[Laparoscopic cholecystectomy and cancer of the gallbladder].

Performing a series of 960 laparoscopic cholecystectomies we have removed 3 unsuspected gallbladder cancers. In one case we have observed the development of trocar site abdominal wall metastasis twice. After resection and reresection of the metastases the patient is symptom-free in the 14th month. During laparoscopic cholecystectomy if there is a suspicion of gallbladder cancer we have to manipulate with special care to avoid rupture of the gallbladder. In doubtful cases frozen section is mandatory. If the malignant process extends over the serosal layer--conversion and radical-extended operation is recommended.
