Publication Open Access No Adverse Outcomes of Video-Assisted Thoracoscopic Surgery Resection of cT2 Non-Small Cell Lung Cancer during the Learning Curve Period(2017-08-05) YILDIZELİ, BEDRETTİN; Bilgi, Zeynep; Batırel, Hasan Fevzi; Yıldızeli, Bedrettin; Bostancı, Korkut; Laçin, Tunç; Yüksel, MustafaPublication Open Access Postoperative psychiatric disorders in general thoracic surgery: incidence, risk factors and outcomes(OXFORD UNIV PRESS INC, 2010-05) YILDIZELİ, BEDRETTİN; Ozyurtkan, Mehmet Oguzhan; Yildizeli, Bedrettin; Kuscu, Kemal; Bekiroglu, Nural; Bostanci, Korkut; Batirel, Hasan Fevzi; Yuksel, MustafaObjective: Postoperative psychiatric disorders (PPDs) may complicate the post-surgical outcome. We analysed the types, incidences, risk factors and outcomes of the PPDs in non-cardiac thoracic surgery patients. Methods: All patients (n = 100) undergoing major non-cardiac thoracic surgery from January 2004 to March 2005 were investigated prospectively. The diagnosis of PPD was made based on the Diagnosis and Statistical Manual of Mental Disorders. The patients were grouped into two according to the presence (group I) or absence (group II) of PPD. Data on pre-, per- and postoperative factors, and the adverse outcomes were analysed. Results: Eighteen patients (18%) developed PPD, including delirium in 44%, adjustment disorders in 22%, panic attack in 17%, minor depression in 11% and psychosis in 6%. The patients who developed PPD were older (58 +/- 17 vs 50 +/- 15 years, p = 0.05), had a longer operation time (6 +/- 1 vs 5 +/- 2 h, p = 0.015) and hospital stay (13 +/- 9 vs 8 +/- 5 days, p = 0.019). The morbidity and mortality rates were not significantly different between the groups (67% vs 46%; 11% vs 1%, respectively). The causative factors in the development of PPD were older age, longer operation time, abnormal serum chemistry values of sodium, potassium, calcium and glucose, hypoalbuminaemia, the presence of the postoperative respiratory distress and infection and blood transfusion (p < 0.05). Conclusions: PPDs are associated with adverse outcomes including a longer hospital stay, and increased morbidity and mortality rates. The identification, detection and elimination of these risk factors are recommended. (C) 2009 European Association for Cardio-Thoracic Surgery. Published by Elsevier B.V.

Video-assisted thoracic surgery (VATS) leads to less postoperative pain compared with thoracotomy. In this study, we analyzed pain scores in patients who underwent lung resections with VATS or thoracotomy. Patients and Methods: Patients who underwent lung resections with uniportal, biportal VATS or thoracotomy between May 2015 - May 2017 were included in the study. Visual Analogue Scale (VAS) pain scores were recorded on postoperative day 1, 5 (or at discharge), 2nd week, 1st and 3rd months. Patients were classified in 3 groups, uniportal VATS (n=178), biportal VATS (n=15), thoracotomy (n=60). Demographics, resection type, mortality, morbidity and epidural catheter use were recorded. Results: Two hundred and fifty-three patients (average age was 57.3 +/- 12.7, 94 females) were included in the study. Median hospital stay was 5 days. Uniportal and biportal groups had significantly lower pain scores in all intervals compared with thoracotomy. No chronic pain was seen in VATS groups. Uniportal and biportal groups had similar pain scores at all times. Epidural use or size of specimen did not affect pain in VATS patients (p=0.18 vs p=0.68). Conclusion: Video-assisted thoracic surgery decreases the need for epidural patient control analgesia. Specimen size does not affect postoperative pain and chronic pain is rare.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.

F.Publication Open Access Effect of the amount of intraoperative fluid administration on postoperative pulmonary complications following anatomic lung resections(MOSBY-ELSEVIER, 2015-01) KARARMAZ, ALPER; Arslantas, Mustafa Kemal; Kara, Hasan Volkan; Tuncer, Beliz Bilgili; Yildizeli, Bedrettin; Yuksel, Mustafa; Bostanci, Korkut; Bekiroglu, Nural; Kararmaz, Alper; Cinel, Ismail; Batirel, Hasan F.Objective: Excessive fluid administration during lung resections is a risk for pulmonary injury. We analyzed the effect of intraoperative fluids on postoperative pulmonary complications (PCs). Methods: Patients who underwent anatomic pulmonary resections during 2012 to 2013 were included. Age, weight, pulmonary function data, smoking (pack-years), the infusion rate and the total amount of intraoperative fluids (including crystalloid, colloid, and blood products), duration of anesthesia, hospital stay, PCs, and mortality were recorded. PCs were defined as acute respiratory distress syndrome, need for intubation, bronchoscopy, atelectasis, pneumonia, prolonged air leak, and failure to expand. Univariate analyses and multivariate logistic regression were performed. A Lowess curve was drawn for intraoperative fluid threshold. Results: In 139 patients, types of resections were segmentectomy-lobectomy (n = 69; extended n = 37; video-assisted thoracoscopic surgery n = 19) and pneumonectomy (n = 9; extended n = 5). One hundred sixty-one PCs were observed in 76 patients (acute respiratory distress syndrome [n = 5], need for intubation [n = 9], atelectasis [n = 60], need for bronchoscopy [n = 19], pneumonia [n = 26], prolonged air leak [n = 19], and failure to expand [n = 23]). Overall mortality was 4.3% (6 out of 139 patients). Mean hospital stay was 8.5 +/- 4.8 days. Univariate analyses showed that smoking, intraoperative total amount of fluids, crystalloids, blood products, and infusion rate as well as total amount of crystalloids and infusion rate during the postoperative first 48 hours were significant for PCs (P = .033, P < .0001, P = .001, P = .03, P < .0001, P = .002, and P < .0001, respectively). In multivariate logistic regression analysis intraoperative infusion rate (P < .0001) and smoking were significant (P = .023). An infusion rate of 6 mL/kg/h was found to be the threshold. Conclusions: The occurrence of postoperative PCs is seen more frequently if the intraoperative infusion rate of fluids exceeds 6 mL/kg/h.Publication Metadata only Resection of synchronous ipsilateral giant bullae and bronchial carcinoid tumor(BAYCINAR MEDICAL PUBL-BAYCINAR TIBBI YAYINCILIK, 2013) YILDIZELİ, BEDRETTİN; Issaka, Adamu; Bostanci, Korkut; Yildizeli, Bedrettin; Yuksel, Mustafa; Batirel, Hasan F.Synchronous bronchial carcinoid tumor and giant bullae are rare entities. In this article, we report a 62-year-old male presenting with dyspnea, cough and chest pain. No improvement was achieved with medical treatment. Examinations revealed right lower lobe endobronchial carcinoid tumor and upper lobe giant bullae. Simultaneous bullectomy and bronchotomy and carcinoid tumor resection through right thoracotomy, as well as postoperative tracheostomy were performed. The patient who had 2 lt/minute oxygen was discharged on the 16th postoperative day without any complication. Radiological, apprearance, clinical situation and pulmonary functions were improved and better quality of life was observed at six months after surgery. Forced expiratory volume in 1 second (FEV1) increased from 0.90 liter (29% predicted) to 1.13 liter (37% predicted). Patient continued to smoke and died due to cor pulmonale one year after discharge.
