Impact of Radiofrequency Ablation on Malignant Biliary Strictures: Results of a Collaborative Registry.

Background: Radiofrequency ablation of malignant biliary strictures has been offered for the last 3 years, but only limited data have been published.

Aim: To assess the safety, efficacy, and survival outcomes of patients receiving endoscopic radiofrequency ablation.

Methods: Between April 2010 and December 2013, 69 patients with unresectable neoplastic lesions and malignant biliary obstruction underwent 98 radiofrequency ablation sessions with stenting.

Increased serum IL-2R levels in coeliac disease are related to CD4 but not CD8 antigens.

Forty-three coeliac children, ranging from 1 year and 3 months to 14 years and 9 months, were studied. Twenty-eight patients were in an active phase of the disease, and 15 were in remission. The criteria of coeliac disease (CD) activity were established according to the results of IgA anti-endomysial antibodies (IgA-AEm).
