Port-site metastasis after laparoscopic resection of a duodenal stromal tumor.

Gastro-intestinal stromal tumors are rare and their evolution is dubious. T his observation of port site metastasis after laparoscopic resection of a s mall duodenal stromal tumor would be, to our knowledge, the first case repo rted in the literature. Several direct and indirect mechanisms were suppose d 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.
