Abstract

49 cases of gallbladder polyp had analysed, who had been treated with laparoscopic cholecystectomy from August 1997 to July 1999 in Department of General Surgery, College of Medicine, Soonchunhyang University. The results were as follows;
(1)Sixty-five percent of the benign gallbladder polyps were less than 10mm in diameter, whereas 77.8% of the malignant gallbladder polyps were more than 10mm.
(2)Sixty-eight percent of patients with benign gallbladder polyp were under 50 years of age, whereas 77.8% of malignant gallbladder polyp patients were over 50.
(3)Sixty-seven percent of patients with malignant gallbladder polyp had biliary symptoms, whereas 36.7% of patients with benign gallbladder polyp had biliary symptoms.
(4)The incidence of gallstones in the malignant gallbladder polyps(44.4%) was higher than benign gallbladder polyps (15.0%).
(5)Sixty-two percent of the benign gallbladder polyps were pedunculated, whereas 71.4% of the malignant gallbladder polyps were sessile.
(6)Only one case of malignant polyp was considered as invasive malignant polyp, which needs further curative operation.
(7)In contrast with open conventional surgery, mean hospitalization was reduced only 3.8±1.4 day and mean operative time was 87.1 ± 28.3 minutes.
From these results, it may be concluded that gallbladder polyp in patients over 50 years, with gallstones, with symptoms, with a diameter greater than 10mm, or showing broad based shape should be resected since malignancy can not be excluded. And with preoperative careful diagnosis, intraoperative frozen biopsy, postoperative meticulous histologic examination and follow up, the laparoscopic cholecystectomy considered to be sufficient if the patient is selected properly.
