EBUS ROSE-guided cytological evaluations of intrathoracic lesions. Assessments of the pathological material adequacy and the diagnostic efficacy.

BACKGROUND: Several clinical groups consider cytological assessment under EBUS (Endobronchial Ultrasonography)-ROSE (Rapid Onsite Evaluation) as the golden standard for diagnosis and staging of intrathoracic lesions. On the other hand, some investigators proposed that EBUS-TBNA (Transbronchial Needle Aspiration) has considerably high false-negative rates for diagnosis. In this study, we analyzed our patient cohort (n = 152) with intrathoracic lesions and suspected malignancies evaluated by EBUS-ROSE. Our specific aims were: (i) to determine whether EBUS-ROSE could provide sufficient pathologic material for diagnosis and staging; (ii) to determine the fidelity of EBUS-ROSE-guided initial diagnoses in comparison to paraffin block diagnoses; (iii) to evaluate whether anatomical localization of sampled lymph nodes associate with material adequacy and final diagnoses. METHODS: NCSS (Number Cruncher Statistical System) 2020 Statistical Software (Utah, USA) was used for statistical analysis. RESULTS: In EBUS-ROSE cytological assessment, material adequacy was determined in 50,7% (n = 77) of the cases. Considering the paraffin block pathology as the golden standart, the sensitivity, specificity, positive predictive value, negative predictive value and accuracy rates of EBUS-ROSE were 90,2%, 93,1%, 94,8%, 87,1%, and 91,4%, respectively. There was no statistically significant difference between the final pathology and EBUS cytology results (p > .05) with a non-random Kappa agreement rate as 82.9%. There were differences in material adequacy and diagnoses according to the localization of sampled lymph node stations. CONCLUSIONS: EBUS-ROSE is efficient to decide for the adequacy of the pathological specimen and provides diagnoses with reliable fidelity.

Could cytology supplant frozen section for intraoperative evaluation of thoracic lesions? A single institutional experience in a developing country.

BACKGROUND: The diagnostic performance of cytology was compared with the frozen results and its usability was evaluated as a rapid diagnosis method in intraoperative thoracic surgery in a single institution (Istanbul, Turkey). METHODS: All 197 subsequent patient specimens (cases) from 158 patients who were sent to our department from the thoracic surgery clinic for an intraoperative diagnosis request between the years 2016 and 2021 were evaluated. Obtained results from frozen and cytology were compared with final paraffin section diagnoses. Lesions were grouped into three different groups as nonneoplastic, benign, and malignant neoplasms. RESULTS: Diagnostic accuracy values of cytology and frozen sections in intraoperative consultation were 98.8% and 99.4%, respectively. Sensitivity values of cytology and frozen sections in intraoperative consultation were 96.3% and 98.7%, respectively. Specificity values of cytology and frozen sections in intraoperative consultation were 100% and 100%, respectively. Negative predictive values of cytology and frozen sections in intraoperative consultation were 96.7% and 98.9%, respectively. Positive predictive values of cytology and frozen sections in intraoperative consultation were 100% and 100%, respectively. Kappa statistics between cytology and frozen revealed a very high interrater reliability (Cohen's Kappa value: 0.911; p = .001; p < .01). The difficulty in distinguishing primary and metastatic carcinoma, which is mostly undecided in frozen sections and the definitive diagnosis is left to paraffin sections, seems also be a problem in the cytological examination. CONCLUSIONS: Cytological diagnosis can be used in the evaluation of small biopsy specimens that require tissue preservation in intraoperative consultation, especially for immunohistochemical and advanced genetic studies.

Delayed chest closure for oversized lung allograft in lung transplantation: a retrospective analysis from turkey

Abstract Introduction: The aim of this study was to evaluate the delayed chest closure (DCC) results in patients who underwent lung transplantation. Methods: Sixty patients were evaluated retrospectively. Only bilateral lung transplantations and DCC for oversized lung allograft (OLA) were included in the study. Six patients who underwent single lung transplantation, four patients who underwent lobar transplantation, two patients who underwent retransplantation, and four patients who underwent DCC due to bleeding risk were excluded from the study. Forty-four patients were divided into groups as primary chest closure (PCC) (n=28) and DCC (n=16). Demographics, donor characteristics, and operative features and outcomes of the patients were compared. Results: The mean age was 44.5 years. There was no significant difference between the demographics of the groups (P>0.05). The donor/recipient predicted total lung capacity ratio was significantly higher in the DCC group than in the PCC group (1.06 vs. 0.96, P=0.008). Extubation time (4.3 vs. 3.1 days, P=0.002) and intensive care unit length of stay (7.6 vs. 5.2 days, P=0.016) were significantly higher in the DCC group than in the PCC group. In the DCC group, postoperative wound infection was significantly higher than in the PCC group (18.6% vs. 0%, P=0.19). Median survival was 14 months in all patients and there was no significant difference in survival between the groups (16 vs. 13 months, P=0.300). Conclusion: DCC is a safe and effective method for the management of OLA in lung transplantation.

Intracardiac and pulmonary artery hydatidosis causing thromboembolic pulmonary hypertension.

Hydatidosis is a serious parasitic infection in endemic areas. A rare presentation is pulmonary arterial cysts causing thromboembolic pulmonary hypertension. We report the case of a young man who presented with clinical and radiological findings of thromboembolic pulmonary hypertension. The patient was found to have hydatid cysts in both pulmonary arteries and in the right ventricular outflow tract. To remove all cysts without causing rupture, anaphylactic shock or systemic emboli, placing the patient under cardiopulmonary arrest was necessary, and in the case of pulmonary arterial involvement, total circulatory arrest was necessary. The cysts were removed successfully, and the patient survived the operation. The patient is being followed up on albendazole treatment. Myocardial preservation and management of total circulatory arrest are the cornerstones of a successful surgical outcome.

Extended left pneumonectomy and left atrial reconstruction with autogenous graft in patient with T4 lung cancer.

In selective patients with T4 non-small cell lung cancer with the primary tumor invading the mediastinal organs, extended lung resection may contribute to long-term survival. Adequate patients should be given a chance for surgery if complete resection and required reconstruction can be achieved. In this article, we report a 63-year-old male patient with T4 non-small cell lung cancer invading the left atrium. In the patient, we performed an extended left pneumonectomy with en bloc partial resection of the left atrium wall (4×2.5 cm) where the defect was repaired with pericardial patch via cardiopulmonary bypass. No severe complication developed postoperatively. The patient who was given adjuvant chemotherapy has been living for more than 10 years without disease.

The effect of myasthenia gravis as a prognostic factor in thymoma treatment.

OBJECTIVE: Thymoma is a standard epithelial tumor. Though it is rare, it constitutes 50% of anterior mediastinal masses. Variety of immunological diseases may accompany thymoma; however, myasthenia gravis (MG) is the most frequently associated paraneoplastic syndrome. Most effective treatment for thymoma is complete surgical resection. In this study, impact of MG on prognosis of thymoma cases was examined. METHODS: Records of 61 patients who underwent surgery with diagnosis of thymoma between January 2003 and September 2016 were retrospectively reviewed. All cases were analyzed for data related to age, gender, complaint, localization of lesion, surgical procedure, histopathological diagnosis, stage, MG, and long-term follow-up results. RESULTS: Total of 58 cases were included in the study. Of those, 37 patients were male and 21 were female. Mean age was 48 years. While 24 cases of thymoma were accompanied by MG, 34 cases were not. Duration of follow-up ranged from 1 month to 155 months. CONCLUSION: It was found that in group with MG, 5-year survival rate was 87.5% while it was 82.4% in group without MG. Despite longer duration of survival in group of thymoma associated with MG, there was no significant statistical difference between groups (p=0.311).

Thoracic Traumas: A Single-Center Experience.

OBJECTIVES: Trauma is currently among the most important health problems resulting in mortality. Approximately 25% of trauma-related deaths are associated with thoracic trauma. In the present study, morbidity and mortality rates and interventions performed in patients who had been treated as inpatients in Dr. Siyami Ersek Thoracic and Cardiovascular Surgery hospital after trauma were aimed to be evaluated. MATERIAL AND METHODS: In our study, 404 patients who were treated as inpatients because of thoracic trauma between January 2005 and December 2008 were retrospectively evaluated. RESULTS: The rates of blunt and penetrating trauma were 39.6% and 60.4%, respectively. In the study, 115 (28.4%) patients were noted to have pneumothorax, 99 (24.5%) had hemothorax, and 57 (14.1%) had hemopneumothorax. While tube thoracostomy was sufficient for treatment in approximately 80% of the patients, major surgical interventions were performed in 12.6% of the patients. Mortality rate was found to be 2.2%. CONCLUSION: In patients with chest trauma, necessary interventions should be started at the time of the event, and the time from trauma to arriving at the emergency department should be made the best of. Mortality and morbidity rates in thoracic trauma cases may be reduced by timely interventions and effective intensive care monitoring.

Sympathectomy versus Sympathicotomy in Palmar Hyperhidrosis Comparing T3 Ablation.

OBJECTIVE: The objective of this study was to evaluate and compare thoracoscopic sympathectomy and sympathicotomy at the third ganglia (T3) level for the treatment of primary palmar hyperhidrosis in terms of initial surgery results, complications, and patient satisfaction. MATERIALS AND METHODS: Two groups of patient underwent T3 thoracoscopic sympathectomy and thoracoscopic sympathicotomy under general anesthesia using single-lung ventilation via a double-lumen endotracheal tube by the same surgical team for the treatment of severe primary palmar hyperhidrosis or a combination of levels for multiarea between 2008 and 2013. The groups were homogeneous for relevant demographic, physiological, and clinical data. All patients were examined preoperatively and were followed up at 6 months postoperatively. In both groups, patient's satisfaction was evaluated 6 months after surgery by a detailed interview and scored into three grades (1 = very satisfied, 2 = satisfied, and 3 = dissatisfied). RESULTS: No operative mortality, major intraoperative complication, infections, and Horner syndrome were recorded. There was no treatment failure. The average time of operation was 50 minutes for Group A (sympathectomy) and 36 minutes for Group B (sympathicotomy). Compensatory sweating occurred in 40 patients (89% for Group A and 85.11% for Group B) with a different accumulation of the severity degree. The satisfaction rate was 91.11% for Group A and 93.61% for Group B. CONCLUSION: There was no significant difference between thoracoscopic sympathectomy and sympathicotomy at the third ganglia (T3) level for the treatment of primary palmar hyperhidrosis in terms of initial surgery results, complications, and patient satisfaction. Neither surgical technique is better than the other one for palmar hyperhidrosis treatment. Development of severe compensatory sweating and postoperative pain are major determinant factors of patient dissatisfaction. Sympathicotomy should be preferred for palmar hyperhidrosis treatment, as it is much technically shorter, simpler to implement, and also easier to learn.

Echocardiographic assessment of right ventricular function before and after surgery in patients with pectus excavatum and right ventricular compression.

BACKGROUND: We aimed to evaluate the effect of surgical repair on right ventricular (RV) function in patients with pectus excavatum (PE) and RV compression by Doppler echocardiography. MATERIALS AND METHODS: Twenty-three patients who were admitted to our hospital for surgical correction of PE between 2009 and 2012 were included in the study. After transthoracic echocardiographic evaluation, 16 patients with RV compression were enrolled. All patients were males (100%) with a mean age of 20.5 ± 5.6 years. Transthoracic echocardiography was repeated 1 month after surgery. Echocardiographic evaluation included the assessment of RV diastolic diameter, tricuspid annular plane systolic excursion (TAPSE), pulsed tissue Doppler systolic velocity (S'), RV isovolumic acceleration (RV IVA), systolic pulmonary artery pressure, left ventricular (LV) ejection fraction, and myocardial performance indexes of both the right and the left ventricles (Tei index). RESULTS: Following the surgery, the RV end-diastolic diameter, TAPSE, S', and RV IVA were found to be significantly increased in patients with PE. In addition, RV and LV Tei index significantly improved after surgical correction. CONCLUSIONS: RV function significantly improved after corrective surgery. Quantitative echocardiographic examination provides accurate estimation when deciding for corrective surgery and also should be used in the assessment of postoperative improvement.

Intrathoracic giant solitary fibrous tumor.

BACKGROUND: Solitary fibrous tumor of the pleura is a rare, usually benign, and slow-growing neoplasm. Complete surgical resection for giant tumor of the pleura is challenging because of poor exposure and a large blood supply. We report the case of a giant hypervascular fibrous tumor that filled nearly the entire left hemithorax and anterior mediastinum, and its preoperative management. CASE REPORT: A 59-year-old woman presented to us with exertional dyspnea and chest pain. A chest radiograph showed the right hemithorax completely opaque and a mediastinal shift to the left hemithorax. A tomography scan of the thorax showed a giant mass that almost completely filled the right hemithorax and compressed the mediastinum to the left. Because of excessive bleeding during dissection, the operation was terminated after a biopsy specimen was obtained. The biopsy was diagnosed as a benign fibrous tumour. A thoracic computed tomography angiogram showed that the mass was supplied by multiple intercostal arteries as well as an aberrant artery that branches off the celiac trunk in the subdiaphragmatic region. Due to the many arteries that needed to be embolized, the final decision was to control the bleeding following resection by inducing total circulatory arrest with the help of cardiopulmonary bypass. The bleeding could not be controlled under cardiopulmonary bypass and the patient's death was confirmed. CONCLUSIONS: We report this case to emphasize the necessity of preoperative embolization; the use of cardiopulmonary bypass and total circulatory arrest is not a valid alternative method to control the bleeding.

[Esophageal foreign bodies in children and adults: 20 years experience]. / Çocuklarda ve eriskinlerde özofagus yabanci cisimleri: 20 yillik deneyim.

BACKGROUND: Esophageal foreign object ingestion is frequently seen in all ages. Failure to treat can cause serious complications such as esophageal perforation. The aims of this study were to characterize the clinical features related to foreign objects in the esophagus and to analyze the results of commonly used methods for their removal. METHODS: We analyzed 20 years of records from Siyami Ersek Hospital, Istanbul and identified 512 cases of foreign objects enlodged in the esophagus. RESULTS: In pediatric patients, the majority were aged between 2-5 years (34.4%), while in adult patients, the majority were above 55 years (38.7%). Coins were the most common foreign object detected in children (68.8%), whereas meat impaction was most common in adults (87.4%). The most common location of the foreign object was the cervical esophagus in children (78.2%), and the thoracic esophagus in adults (66.4%). In 30.8% of adults, there was esophageal or systemic disease. Objects were removed with a Magill clamp in 48.3% of children. Rigid endoscopy was the main treatment in adult patients. Perforation due to endoscopy developed in three patients. Surgical repair was performed on these patients but all died due to mediastinitis. CONCLUSION: Underlying esophageal or systemic diseases may predispose adults to foreign object ingestion in the esophagus. Improved endoscopic experience and clinical management of thoracic surgeons led to reduced morbidity and mortality in recent years.

Surgical properties and survival of a pericardial window via left minithoracotomy for benign and malignant pericardial tamponade in cancer patients.

BACKGROUND: Surgical drainage is a rapid and effective treatment for pericardial tamponade in cancer patients. We aimed to investigate the effectiveness of pericardial window formation via mini-thoracotomy for treating pericardial tamponade in cancer patients, and to evaluate clinical factors affecting long-term survival. METHODS: Records of 53 cancer patients with pericardial tamponade treated by pericardial window formation between 2002 and 2008 were examined. Five patients were excluded due to insufficient data. Kaplan-Meier and Cox regression analysis were used for analysis. RESULTS: Forty-eight patients (64.7% male), with a mean age of 55.20 ± 12.97 years were included. Patients were followed up until the last control visit or death. There was no surgery-related mortality and the 30-day mortality rate was 8.33%; all died during postoperative hospitalization. Morbidity rate was 18.75%. Symptomatic recurrence rate was 2.08%. Cancer type and nature of the pericardial effusion were the major factors determining long-term survival (P <0.001 and P <0.004, respectively).Overall median survival was 10.41 ± 1.79 months. One- and 2-year survival rates were 45 ± 7% and 18 ± 5%, respectively. CONCLUSION: Pericardial window creation via minithoracotomy was proven to be a safe and effective approach in surgical treatment of pericardial tamponade in cancer patients. Cancer type and nature of pericardial effusion were the main factors affecting long-term survival.

Long-term results of lung decortication in patients with trapped lung secondary to coronary artery bypass grafting.

PURPOSE: To evaluate long-term results of decortications in patients with symptomatic restrictive pleurisy and trapped lung after coronary bypass grafting. METHODS: Twenty consecutive patients undergoing lung decortications for trapped lung after coronary bypass grafting were prospectively evaluated. Pulmonary function tests were used as objective criteria, and quality of life was assessed by the Medical Research Council dyspnea scale. A p value <0.05 was considered significant. RESULTS: Twenty patients, 3 women and 17 men, with a median age of 59 years were evaluated. The median time interval between coronary bypass grafting and decortications was 9.3 months. The mean preoperative forced expiratory volume in one second and forced vital capacity were 63.8% ± 7.4% and 50.5% ± 6.6% of the predicted value, respectively, and the improvement rates after decortications were 14.97% ± 6.3% and 17.62% ± 6.38%, respectively. Dyspnea scores improved after decortications (p <0.05). The median follow-up was 25 months. After surgery, 3 patients developed superficial wound infections, and out of 7 patients with prolonged air leaks, 2 underwent re-operation. After surgery, one patient died on day 34 and another, after 3 years. CONCLUSION: Lung decortications, re-expanding the affected lung, ensures symptom remission and improves quality of life of patients with trapped lung after coronary bypass grafting in the long-term.

A comparative in vitro study of frictional resistance between lingual brackets and stainless steel archwires.

Friction between archwires and labial brackets has received considerable attention; however, information on the frictional behaviour of commercially available lingual brackets is limited. The aim of this study was to investigate the frictional resistance resulting from a combination of lingual orthodontic brackets (7th Generation, STb, Magic, and In-Ovation L) and stainless steel archwires at 0, 5, and 10 degrees of second-order angulation. Each bracket type (n = 30) was tested with three different sizes of archwires. Static and kinetic frictional forces were evaluated with a universal testing machine. Statistical analysis of the data was performed with non-parametric Kruskal-Wallis and Dunn's multiple comparison tests. All tested brackets showed higher frictional forces as the wire size and second-order angulation increased. The lowest friction was found with In-Ovation L brackets and 0.016 inch archwires at 0 degrees angulation, and the greatest friction with a combination of STb brackets and 0.017 × 0.025 inch archwires at 10 degrees angulation. For all combinations, Magic and In-Ovation L brackets showed lower frictional resistance when compared with 7th Generation and STb brackets. The slot width (occluso-gingival dimension) of the brackets, measured using the optics of a microhardness machine, showed that all brackets were oversized and that Magic brackets had the largest slot width. Surface roughness of the brackets investigated using atomic force microscopy and scanning electron microscopy, demonstrated that the 7th Generation brackets had the greatest surface roughness.

[Tracheobronchial injuries]. / Trakeobronsiyal yaralanmalar.

BACKGROUND: We aimed in this study to investigate and compare the diagnostic and therapeutic methods in tracheobronchial injuries. METHODS: Nine cases (7 male, 2 female) operated between 2003 and 2008 because of tracheobronchial injury were included in the study. The cause of tracheobronchial injury was trauma in 7 cases and postintubation laceration in 2 cases. The cases were evaluated in terms of age, sex, type of trauma, clinical findings, localization of injury, performed diagnostic and therapeutic methods, and results. RESULTS: The causes of tracheobronchial laceration were blunt trauma in 6 cases, penetrating trauma in 1 case and iatrogenic (postintubation) in 2 cases. Lacerations were in the trachea in 5 cases and at the bronchial level in 4 cases. Operations included right upper bilobectomy in 1 case, tracheal resection and end to end anastomosis in 1 case, end to end anastomosis in 3 cases, and primary repair in 4 cases. One case died during the operation and 1 case died postoperatively. CONCLUSION: In tracheobronchial injuries, early diagnosis and treatment are very important. The most useful method is bronchoscopy for determining the type and localization of the injury. In treatment, primary repair should be preferred over anatomical resections whenever possible.

Long-term results of diaphragmatic plication in adults with unilateral diaphragm paralysis.

BACKGROUND: In this study we aimed to evaluate the long-term outcome of diaphragmatic plication for symptomatic unilateral diaphragm paralysis. METHODS: Thirteen patients who underwent unilateral diaphragmatic plication (2 patients had right, 11 left plication) between January 2003 and December 2006 were evaluated. One patient died postoperatively due to sepsis. The remaining 12 patients [9 males, 3 females; mean age 60 (36-66) years] were reevaluated with chest radiography, flouroscopy or ultrasonography, pulmonary function tests, computed tomography (CT) or magnetic resonance imaging (MRI), and the MRC/ATS dyspnea score at an average of 5.4 (4-7) years after diaphragmatic plication. RESULTS: The etiology of paralysis was trauma (9 patients), cardiac by pass surgery (3 patients), and idiopathic (1 patient). The principle symptom was progressive dyspnea with a mean duration of 32.9 (22-60) months before surgery. All patients had an elevated hemidiaphragm and paradoxical movement radiologically prior to surgery. There were partial atelectasis and reccurent infection of the lower lobe in the affected side on CT in 9 patients. Atelectasis was completely improved in 9 patients after plication. Preoperative spirometry showed a clear restrictive pattern. Mean preoperative FVC was 56.7 ± 11.6% and FEV1 65.3 ± 8.7%. FVC and FEV1 improved by 43.6 ± 30.6% (p < 0.001) and 27.3 ± 10.9% (p < 0.001) at late follow-up. MRC/ATS dyspnea scores improved 3 points in 11 patients and 1 point in 1 patient at long-term (p < 0.0001). Eight patients had returned to work at 3 months after surgery. CONCLUSIONS: Diaphragmatic plication for unilateral diaphragm paralysis decreases lung compression, ensures remission of symptoms, and improves quality of life in long-term period.

Simultaneous open-heart surgery and pectus deformity correction.

PURPOSE: Pectus deformities and cardiac problems sometimes require simultaneous surgery. We report our experience of performing this surgery and review the relevant literature. METHODS: We performed simultaneous pectus deformity correction and open-heart surgery in six patients between 1999 and 2006. The pectus deformities were pectus carinatum in one patient and pectus excavatum in five patients. The cardiac problems were coronary artery disease in one patient, an atrioseptal defect (ASD) with a ventricular septal defect (VSD) in one, a VSD in one, mitral valve insufficiency with left atrial dilatation in one, and an ascending aortic aneurysm with aortic valve insufficiency caused by Marfan's syndrome in two. We corrected the pectus deformities using the modified Ravitch's sternoplasty in all patients. First, while the patient was supine, we resected the costal cartilage; then, after completing the cardiac surgery, the sternum was closed and the additional time required for the pectus operation was calculated for each patient. Patients were examined 1, 4, and 6 months postoperatively. RESULTS: The average operation time was 102 min, and there were no major complications. The pectus bars were removed 4-6 months postoperatively. Good cardiac and cosmetic results were achieved in all patients, who were followed up for 5 years. CONCLUSIONS: Concomitant pectus deformity correction and open-heart surgery can be performed safely, eliminating the risks of a second operation in a staged procedure.
