Abstract:
Gastro-intestinal stromal tumors are rare and their evolution is dubious. This observation of port site metastasis after laparoscopic resection of a small duodenal stromal tumor would be, to our knowledge, the first case reported in the literature. Several direct and indirect mechanisms were supposed to be involved in the appearance of metastases after laparoscopic surgery, but the risk of dissemination remains badly evaluated on its frequency as well as on its mechanisms.
