Symptoms often absent until tumor has progressed to produce complication. Even then, presentation vague nonspecific, intermittent pain, obstruction, chronic anemia. The cornerstone contrast radiograph. However, practice about diagnosed radiographically before surgery. This situation further complicated by variety tumors, each with different symptoms manifestations. Surgical excision treatment choice almost every intestinal neoplasm. For simple adequate. In contrast, malignancies, segmental resection including as much adjacent mesentery reasonable, required. duodenum, may necessitate pancreaticoduodenectomy; ileum, right colectomy be case advanced disease, palliative relieve bleeding or obstruction indicated. challenge future will reduce morbidity mortality neoplasms not earlier recognition, therapy but also through development alternative adjunctive patients whom surgical cure possible. require high index suspicion when confronted abdominal complaints an aggressive approach face normal initial studies. addition, multi-institutional trails chemotherapy radiation needed.
