    Introduction: Thymectomy is the preferred standard treatment in younger non-thymoma patients with myasthenia gravis as well as in patients with early stage thymoma. Total thymectomy by median sternotomy has been the surgical approach since resection of the thymus with video-assisted thoracoscopic surgery (VATS). Aim: To compare the clinical outcomes of VATS thymectomy with conventional open thymectomy for neoplastic and non-neoplastic thymic diseases. Material and methods: Forty patients underwent thymectomy between October 2012 and January 2016. Fifteen patients were male and 25 patients were female. The mean age was 40.3 +/- 17.7 years. Seventeen (55\%) patients underwent VATS thymectomy and 23 (45\%) patients underwent an open procedure. We retrospectively reviewed the data of the patients and compared these two techniques. Results: The mean tumor size was 5.17 +/- 3.2 cm in the thymoma group (VATS 2.5 +/- 2.4 cm vs. open access 4.7 +/- 3.7 cm). None of the patients experienced a myasthenic crisis. Conversion to thoracotomy was required in 1 patient in the VATS group due to bleeding from the right internal mammary artery

    Rebound thymic hyperplasia after bone marrow transplantation in children with haemato-oncological diseases
    (TERMEDIA PUBLISHING HOUSE LTD, 2018-01-01) Arpaci, Taner; Karagun, Barbaros Sahin
    Aim of the study: To evaluate prevalence of rebound thymic hyperplasia (RTH) after bone marrow transplantation (BMT) in paediatric patients with haemato-oncological diseases. Material and methods: Between February 2013 and December 2017, BMT was performed in 189 paediatric patients with haemato-oncological diseases in our institution. Fifty-six patients who underwent at least two chest computed tomography (CT) exams performed before and after BMT were included in the study. Maximum transverse and anterior-posterior (AP) diameters and CT attenuation of the thymus were measured on axial images. Thymic enlargement was considered when both transverse and AP diameters increased. RTH was defined as the presence of thymic enlargement on CT after BMT relative to the CT taken before. Results: Twenty of 56 patients (36\%) demonstrated RTH (12 boys, 8 girls
