Disparity between ultrasonographic and pathologic findings of laparoscopically removed gallbladder polyps
Abstract
- Cholesterol polyps are the most common cause of the polypoid lesions of the gallbladder shown by ultrasonography (US). Cholesterol polyps are usually attached to the mucosal surface of the viscus with delicate, filammentous stalks so that they can be easily detached. Recently, laparoscopic cholecystectomy has been introduced to treat various gallbladder diseases. We have experienced four patients with ultrasonographically typical gallbladder polyps, that were not detected in the pathologic specimens removed by laparoscopic cholecystectomy. In each patients, intraluminal suction preceded the laparoscopic cholecystectomy, and the suction was presumed to have resulted in the detachment of cholesterol polyps having delicated and fragile stalks.
