    Analysis of pulmonary hydatidosis according to their segmentary locations
    (2008) Kocer B.; Gulbahar G.; Han S.; Ilhan M.N.; Dural K.; Sakinci U.
    The objective of this analysis is to compare the pulmonary locations of lung hydatid cysts and their size with respect to their locations with available literature. The records of 82 patients who were operated for pulmonary hydatid cysts between January 2001 and December 2005 were retrospectively evaluated. One hundred eleven cysts detected in 82 patients were placed into 2 groups as those located in the right lung (group A, 55 cysts) and those located in the left lung (group B, 56 cysts), and the segments involved were investigated. The gender distribution of the patients was 40 male and 42 female, with a mean age of 35.2 ± 17.64 years (range: 7-82 years). No difference was detected with respect to involvement between the 2 lungs (P = 0.285). The most commonly involved segment was the posterior basal segment of the lower lobe with 15 cysts (27.3%) from group A and 20 cysts (35.7%) from group B. No involvement of the lower lobe medial basal and anteromedial basal segments was observed. The most common surgical procedures applied were cystotomy and capitonnage. The findings of the study showed that pulmonary hydatidosis were located in some segments of the lungs more frequently, primarily in the posterior segment of the lower lobe and the apicoposterior segment of the upper lobe. In addition, the higher prevalence of giant cysts in the lower lobe and their ability to produce symptoms only after being enlarged suggest a role of mechanisms other than elasticity of the lungs. © 2008 Lippincott Williams & Wilkins, Inc.

    Long-term survival after R0 resection of thymoma
    (SAGE Publications Inc., 2018) Koçer B.; Kaplan T.; Günal N.; Koçer B.G.; Akkaş Y.; Yazkan R.; Han S.
    Background: The aim of this study was to evaluate the results of R0 resection of thymoma to identify prognostic factors for long-term outcomes. Methods: Data of 62 patients (28 male, 34 female) with a mean age of 47.26 ± 14.42 years, who underwent R0 resection for thymoma and were followed-up between February 2004 and March 2016, were analyzed retrospectively. Results: Eight patients had a video-assisted thoracoscopic thymectomy and 54 had a transsternal extended thymectomy. During a mean follow-up of 128.67 ± 7.95 months, regional recurrence of thymoma was observed in 9 (14.5%) patients. Overall 5- and 10-year survival rates were 85.36% and 78.20%, respectively. The 5- and 10-year survival rates in patients aged < 50 years were significantly better than in those aged ? 50 years (92% and 72% vs. 88% and 39%, p < 0.0001). The 10-year overall survival of patients in Masaoka stage I and II was better than those in stage III (88.9%, 78.4%, 69.8%, respectively, log-rank p < 0.001). The 10-year survival of patients with World Health Organization histological type A, AB, and B1 thymomas was better than those with type B2 and B3 (log-rank test p < 0.001). In multivariate analysis, age < 50 years (p = 0.001), Masaoka stage (p = 0.006), histological type (p = 0.001), and recurrence (p = 0.04) were independent prognostic factors for survival. Conclusion: Our study indicates that age < 50 years, Masaoka stage, histological type, and recurrence are the determinants of survival in surgically resected cases of thymoma. © The Author(s) 2018.
