Management of small subepithelial tumors by endoscopic banding without resection and single-incision needle-knife-assisted biopsy sampling: a prospective multicenter study.

Background And Aims: Endoscopic band ligation (EBL) without resection combined with single-incision needle-knife (SINK) biopsy sampling may have a positive impact on small GI subepithelial tumor (SET) management, but the method needs to be tested. The aim was to evaluate the feasibility of this strategy in small-sized SETs.

Methods: This prospective multicenter observational cohort study in 7 centers included patients with SETs ≤15 mm (confirmed by EUS) between March 2017 and March 2020.

Diagnostic accuracy of ultrasound and fine-needle aspiration in the study of thyroid nodule and multinodular goitre.

Objective: Ultrasonography and cytology obtained by fine-needle aspiration are part of the basic study of the thyroid nodule. Although they are not diagnostic in every case, they are cost-effective methods that inform surgical treatment and its extent. The purpose of this study was to evaluate the accuracy of ultrasonography associated with fine-needle aspiration to predict malignancy in nodular thyroid pathology.
