Publication Metadata only Reconstruction of sternal cleft with autologous cartilage graft in an adult(2015-06-01) ERMERAK, NEZİH ONUR; BOSTANCI, KORKUT; YÜKSEL, MUSTAFA; KURU P., ERMERAK N. O., BOSTANCI K., YÜKSEL M.Sternal cleft is a rare chest wall deformity associated with various malformations. Primary closure is the gold standard in the newborn period. Alternative techniques are possible for older patients. A 23-year-old woman with a partial sternal cleft and no additional deformity, underwent reconstruction using costal cartilage grafts. Postoperative physical and functional were excellent.Publication Metadata only Quality of life before and after pulmonary endarterectomy inchronic thromboembolic pulmonary hypertension(2012-06-10) YILDIZELİ, BEDRETTİN; ERMERAK, NEZİH ONUR; BOSTANCI, KORKUT; YILDIZELİ B., ELDEM B., ERMERAK N.

O., ÇETİNKAYA Ç., BOSTANCI K.Publication Open Access Do Nuss bars compromise the blood flow of the internal mammary arteries?(OXFORD UNIV PRESS, 2013-09) YILDIZELİ, BEDRETTİN; Yuksel, Mustafa; Ozalper, Mehmet Hakan; Bostanci, Korkut; Ermerak, Nezih Onur; Cimsit, Cagatay; Tasali, Nuri; Yildizeli, Bedrettin; Batirel, Hasan FevziOBJECTIVES: Minimally invasive repair of pectus excavatum, the so-called Nuss procedure, has become a popular technique in recent years. The internal mammary arteries (IMAs) lie on the posterolateral surface of the sternum, and the Nuss bar is likely to obstruct the blood flow in these arteries. This obstruction could become important in the later stages of the lives of these young people if they were to require coronary artery bypass grafting. The goal of this study is to investigate the extent of obstruction of the IMAs caused by Nuss bars. METHODS: Data were collected prospectively on all patients who underwent the Nuss procedure between October 2011 and May 2012. Patients with a history of pectus excavatum repair by open surgery and those who were younger than 16 years of age were excluded. Computed tomography-angiography (CTA) was performed for the detection of IMA blood flow preoperatively and on the 10th postoperative day. Blood flow in the IMAs was evaluated blindly by two radiologists and classified as blood flow unaffected (group I) or affected (group II) by comparing the assessment of preoperative and postoperative CTAs. The patients in group II were also categorized as having blood flow obstructed bilaterally, blood flow obstructed unilaterally and others (diminished unilaterally/diminished on one side or obstructed on the other side). RESULTS: Thirty-four patients (31 male and three female; mean age 20.7 +/- 4.2 years) underwent surgery. Blood flow was affected in 15 patients (44%), with bilateral obstruction in five, unilateral obstruction in seven, and unilateral diminished flow in two patients. In one patient, blood flow was diminished on one side and obstructed on the other. There was no significant difference between unaffected group I patients and affected group II patients in terms of sex, age, type of deformity, Haller index and the number of bars placed. CONCLUSIONS: Nuss bars cause pressure on the IMAs, but a risk factor for this effect could not be identified. This is a relatively common clinical consequence of minimally invasive repair of pectus excavatum, and the long-term effects will be apparent following bar removal.Publication Metadata only Malign mezotelyoma tedavisinde değişen tedavi trendlerinin sağkalıma etkisi(2014-05-08) LAÇİN, TUNÇ; ERMERAK, NEZİH ONUR; BOSTANCI, KORKUT; YILDIZELİ, BEDRETTİN; LAÇİN T., ERMERAK N. O., BİLGİ Z., ÖMERCİKLİOĞLU H., ÇETİNKAYA Ç., SAYAN B., BOSTANCI K., YILDIZELİ B., YÜKSEL M., BATIREL H. F.Publication Open Access Quality of life of patients who have undergone the minimally invasive repair of pectus carinatum(OXFORD UNIV PRESS INC, 2013-01) BOSTANCI, KORKUT; Bostanci, Korkut; Ozalper, Mehmet Hakan; Eldem, Barkin; Ozyurtkan, Mehmet Oguzhan; Issaka, Adamu; Ermerak, Nezih Onur; Yuksel, MustafaSeveral studies previously demonstrated an improvement in the quality of life (QoL) of the patients undergoing a minimally invasive repair of pectus excavatum, but there are no data about such improvement following the minimally invasive repair of pectus carinatum (PC) deformity. The purpose of this study was to investigate the effects of the minimally invasive repair of PC deformity on the psychosocial and physical functioning of the patients. Among 40 patients who underwent minimally invasive repair for PC deformity from July 2008 to March 2011, 35 patients accepted to answer the QoL questionnaires, and 30 of them who had completed the postoperative 6th month were evaluated in this study. The modified two-step Nuss questionnaire was used for the QoL assessment. All patients and their parents completed the appropriate questionnaires regarding the patients' preoperative psychosocial and physical functioning, and they were asked to answer the same questions on the postoperative 6th month. The results from these questionnaires were analysed using Wilcoxon signed rank test to investigate the effects of the minimally invasive repair of PC deformity on psychosocial and physical functioning of the patients. The questionnaires used in the study confirmed the positive impact of the surgical correction on psychosocial and physical well-being in the patients and their parents. Spearman's rho correlation coefficient determined how well the answers to the same question at two different times correlated with each other, and Cronbach's alpha demonstrated the internal consistency of these answers. These two parameters showed that the statistical results of the study were reliable enough. Statistical analysis of the scoring of the individual questions and the total scoring of individual patients revealed a statistically significant improvement (P < 0.05) following surgery. Similar significant improvements were observed in the total scoring of individual parents and in most scoring of the individual questions (10 of 13, 77%) in the parental questionnaire (P < 0.05). The results of this study confirm for the first time that minimally invasive repair of PC deformity has a positive impact on both psychosocial and physical functioning of the patient, which is supported by parental assessment.Publication Metadata only Bronchoscopic lung volume reduction with coils for end-stage chronic obstructive pulmonary disease: a single institutionexperience(2015-05-31) BOSTANCI, KORKUT; OLGUN YILDIZELİ, ŞEHNAZ; ERMERAK, NEZİH ONUR; ERYÜKSEL, SEMİHA EMEL; BOSTANCI K., BİLGİ Z., ÖMERCİKOĞLU H., OLGUN YILDIZELİ Ş., ÇETİNKAYA Ç., ERMERAK N.

Perioperative complications may pose difficulty during the subsequent bar removal due to adhesions and tissue plane disruptions during the initial surgery and repair. This report describes bar removal experience in patients whose Nuss procedures were complicated by cardiac injury, pericardial breach, and lung parenchyma/diaphragm injury during the initial procedure. Methods A total of 529 patients who underwent Nuss procedure between 2007 and 2014 were recorded in a prospective database. Twenty patients with complications (cardiac injury [n = 1], pericardial breach [n = 3], and lung parenchyma/diaphragm injury [n = 16]) were identified. All bars were removed via subcutaneous tissue dissection, without intrathoracic visualization. Results Average duration of bars was 36 months (+/- 16 months). All bar removal procedures were completed without any need for extra interventions with negligible blood loss. Eighteen patients were able to be discharged within 2 postoperative days. Conclusion Blind bar removal in patients with previously complicated Nuss procedure seems safe and no other interventions (videothoracoscopy, subxiphoid incision, etc.) during bar removal seem to be necessary.
