Öğe A 5 Year-Old Case with Intratoracic Ganglioneuroma(DERMAN MEDICAL PUBL, 2015) Oncel, Murat; Sunam, Guven Sadi; Yildiran, HuseyinNeurogenic tumors located intrathoracic are rarely seen in childhood. These tumorn can be asymptomatic, also some symptoms may occur due to compression of mass or neurologic and methabolic effects of tumor. Radiologic imaging give information about location and natur of tumor. Completely surgical resection of mass is curative.Öğe Assistant Training Using Videothoracoscopy(ELSEVIER SCIENCE INC, 2016) Oncel, Murat; Sunam, Guven Sadi; Yildiran, Huseyin[Abstract not Available]Öğe Bronchoscopy in Benign Tracheal Stenosis(ELSEVIER SCIENCE INC, 2016) Sunam, Guven Sadi; Oncel, Murat; Yildiran, Huseyin[Abstract not Available]Öğe Dermoid cyst presenting with tachyarrhythmia: a case report(BAYCINAR MEDICAL PUBL-BAYCINAR TIBBI YAYINCILIK, 2013) Oncel, Murat; Calik, Mustafa; Sunam, Guven SadiIn this article, we report a 45-year-old female patient who was admitted with the complaints of cough, dyspnea and palpitation and referred to our clinic from Cardiology Outpatient Clinic due to tachyarrhythmia with a preliminary diagnosis of mediastinal mass. Thoracic computed tomography (CT) showed a smooth, lobulated contour and locally calcified cystic mass with a size of 7x6 cm in the right-sided middle mediastinum showing air-fluid level. The thorax was explorated from the fifth intercostal space with a right posterolateral thoracotomy incision. Exploration revealed a mediastinal mass originating from vena cava superior at the upper part and reaching the lower lobe. The mass was excised. The result of the histopathological examination was reported as a dermoid cyst containing hair, cartilage and sebaceous glands. We present this case as cardiac arrhythmia is a rare sign of mediastinal cysts.Öğe Giant Benign Mediastinal Masses Extending into the Pleural Cavity(THIEME MEDICAL PUBL INC, 2016) Sunam, Guven Sadi; Oncel, Murat; Ceran, Sami; Odev, Kemal; Yildiran, HuseyinIntroduction The aim of the study was to evaluate the results of surgery to remove huge mediastinal masses and their pathology. Surgical resection was chosen for accurate diagnosis and treatment of the huge mediastinal masses extending into the pleural cavity. Methods Records were reviewed for eight patients who had the diagnosis of huge benign mediastinal masses and who underwent operation; details of the patients and operations were recorded. Results Mean age was 34.5 (range 22 to 44) years, and male-to-female ratio was 2:6. Computed tomography and magnetic resonance imaging (MRI) were used to evaluate the location and extent of the abnormality and to characterize the tissue components of the mass. Most of the tumors were located in the posterior mediastinum. The most frequent presenting symptom was exertional dyspnea. The majority of cases underwent posterolateral thoracotomy, and complete resection was possible in seven patients. Partial resection could only be performed in one. The mean diameter of the resected masses was 15 x 10 cm. Histopathologic examination revealed 3 neurogenic tumors, 2 teratomas, 1 thymolipoma, and 1 ectopic thyroid, and 1 hemangioma. Minor complication was seen in two cases. Conclusion The presurgical thoracic MRI provided correct diagnosis along with radiologic characterization and topography. Surgery must be the preferred treatment in huge benign mediastinal masses.Öğe The importance of computed tomography for tracheobronchial foreign body aspiration(CUKUROVA UNIV, FAC MEDICINE, 2016) Sunam, Guven Sadi; Oncel, Murat; Yildiran, Huseyin; Kutahya, Emine Cepni; Gumus, Irem[Abstract not Available]Öğe In suspicion of foreign body aspiration, clinical follow up or radiological follow up?(CUKUROVA UNIV, FAC MEDICINE, 2016) Oncel, Murat; Sunam, Guven Sadi; Yildiran, Huseyin; Ozdemirkan, Aysun; Bozdogan, Serdal[Abstract not Available]Öğe Incidental Transient Cortical Blindness after Lung Resection(THIEME MEDICAL PUBL INC, 2016) Oncel, Murat; Sunam, Guven Sadi; Varoglu, Asuman Orhan; Karabagli, Hakan; Yildiran, HuseyinTransient vision loss after major surgical procedures is a rare clinical complication. The most common etiologies are cardiac, spinal, head, and neck surgeries. There has been no report on vision loss after lung resection. A 65-year-old man was admitted to our clinic with lung cancer. Resection was performed using right upper lobectomy with no complications. Cortical blindness developed 12 hours later in the postoperative period. Results from magnetic resonance imaging and diffusion-weighted investigations were normal. The neurologic examination was normal. The blood glucose level was 92 mg/dL and blood gas analysis showed a PO2 of 82 mmHg. After 24 hours, the patient began to see and could count fingers, and his vision was fully restored within 72 hours after this point. Autonomic dysfunction due to impaired microvascular structures in diabetes mellitus may induce posterior circulation dysfunction, even when the hemodynamic state is normal in the perioperative period. The physician must keep in mind that vision loss may occur after lung resection due to autonomic dysfunction, especially in older patients with diabetes mellitus.Öğe Increased ischemia-modified albumin and malondialdehyde levels in videothoracoscopic surgery(WOLTERS KLUWER MEDKNOW PUBLICATIONS, 2016) Oncel, Muide; Kiyici, Aysel; Oncel, Murat; Sunam, Guven Sadi; Sahin, Emel; Adam, BahattinBACKGROUND: Videothoracoscopic surgery leads to general organ hypoperfusion by reducing mean arterial pressure, systemic vascular resistance, and end-diastolic volume index. Oxidative stress occurs as a result of hypoperfusion. Evaluation of the short-term effects of videothoracoscopic sympathectomy on serum ischemia-modified albumin (IMA), malondialdehyde (MDA), and nitric oxide (NO) levels in patients with primary hyperhidrosis was aimed. METHODS: Twenty-six patients who underwent videothoracoscopic surgery were contributed in this study. Venous blood samples were obtained from these patients 1 h before and after the surgery. IMA, MDA, and NO levels were measured in serum samples by colorimetric methods. Albumin concentrations were also measured for each sample, and albumin-adjusted IMA levels were calculated. RESULTS: Postoperative IMA, albumin-adjusted IMA, and MDA values were significantly higher compared to the preoperative values (P = 0.003, 0.027, 0.018, respectively). However, postoperative NO levels were lower than the preoperative values (P = 0.002). There was no significant difference between pre- and postoperative albumin concentrations, and there was no significant correlation between the parameters tested. CONCLUSIONS: We can conclude that elevation in MDA and IMA levels after videothoracoscopic surgery was caused by increased oxidative stress due to minimal ischemia-reperfusion injury after the infusion of CO 2 during the surgical process. Videothoracoscopic sympathectomy operation causes a decrease in NO production, and this should be taken in consideration when evaluating nitrosative stress in videothoracoscopic surgery.Öğe Intercostal Schwannoma Developed After Radiotherapy: Case Report(2013) Oncel, Murat; Sunam, Guven Sadi; Karabaglı, Pınar; Karabaglı, HakanOlgu 4 yıl önce sol meme kanseri nedeniyle mastektomi yapılmış ve radyoterapi almış idi.

There are many causes of poor closure including infection, pain, weak tissue or muscle at the wound site, injury to the wound area, and other factors. In this article, we describe a novel technique for the closure of thoracotomy. The advantages of our technique are simplicity, speed, effectiveness, and using lesser sutures in closing the thorax.Öğe Management of Chest Tubes for Thoracic Surgery(ELSEVIER SCIENCE INC, 2016) Oncel, Murat; Sunam, Guven Sadi; Yildiran, Huseyin[Abstract not Available]Öğe Multidetector computed tomography and magnetic resonance imaging findings in pulmonary hydatid cysts(2019) Cebeci, Hakan; Ozlu, Mustafa Yasir; Kilincer, Abidin; Uysal, Emine; Durmaz, Mehmet Sedat; Ucar, Ramazan; Sunam, Guven SadiAim: Computed tomography (CT) and magnetic resonance imaging (MRI) are diagnostic modalities in pulmonary hydatid disease.We aimed to present CT and MRI findings in pulmonary hydatid disease.Material and Methods: CT and MRI findings of pulmonary hydatid cysts from January 2011 through June 2018 were evaluatedretrospectively. CT images of 112 patients and MRI images of 27 patients were evaluated. Patients’ gender and ages, lesion numberand distribution, concomitant organ involvement, complications, HU density of lesions on CT and signal characteristics of lesions onMRI were analyzed. T2 hypointense rim, T1 and T2 signal intensity, daughter vesicle and detached membranes were the evaluatedparameters on MRI.Results: 147 hydatid cyst lesions of 119 (66 female, 53 male) patients with a mean age of 39.419.6 years were included in the study62 (52.1%) of patients had isolated lung involvement. 79 of 119 patients (66.4%) had solitary lung lesion. Mean CT density of cystswere 16 HU. 25 of 32 cysts showed T2 hypointense rim on MRI.Conclusion: Imaging plays important role in diagnosis and presurgical evaluation of pulmonary hydatid disease. CT is mostly usedin diagnosis; MRI should be a choice particularly in pediatric population.Öğe Myofibroblastic Tumor Seeming Like Schwannoma(DERMAN MEDICAL PUBL, 2015) Oncel, Murat; Sunam, Guven Sadi; Yildiran, Huseyin; Karabagli, Pinar; Dobur, FatmaMyofibroblastic tumors are rarely seen. Radiological imaging have enough information about tumor, but diagnosis is made with histopathologically. For operable intrathoracic tumors, progression is quite good by surgical resection of tumor. In our case, we performed resection via videothoracoscopy as a safe procedure. For inoperable tumors medical treatments are suggested.Öğe Pain Control With Bupivacaine After Lung Resections(ELSEVIER SCIENCE INC, 2017) Oncel, Murat; Sunam, Guven Sadi; Yildiran, Huseyin[Abstract not Available]Öğe A Sail-like Glass Piece into the Cervical Esophagus(DERMAN MEDICAL PUBL, 2016) Oncel, Murat; Sunam, Guven Sadi; Yildiran, Huseyin[Abstract not Available]Öğe Simultaneous Bilateral Secondary Pneumothorax(MODESTUM LTD, 2015) Oncel, Murat; Sunam, Guven Sadi; Yildiran, HuseyinSimultaneous bilateral pneumothorax is a very rarely condition that is mainly seen in patients with underlying metastatic disease or lung cancer.
