A new technique for closure of pericardial defects: pericardial rug weave.

BACKGROUND: Pericardial defect that occurs after intrapericardial pneumonectomy can cause many fatal complications, and closing the defect with mesh is a widely used surgical method to prevent these complications. METHODS: Data of patients who underwent intrapericardial pneumonectomy and pericardial resection in our clinic between October 2010 and June 2022 were retrospectively reviewed. Patients were divided into two groups, those who had prolene mesh used to close the pericardial defect and those who underwent the "Rug Weave" technique we proposed as an alternative, and the results were compared. RESULTS: The study included 23 patients, one of whom was female. All patients underwent surgery due to malignancy. The vast majority of the patients had a diagnosis of squamous cell lung carcinoma (86.9%). Atrium was added to three patients and rib resection was added to one patient during intrapericardial pneumonectomy and pericardial resection. There was no significant difference between the two groups in terms of average age, gender, and length of hospital stay. There was no significant difference between the two groups in terms of complications, including atrial fibrillation, which is commonly seen in these patients (p = 0.795). The Rug Weave group had an average defect width of 23.96 cm2 and was found to be advantageous in terms of overall survival compared to the mesh group (p = 0.017). CONCLUSIONS: The "Rug Weave" technique we proposed for closing pericardial defects after pneumonectomy can be used as a cheaper method safely and effectively that reduces complications as much as the traditional method of using mesh.

Importance of Histopathological Grading for Treatment Selection in Malignant Mesothelioma.

BACKGROUND: Complexities in TNM staging in epithelioid malignant pleural mesothelioma (MPM) may lead to errors in treatment selection, leading to major surgical interventions in patients with low survival expectations. METHODS: Sixty-nine stage I epithelioid MPM patients, including 27 patients treated with pleurectomy/decortication (P/D) and multimodal therapy (MMT) (the P/D [MMT] group), and 42 patients treated with chemotherapy or chemoradiotherapy (the CRT group), were included in the study. After an initial evaluation of overall survival, all patients were grouped in terms of histopathological parameters and treatment types, and then, a secondary survival evaluation was performed for the groups. RESULTS: Forty-one patients were male, the mean age was 61.8 years. The median survival time was 26 months in the P/D (MMT) group, and 19.6 months in the CRT group, but the difference was not statistically significant. After grouping according to pathological criteria, a median survival time of 32.4 ± 2.9 months in the P/D (MMT) group and 21.9 ± 3.2 months in the CRT group was obtained among patients with histopathological low-grade tumors. Among patients with high-grade tumors, the median survival time was 18.3 ± 2.6 months in the P/D (MMT) group and 17 ± 4.4 months in the CRT group. Among patients with low-grade tumors, the P/D (MMT) group had longer survival. Median survival times were similar among patients with high-grade tumors. CONCLUSION: In epithelioid MPM, histopathological grading by video-assisted thoracic surgery pleural biopsy can prove accurate in selecting patients for P/D and MMT.

High grade tumor budding is associated with poor survival in pathologic stage I lung adenocarcinoma.

AIM: Tumor budding is a significant prognostic parameter that has been related to aggressive behavior in early-stage tumors of various origins. The aim of this study was to evaluate the clinicopathological significance of tumor budding in pathologic stage (pStage) I lung adenocarcinomas. METHODS: This study comprised 107 patients who underwent curative resection for pStage I lung adenocarcinomas at our hospital between December 2010 and January 2016. We examined tumor budding on routine hematoxylin and eosin (H&E) slides from resected specimens. Tumors were categorized into two groups based on the degree of tumor budding: low grade (grade 0-1) and high grade (grade 2-3). We evaluated the relationship between tumor budding and overall survival (OS), disease-free survival (DFS) and clinicopathological parameters. RESULTS: There is a significant difference (p = 0.002) between the 5-year DFS rates of the high-grade and the low-grade tumor budding group, which were 70 % and 90 %, respectively. High-grade tumor budding positive patients from the same pathological stage (p < 0.001; HR = 2.93 [1.51-5.68]) and clinical stage (p = 0.002) had poorer cumulative survival rates than low grade tumor budding positive patients. High grade tumor budding was positively associated with spread through air spaces (STAS) (p < 0 0.001), lymphovascular invasion (LVI) (p < 0.001), tumor necrosis (p < 0.001), high SUVmax value (SUVmax>3.0) (p < 0.001), and tumor size >20 mm (p = 0.024). High-grade tumor budding was significant prognostic factor of OS (p < 0.006) and DFS (p < 0.001) on univariate Cox regression hazard model analysis. However, it did not show significance in the multivariate analysis (p > 0.05). CONCLUSIONS: High-grade tumor budding is an independent prognostic factor and associated with adverse clinicopathological features and poor survival rates. We proposed that high-grade tumor budding should be recognized as a new prognostic parameter and will be beneficial in predicting the clinical course in pStage I lung adenocarcinomas.

Non-intubated video-assisted thoracoscopic surgery under combination of erector spinae plane block and thoracic paravertebral block.

BACKGROUND: The use of anesthetics and analgesic drugs and techniques in combination yields a multimodal effect with increased efficiency. In this case series, we aimed to evaluate the anesthetic effect of the thoracic paravertebral block (TPVB) and erector spinae plane block (ESPB) combination in patients, who underwent non-intubated video-assisted thoracoscopic surgery (NIVATS). METHODS: Medical records of 16 patients, who underwent NIVATS for wedge resection under the combination of ESPB and TPVB were reviewed retrospectively. Demographic data of patients, duration of the sensory block, amount of the anesthetic agent used for premedication and sedo-analgesia, any presence of perioperative cough, operative times, postoperative visual analog scale (VAS) scores in the postoperative follow-up period, the need for additional analgesia, and patient satisfaction were reviewed. RESULTS: Of the patients included in the study, 12 were men and 4 were women. The mean age was 48.6 years and the mean BMI was 24.7 kg/m2. The mean time needed for the achievement of the sensorial block was 14 min and the mean skin-to-skin operative time was 21.4 min. During the procedure, patients received 81.5 ± 27.7 mg of propofol and 30 ± 13.6 micrograms of remifentanil infusions, respectively. The mean dose of ketamine administered in total was 58.1 ± 12.2 mg. Only 2 patients needed an extra dose of remifentanil because of recurrent cough. No patients developed postoperative nausea vomiting. During the first 24 h, the VAS static scores of the patients were 3 and below, while VAS dynamic scores were 4 and below. Morphine consumption in the first postoperative 24 h was 13.2 mg. CONCLUSIONS: In conclusion, combined ESPB and TPVB with added intravenous sedo-analgesia in the presence of good cooperation between the surgical team and the anesthesiologist in the perioperative period can provide optimal surgical conditions including the prevention of cough in NIVATS. It is not sufficient to state that this combination is superior to alone ESPB or alone TPVB, as it is a preliminary study with a limited number of cases.

Computed Tomography-Guided Methylene Blue Labeling Prior to Thoracoscopic Resection of Small Deeply Placed Pulmonary Nodules. Do We Really Need Palpation?

Background Video-assisted thoracic surgery (VATS) is widely used for thoracic surgery operations, and day by day it becomes routine for the excision of undetermined pulmonary nodules. However, it is sometimes hard to reach millimetric nodules through a VATS incision. Therefore, some additional techniques were developed to reach such nodules little in size and which are settled on a challenging localization. In the literature, coils, hook wires, methylene blue, lipidol, and barium staining, and also ultrasound guidance were described for this aim. Herein we discuss our experience with CT-guided methylene blue labeling of small, deeply located pulmonary nodules just before VATS excision. Method From April 2013 to October 2016, 11 patients with millimetric pulmonary nodules (average 8, 7 mm) were evaluated in our clinic. For all these patients who had strong predisposing factors for malignancy, an 18F-FDG PET-CT scan was also performed. The patients whose nodules were decided to be excised were consulted the radiology clinic. The favorable patients were taken to CT room 2 hours prior to the operation, and CT-guided methylene blue staining were performed under sterile conditions. Results Mean nodule size of 11 patients was 8.7 mm (6, 2-12). Mean distance from the visceral pleural surface was 12.7 mm (4-29.3). Four of the nodules were located on the left (2 upper lobes, 2 lower lobes), and seven of them were on the right (four lower lobes, two upper lobes, one middle lobe). The maximum standardized uptake values (SUV max) on 18F-FDG PET/CT scan ranged between 0 and 2, 79. Conclusion CT-guided methylene blue staining of millimetric deeply located pulmonary nodules is a safe and feasible technique that helps surgeon find these undetermined nodules by VATS technique without any need of digital palpation.

Efficiency of pulmonary nodule risk scoring systems in Turkish population.

Malignancy risk calculation models were developed using the clinical and radiological features. It was aimed to compare pulmonary nodule risk calculation models and evaluate their effectiveness and applicability for the Turkish population. Between 2014 and 2019, 351 patients who were operated on for pulmonary nodules were evaluated with the following data: age, gender, smoking history, family history of lung cancer, extrapulmonary malignancy and granulomatous disease, nodule diameter, attenuation character, side, localization, spiculation, nodule count, presence of pulmonary emphysema, FDG uptake in PET/CT of the nodule, and definitive pathology data. Malignancy risk scores were calculated using the equations of the Brock, Mayo, and Herder models. The results were evaluated statistically. The mean age of the 351 patients (236 men, 115 women) was 57.84 ± 10.87 (range 14-79) years, and 226 malignant and 125 benign nodules were observed. Significant correlations were found between malignancy and age (p < 0.001), nodule diameter (p < 0.001), gender (p < 0.009), speculation (p < 0.001), emphysema (p < 0.05), FDG uptake (p < 0.001). All three models were found effective in the differentiation (p < 0.001). The ideal threshold value was determined for the Brock (19.5%), Mayo (23.1%), and Herder (56%) models. All models were effective for nodules of > 10 mm, but none of them were for 0-10 mm. Brock was effective in ground-glass nodules (p = 0.02) and all models were effective for semi-solid and solid nodules. None of the groups could provide AUC values as high as those achieved in the original studies. This suggests the need to optimize models and malignancy risk thresholds for Turkish population.

Analysis of bronchiectasis patients who underwent video-assisted thoracoscopic surgery in a tertiary thoracic surgery center: Ten years of experience.

Background: This study aimed to analyze our video-assisted thoracic surgery (VATS) experience in the surgical treatment of bronchiectasis and the reasons limiting VATS application. Methods: Two hundred one patients (106 males, 95 females; mean age: 39.7±14.1 years; range, 12 to 68 years) who underwent surgical treatment for bronchiectasis between January 2012 and October 2021 were included in the retrospective study. Three groups were created based on the surgical technique used: VATS, thoracotomy, and patients who were converted from VATS to thoracotomy. Results: The most significant presenting symptoms were cough (43%) and excessive sputum expectoration (40%). Surgical intervention was applied to the left side of 60% of the patients, and the most common resection performed in all three groups was left lower lobectomy. The rate of conversion from VATS to thoracotomy was 28.8%, and it was found that dense pleural adhesions were the most common reason. Revision surgery was performed on a total of 11 (5.47%) patients. The frequency of revision surgery did not differ significantly among the three groups (p=0.943). The most common postoperative complication was prolonged air leakage. There was no statistically significant difference in postoperative complication rates among the groups (p=0.417). The rate of surgical treatment of bronchiectasis with VATS was observed to have increased from 11.1% to 77.7% in our clinic. Conclusion: In experienced hands, VATS can be safely applied in the surgical treatment of bronchiectasis.

The importance of coordination in preventing overdiagnosis: a retrospective analysis of unabsorbed oxidized regenerated cellulose.

BACKGROUND: Oxidized regenerated cellulose (ORC) is commonly used to control small intraoperative bleedings in lung cancer surgery. However, difficulties in its absorption may lead to complications that can mimic malignancy recurrence in the affected areas, and may require further examination. METHODS: Between 2015 and 2022, patients who underwent malignant tumour resection and lymph node dissection and were subsequently evaluated for suspected lymph node recurrence and underwent EBUS-guided needle biopsy were included in the study. Pathology reports of these patients showed an ORC-related foreign body type granulomatous reaction. Such reactions, caused by delayed absorption of ORC, can mimic malignancy recurrence and result in unnecessary biopsies. RESULTS: In a total of 13 patients (10 males), pathology was observed in 18 lymph node areas after malignant resection and lymph node dissection, and ORC was detected in subcarinal and inferior paratracheal lymph node areas in all patients. The average age of the patients was calculated as 63.1 years (range 51-74). The mean SUVmax value observed in these lymph node areas on PET/CT was 5.22 (range 0-14.36). Although the SUVmax value decreased as the time between surgery and EBUS increased, no statistically significant difference was observed (p = 0.100). CONCLUSION: The study suggests that in cases of suspected unexpected lymph node recurrence in postoperative follow-up of lung cancer, it is important for clinicians to communicate with the surgeon and re-evaluate the use of ORC by reviewing the operative notes. This may help in determining an appropriate further investigation strategy.

Are precautions actually a risk factor in the development of bronchopleural fistula after pneumonectomy? A retrospective analysis of 299 cases.

PURPOSE: Bronchopleural fistula most commonly occurs after pneumonectomies, with high morbidity and mortality. A preventive approach is essential. Risk factors can be classified depending on the patient, anatomy, surgical technique, and other causes. METHODS: Patients (n = 370) who underwent pneumonectomy between 2010 and 2020 were evaluated. The digital media and archive files of the patients (n = 299) were reviewed retrospectively. RESULTS: While 271 patients (90.6%) were male, 28 (9.4%) were female. The mean age was 56.63 years. The bronchopleural fistula rate was 14.7% (44/299). Serum protein deficiency, right pneumonectomy, completion pneumonectomy, bronchial manual suturing, advanced stage, prolongation of time after neoadjuvant therapy, length of drain and hospital stay, tissue support for the stump, and short bronchial stump were significant for bronchopleural fistula. Smoking in patients operated on for malignancy and low serum albumin value in benign and chronic infectious diseases were significant in terms of fistula. In patients who developed bronchopleural fistula, the 5-year survival rate was 18.4%. CONCLUSION: The most important risk factors in bronchopleural fistula depend on the surgical technique and so are completely preventable. Contrary to the literature, short stump and tissue support to the stump were found to be risk factors for fistula. In addition, the effect of the time between neoadjuvant therapy and operation should be examined in further studies.

Pulmonary Langerhans cell histiocytosis; characteristics of 11 cases.

INTRODUCTION: Pulmonary Langerhans cell histiocytosis (PLCH) is a rarely seen disease of younger population. Almost all of the patients were smoker. In this study we aimed to evaluate the characteristics, diagnosis, treatment modalities and prognosis of 11 cases with PLCH. MATERIALS AND METHODS: We retrospectively reviewed our case series of eleven patients who were pathologically diagnosed as PLCH. The median age was 35 years (19-51) and male to female ratio (M/F) was 5/6. All of the patients were symptomatic. The most common symptoms were dyspnea (81.8%) and dry cough (72.7%). Mean duration of the symptoms was 10.8 months. All patients except two of them were smoker (81.8%). All patients were also passive smokers. RESULTS: Bilateral cystic appearance (n= 9, 81.8%), interstitial findings [septal and peribronchovascular thickening (72.7%) and nodular pattern (54.5%)] were common radiological findings. Spontaneous pneumothorax was present in two cases. All patients were diagnosed with surgical biopsies (90.9%) or transbronchial parenchymal biopsy (9.1%). Smoking cessation (81.8%) and immunosupression therapy (methylprednisolone) were the treatment modalities. Mean follow-up period was 5.40 ± 1.78 years. Generally, symptoms were improved with smoking cessation or methylprednisolone therapy. One patient was readmitted to our clinic with recurrent pneumothorax. In conclusion, it should be kept in mind that passive smoking is also responsible in the pathogenesis of PLCH. CONCLUSION: Exact consensus for PLCH treatment was not present except a few recommendations. In the future, with the understanding of the pathogenesis of the disease, new therapeutic agents will be discovered for this rare condition.

Role of orthopedia homebox protein in subclassification of pulmonary carcinoid tumors: Retrospective analysis of 110 cases.

Background: Orthopedia homeobox protein (OTP), highlighted as a sensitive and specific marker for pulmonary carcinoids, may provide a more objective criterion for subclassification. Materials and Methods: A total of 110 patients who underwent surgery for pulmonary carcinoids (2009-2019) were included. Gender, age, application complaint, tumor diameter and location, typical and atypical tumor type, lymph node involvement, stage, recurrence, and survival data were evaluated retrospectively with OTP nuclear staining. Results: The sensitivity of OTP was 66.4%. OTP in subclassifying pulmonary carcinoids was not significant. There was no significant relationship between OTP and lymph node involvement, recurrence, and survival. Conclusion: OTP does not provide significant results in the subclassification of typical and atypical carcinoid tumors and the evaluation of recurrence and survival of carcinoid tumor cases.

[The third primary-the second metachronous lung cancer in the same patient]. / Ayni hastada üçüncü primer-ikinci metakron akciger kanseri.

Having more than one lung carcinoma in an organism is called as multiple primary lung carcinoma. The probability of having a second primary lung carcinoma in the same patient at the different times is very rare.Third primary lung carcinoma has not been reported in literature before. A sychronous mass was determined on a 67 years old man about eight years ago. The mass was localized on the left upper lobe and it's histologic type was squamous cell carcinoma/adenosquamous cell carcinoma (bronchioalveolar component). A left upper lobectmy was performed with a left thorocotomy. Thirty nine months after that operation a metachronous epidermoid carcinoma was determined on the right upper lobe, consequently a right upper lobectomy was performed to him. A squamous cell carcinoma was determined on the right intermedier bronch as a third time and second metachronous 49 months later after the first operation. After all he underwent chemotherapy. We reported this case because of a second metachronous tumour in the same patient has not been reported before and to emphasize the effects of postoperative follow up on the prognosis.

An extremely rare case of multiple calcifying tumor of the pleura.

Calcifying fibrous tumors are uncommon lesions. These lesions are made up of hyalinized collagenous fibrotic tissues interspersed with lymphoplasmacytic infiltrates and extensive dystrophic calcifications mimicking psammomatous features. Calcifying tumor of pleura is rarely presented. Multiple calcifying tumor of pleuras have been reported extremely seldom. Forty-year-old male patient was admitted to our clinic with complaints of dyspnea. Because of the multiple soft tissue formations at the pleural region with the largest diameter of 2 cm on thorax computed tomography, surgical intervention was planed. Frozen sections of pleural biopsies that were taken during video-assisted thoracoscopic surgery were reported as calcifying fibrous tumor. Because of the presence of multiple lesions and pleural adhesions, curative pleural decortication was performed. This case is presented with extremely rare entity of multiple calcifying tumor of plevras.

Small cell osteosarcoma of rib: diagnosis and treatment of the rare case.

Small cell osteosarcomas are very rare tumors which are classified as the component of Ewing's sarcoma family. Although the tumor generally is seen on long bones, short bone involvement is rare. Moreover, rib localization is quite uncommon and to the best of our knowledge, only one case has been reported so far. Herein, we described a case of rib-localized small cell osteosarcomas which was only presented with localized left sided pain. Resection surgery followed by adjuvant chemotherapy was performed. Clinico-pathological features and therapeutic approach are discussed in the light of the relevant literature.

Single versus multiple video-assisted thoracocopic lung biopsy for suspected interstitial lung disease: a perspective on diagnostic efficacy and length of hospital stay.

Background: Nearly one-third of the patients with interstitial lung disease (ILD) require surgical biopsy for a definite diagnosis. Video-assisted thoracoscopic surgical (VATS) biopsy has replaced open lung biopsy, but the number of biopsy required to achieve an accurate diagnose is controversial. Objectives: Our study aims to show that a well-planned single VATS biopsy is as effective as multiple biopsies for the accurate diagnosis of ILD by reduced days of hospital stay. Methods: We included 111 patients with suspected ILD who underwent VATS biopsy in our study. Patients were separated into three groups according to the number of biopsies obtained. The differences between groups for diagnostic yield, mean time for chest tube removal, perioperative complications, and approximate volume per biopsy were analyzed statistically. Results: Eighteen single, 74 double, and 19 triple biopsies were made. Mean times of chest tube removal and hospital stay for single, double, and triple biopsy were 3.5, 4.8, and 6.1 days respectively. The number of biopsy and length of hospital stay was strongly related (p = 0.02), but there was no difference for diagnostic yield between single and multiple biopsy groups (p > 0.05). There was no intraoperative complication or perioperative mortality. In postoperative period, eight patients with multiple biopsies had prolonged air leak. Conclusion: Although classical knowledge suggests multiple biopsies from different locations of the lung are essential, recent reports have shown that the site and the number of biopsy are not as effective as previously thought in achieving the diagnosis for ILD. Our results show that a "single" biopsy, decided with multidisciplinary evaluation, is an effective and safe diagnostic tool, with lesser days of hospital stay. Main novel aspects: 1. The classical knowledge that multiple biopsies should be taken from different regions of the lung in the diagnosis of interstitial lung diseases has changed over time.2. Diagnostic concordance between multiple biopsy specimens is above 85%.3. A "single" biopsy, decided with multidisciplinary evaluation, is an effective and safe diagnostic tool with lower days of hospital stay.

Sleeve resections for squamous cell carcinoma of the lung.

BACKGROUND: Sleeve resection is an advanced technique that was developed as an alternative to pneumonectomy. This study evaluated our cases of sleeve resection for squamous cell carcinoma of the lung and compared the outcomes with the literature reports. METHODS: In total, 26 bronchial, 5 bronchovascular, and 3 vascular sleeve lobectomies were performed between January 2000 and July 2005 in our clinic. Age, gender, operations, postoperative diagnosis and staging, and postoperative morbidity and mortality were evaluated. RESULTS: Sleeve resections were performed in 34 patients. All patients were male, with a mean age of 59.4 years. The operations consisted of 16 right upper, 14 left upper, and 1 left lower sleeve lobectomies and 3 superior sleeve bilobectomies. The most common postoperative pathological staging group was stage IIb (32.3%). Operative mortality was 5.9% (n=2). Postoperative morbidity was 20.5% (n=7), including 4 prolonged air leaks plus empyema, 1 prolonged air leak, 1 postoperative bleeding needing revision, and 1 severe bronchostenosis; of these, 6 had persistent atelectasis. The local tumour recurrence rate was 11.7% (n=4). The median survival time and 5-year survival were 36 months and 42%, respectively. CONCLUSIONS: Sleeve resection proved to be good therapy for lung cancer and has a lower morbidity and mortality than standard pneumonectomies and results in better lung function and quality of life. The anastomosis-related complications are experience-related technical complications and training thoracic surgeons to perform SRs at experienced centres will reduce the morbidity associated with SRs.

Video-Assisted Thoracoscopic Treatment of Coelomic Cysts.

Background: Coelomic cysts are uncommon benign cyctic lesions of the mediastinum. Complete resection of the cyst with surgical treatment is indicated depending on whether the patient is symptomatic or whether the cyst grows during follow-up, or whether the diagnosis is uncertain. Surgical treatment prevents complications, relieves symptoms, and establishes diagnosis. Video-assisted thoracoscopic surgery (VATS) is the best method for excision of these cysts. This approach is safe and effective, has low morbidity, and shortens the length of hospital stay Objectives: We aimed to analyze our experience with coelomic cysts through VATS, reviewing clinical, radiological, and pathological features, early and long-term results of surgical management. Patients and Methods: Between January 2011 and December 2018, 20 patients with coelomic cysts who underwent VATS at our clinic were included in the study. Results: The study included 11 female and 9 male patients with a mean age of 45.6 years. Symptoms were present in 17 patients and 3 were asymptomatic. The average cyst diameter was 5.4 cm (range 2-8 cm). Fourteen of them were right sided, the others were left sided. There were no operative mortality and complications. Postoperatively there were no complications, in all cases course was uneventful, all of them were discharged after a mean of 3 days (range 2-6 days). Conclusions: Considering the low complication rate and hospital stay, excision of coelomic cysts through VATS is extremely safe and comfortable, so it should be considered the primary therapeutic procedure.

Surgical treatment of bronchiectasis: Our 23 years of experience.

BACKGROUND: In this study, we aimed to evaluate the success of surgery and a complete resection for bronchiectasis treatment and to present our 23 years of surgical experience. METHODS: Between January 1991 and December 2013, a total of 1,357 patients (667 males, 690 females; mean age 30.5±14.3 years; range, 3 to 73 years) with the diagnosis of bronchiectasis who underwent pulmonary resection in our clinic were retrospectively analyzed. Demographic and clinical characteristics of the patients, etiologies, symptoms, localizations, surgical procedures, and long-term follow-up results were evaluated. RESULTS: There were 1,394 surgeries, as 37 (2.7%) patients had bilateral disease. The surgical procedures included lobectomy (n=702, 50.3%), pneumonectomy (n=183, 13.1%), segmental resections (n=114, 8.2%), bilobectomy (n=83, 6.0%), and lobectomy + segmentectomy (n=312, 22.4%). During the postoperative period, 1,269 (93.5%) patients were followed at a mean duration of 51.6 (range, 1 to 120) months. After surgery, 774 (61%) patients were asymptomatic, 456 (35.9%) showed an improvement, and 39 (3.1%) had no response or deterioration. CONCLUSION: The surgical treatment plays an important role in the clinical and symptomatic improvement of patients with bronchiectasis. Surgery reduces the morbidity and mortality rates with careful preoperative preparation and appropriately selected cases.

Is the treatment for osteochondrolipomas and lipomas the same? Case report and review of the literature on osteochondrolipoma of chest wall.

Lipomas containing bony and chondroid areas are called osteochondrolipomas. Osteochondrolipomas are extremely rare and their treatment is not known exactly. In this article, we report a 41-year-old male patient who had a 45 mm long subcutaneous mass in the chest wall which was detected 15 years before. When the mass started to grow recently, the patient was admitted to our hospital. Total excision was performed to the mass of the chest wall. According to the histopathological examination of the material, the lesion was an osteochondrolipoma. It might be challenging to diagnose such rare osteochondrolipomas in the tru-cut or small biopsy specimens. Differential diagnosis may be challenging clinically, radiologically, and histopathologically. To our knowledge, this is the fifth case of a totally excised osteochondrolipoma of the chest wall which was reported in the literature.

Could SUVmax be an auxiliary parameter in the clinical management of pulmonary hydatid disease?

OBJECTIVE: The aim of this study was to investigate the role of 18F-fluorodeoxyglucose positron emission tomography/computerized tomography (FDG-PET/CT) in the diagnosis and treatment of pulmonary hydatid disease and also compare the morphological characteristics of the lesions with SUVmax values and identify complicated disease. METHODS: Thirty-six patients with a diagnosis of pulmonary hydatid disease who underwent 18F-FDG PET/CT imaging were included in this retrospective study. The size of the lesions, morphological characteristics, accompanying parenchymal and pleural findings, SUVmax and HUmean values and FDG uptake in mediastinal lymph nodes were noted. The relationship between morphologic properties, SUVmax of the lesions and lymphatic FDG uptake was analysed. RESULTS: A total of 99 lesions of 36 patients were classified as solid (7.1%), cystic (53.5%), semisolid (20.2%) and cavitary (19.2%). Thirty-two of the lesions were encapsulated, 38 of the lesions had border irregularity. Accompanying consolidation was present in 10 cases, bronchial obstruction in 9, pleural thickening in 28 and effusion in 3. There was positive correlation between lesions HUmean and SUVmax values (r = 0.285). SUVmax values were significantly higher in lesions with irregular borders, solid or semisolid type and presence of consolidation, bronchial obstruction and pleural thickening. Also more lymphatic FDG uptake was detected in this group. CONCLUSION: Higher SUVmax values may be a useful parameter in the diagnosis of complicated pulmonary hydatid disease. FDG-PET may provide guidance for determining the priority of lesion for surgery in cases with multiple lesions and may be helpful to evaluate the response to medical treatment.
