Laparoscopic cholecystectomy and unsuspected gallbladder carcinoma.

Gallbladder cancer is a relatively uncommon malignancy in the United States. Its presentation is similar to that of lithic disease of the gallbladder. Laparoscopic cholecystectomy has become the method of choice for removing the gallbladder in most benign conditions. Occasionally, unsuspected gallbladder carcinoma is encountered in association with laparoscopic cholecystectomy. Overall, gallbladder cancer portends a poor prognosis. However, in select cases, a favorable outcome can be expected and the less favorable predicted expected outcome can be improved. Management of patients with gallbladder cancer in different situations is discussed: gallbladder cancer noted postoperatively on final pathology, gallbladder cancer noted after removal of the gallbladder and opening of the specimen at the time of surgery, difficulty encountered at the time of dissection and resultant suspicion of gallbladder cancer, and diagnosis of extensive disease at initial placement of the laparoscope. The technique of extended cholecystectomy is outlined.
