Local excision of duodenal gastrointestinal stromal tumor.

摘要

INTRODUCTIONUnlike carcinomas, gastrointestinal stromal tumors (GIST) do not widely infiltrate at the microscopic level and they rarely metastasize to lymph nodes. Therefore, when technically feasible, a local excision is appropriate. Duodenal tumors represent a special situation because of the anatomical constraints imposed by neighboring structures. This is particularly true in tumors of the second and third parts of the duodenum. A case is described which illustrates the factors which contribute to operative decisions on the extent of resection.
