Abstract
In order to make a definitive diagnosis of polypoid lesions of the gallbladder and selectaproper operative procedure, 1aparoscopic cholecystoscopy and biopsy were perforrned inseven patients. Laparoscope and three trocars were placed as in ordinary laparoscopiccholecystectomy. Under laparoscopy, another 5 mm trocar with a balloon was transab-dominally inserted into the fundus of the gallbladder, which was held by three graspers.Then the balloon was inflated to fix the trocar, and the gallbladder was filled up withsaline. Either a 5 mm rigid scope or a fiberscope was inserted into the gallbladder throughthe trocar. Then the polypoid lesion was observed and biopsied for frozen section. Thediagnoses were a cancer in one patient, an adenoma in three patients and cholesterol polypsin three patients. A proper operative procedure (open cholecystectomy with lympha-denectomy, 1aparoscopic cholecystectomy or polypectomy) was selected in each patient.The final pathologic diagnosis was the same as the cholecystoscopic diagnosis in allpatients.
