Diagnosis of a mucinous pancreatic cyst and resection of an intracystic nodule using a novel through-the-needle micro forceps

Abstract

Pancreatic cystic lesions (PCLs) are detected in over 2 % of patients who undergo computed tomography (CT) and magnetic resonance imaging screening [1] [2]. Most PCLs are harmless, but some have the potential for malignant transformation. The management of PCLs is challenging, with high resource use. The standard option for the acquisition of cellular material from PCLs is endoscopic ultrasound (EUS)-guided fine-needle aspiration (FNA). Although many types of needles are available [3], it is usually not possible to obtain a reliable biopsy from the cyst wall for a more certain histological diagnosis. In four recently reported cases, a through-the-needle forceps was used to obtain biopsies from PCLs [4] [5] [6]. We report the first case in which a novel through-the-needle micro forceps (Moray, US Endoscopy, Ohio, USA) ([Fig. 1]) was used to diagnose a PCL, and to biopsy and resect an intracystic nodule.
