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

Figure 3 Images under probe-based confocal laser endomicroscopy. A: Gallbladder polyp cells were closely arranged and round with a maximum diameter of about 20 μm and black in color; B: Surface of the polyp showed a lack of blood supply, and vascular diameter of about 10 μm was considered; C: The remaining normal gallbladder mucosal cells were round, with nuclei located in the center of the cells, about 5-10 μm in diameter, arranged neatly; D: Normal gallbladder wall microvessel ran in a straight line; E: Mucosa at the fundus of the gallbladder showed sparse cells and fewer microvessels; F and G: Cells of mucous membrane of the gallbladder body were tighter, and microvessels were abundant; H: Oval glandular structure in the mucosa on the neck of the gallbladder, with a size of about 25 μm × 120 μm, with black in the center and a highlighted brush/dot contour at the edges; I: Basal cells were relatively dense, with a diameter of about 5-10 μm.
