Port site metastases following laparoscopic cholecystectomy for unsuspected carcinoma of the gallbladder.

Laparoscopic cholecystectomy is considered as the new gold standard operation for removal of the gallbladder, and has several advantages over the traditional open cholecystectomy. However, in the last few years there is an increasing number of case reports of port site metastases following laparoscopic cholecystectomy for unsuspected carcinoma of the gallbladder. Two case reports of trocar site metastases are presented, and they further highlight the concern of the role of minimal invasive surgery in the presence of unsuspected carcinoma of the gallbladder. In this review we speculate on the mechanisms which may be responsible for metastatic deposits during laparoscopic cholecystectomy and suggest certain recommendations.
