[Port site recurrence after laparoscopic cholecystectomy]. / Métastases au niveau des orifices des trocarts après cholécystectomie laparoscopique.

BACKGROUND: Gallbladder cancer diagnosis is usually at a later stage. Only 1% of gallbladder cancers are discovered fortuitously at infra-clinic stage when histological exam of cholecystectomy specimen. Laparoscopic cholecystectomy was realised for gallbladder lithiasis or polyps. Port site metastasis after laparoscopy was reported. The aim of our study is to report our series of port site metastasis complicating gallbladder cancer discovered fortuitously after laparoscopic cholecystectomy. METHODS: From 1 January 1994 to 31 December 2004, 2562 laparoscopic cholecystectomy was carried out. Ten gallbladder cancers were diagnosed than the incidence was 0.39%. RESULTS: Gallbladder cancer diagnosis was carried out by histology in 8 cases, and when port site metastasis in two cases whereas histological exam of cholecystectomy specimen was negative. Recurrence of gallbladder cancer was in port site in 4 cases. The mean rate survival of patients with port site metastases was 19 months.

[Primary hepatic vipoma]. / Vipome hépatique primitif.

Vipoma is a rare neuroendocrine tumor most frequently localized in the pancreas. When it is extrapancreatic, it is most often neurogenic. We report a case of primary extrapancreatic vipoma that is non neurogenic localized in the right liver in a patient with severe diarrhea and hypokaliema. Computed tomography, magnetic resonance imaging, intraoperative tomography and surgical exploration did not show any other extrahepatic primary lesion. The diagnosis was performed by immunochemistry, tumorous cells were positives with anti-VIP antibody. Forty two months after right hepatectomy, the patient was asymptomatic.
