BackgroundSurgical treatment of stage I non-small cell lung cancer (NSCLC) can be performed either by thoracotomy or by employing video-assisted thoracic surgery (VATS). The aim of this study was to evaluate the feasibility of VATS lobectomy for pathologic stage I NSCLC.Material and MethodsBetween December 2003 and December 2007, 529 patients with pathologic stage I NSCLC underwent lobectomies (373 thoracotomy, 156 VATS). Patients in both groups were selected after being matched by age, gender and pathologic stage using propensity score method, to create two comparable groups: thoracotomy and VATS groups, and the overall survival, recurrence-free survival, complication and length of hospitalization were compared between these two groups.ResultsAfter the patients were matched by age, gender and pathologic stage, 272 patients remained eligible for analysis, 136 in each group (mean age of 59.5 years; 70 men, 66 women; 80 stage IA, 56 stage IB). There was no statistical difference in other preoperative clinical characteristics between the two groups. No hospital mortality was observed in both groups. Overall 3-year survival rate was 97.4% in thoracotomy group and 96.6% in VATS groups (p=0.76). During the follow-up, 20 patients (14.7%) developed recurrence in thoracotomy group, including loco- regional recurrence in 7, distant metastasis in 13. In VATS group, 13 patients (9.6%) developed recurrence, including loco-regional recurrence in 4, distant metastasis in 9. Three-year recurrence-free survival rate was 81.8% in thoracotomy group and 85.3% in VATS groups (p=0.43). There was no significant difference in postoperative complications between thoracotomy and VATS groups (30 cases in 22 patients vs. 19 cases in 17 patients, p=0.65, odds ratio=1.19). The mean hospital stay of VATS group was 2 days shorter than that of thoracotomy group (8.8±6.5 days vs. 6.3±3.3 days, p<0.05).ConclusionVATS lobectomy for pathologic stage I lung cancer is a feasible operation with shorter hospitalization, while surgical outcome is comparable to thoracotomy lobectomy.
Thoracoscopic wedge resection alone successfully controlled primary spontaneous pneumothorax. Additional pleural abrasion did not decrease the recurrence of pneumothorax after wedge resection of bullae for primary spontaneous pneumothorax. Younger age was associated with higher risk of recurrence.
BackgroundTreatment of pulmonary metastasis from urothelial cell carcinoma has been mostly palliative chemotherapy and the role of pulmonary metastasectomy has not been investigated much.Materials and MethodsThis study is a retrospective interim review of pulmonary metastasectomy from urothelial carcinoma at single institution between 1998 and 2010. Overall 16 patients underwent pulmonary metastasectomies.ResultsThere was no postoperative complication or hospital mortality. Mean hospital stay was 6 days. Overall and disease-free 5-year survival were 65.3% and 37.5%, respectively.ConclusionIn selected patients with pulmonary metastasis from urothelial carcinoma, surgical treatment is feasible and could contribute to long-term survival in selected patients.
Anomalous origin of a coronary aortic artery is a rare cardiac anomaly. Although it can cause angina, syncope, and palpitations, most patients are asymptomatic. This anomaly requires surgical treatment or intervention because it is associated with sudden death. Several surgical techniques, such as coronary reimplantation, coronary artery bypass grafting (CABG), unroofing, and neo-ostium formation, have been proposed as treatments. We report a case surgically treated with neo-ostium formation in anomalous origin of the left coronary artery from the right coronary sinus.
The ENB-guided dye localization by a well-trained thoracic surgeon enables accurate intraoperative identification of GGN or a small pulmonary nodule, with minimal complications and enables minimally invasive surgery including single port surgery.
Background/Aims: The aim of our study was to define the potential role of virologic response at 12 months of treatment (VR12) in predicting subsequent virologic and clinical outcomes in adefovir (ADV)-treated lamivudine-resistant chronic hepatitis B. Methods: Two hundred and four patients with lamivudine-resistant chronic hepatitis B virus (HBV) treated with ADV monotherapy were included. Serum HBV DNA was quantified by real-time polymerase chain reactions. VR12 was defined as a HBV DNA level of less than 4 log10 copies/mL after 12 months of ADV treatment. Results: VR12 was observed in 110 of the 204 patients (54%). The mean HBV DNA reductions from baseline after 12 months of ADV treatment were 3.8 and 1.9 log10 copies/mL in patients with and without VR12, respectively (p<0.001). The hepatitis B "e" antigen (HBeAg) seroconversion rates in patients with and without VR12 were 32% and 14% at 12 months treatment, respectively (p=0.018), and 40% and 27% at 24 months of treatment (p=0.032). The genotypic mutation rates to ADV in patients with and without VR12 were 0% and 6% at 12 months of treatment, respectively (p=0.033), and 21% and 42% at 24 months (p= 0.012). The rates of viral breakthrough in patients with and without VR12 were 0% and 7% at 12 months of treatment, respectively (p=0.072), and 9% and 25% at 24 months (p=0.006). Conclusions: Patients without VR12 may need to switch to or add on other potent antiviral drugs in their medical regimens. (Gut Liver 2010;4:212-218)
A 3-year-old girl with acute respiratory distress syndrome due to a H1N1 2009 influenza virus infection was complicated by necrotizing pneumonia was successfully treated with extracorporeal membrane oxygenation (ECMO). This is the first reported case in which a pediatric patient was rescued with ECMO during the H1N1 influenza epidemic in Korea in 2009.
Postpneumonectomy empyema is a life-threatening complication, which is often related with a bronchopleural fistula. After surgical repair of fistula, sterilization of infected pleural cavity is important and usually carried out by long-term cyclic irrigation. We report a case in which vacuum-assisted closure device was successfully applied to sterilize the pleural cavity and obliterate bronchopleural fistula.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
