title: [Is the laparoscopic approach appropriate for porcelain gallbladder?].
abstract: Contrary to the fears raised in surgical publications of the 1950's and 60's, the prognosis of porcelain gallbladder is not automatically associated with an increased risk of gallbladder carcinoma. Two recent cohort studies have allowed a better definition of the appropriate therapeutic attitude for a patient with a calcified gallbladder. In cases of "true" porcelain gallbladder, i.e., the presence of complete transmural calcification of the entire gallbladder wall, indications for cholecystectomy are based on biliary symptoms, all the more so since choledocholithiasis is often associated with porcelain gallbladder. In the case of partial calcification of the gallbladder, i.e., focal plaques of calcification involving the mucosa, prophylatic operative treatment is indicated. In these cases, the incidence of malignancy is markedly increased (14 times that of a control population). Cholecystectomy can still be performed laparascopically as long as the rules for prevention of peritoneal dissemination of tumor cells are scrupulously observed--the gallbladder should not be opened nor bile spilled, the specimen should be placed in a bag for removal through the abdominal wall, the pneumoperitoneum should be evacuated with the trocars still in place and the specimen should be opened and examined after removal with immediate frozen section pathologic exam if there is any question of tumor.
