ABSTRACT
The small bowel accounts for at least 75% of the total length of the gastrointestinal (GI) tract and over 90% of the mucosal surface, however, less than 25% of all GI tract neoplasms and 2% of all malignant neoplasms arise here (1). The first reported case of a small bowel tumor was a duodenal carcinoma described by Hamburger in 1746 (1,2). The annual incidence of small bowel adenocarcinoma (SBA) in the United States is only 3.9 cases per million persons, with a mean age reported between 60 and 70 years (3).
