Confocal laser endomicroscopy distinguishing benign and malignant gallbladder polyps during choledochoscopic gallbladder-preserving polypectomy: A case report

In the last decade, confocal laser endomicroscopy (CLE) has emerged as a new endoscopic imaging modality for real-time in vivo histological examination at the microscopic level. CLE has been shown to be useful for distinguishing benign and malignant lesions and has been widely used in many digestive diseases. In our study, we used CLE for the first time to examine the morphology of cholesterol polyps as well as the different parts of normal gallbladder mucosa.
