ABSTRACT

Chyloptysis and chylomediastinum are uncommon complications of various kinds of thoracic operations, malign and nonmalign diseases. In the English language medical literature, there were no cases of both chylomediastinum and chyloptysis following trauma. We discuss a case of chylomediastinum and chyloptysis after penetrating trauma. The patient sustained a bullet wound that caused chylomediastinum and chyloptysis without damaging major structures apart from the thoracic duct in the mediastinum. Following surgical intervention, the patient has remained problem-free for 5 months.

ABSTRACT

Fibrodysplasia ossificans progressiva is an extremely rare disease that is usually seen in the form of sporadic cases and seems to be localized outside of the thoracic cavity. Inflammation and trauma are accused in the etiology, and too many diagnostic mistakes are done. The disease, which may present genetic transmission and has not a definitive treatment, was seen as an intrathoracic mass for the first time. Intrathoracic mass was excised, and the cure was achieved in our patient, who was defined to be sporadic as a result of familial screening.

ABSTRACT

BACKGROUND: Conventional treatment methods in postpneumonectomy empyemas (PPE) are associated with long stay in hospital, poor patient comfort, and high rate of postoperative mortality. Vacuum-assisted management (VAM) may be helpful in solving these problems. METHODS: VAM was performed on nine patients with PPE in our clinic between July 2010 and September 2011 to provide continuous drainage of empyema in the pouch and to improve empyema with obliteration of the pouch by accelerating tissue granulation. RESULTS: All nine patients were men (mean age: 54.5 years; range: 18-68 years). Empyema resolution and obliteration of the pouch were achieved with VAM in the cases with empyema without fistula (n = 7) after the pneumonectomy. In the patients with fistula (n = 2), VAM was performed after closure of the fistula. Mean duration of hospital stay was 36.5 (12-57) days. The treatment was successful in eight of nine patients (88.9%). Mean duration of follow-up in the successfully treated patients was 10.9 (3-17) months. CONCLUSION: Intrathoracic VAM was effective and safe in the treatment of PPE.

ABSTRACT

Pneumothorax is the accumulation of air in the pleural space. Pneumothorax may occur spontaneously (primary spontaneous pneumothorax, PSP). Chest tube drainage (CTD) is the most common choice for treatment of PSP. This study aimed to evaluate patients treated with CTD, regarding demographic and diagnostic characteristics, and to compare the effectiveness of apical and axillary approaches. We retrospectively analyzed a total of 217 patients with PSP regarding symptoms, duration of complaints, and treatment procedures. There were 196 (90.3%) male patients and mean age was 25.22 ± 5.37 years. The approach of CTD was determined randomly; being performed with the apical approach on 93 (42.9%) and axillary on 124 patients (57.1%). There were no statistically significant differences between the two groups in terms of age, sex, BMI, collapse size, and complaint duration. However, a statistically significant relationship was determined between collapse size and leading symptoms where the significance was related to dyspnea (p < 0.001). This led to the thought that dyspnea increases with the increase of collapse size. The patients who were admitted to hospital in the later term when compared with others, had a larger collapse size (p < 0.001). This also led to the thought that collapse increases in relation to time due to late admission of patients. Hospitalization time was significantly shorter in patients who had apical CTD (p < 0.001). In conclusion, inserting the tube from the apex could shorten the treatment period.

ABSTRACT

Foreign body aspiration in childhood is a common and life-threatening emergency. A 14-year-old male with history of mental retardation was transferred from another center to our hospital with diagnosis of foreign body aspiration. According to the anamnesis, he had been diagnosed with epilepsy a few years ago. Approximately 10 hours before admission, while at home, his parents had urgently placed a wooden spoon in the boy's mouth during a generalized tonic-clonic seizure to avoid possible airway injury. Nevertheless, he had inhaled a large piece of the wood after breaking the handle of the spoon with his teeth. Rigid bronchoscopic evaluation revealed the presence of a large piece of wood sitting vertically 2 cm beyond the glottis. Although bronchoscopic removal of the wooden piece from the trachea was difficult and prolonged, it was successful. Following this process, he presented with subcutaneous emphysema and pneumothorax in the intensive care unit (ICU). After improvement with the aid of chest tube drainage in the ICU, he was discharged from the hospital on the 3rd day of rigid bronchoscopy. Early diagnosis and urgent removal of a foreign body are very important for reducing mortality. However, complications related to the foreign body itself or the bronchoscopy may occur. In conclusion, the physical characteristics, position and location of the foreign body can influence the outcome, even in skilled hands.

ABSTRACT

BACKGROUND: Diaphragm plication surgery is conducted to remove dyspnea, which results from mediastinal shift, atelectasia, and ventilation/perfusion dyssynchrony in lungs that occur because of an eventrated diaphragm. This study aims to determine whether diaphragm plication has any effect on respiration by analyzing the patients' changing values in the respiratory function test (RFT) after plication surgery. METHODS: Sixteen patients who underwent diaphragm plication surgery in our clinic because of plication eventration or paralysis were examined prospectively. Diaphragm eventration values were assessed using a calculation method that uses posteroanterior pulmonary radiographies taken during patient admission and control; then, these data were recorded. The amount of changes in the eventration levels and in restrictive respiratory failure parameters-forced expiratory volume in 1 second (FEV1), forced vital capacity (FVC) of RFTs-conducted in pre- and postoperative control periods were compared using statistical analysis methods. The compatibility between the amounts of RFT changes was examined through a satisfaction survey-using a questionnaire that consisted of multiple choice questions with answer options such as "better," "the same," and "worse"-to understand preoperative and postoperative symptom levels in the 12(th) month of postoperative control. RESULTS: According to postoperative levels, a decrease between 19% and 23% was observed in eventration amounts within the 1(st) postoperative month, 6(th) postoperative month, and 12(th) postoperative month. In addition, the highest average increase in FEV1 liter (lt) values was 0.2 lt and 0.25 in FVC (lt) values. CONCLUSION: Researchers of this study believe that more distinctive decisions need to be taken while identifying patients for surgery in unilateral diaphragm eventrations, especially in the adult patient group; surgical option should be used for cases in which the eventrated diaphragm results in mediastinal shift and respiratory failure.

ABSTRACT

OBJECTIVES: The objective was to describe changing patterns of etiological factors and treatment modalities for massive hemoptysis. MATERIAL AND METHODS: From January 2008-December 2012, the medical records of 58 massive hemoptysis patients were reviewed. RESULTS: Fifty-eight patients, 44 were men (75.9%) and 14 were women (24.1%), with a mean age of 51.4 years (range= 19-84 years), were divided into three groups; surgical management (n= 37, 63.8%), conservative management (n= 14, 24.1%) and bronchial artery embolization (n= 6, 10.4%). One case (1.7%) had combined treatment modality; bronchial artery embolization was followed by surgical resection. Anatomical lung resections were the most preferred resection type in the surgical management group (n= 34, 91.9%). The most common etiological factor was bronchiectasis (n= 19, 32.8%); followed by bronchial cancer (n= 14, 24.1%). The duration of hospitalization in the surgical management group was 11.4 days (range= 4-24); whereas in the bronchial artery embolization group, hospitalization was only four days (range= 2-7) (p< 0.01). Prolonged air leak (n= 7; 18.9%) was the most common complication in the surgical management group. CONCLUSION: We emphasize that bronchiectasis was leading cause of massive hemoptysis. Surgical treatment remains the definitive therapy in the management of massive hemoptysis with decreased mortality rates over decades; whereas bronchial artery embolization is an effective therapeutic tool.

ABSTRACT

BACKGROUND/AIM: Alpha-methylacyl-CoA racemase (AMACR), an intracellular enzyme involved in lipid metabolism, has emerged as an immunohistochemical marker for many types of cancer. Recent studies about the role of lipid metabolism in pathogenesis of mesothelioma have brought up some positive results. This study was conducted to investigate AMACR expression in the diagnosis of malignant pleural mesothelioma (MPM) and the correlation of this marker with clinical characteristics and survival. MATERIALS AND METHODS: The clinicopathologic characteristics and resection materials of 71 patients were reviewed retrospectively. AMACR expression was evaluated immunohistochemically. The correlations among AMACR expression, clinicopathologic factors, and survival were investigated. RESULTS: AMACR expression was detected in 42.3% of the study group. The specificity and sensitivity of AMACR immunostaining in detecting mesothelioma were 41.1% and 42.3%, respectively. AMACR-positive and negative groups were similar for age, sex, smoking history, tumor diameter, lymph node involvement, differentiation, T-N factor, and stage. Overall survival was not significantly different between the groups, either. CONCLUSION: The sensitivity of immunostaining was not high enough to use AMACR as a diagnostic tool in MPM. AMACR expression did not have a prognostic value in MPM, either.

ABSTRACT

OBJECTIVE: Hydatid disease is endemic in many countries throughout the world. Although we do not have exact figures, the disease is prevalent in Turkey. A considerable number of patients have additional liver cysts as well. In this study we reviewed our experience with hydatid disease of the lung and liver and discussed the principles of treatment. METHODS: From 1971 to 1999, 2509 patients with pulmonary hydatidosis were referred to us, and 485 of them had concomitant liver cysts. Of these, 405 patients had cysts located on the dome of the liver, and they were operated on with phrenotomy through a right thoracotomy. Eighty patients who were found to have concomitant liver cysts in the lower part of the liver were referred to general surgery for a laparotomy. RESULTS: Hydatid cysts located in the lungs were managed by means of cystotomy and capitonnage. For liver cysts, cystotomy and inversion of the cavity with sutures was the surgical method of choice, and a drain was left in place. In case of multiple cysts in the liver, needle aspiration was preferred. Twelve major complications, including excessive biliary drainage and bronchobiliary fistula, occurred in these patients. CONCLUSIONS: We believe that management of pulmonary and hepatic cysts simultaneously through the thoracic route is convenient and should be encouraged in patients because this prevents a second operation. Needle aspiration can be applied only for liver cysts. It is absolutely contraindicated in lung hydatid cysts.

ABSTRACT

A 13-year-old girl was admitted to our clinic with the complaints of dyspnea, abdominal distention, cough, and right-sided chest pain.The diagnosis of disease was made with physical examination and radiologic evaluation. She underwent right thoracotomy and phrenotomy for the management of the hydatid cysts of the lung and the liver. The postoperative course was uneventful and she was discharged on the 10th postoperative day. We believe that the simultaneous management of concomitant pulmonary and hepatic hydatid cysts through a thoracicroute is a convenient option.

ABSTRACT

BACKGROUND: Localized fibrous tumors of the pleura, which are considered to originate from submesothelial connective tissue, are rare. The purpose of this study was to investigate the clinical features of these tumors and to determine the optimal treatment and follow-up. METHODS: The records of 10 consecutive patients with localized fibrous tumors of the pleura operated on at the Ataturk Center for Chest Diseases and Thoracic Surgery between 1995 and 2001 were retrospectively reviewed. Diagnostic procedures, clinical courses, and outcomes of these patients were studied. Total excision through a thoracotomy was performed in all of the patients. Pneumonectomy was required in 1 patient because of a giant intraparenchymal localized fibrous tumor of the pleura. Additional partial chest wall resections were done in 2 patients. RESULTS: The size of excised tumors ranged from 10 x 8 x 4 cm to 30 x 25 x 20 cm. Malignant transformation was seen in 1 patient 22 months after resection of a benign tumor. Four cases were pathologically considered to be malignant. All patients except 1 are alive (follow-up 16 to 57 months after resection). CONCLUSIONS: Although localized fibrous tumors of the pleura are considered histologically benign tumors, because of the risk of recurrence and malignant transformation, complete surgical resection is indicated and long-term follow-up is recommended in all patients.

ABSTRACT

OBJECTIVE: A rib fracture secondary to blunt thoracic trauma is an important indicator of the severity of the trauma. In the present study we explored the morbidity and mortality rates and the management following rib fractures. METHODS: Between May 1999 and May 2001, 1417 cases who presented to our clinic for thoracic trauma were reviewed retrospectively. Five hundred and forty-eight (38.7%) of the cases had rib fracture. There were 331 males and 217 females, with an overall mean age of 43 years (range: 5-78 years). These patients were allocated into groups according to their ages, the number of fractured ribs and status, i.e. whether they were stable or unstable (flail chest). RESULTS: The etiology of the trauma included road traffic accidents in 330 cases, falls in 122, assault in 54, and industrial accidents in 42 cases. Pulmonary complications such as pneumothorax (37.2%), hemothorax (26.8%), hemo-pneumothorax (15.3%), pulmonary contusion (17.2%), flail chest (5.8%) and isolated subcutaneous emphysema (2.2%) were noted. 40.1% of the cases with rib fracture were treated in intensive care units. The mean duration of their stay in the intensive care unit was 11.8+/-6.2 days. 42.8% of the cases were treated in the wards whereby their mean duration of hospital stay was 4.5+/-3.4 days, while 17.1% of the cases were followed up in the outpatient clinic. Twenty-seven patients required surgery. Mortality rate was calculated as 5.7% (n=31). CONCLUSIONS: Rib fractures can be interpreted as signs of significant trauma. The greater the number of fractured ribs, the higher the mortality and morbidity rates. Patients with isolated rib fractures should be hospitalized if the number of fractured ribs is three or more. We also advocate that elderly patients with six or more fractured ribs should be treated in intensive care units due to high morbidity and mortality.

ABSTRACT

OBJECTIVE: With the changing clinical presentation and histopathological pattern, carcinoids are now considered as a distinct and well-defined group in the neuroendocrine tumour scale. Surgery, especially parenchyma-sparing operations, are the treatment of choice for carcinoids. METHODS: Over a 25-year period, 83 patients with typical carcinoid tumour underwent thoracotomy on in our institution. The records of the patients were reviewed and the results were evaluated. RESULTS: The diagnosis was made with radiological methods and bronchoscopy. Cough and recurrent pneumonia were the most common symptoms. A variety of surgical procedures were performed. Thirty of the 83 patients underwent tissue-saving operations. Twenty patients underwent bronchotomy excision, eight were managed with sleeve or partial sleeve resective procedures, and two underwent segmentectomy. CONCLUSIONS: Conservative surgery is the treatment of choice of carcinoids, which were histologically typical and anatomically endobronchial. Especially for polypoid type carcinoids and for selected cases with sessile type, bronchotomy with simple excision and sleeve resections is a simple and effective method. As these types of operations produce a better functional result, they should be encouraged in these patients.

ABSTRACT

Records of 59 patients (41 males and 18 females) who underwent 70 operations for pulmonary aspergilloma in a 23-year period were examined retrospectively. Sixty-three operations were for primary treatment of pulmonary aspergilloma, and 7 were for complications of surgery. Twenty-six postoperative complications occurred in 19 patients. Three lobectomies that resulted in bronchopleural fistula were managed by intercostal muscle-flap closure and partial thoracomyoplasty. Two patients died within the first week of surgery. Surgery is the treatment of choice for most patients with pulmonary aspergilloma. Selective bronchial artery embolization is helpful only in combating hemoptysis, and this has been considered a temporary measure in most reports. Thus, open thoracotomy and anatomical resection are recommended as early as possible after the diagnosis is established.

ABSTRACT

The lung is most common site for metastatic disease via hematogenous route. Tumor emboli of the vessels of the lung induces fibrocellular and fibromuscular intimal proliferation. These histopathological changes may cause pulmonary tumor trombotic microangiopaty. Few cases are diagnosed antemortem. We report a 60 year old woman with by metastatic epithelioid angiosarcoma involving the lung. Tumor cells were positive for VEGF and topoisomerase II. VEGF may be involved in the pathogenesis pulmonary tumor trombotic microangioapy and topoisomerase II positivity showed sensitivity against catalytic topoisomerase II inhibitors.

ABSTRACT

Pulmonary endometriosis is a rarely seen disease of the lung. On computed tomography, a cavitary lesion of 15 × 26 in size was detected in the lung parenchyma of a 38-year-old female patient who was examined due to hemoptysis. The pathologic result of the surgically excised cavitary lesion was reported as pulmonary endometriosis.

ABSTRACT

Lung cancer, which is mainly affected by environmental factors, is a lethal malignancy. It is also important to investigate the effect of genetic factors on lung cancer aetiology. In this study, we aimed to investigate the distribution of CYP1A1*2C, GSTT1 and GSTM1 polymorphisms in Turkish lung cancer patients to determine whether any promoting effect of polymorphisms could cause development of lung cancer. For this purpose, genomic DNA samples obtained from peripheral blood of 128 patients with lung cancer and 122 healthy subjects were analyzed. Genotyping of polymorphic enzymes were carried out by polymerase chain reaction-restriction fragment length polymorphism methods. Although there were no significant differences between groups in terms of CYP1A1 polymorphism, the carriers of CYP1A1 Ile/Val genotype (odds ratio [OR] = 1.224, 95% confidence interval [CI]: 0.585-2.564) or CYP1A1 Val/Val genotype (OR = 3.058, 95% CI: 0.312-30.303) had an increased risk of lung cancer development. There was no statistical difference between groups in terms of both GSTT1 null genotype (OR = 1.114, 95% CI: 0.590-2.105) and GSTM1 null genotype (OR = 0.776, 95% CI: 0.466-1.290). This is the first case-control study investigating CYP1A1 Ile/Val, GSTT1 and GSTM1 polymorphisms in Turkish lung cancer patients. Although we suggest that other genes in addition to the proposed genes could play a role in lung cancer development, the results of our study will contribute to the possible associations between CYP1A1 Ile/Val, GSTT1 and GSTM1 gene polymorphism on the risk of lung cancer.

ABSTRACT

OBJECTIVES: This study is conducted to show the relationship between visceral pleural, lymphovascular, and perineural invasion, and other clinicopathologic characteristics and their significance as prognostic factors. METHODS: The clinicopathologic characteristics of 289 patients who underwent a potentially curative surgical resection between 2000 and 2009 in our clinic were reviewed retrospectively. The prognostic factors were then evaluated by univariate and multivariate analysis. The patients who were given neoadjuvant-adjuvant chemotherapy and/or radiotherapy and who died due to postoperative mortality were excluded. Data from 188 patients were analyzed. RESULTS: Out of the 188 patients (108 diagnosed as adenocarcinoma and 80 squamous cell carcinoma), 66 patients had lymphovascular invasion, 53 patients had perineural invasion, and 92 patients had visceral pleural invasion. Visceral pleural invasion was related with T factor, tumor histology, dimension, stage, and differentiation. Lymphovascular invasion was related with N status and stage. Perineural invasion was observed more frequently in tumors with moderate/poor differentiation. Visceral pleural and lymphovascular invasion were found to be poor prognostic factors but we could not show statistically meaningful effect of perineural invasion on survival. CONCLUSION: The presence of visceral pleural or lymphovascular invasion can show higher risk of mortality whereas perineural invasion has no effect on prognosis.

ABSTRACT

OBJECTIVE: Pulmonary carcinoid tumors are rare low-grade malignant neoplasms and constitute 2-5% of all lung tumors. In this study, we aimed to determine the clinical presentations, types of surgery, long-term treatment outcomes and survival rates of patients diagnosed with carcinoid tumor treated surgically in our clinic. METHODS: Patients operated in our clinic between 1992 and 2008 with confirmed or suspected diagnoses of carcinoid tumors were included in our study. Patients' hospital records were retrospectively analyzed. RESULTS: A total of 104 patients (age 19-71 years, mean 44±13 years, 2 SD) with pathologically confirmed carcinoid tumor were analyzed. A total of 84 patients (81%) were diagnosed as typical and the remaining 20 (19%) being atypical carcinoid tumor. As many as 24 patients (23%) were asymptomatic. The most frequent symptom was recurrent respiratory infection (35%). The most used surgical procedures were lobectomy (47%) and bilobectomy (16%). Mean postoperative follow-up period was 72 months (6-190 months). No surgery related mortality was noticed. As many as 15 (14%) patients died during the follow-up period. Overall 5- and 10-year survival rates were 89% and 72%, respectively. For typical carcinoid tumors, the 5- and 10-year survival rates were 92% and 83%, and for atypical carcinoids 73% and 46%, respectively (p<0.001). CONCLUSIONS: In our study, we noticed histological subtype, stage of the disease and the type of surgery performed to be prognostic factors of carcinoid tumors. Atypical carcinoid tumors tend to be more metastatic and had worse prognosis when compared with typical carcinoid tumors. We conclude that surgery is the best treatment of choice for carcinoid tumors, especially parenchyma-sparing procedures, because of their good mid- and long-term survival rates.
