received chemoradiation. Their age, sex, tumor stage and grade, pre- and posttreatment dysphagia scores, operating time, blood loss, length of intensive care and postoperative stay, days to resume oral intake, complications, Eastern Cooperative Oncology Group (ECOG) status, QOL score, and disease-specific survival were recorded and compared. RESULTS: There were no significant differences in age, sex, pretreatment dysphagia score, cancer stage and grade, ECOG status (posttreatment), associate diseases, preoperative QOL, or follow-up period between the two groups. However, the posttreatment dysphagia score was significantly better for the operative group (P < 0.001). QOL improved in both groups, and the operative group seemed better although the difference was not significant. In addition, the survival between the two groups was statistically insignificant (P = 0.97, log-rank test). CONCLUSIONS: Our experience showed that radical surgery that includes total laryngopharyngectomy with neck dissection, total esophagectomy, and reconstruction with stomach for cervical esophageal cancer is beneficial to patients in terms of better eating.

RESUMO

OBJECTIVES: More than 50% of patients with primary spontaneous pneumothorax have contralateral blebs/bullae, and about a quarter will develop a contralateral pneumothorax. The purpose of this prospective study was to determine the need for elective treatment of asymptomatic contralateral blebs/bullae in patients presenting with primary spontaneous pneumothorax. METHODS: From May 2006 through June 2008, results from 35 patients with ipsilateral primary spontaneous pneumothorax without contralateral blebs receiving unilateral video-assisted thoracic surgery, 35 patients with ipsilateral primary spontaneous pneumothorax with contralateral blebs receiving unilateral video-assisted thoracic surgery, and 16 patients with ipsilateral primary spontaneous pneumothorax receiving bilateral video-assisted thoracic surgery for positive contralateral blebs were collected. Their demographic and operating data were also recorded. RESULTS: There was no significant difference in age, gender, smoking percentage, body mass index (kg/m(2)), blood loss, and postoperative pain among groups. There was longer operative time and length of stay in group receiving bilateral surgery. Within the follow-up period of 16.68 +/- 9.91 months (median, 17.50), no recurrence on either lung was found in the group operated on both sides, while contralateral occurrence was found in 17.14% of the group with ipsilateral primary spontaneous pneumothorax with contralateral blebs receiving unilateral video-assisted thoracic surgery within the period of 18.15 +/- 8.07 months (median, 21). CONCLUSION: The study showed that the preemptive video-assisted thoracic surgery for the contralateral blebs/bullae effectively prevented the contralateral occurrence.
