Background: Port-site metastasis following laparoscopic cholecystectomy with unsuspected gallbladder carcinoma is a serious problem. Gallbladder carcinoma is found in 1% of all biliary tract operations, in most being diagnosed only after histological examination of the gallbladder. The spread of cancer following laparoscopy appears aggressive and widespread, as noticed from re-operation for radical treatment. The pathologic findings of gallbladder were consisting of tumoral and necrotic tissue, indicating of well differentiated adenocarcinoma. Mucosa and submucosa were involved, but no evidence of invasion to muscular layer and gall bladder serosa was found (T1). In this article we present the first of an unusual case of four port site adenocarcinoma metastasis from gallbladder cancer.
Case report: A 63 year old woman underwent laparoscopic cholecystectomy for acute cholecystitis. Thirty months later, she was admitted to the hospital with a complaint of masses at the four trocar sites. A biopsy from the port sites was undertaken and led to the diagnosis of adenocarcinoma metastasis. There is no published report of all four port site metastasis of gallbladder cancer after laparoscopic cholecystectomy.
