An endoscopic resection of ampullary adenoma (a, b). A probe passed through the ampullary duct/canal (a). Ampullary adenoma with flat (not “rolled/curled”) edges due to appropriate pinning on a cork board; note the darkly colored opening of the duct-arrow (b). A technically optimal specimen after satisfactory pinning and fixation; appears as a flat without curled edges (c). Serially sectioned specimen at 2–3 mm thickness with mapping (d).
