Contrast-Enhanced Ultrasonography for Differential Diagnosis of Benign and Malignant Thyroid Lesions: Single-Institutional Prospective Study of Qualitative and Quantitative CEUS Characteristics.

Objectives: To extend and revise the diagnostic value of contrast-enhanced ultrasonography (CEUS) for differentiation between malignant and benign thyroid nodules.

Methods: This single-institution prospective study aims to compare CEUS qualitative and objective quantitative parameters in benign and malignant thyroid nodules. Consecutive cohort of 100 patients was examined by CEUS, 68 out of them were further analysed in detail.

The combination of endoluminal radiofrequency ablation and metal stent implantation for the treatment of malignant biliary stenosis - Randomized study.

Purpose: To analyse whether endobiliary radiofrequency ablation prior metal stent insertion in malignant biliary stenosis show improved survival or stent patency.

Methods: 76 patients with histologically proven malignant biliary stenosis have been enrolled in a prospective, randomized study. In control arm, 40 patients underwent self-expandable metal stent insertion.

Non-invasive prediction of persistent villous atrophy in celiac disease.

Background: Celiac disease (CD) is an immune-mediated enteropathy that is primarily treated with a gluten-free diet (GFD). Mucosal healing is the main target of the therapy. Currently, duodenal biopsy is the only way to evaluate mucosal healing, and non-invasive markers are challenging.

Correlation of survival length after pancreaticoduodenectomy for pancreatic head adenocarcinoma depending on tumor characteristics detected by means of computed tomography and resection margins status.

Pancreatic carcinoma is an aggressive tumor with a grim prognosis. Accurate staging is essential for indicating surgery in patients with borderline resectable tumors. This paper examines the correlation between pre-operation characteristics of tumors found on CT, infiltration of individual resection margins as confirmed by a pathologist, and the survival of patients with resectable pancreatic head ductal adenocarcinoma.
