The reliability of mediastinoscopic frozen sections in deciding on oncological surgery in bronchogenic carcinoma

IntroductionThis study was carried out to determine the accuracy of mediastinoscopic frozen section examination, performed prior to major surgery-especially where mediastinal lymph node metastasis (N2 disease) was suspected. We aimed to find out whether or not mediastinoscopic frozen section analysis was (i) a reliable tool when deciding to continue resection in lung cancer patients and (ii) reliable in diagnosing mediastinal masses.MethodsOne-hundred and thirty-six patients undergoing mediastinoscopy were enrolled in this study. Resection was planned for each case, and biopsies were taken from at least two sites, including the subcarinal lymph node. Thoracotomy and resection were performed when the results of frozen section examination were negative for malignancy in patients with lung cancer. Results of frozen section examination during mediastinoscopy were compared to the results of definitive histological examination of the same specimens stained using haematoxylin-eosin. Additionally, the results of frozen section examination were compared to the results of definitive histological examination of the lymph nodes excised during resection.ResultsWe determined total sensitivity, specificity, positive predictive and negative predictive values of 94.51%, 100%, 100% and 90%, respectively. In the 105 patients with malignant diseases, these values were 93.33%, 100%, 100% and 91.84%, respectively. In the 31 patients with benign diseases, values were 96.77%, 100%, 100% and 100%, respectively.ConclusionsIt was confirmed that mediastinoscopy supported by frozen section examination plays an important role in establishing diagnosis and planning treatment both in benign and malignant diseases.

Radiological Findings and Outcomes of Bronchial Artery Embolization in Cryptogenic Hemoptysis

Management of cryptogenic massive hemoptysis is difficult, and conservative treatment may be inadequate to stop the hemorrhage. Surgery is not a reasonable option because there is no underlying identifiable pathology. This study aimed to investigate the radiologic findings and bronchial artery embolization outcomes in cryptogenic hemoptysis, and to compare the results with non-cryptogenic hemoptysis. We evaluated 26 patients with cryptogenic hemoptysis and 152 patients with non-cryptogenic hemoptysis. A comparison of the bronchial artery abnormalities between the cryptogenic and non-cryptogenic hemoptysis groups showed that only extravasation was more statistically significant in the cryptogenic hemoptysis group than in the non-cryptogenic hemoptysis group, while the other bronchial artery abnormalities, such as bronchial artery dilatation, hypervascularity, and bronchial-to-pulmonary shunting, showed no significant difference between groups. Involvement of the non-bronchial systemic artery was significantly greater in the non-cryptogenic hemoptysis group than in the cryptogenic hemoptysis group. While 69.2% of patients with cryptogenic hemoptysis also had hypervascularity in the contralateral bronchial arteries and/or ipsilateral bronchial artery branches other than the bleeding lobar branches, this finding was not detected in non-cryptogenic hemoptysis. Embolization was performed on all patients using polyvinyl alcohol particles of 355-500 µm. Hemoptysis ceased in all patients immediately after embolization. While recurrence of hemoptysis showed no statistically significant difference between the cryptogenic and non-cryptogenic hemoptysis groups, it was mild in cryptogenic hemoptysis in contrast to mostly severe in non-cryptogenic hemoptysis. Transarterial embolization is a safe and effective technique to manage cryptogenic hemoptysis.

A rare tumor: tracheal Ewing's sarcoma.

A 70-year-old man, with renal failure, applied with the complaint of shortness of breath. Thoracic computed tomography revealed dense intraluminal fields at distal trachea. The bronchoscopy revealed a solid mass, located on the lateral wall of the trachea (Fig. 1). During bronchoscopy, an endobronchial mass excision with laser was performed. The immunohistochemical examination revealed that the tumor cells reacted positively to vimentin and friend leukemia integration (FLI)-1, and negatively to desmin, CD31, S-100, and pancytokeratin (Figs. 2 and 3). The findings were consistent with ES. Due to the suspicions concerning the surgical margin, radiotherapy (RT) was recommended. Postoperatively, 50.4-Gy RT was applied. Metastatic lesions in the scalp and humerus were revealed 3 months after the RT. Chemotherapy could not be performed because of the renal insufficiency. The patient died 8 months after surgery due to renal failure.

Two-piece cryopreserved tracheal allotransplantation: an experimental study.

OBJECTIVES For successful reconstruction with tracheal allotransplants following long tracheal resections, problems related to the preservation and vascularisation of the tracheal graft have to be solved. In this study, instead of using a long-segment single-piece graft, we used a graft that has been split into two. The aim was to use this graft after cryopreservation in order to ease neo-vascularisation and to maintain tracheal integrity by transplanting it to two separate regions of the dog cervical trachea. METHODS This experimental study was conducted in animal laboratories of the medical school on 11 half-blood dogs. The trachea obtained from the first dog was 8 cm in length; it was split into two pieces of 4 cm each and stored in the preservation solution at -80 degrees C for 4 weeks. Following this, the dog was sacrificed. Two 2 cm portions of cervical trachea were excised from the second dog. These parts were then reconstructed with two tracheal grafts of the same length as the cryopreserved ones. Ten dogs that were grouped into five groups of two dogs each underwent the same procedure. The subjects had a bronchoscopic evaluation on the third postoperative week. Anastomosis regions of the test tracheas were resected to be examined histopathologically. RESULTS Seven subjects were found to have third-degree obstructions during bronchoscopy; two had close to fourth-degree obstructions. In the histopathological examination, contrary to the findings of the bronchoscopies, 75% of the anastomoses had intact epithelium. The cartilage was seen to have well-preserved structural characteristics in all the anastomoses. Twelve anastomoses had moderate, seven mild and one had severe inflammation. All anastomoses had either good or very good level of vascularisation. CONCLUSIONS The integrity of the tracheal epithelium can be maintained with cryopreservation and split anastomosis technique. The cartilage preserves its structural characteristics despite losing its viability, thereby offering an advantage to maintain airway patency.

Tracheobronchomalacia as a Rare Cause of Chronic Dyspnea in Adults

Objective: To emphasize the importance of a careful clinical evaluation to prevent unnecessary interventions and treatments. Clinical Presentation and Intervention: A 76-year-old female patient had been diagnosed with asthma during previous admissions to different hospitals. She had also undergone fiberoptic bronchoscopy (FOB) on 2 occasions for evaluation of right middle lobe atelectasis observed on computed tomography. A repeated FOB revealed tracheobronchomalacia and nodular bronchial amyloidosis. A silicone Y stent was inserted, but the dyspnea increased. Excessive granulation tissue developed, and the patient died despite ventilatory support. Conclusion: The stenting technique used did not prevent the development of respiratory failure and death in this patient. Hence, a surgical procedure could be considered as an alternative to stenting in such cases.

A rare complication of blunt trauma; diaphragm-pericardium rupture and cardiac herniation in a child case

Diaphragma and pericardium rupture is rarely seen after blunt trauma. Its treatment is surgery. A 4-year-old male patient who was operated for diaphragm and pericardium rupture which developed after blunt trauma; rarity of this union, differences in the clinical and radiological features in children was examined.

Pneumomediastinum after retching

A 25-year-old woman with hirsutism presented to the Emergency Department of the medicine faculty in Gaziantep University with a 4-h History of dyspnoea, dysphagia, coughing, continuous and progressive chest pain radiating to the back and palpation of her neck. The physical examination was significant for diffuse neck and chest subcutaneous emphysema. The x-ray study and CT scan of the chest revealed pneumomediastinum. The patient reported that 6 h before presentation she took spironolactone due to hirsutism and she retched. Retching caused the symptoms. The patient was followed conservatively and fully recovered over the next 7 days. Spontaneous pneumomediastinum developed in this patient with no underlying lung disease, presumably from air leakage secondary to the excessive elevation of intrathoracic pressure due to retching. Pneumomediastinum is an uncommon disease arising most frequently and remains largely underdiagnosed clinically, especially in young, healthy patients.

Successful repair in a child with traumatic complex bronchial rupture

Tracheobronchial ruptures (TBR) are dramatic injuries, rarely observed in children, that can have fatal consequences, even threatening life. Etiologically, especially high-impact blunt trauma, penetrating trauma with perforating/penetrating instruments or firearms and iatrogenic injuries may result in TBR. These can be difficult to diagnose in emergency room conditions and the diagnosis may be delayed. Delay in the diagnosis causes acute or delayed complications. Treatment methods change depending on the type of the injury, its localization and comorbid pathologies. By presenting this case from our clinic with fragmented bronchial rupture due to a blunt trauma, we aimed to point out the maneuvers during the operation together with treatment methods and their results.

A new method in thoracoscopic inferior mediastinal lymph node biopsy: a case report

IntroductionWe performed video-thoracoscopy with a video-mediastinoscope to conduct a mediastinal lymph node biopsy. Here, we discuss the various advantages of the method.Case presentationA 56-year-old Turkish Caucasian man had been complaining of dyspnea on exertion, hacking cough, fever and continuous sweating for one and a half months. Thoracic computed tomography revealed enlarged paratracheal and aorticopulmonary lymph nodes, the largest of which was 1 cm in diameter and reticulo-micronodular interstitial infiltration extending symmetrically to the pleural surfaces in both pulmonary perihilar areas. Computed tomography supported positron emission tomography showed increased fluorodeoxyglucose retention in lymph nodes in both hilar areas (10R and 10L) (maximum standardized uptake values 5.6 and 5.7), and in the right lower paratracheal (4R) (maximum standardized uptake value 4.1) and right para-esophageal (8) (maximum standardized uptake value 8.9) lymph nodes. Pathological examination of the right lymph node number 8 biopsy using the video-mediastinoscope revealed the presence of granulomatous inflammation. No problems were observed during the postoperative period.ConclusionThe use of the video-mediastinoscope for inferior lymph node biopsy in thoracoscopy is an easy, safe and practical method, especially in patients with pleural adhesions.

Resection via Median Sternotomy in Patients with Lung Cancer Invading the Main Pulmonary Artery

Abstract Background: Conventional pneumonectomy via posterolateral thoracotomy is not always possible in cases with T4 tumour with widespread pulmonary artery invasion. Our objective is to present our surgical experiments in cases with a hilar mass who were thought to have pulmonary artery invasion, in whom we performed intrapericardial pneumonectomy through median sternotomy. Method: Nine cases who had undergone intrapericardial pneumonectomy via median sternotomy were included in this study and evaluated retrospectively. These cases were thought to have right or left pulmonary artery invasion in preoperative evaluation. Results: Two cases had right and seven cases left pneumonectomy. Based on TNM classification, two patients were Stage IIB, two Stage IIIA and five Stage IIIB in postoperative histopathological examination. Either right or left main pulmonary artery invasion was seen in IIIB cases while invasion was limited to the pericardium in the others. Lymph node involvement was detected in seven cases while six cases were N1, and one case was N2. There was no operative mortality. Conclusion: Standard posterolateral thoracotomy might not be possible in all cases, particularly in patients with hilar tumours invading the main pulmonary artery. In such patients an intrapericardial approach with median sternotomy provides an easier and safer alternative while making it possible to have wider lymph node dissection. Furthermore, if necessary, hemi-clamshell incision can easily be added to this approach.
