Fiducial Marker Placement Via Convex Probe EBUS
The efficacy of low-dose computed tomography screening is likely to increase the number of early-stage lung cancers identified. The aging population, as well as increase in number of patients with multiple comorbidities, suggests that nonsurgical techniques such as stereotactic body radiotherapy will be vital in treating such malignancies. Convex probe endobronchial ultrasound facilitates the identification of mediastinal and hilar lymph nodes, in addition to central lung tumors. Using a simple modification of the transbronchial needle aspiration technique, we describe a method for placing fiducial markers into isolated central tumors that ensures appropriate localization for definitive radiotherapy.
Conclusions: Our study indicates that solid nodules have the highest risk of malignancy. Furthermore, the cytological evaluation of subsolid and partially calcified nodules is crucial for the accurate diagnosis and appropriate clinical management of lung nodule patients.
AbstractThe incidence and mortality rates of pancreatic cancer, which has a poor prognosis, are rising rapidly. Endoscopic ultrasonography (EUS) provides superior spatial resolution compared with other imaging modalities such as transabdominal ultrasound, computed tomography (CT), and magnetic resonance imaging (MRI), and it is considered among the most reliable and efficient diagnostic modalities for pancreatic diseases. In this review, we show that EUS is useful for detection of pancreatic solid lesions and staging of pancreatic cancer. EUS also plays an important role in screening patients with high-risk factors for pan...
This study was performed in order to define the prevalence of mediastinal LN metastases discovered on combined endosonography by endobronchial ultrasound (EBUS) and endoscopic ultrasound (EUS) fine needle aspiration in patients with a radiologically normal mediastinum. This study consists of a retrospective, single-institution, tertiary care referral center review of a prospectively maintained database.
CONCLUSIONS: Review authors found a disappointing lack of evidence on the accuracy of imaging in people with a diagnosis of melanoma at different points on the clinical pathway. Studies were small and often reported data according to the number of lesions rather than the number of study participants. Imaging with ultrasound combined with FNAC before SLNB may identify around one-fifth of those with nodal disease, but confidence intervals are wide and further work is needed to establish cost-effectiveness. Much of the evidence for whole body imaging for primary staging or re-staging of disease is focused on PET-CT, and compa...
Conclusions: The combination of R-EBUS with C-TBNA was advantageous and safe for the diagnosis of solitary peribronchial pulmonary lesions located in the segmental bronchi. However, possible bleeding complications should be anticipated with needle aspiration. Further verification of this combined application should be investigated in larger clinical trials.
This report emphasizes the significance of pathological confirmation before starting treatment, even in cases with diffuse pancreatic enlargement. PMID: 31178502 [PubMed - as supplied by publisher]
Chronic pancreatitis increases the risk of developing pancreatic cancer. This often presents as a mass lesion, especially in the head of pancreas. However, the mass lesion in the patients of chronic pancreatitis(CP) can also occur secondary to an inflammatory process, as a consequence of CP. These lesions are often identified by conventional computed tomography(CT) abdomen findings. Advanced approach with endoscopic ultrasound(EUS) with techniques like fine needle aspiration(FNA) could be helpful for differential diagnosis in the past when elastography and contrast-enhanced endoscopuc ultrasound (CE-EUS) were not available.
CONCLUSION: This case highlights the importance of defining the US characteristics of rare variants of thyroid neoplasms, since an early diagnosis is decisive in defining the patient's prognosis. PMID: 31140157 [PubMed - as supplied by publisher]
Conclusion: If the thyroid nodule is detected with flouro-2-deoxy-D-glucose uptake, to differentiate benign nodule from malignant, cytological examination is noteworthy to diagnose the more aggressive type of thyroid nodule and also thyroid metastasis from primary cancer.
CONCLUSIONS.—: PET-CT positivity alone was nonspecific for malignancy and insufficient to guide management of patients with mediastinal adenopathy, but specificity could be improved when combined with LN size and standardized uptake value. PMID: 31063012 [PubMed - as supplied by publisher]
