RESUMO
There are many congenital anomalies of the lung, some of which have no clinical symptoms and are detected incidentally, while others, particularly in the neonatal and infant period, are recognized by their typical signs, symptoms, and radiological appearance. Some congenital lung anomalies are so important that they can cause the death of the patient if not diagnosed and treated early. Classification of congenital lung anomalies is difficult since these anomalies may be related to the airway, arterial and venous vascular system, pulmonary parenchyma, and primitive anterior intestinal anomalies from which the lung originates, and some anomalies may have several etiologic origins. In this review, all subgroups of congenital pulmonary malformations will be discussed.
RESUMO
BACKGROUND: The most common surgery for non-small cell lung cancer is lobectomy, which can be performed through either thoracotomy or video-assisted thoracic surgery (VATS). Insufficient research has examined respiratory muscle function and exercise capacity in lobectomy performed using conventional thoracotomy (CT), muscle-sparing thoracotomy (MST), or VATS. This study aimed to assess and compare respiratory muscle strength, diaphragm thickness, and exercise capacity in lobectomy using CT, MST, and VATS. METHODS: The primary outcomes were changes in respiratory muscle strength, diaphragm thickness, and exercise capacity. Maximal inspiratory pressure (MIP) and maximal expiratory pressure (MEP) were recorded for respiratory muscle strength. The 6-min walk test (6MWT) was used to assess functional exercise capacity. Diaphragm thickness was measured using B-mode ultrasound. RESULTS: The study included 42 individuals with lung cancer who underwent lobectomy via CT (n = 14), MST (n = 14), or VATS (n = 14). Assessments were performed on the day before surgery and on postoperative day 20 (range 17-25 days). The decrease in MIP (p < 0.001), MEP (p = 0.003), 6MWT (p < 0.001) values were lower in the VATS group than in the CT group. The decrease in 6MWT distance was lower in the MST group than in the CT group (p = 0.012). No significant differences were found among the groups in terms of diaphragmatic muscle thickness (p > 0.05). CONCLUSION: The VATS technique appears superior to the CT technique in terms of preserving respiratory muscle strength and functional exercise capacity. Thoracic surgeons should refer patients to physiotherapists before lobectomy, especially patients undergoing CT. If lobectomy with VATS will be technically difficult, MST may be an option preferable to CT because of its impact on exercise capacity.

BACKGROUND: Significant advances have been achieved in immunotherapy for the treatment of lung cancer. It is known that tumor cells and cells in the tumor microenvironment express high amounts of programmed cell death ligand 1 (PD-L1). These PD-L1s interact with programmed cell death protein 1 (PD-1), causing immunosuppression. The aim of our study is to examine the correlation between the serum sPD-1 and sPD-L1 levels and clinicopathological characteristics in patients with nonsmall cell lung cancer. We also compared our results with the healthy population (control group). METHODS: Thirthy-seven nonsmall cell lung cancer (NSCLC) patients who were operated in our clinic were included in our study. The control group included fifteen healthy patients. The sPD-1 and sPD-L1 levels were measured in serum samples by using the ELISA method. RESULTS: The preoperative sPD-1 and sPD-L1 levels were significantly higher in the study group compared to the control group (44.12 ± 22.25 pg/mL vs. 18.54 ± 6.56 pg/mL; p = 0.001 and 26.15 ± 18.03 pg/mL vs. 10.29 ± 3.08 pg/mL; p = 0.001, respectively). There was a statistically significant decline in serum sPD-1 and sPD-L1 levels at the preoperative and postoperative 1st, 7th, and 30th days following surgical resection (44.12 ± 22.25 pg/mL, 37.86 ± 18.02 pg/mL, 36.33 ± 18.36 pg/mL, 34.14 ± 13.71 pg/mL; p = 0.007 and 26.15 ± 18.03 pg/mL, 20.60 ± 15.50 pg/mL, 18.31 ± 14.04 pg/mL, 13.64 ± 10.60 pg/mL; p = 0.001, respectively).There was a positive correlation between the preoperative and postoperative 30th day serum sPD-1 levels and the tumor size (p = 0.031, r = 0.352; p = 0.024, r = 0.371; respectively). We also found a positive correlation between the preoperative and postoperative 30th day serum sPD-L1 levels and pleural invasion (p = 0.001, p = 0.001; respectively), and the N category (p = 0.015, p = 0.013; respectively). DISCUSSION: We think that sPD-1 and sPD-L1 levels may be used as a potential biomarker for lung cancer screening, prediction of the stage, and besides to detect recurrences and/or metastases following resection in NSCLC following validation with multicenter and larger-scale prospective trials.

INTRODUCTION: Cardiac sympathetic denervation (CSD) is an effective procedure for the treatment of inherited channelopathies. Left CSD has traditionally been recommended as neuromodulation to prevent arrhythmia episodes; however, it is thought that bilateral sympathectomy in combination with Kuntz ablation may have additional effects effective due to the anatomical variability of preganglionic sympathetic fibers. The aim of the study was to share our single-center clinical experience with bilateral thoracoscopic sympathectomy for cardiac denervation in different groups of pediatric patients with malignant arrhythmias. METHODS: Fourteen patients (seven with CPVT, five with LQTS, one with resistant ventricular tachycardia as a sequela of myocarditis, and one with cardiomyopathy and atrial tachycardia) underwent bilateral thoracoscopic sympathectomy for cardiac denervation. RESULTS: In all patients, arrhythmia episodes persisted despite medical therapy, and patients with implantable cardioverter-defibrillator received appropriate therapies. The rate of appropriate therapies was 3.25 per year (1-5 per year) in the year before sympathectomy. No major complications related to the procedure were observed in any of the patients. The QTc interval of LQTS patients decreased from 506.2 ± 16.9 ms before the procedure to 476 ± 28.8 ms after the procedure. The mean duration of follow-up after the procedure was 23.3 months (11-47 months). Only two patients received single episodes of therapy 12 and 22 months after CSD, and one patient had arrhythmic events due to noncompliance to medical therapy. CONCLUSION: Due to the anatomical variability of preganglionic fibers bilateral CSD with Kuntz nerve ablation effective treatment and is a safe option.

INTRODUCTION: Postoperative complications following thoracic procedures are a major cause of morbidity and mortality. Alveolar air leaks and/or bronchopleural fistulas are associated with increased risk of infection, prolonged chest tube, and hospital stay duration and therefore generate economical concern for health care providers. A variety of surgical sealants or adhesives have been introduced to overcome this complication. Since intraoperative BioGlue® application can also cause an inflammatory reaction and mimic tumor recurrence on FDG PET-CT, in the present study we aimed to investigate its potential role in false-positive PET-CT results in patients operated for NSCLC. MATERIALS AND METHODS: Data of six patients who underwent resection for primary NSCLC at our institution (Department of Thoracic Surgery, Hacettepe University Medical Faculty) between January 2015 and December 2018 and had false positivity, due to BioGlue® application, at the bronchial stump in follow-up FDG PET-CT were retrospectively analyzed from a prospectively collected database. RESULT: One of the 6 patients was female and 5 were male. The mean age was 68 years (range, 56-79 years). The average time interval between operation and postoperative FDG-PET imaging was 4.3 months (range, 4-6 months). Follow-up FDG-PET imaging SUVmax values ranged between 3.0 and 9.0 (median: 5.33). All patients have been evaluated by FDG-PET scan following the detection of soft tissue densities at the surgical site suspicious for recurrence at their follow-up chest CT scans. Four patients underwent a bronchoscopic examination, bronchial stumps were examined and multiple biopsies were taken from suspicious nodules or tissues and sent for pathologic examination. Histopathological results revealed inflammation which is compatible with foreign body granuloma, without any suspicion for malignancy, in all cases. Two patients were solely followed-up and subsequent FDG-PET imaging after 3 months revealed complete resolution of FDG uptake. CONCLUSIONS: To avoid unnecessary biopsies or surgical procedures, the possibility of false-positive results due to surgical adhesive product use should be taken into account while interpreting follow-up FDG-PET imaging results and the operative reports should be written in detail, describing which surgical materials used and their exact application sites.

OBJECTIVE: To demonstrate that two lung ventilation under general anaesthesia may also be safely performed to create pericardial window with uniportal video-assisted thoracoscopic surgery. METHOD: The single-centre, retrospective, comparative study was conducted at Bulent Ecevit University, Zonguldak, Turkey, comprised data from March 2011 to March 2018 of patients with recurrent and/or with chronic large pericardial effusions unresponsive to medical therapy and/or to pericardiocentesis and who underwent pericardial window creation with uniportal video-assisted thoracoscopic surgery. Group 1 had data of patients in whom pericardial windows were created under general anaesthesia, while group 2 had patients with two lung ventilation. Parameters compared between the groups were gender, age, operation side, operation time amount of drainage, complication, recurrences and survival. Data was analysed using SPSS 19. RESULTS: Of the 20 patients, 9(45%) were males and 11(55%) were females. Group 1 had 14(70%) patients, while group 2 had 6(30%). The age of patients in group 2 was significantly higher than those in group 1 (p=0.041). There was no significant difference between the groups with respect to gender, amount of drainage, operation time and post-operative complications (p>0.05). There was no recurrence or mortality in either of the two groups. CONCLUSIONS: Pericardial window could be created safely with video-assisted thoracoscopic surgery under two lung ventilation for patients carrying high risk for one lung ventilation.

Thoracotomy is a surgical technique used to reach the thoracic cavity. Management of pain due to thoracotomy is important in order to protect the operative respiratory reserves and decrease complications. For thoracotomy pain, blocks (such as thoracic epidural, paravertebral, etc.) and pleural catheterization and intravenous drugs (such as nonsteroidal anti-inflammatory drugs [NSAIDs], and opioids, etc., can be used. We performed a serratus anterior plane (SAP) block followed by catheterization for thoracotomy pain. We used 20 ml 0.25% bupivacaine for analgesia in a patient who underwent wedge resection for a lung malignancy. We provided analgesia for a period of close to seven hours for the patient, whose postoperative VAS (visual analog scale) scores were recorded. We believe that an SAP block is effective and efficient for the management of pain after thoracotomy.
RESUMO
Complications of percutaneous pericardial catheter insertion for pericardial effusion are rare. We describe a rare complication of percutaneous pericardial catheter insertion that penetrated the stomach and diaphragm before getting into the pericardial sac in a patient with lymphoma. The misplaced catheter was extracted surgically and subxiphoid pericardial tube insertion with pleural pericardial window was performed.
