Evaluation of Pancreatic Cystic Lesions Via EUS-guided Fine Needle Aspiration With and Without Micro Forceps Biopsies
Sorry, not currently recruiting here
Pancreatic cystic lesions (PCLs) are a common incidental finding in cross sectional imaging (up to 27% on CT scan and 41% on MRI) and pose a management challenge to physicians. According to society guidelines, PCLs with specific features should prompt additional workup with endoscopic ultrasound (EUS) for cyst characterization as well as cyst sampling. This can help determine if the cyst is mucinous or non-mucinous which has implications for its malignant potential. Cyst fluid has traditionally been sampled using EUS with fine needle aspiration (EUS-FNA) and sent for fluid analysis and cytology. More recently, the adjunctive use of the through-the-scope micro forceps (Moray micro forceps, US Endoscopy, Mentor, OH) biopsy (EUS-MFB) has shown promise for diagnosis of PCLs. This technology utilizes a micro forceps through a 19-gauge needle to biopsy the cyst wall for histology, in addition to collecting cyst fluid for CEA level and cytology. More recently, the adjunctive use of the Moray® through the needle microforceps biopsy (EUS-MFB) has shown promise for diagnosis of PCLs. This technology utilizes a microforceps through a 19-guage needle to biopsy the cyst wall for histology, in addition to collecting cyst fluid for CEA level and cytology. Only a few small retrospective reports have been published regarding the use of MFB. The results of this study will hopefully help increase diagnostic yield by obtaining a histopathologic diagnosis of these PCLs, and potentially affect practice patterns of gastroenterologists and the endoscopic community, specifically those physicians who perform EUS in these patients. Furthermore, the results will help determine whether there is reason to continue this line of research to obtain a definite histologic tissue diagnosis of PCLs.
