Abstract: 26 cases of cholecystic polypoid lesions had been admithed and operated on from Jan-uary, 1987 to October, 1990. Serial pathological section had been performod. Twenty two cases (84.6%) were benign; Heir average age was 40. 2 years old. Four cases (15.4% ) were malignant, their average age was 65.5 years old. The clinical symptoms of cholecystic poly-poid lesion was similar to those of cholelithiasis. The diagnosis was chiefly dependent upon Betasound and the diagnoltic accuracy was 92.0%, The diagnosis might be wrong when the lesion was associated with gallstone. Both the lesions nature (benign or malignant)and size were closely related to the age of patients. All the benign lesions in this gloup were less than 1.5cm in diameter and more than 1.5 cm in malignant ones. The age of 4 malignant cases were all alove 60 and lelow 60 in kenign group. The depth of cancer invasion and the range of tumor extension were all closely reluted to the paognosis. Three patients in malignant troup whose invasion was not leyond muscular layer and without lymphotic metaslasis, who had leen followed for 6 months to more than one year, were ale alioe, One case with sur-rounding tissul infitrated was died of returrence 10 months ofter operation. The best choice of treatment for benign is simple choleeysteclomy and cholecystectomy with excision of sur-rouding liver tissul and eradication of local lymph glands for mustular infiltrated cases.
